Loose sand reservoir fracturing proppant grain filling

Loose sand strata fracturing proppant size filling optimizing fracturing technique is implemented in loose sandstone formation, after, if serious proppant embed and sand invasion in frac sand quantities, pack diverting capacity will be greatly, fracture failure acceleration, and both are closely related to the particle size of proppant. Data show that in soft formation, the particle size of proppant on embedded influence is very big, but not for in-depth study. Traditional gravel pack sand control, Saucier rule is not suitable for sand control selection criteria, the site construction, fracturing proppant to enlarge standards, such as 6 ~ 8 times, 7 ~ 9 times, even more is better, but still no unified standard. The author in view of the implementation of king county oilfield fracturing pack two loose sand high permeability reservoirs, through the design of proppant in soft formation embedding and cracks in the wall and the end of the sand contamination test, proppant size optimization. 1 test proppant embedded in soft formation and fracture surface of sand contamination of test device makes full use of FCES - 100 type fracture flow meter, homemade loose sand rock plate, designed to simulate the formation of cracks in the wall embedded and sand contamination test,
