What if the world s natural gas was extracted?

If the world's natural gas were to be extracted, it would cause another form of disaster.

I think that if the world's natural gas is extracted, then humanity will face a catastrophe.

If the gas is extracted, the cost of our cooking will increase and life will become inconvenient.

If the world's natural gas is exhausted, we will find other new energy sources.

At present, it is known that the amount of natural gas extracted is far greater than people think, so I think it is unreasonable to worry that the natural gas will be extracted.

Maybe before the time comes, all human life and production have completely gotten rid of natural gas and used all electricity!

Then there is a new continent, and the space of natural gas is filled with seawater and a large continent appears.

People must be looking for something that can replace natural gas, and now that society is developing so fast, I believe that our smart humans will definitely be able to.

Carbon dioxide concentrations in the atmosphere continue to rise, leading to rising surface temperatures and more climate extremes!

Shale gas, combustible ice, these new energy sources. If we look further afield, we may be able to break through controlled nuclear fusion technology (so that we don't have to worry about energy).

And the earth will eventually perish, no matter how long it is, there will be a day of destruction, and there is no solution.

Don't be in a hurry, there are other energy alternatives.

If the world's natural gas is extracted, it is a painful feeling, we will run out of fuel.

If the world's natural gas is extracted, then the world will not survive.

Humanity will destroy itself step by step.

The wisdom of modern human beings can be said to be getting smarter and smarter, and they will definitely be able to find something to replace natural gas.

There is no reason to worry that if the natural gas extraction is not exhausted, human beings will have to use cleaner energy.

If the world's natural gas is extracted, I think the world will definitely collapse.

Natural gas is finished, there is combustible ice, there is shale gas.

The exploitation of natural gas mainly adopts small tubing drainage gas recovery method, foam drainage gas recovery method, plunger gas lift drainage gas recovery method, and deep well pump drainage gas recovery method.

1. Small tubing drainage and gas recovery method.

The small tubing drainage gas recovery method is based on the principle that under a certain gas production, the smaller the diameter of the tubing, the greater the airflow velocity, and the stronger the liquid-carrying capacity. This method is suitable for gas wells with high formation pressure and low water production in the early stage of water production.

2. Foam drainage gas recovery method.

The foam drainage gas recovery method is to add the foaming agent into the well through the tubing or casing, and the foaming agent is dissolved into the bottom of the well and the water reacts with the water to form bubbles, which can not only reduce the relative density of the liquid, but also bring the water produced in the formation out of the ground with the air flow. This method is suitable for gas wells with high formation pressure and relatively low water production.

3. Plunger gas lift drainage gas recovery method.

The plunger gas lift drainage gas recovery method is to put a plunger into the tubing. The flow channel in the plunger is open when it is lowered, and the plunger moves downward under its own weight. When the bottom of the tubing is reached, the flow channel in the plunger closes automatically, and since the pressure acting on the bottom of the plunger is greater than the pressure acting on its top, the plunger starts to move upwards and drains the water above the plunger to the ground.

When it reaches the top of the tubing, the flow channel in the plunger is automatically opened and turns to a downward movement. By reciprocating the plunger, the fluid is continuously discharged. This method is suitable for gas wells with sufficient formation pressure and large water production.

4. Deep well pump drainage and gas recovery method.

The deep well pump drainage gas recovery method uses the deep well pump, sucker rod and surface pumping unit in the well to control the bottom hole pressure through tubing pumping and casing gas production. This method is suitable for gas wells with low formation pressure, especially for the middle and late production of water-producing gas wells, but the operating cost is relatively high.

Features of natural gas extraction:

Natural gas extraction also has its own characteristics. First of all, natural gas, like **, is often a storage system like bottom water or edge water. As the natural gas is extracted, the elastic energy of the water body drives the water into the gas reservoir along the high permeability zone.

In this case, due to the hydrophilicity of the rock itself and the action of capillary pressure, the intrusion of water does not effectively displace the gas, but closes the undischarged gas in the cracks, holes or voids, forming a dead gas zone. This part of the high-pressure gas trapped in the water intrusion zone can be as high as 30% to 50% of the pore volume of the rock, thus greatly reducing the final recovery rate of the gas reservoir. Secondly, after the gas well produces water, the seepage resistance of gas into the bottom of the well will increase, and the total energy consumption of the gas-liquid two-phase pipeline flow along the oil well will increase significantly.

With the increasing impact of water intrusion, the gas recovery rate of the gas reservoir decreases, the self-blowing capacity of the gas well is weakened, and the production of a single well decreases rapidly until the bottom of the well is seriously waterlogged and the production is stopped. <>

Every moment, human beings are consuming a lot of coal, oil and natural gas on the earth, so what should we do when the natural gas on the earth runs out? If the earth runs out of natural gas, we can also use other renewable energy sources, such as biomass energy such as straw, rice husks, peanut shells, wood, or natural renewable resources such as solar energy and hydropower. If you're interested, you can read on.

