First, the basic principle
This product is based on unsaturated resins, oil-soluble polymers, surfactants, etc., and is used in fracturing steering agent produced by advanced synthetic modification technology. Multi-level distribution, suitable for formations with different permeability. This product can quickly form a barrier with relatively low permeability and a certain strength in the formation, effectively control the fracturing fluid to break up, and change the flow direction and distribution of the fracturing fluid, so as to control fracture height, increase fracture length, The purpose of improving the fracturing effect. When the well is opened for production, the steering agent can be gradually dissolved by the crude oil. After the crude oil is discharged, the formation permeability is restored, which effectively protects the oil and gas layer.
