Background technology
Fracturing fluid and additive, which are mixed, is pumped into stratum, produces crack, and proppant is carried to seam, is propped up after the row of returning
Support agent makes fracture open.The effect of proppant is to make fracture open after crack is produced, therefore its intensity is most important, proppant
It must be enough to bear clossing pressure.Supporting crack is obtained under the effect of stratum effective stress with keeping long-term higher water conservancy diversion energy
Power is the key of steady output of oilwell.
The percentage of damage of proppant has an impact to supporting crack flow conductivity, so should reach its regulation in the proppant used
It is required that.Because the higher proppant long-term flow conductivity of percentage of damage declines by a big margin, thus at the scene pressure break when preferentially use
The relatively low proppant of percentage of damage can obtain higher fracture condudtiviy.Whether the percentage of damage of proppant is to examine proppant qualified
Major criterion.