Natural gas 1. Definition: Natural gas is a fossil fuel, which refers to a class of flammable gases that exist in nature, such as a mixture of hydrocarbon and non-hydrocarbon gases naturally contained in the formation. 2. Importance:

Fossil fuels such as natural gas are an important foundation of modern civilization, and it can be said that without them, there would be no modern civilization. 3. Non-renewable resources: These fossil fuels are the accumulation of the earth over the past billions of years and cannot be reformed in a short period of time, so use a little less.

4. Renewable resources: When the earth's natural gas runs out, we can use renewable resources, such as solar energy, wind energy, nuclear energy, hydropower, and so on.

The first thing to know is why the oil is degassed and burned in the oil opening: fire oil layer Electrical, chemical and other methods make the temperature of the oil layer reach the first ignition point, and inject air or oxygen into the oil layer to make the oil layer continue to burn, which is the fire oil layer. This method is used to mine high-viscosity heavy oil or tar sands.

Its advantage is that it can extract heavy ** and partially crack the heavy oil through combustion to produce light oil. This method has a high recovery rate of more than 80%. Strip Lai Piercing Head.

Almost all oil fields are a mixed type of oil and gas, and a small amount of natural gas is also extracted at the same time as the **. Due to the small quantity, from the economic point of view, there is no value for collection and transportation. However, natural gas is a suffocating gas and is discharged freely will affect the environment and human safety.

What to do? The easiest way to do it, burn it! What kind of gas is burned off?

And why burn it out? In oil exploitation, there is generally associated gas, and the main component is C1 ......There are also some saturated alkanes of C6 that are produced by special gas wells (basically gas). Since the natural gas plant has not yet been built at the time of initial exploitation, for safety reasons (natural gas is flammable and explosive, slightly heavier than air or quite easy to deposit in low-lying places, and has a certain toxicity), it is necessary to vent and burn the natural gas to ensure safety.

The combustion device is called the torch (at this time, regardless of whether the gas treatment device is completed or not, the torch is called the safety torch). With the development of oil and gas fields, there are more and more oil wells or gas wells, and natural gas treatment is necessary to establish natural gas installations after economic accounting and downstream user investigation. China is an oil-poor country, and natural gas processing units should be considered simultaneously in the exploration process and capacity construction to ensure environmental and economic benefits.

Generally, propane and butane are used for liquefied gas for civil and industrial use, methane and ethane are used for natural gas for civil fuel, and pentane and hexane are used for light oil components to chemical devices. It is the natural gas separated from the ** during the production of oil wells, because it has no use value, and it will cause serious pollution to the environment when released into the air, so it is disposed of by direct ignition method!After combustion, natural gas will be converted into carbon dioxide and water, which will have some impact on the earth's atmospheric environment, but plants will absorb carbon dioxide gas.

How is natural gas extracted?Exploration is carried out before extraction, then it is extracted by equipment, and then the gas is transported to various places with gas extraction equipment.

Speaking of natural gas, everyone must be familiar with it, it is a clean and environmentally friendly high-quality energy, and it is economical, safe and reliable, so do you know how natural gas is extracted?

As with oil extraction, natural gas seeps into the bottom of the well and is sprayed out of the surface under the action of the difference between the pressure of the gas layer and the bottom of the well. The difference is that when the pressure drops, natural gas will absorb heat and cool down due to the rapid expansion of volume, which will condense some components into liquid, and even produce hydrate freezing and blockage. The gas layer is also more susceptible to contamination and clogging than the oil layer.

The completion process of gas wells is to use the perforating gun transmitted from the tubing and the negative pressure perforation of low-density perforating fluid after casing cementing, that is, the pressure of the wellbore liquid column is lower than the gas layer pressure during perforation. There is also a kind of near-equilibrium perforation, that is, the pressure of the liquid column of the wellbore is close to the pressure of the gas layer, and a special solid-free perforation fluid is selected to protect the gas layer. After perforation, the air layer and wellbore near the bottom of the well are purified in a controlled manner to purify the gas layer and wellbore.

For low-yield wells caused by gas layer pollution, liquid nitrogen gas lift is used to blow out controllably, and acid is used to deplug if necessary. Note that air must not be used for gas lifting, otherwise the oxygen in the air and the natural gas in the gas layer will be mixed and become a ** gas, which is very dangerous. For the freezing and plugging phenomenon of hydrate caused by gas expansion and heat absorption in the production process, thawing and antifreezing measures such as heating, heat preservation, heat injection chemical agent, and injection of antifreeze agent are adopted, or the well is closed and thawed naturally.

Due to the pressure drop, natural gas expands and absorbs heat, cools down, and partially condenses into liquid, so wellbore fluid accumulation often occurs in gas wells. It is an important measure to maintain the normal production of gas wells to remove the fluid accumulation in the wellbore through irregular controlled blowing, nitrogen gas lift, pumping and other methods. The fracturing stimulation measures of gas wells are similar to those of oil wells, but the difference is that the requirements for gas reservoir protection are higher.
