Ultralow-density water control and oil increment proppant for fracturing
The invention provides an ultralow-density water control and oil increment proppant for fracturing. The proppant formed by curing substances at 85-95 DEG C, and the substances comprise, by mass, 70-80% of a proppant body, 5-10% of a proppant coating agent and 4-10% of a proppant curing agent; and th...

Zusammenfassung: | The invention provides an ultralow-density water control and oil increment proppant for fracturing. The proppant formed by curing substances at 85-95 DEG C, and the substances comprise, by mass, 70-80% of a proppant body, 5-10% of a proppant coating agent and 4-10% of a proppant curing agent; and the proppant body is obtained through reacting, by mass, 0.5-5% of a proppant reinforcing agent, 5-12%of a proppant monomer, 0.5-5% of a proppant crosslinking agent, 0.5-2% of a proppant initiator, 0.3-5% of a proppant anti-agglomerant, and the balance of water. The high-molecular polymer proppant body is adopted, and coated resin is modified with fluorine, so the density is low, the apparent density is 1.05-1.25 g/cm , the viscosity of a sand-carrying fluid is reduced in the fracturing transformation process of a low permeability reservoir, long propping cracks can be easily formed, the use amount of the proppant is reduced, the use amount of a fracturing fluid is reduced, the improvementof the sand ratio is benefit |
