What is the role of the impermeable membrane in the oil drilling mud pool?

The impermeable membrane and composite impermeable membrane impermeable geotechnical composition data have the advantages of high strength, good anti-seepage function, strong deformation ability, light weight, width, convenient construction and low cost, and are widely used in water conservancy, electric power, metallurgy, environmental protection, urban construction, railway, highway, military industry, agriculture, mining and other fields of anti-seepage engineering.

The impermeable membrane is a thermoplastic non-polar material, and the connection between the corners and the building in the construction is generally the adhesive bonding method, which is difficult to achieve the fantastic result. The method joint strength is too low, only about 40 of the strength of the composite base metal, when encountering the anti-seepage structure of complex shape, because the reserved edge of the workshop of the composite impermeable membrane is limited, the excessive folds of the coil material in laying will form a lot of waste of materials, and also the dense backfill of the soil, the tension is too tight to form a suspension, and it is easy to be swelled. The welding quality of the welding method is affected by many factors such as the thickness of the membrane, temperature, wind, humidity, voltage, cushion flatness and many other factors on the construction site, and the welding width is too narrow, and its strength and water-stopping results are also difficult to guarantee, and the PE composite impermeable membrane and the concrete and metal of the building can not be connected by the welding method.

Therefore, the construction connection technology of PE impermeable membrane directly affects the implementation and use of PE composite impermeable membrane, a new type of geotechnical composition data. The above is based on the relevant content of the impermeable membrane, if you want to know more about oil drilling, please pay attention to the oil bridge.

Specializing in the production of HDPE impermeable membrane, geomembrane.

1.Cleaning the bottom of the well, levitating and carrying cuttings and heavy stones. Keep the bottom of the well clean and the borehole clean. Prevent drill bit repetitive cutting, reduce wear, improve power, and improve ROP efficiency.

2.Cooling drill bits, drilling tools, cooling and smoothing drill bits and drill strings. Reduce the high temperature of the drill bit due to long-term operation, reduce the serious wear of the drilling tool, and improve the service life of the drilling tool.

3.Balance the rock side pressure of the borehole, form a filter cake on the borehole, close and stabilize the borehole. Prevent pollution of oil and gas reservoirs and borehole collapse. There is a certain quality for cementing quality.

Balance (control) formation pressure, stabilize the well wall, prevent blowout, well collapse and well leakage, and prevent the pollution of formation fluid to drilling fluid. Affect borehole rules and downhole safety.

4.Suspended cuttings and weighting agents. Reduce the sedimentation rate of cuttings and prevent sand jamming.

5.It can sink sand and cuttings on the ground.

6.Effectively transfer water power to better help the drill bit crush the rock. Transmit downhole power and transmit power for downhole drilling tools. Hydraulically crushing rocks. The high-speed jet formed by the drilling fluid through the nozzle can directly achieve the effect of crushing or assisting in crushing the rock.

7.Withstand certain gravitational forces on drill pipes and casings. The buoyancy of the drilling fluid on the drilling tool and casing can reduce the load of the lifting system when starting and going down.

Solid control system for drilling fluids.

Drilling fluid pool.

Drilling fluid is the circulating flushing medium used in the hole during the drilling process. Drilling fluid is the "blood" of drilling, also known as borehole flushing fluid or mud.

Drilling fluids can be divided into water-based drilling fluids, oil-based drilling fluids, and gas-type drilling fluids according to dispersed media (continuous phase). Drilling fluids are mainly composed of liquid phase, solid phase and chemical treatment agents. The liquid phase can be water (freshwater, salt water), oil (**, diesel) or emulsion (mixed oil emulsion and reversed-phase emulsion).

Solids include useful solids (bentonite, weighted materials) and unwanted solids (rock). Chemical treatment agents include inorganic, organic and polymer compounds.

According to the composition, drilling fluid can be divided into clear water, mud, non-clay phase flushing fluid, emulsion, foam and compressed air. Clean water is the earliest drilling fluid, which does not need to be treated, is easy to use, and is suitable for intact rock formations and areas with sufficient water sources. Mud is a widely used drilling fluid, which is mainly suitable for unstable rock formations with loose walls, fracture development, easy to collapse and falling blocks, and expansion and spalling when exposed to water.
