Oil Fracturing Proppant

Matrix for quartz or taoli grain, grain in plating layers high-strength shell. In the outer shell with high strength of different Fracturing Proppant not only has the characteristics of ordinary, but also give special performance.

1. Low density coating support agent: bulk density < 120 g.c m - 3, depending on the density g.c m - less than 2.0 3,69 MPa broken rate is less than 3%.

2 bonding agent: soft sand support can effectively solve the strata movement caused by resin sand layer caused by damage to the problem of sand.

3 by grinding surface: add lubricant and special material, make more smooth and eliminate grain, thereby reducing the fracturing gathered electrostatic equipment and piping of wear and tear

4 water type: the change of plating surface material, make the surface properties of particles, accelerate the flow through the obstacle by ability. Oil In atmospheric water cannot pass, oil can smoothly. In the water under the pressure, and accelerate the oil through through.
Type: high through

5 according to the gas absorption characteristics, change the particle surface coating, coating performance accelerated gas pass.

6 in the sand: temperature and pressure can be closed in liquid bonding curing. Oil Fracturing Proppant can be used not only to control and fracture fracturing and gravel filling sand control. In the fracturing operation, when coating cracks, sand sand into the surface, the first melt temperature after a period of time after consolidation. So, on the one hand, in the sand surface to form a hard shell, not only can significantly improve the ability of crushing sand, and even sand broken folded in film, prevent sand and stratum of crushing sand in the cracks of migration, On the other hand, due to the consolidation in the sand filter layer formed whole, not only prevent sand control, has also played back; Coated shell flexible characteristic can eliminate or reducing agent, support embedded in general and keep improving the crack extension fracture diverting capacity, high validity.
