The placement law of composite particle size proppant in main fracture for multi-stage combined sanding process
Keywords:
composite particle size proppant, height of the sandbankAbstract
The placement law of proppant in fractures determines the conductivity of hydraulic fractures and the stimulation effect of oil wells. The combined sand paving experiments of 40~80 mesh proppant and 80~120 mesh proppant in the main fracture were conducted with self-designed visual parallel plate fracture model at different injection positions(upper, middle and bottom) and different Injection sequence (large particle size to small particle size and small particle size to large particle size) when the field pumping rate was 4. 96 m3 / min. respectively, and the effects of injection position and injection sequence on proppant placement were evaluated by four parameters, the height of the sandbank at the fracture entrance hp, the balance height of the sandbank Hp, the proppant placement rate at fracture front Rfp and the proppant placement rate at total fracture Rtp , the contribution of each particle size proppant to the propping effect was analyzed by their filling ratio of in the fracture front and the total fracture simultaneously.
