限流法完井压裂技术是通过严格控制油层的射孔密度,并尽可能提高注入排量,使最先被压开层吸收大量压裂液而增大炮眼摩阻,造成井底压力大幅度上升,迫使注入的压裂液分流,相继压开破裂压力接近的邻近层,达到一次压裂几个层的目的。
The current-limit method fracturing technology is through the strict control of the perforation density of the reservoir, and as much as possible to improve the injection displacement, the first layer to be pressurized to open a large number of fracturing fluid and increase the friction resistance, resulting in large bottom hole pressure Amplitude increases, forcing the injection of fracturing fluid diversion, one after another cracking pressure near the adjacent layer, to a fracturing several layers of purpose.
