Hydraulic fracturing of oil and gas wells utilizes the principle of liquid pressure transmission, using high-pressure equipment on the ground to inject viscous fracturing fluid that is more than the reservoir can absorb into the reservoir.As a result, the wellbore pressure gradually increases, and when the formation fracture pressure exceeds,one or more horizontal or vertical fractures will form in the oil layer. It is an important technical measure for increasing production of oil and gas wells and water injection wells at home and abroad.Fracturing fluiddrag reduction and thickening materials have gradually transitioned from guargum systems to polymer products. Our company has developed and produced a variety of series of products suitable for the fracturing of conventional vertical wells and large-scale large displacement horizontal wells.The product can be widely used in groundwater,river and lake water,flowback fluid,seawater,high salinity water and other water quality.
