摘要
介绍了限流压裂各小层的流量分配、射孔参数与排量组合的计算方法。针对其低密度射孔特点,分析了压后对油井完善性的影响。经现场应用,限流压裂增产效果明显,是低渗透难动用储量开发的重要途径。
This paper mainly introduces computational formulas of flow rate distribution in each injection profile, combination of perforations＇ parameters and flow rate. Also aiming at its characteristics of low density in shooting, it analyzes the effect on consummation of oil well after fracturing. Through practice, and the preferable production effectiveness is achieved. So limited-entry fracturing is a vital approach to develop low-permeability reservoir.
