The sand levee has formed during the first fracturing process,considering the effects of sand levee height change with time and on the fluid flow and proppant sedimentation,the fracture extension model of secondary sanding fracturing is established.
在考虑二次加砂前,一次加砂已经在缝中沉降并形成一定高度的砂堤,砂堤高度随时间不断变化对缝中流体流动及后续支撑剂沉降产生影响,在此基础上建立了适用于二次加砂压裂的裂缝延伸模型。
