摘要
重复压裂过程中混砂车砂泵的排出压力控制裂缝宽度.重复压裂过程新裂缝周围应力控制复杂,重复压裂的缝宽计算结果与初次压裂的相比存在差别.本文建立了基于复杂压力控制的重复压裂裂缝宽度的计算模型,计算结果与实际结果误差小于7%.
In the process of repeat fracturing, the fracturing width is controlled by the discharge pressure from the sand mixing pump. The stress control around new fracturing in the repeat fracturing process is very complex. There are clifferences between the refraeturing width calculation results and the initial fracturing. Based on complex pressure control. The thesis established the computational model to calculate the width of fractures of refracturing. The error between the Calculated results and the actual results is less than 7%.
