摘要
在对封堵球作用机理研究的基础上,针对川西气田实际情况,建立了投球分压排量控制方程,确定了在不同射孔长度时的控制排量,形成了投球分压最小排量控制技术,并通过现场应用取得了较好的效果,对投球分层压裂设计及施工具有一定的指导意义。
Based on the mechanism of ball-off separate layers fracturing and practical situation of western Sichuan gas field, the flow rate control equation of ball-off separate layers fracturing was established. Based on the equation, the control displacement at different perforation length was determined, and the controlling technique of minimal flow rate for ball-off separate layers fracturing was formed. Through field application, the good effect has been obtained.
