摘要
勒3区块等低效油田,油藏埋深浅、温度低,为降低伤害,研制出弱交联压裂液体系,加快了破胶速度,有效降低了残渣及滤饼引起的裂缝伤害。同时,明显降低了压裂液成本,现场应用取得了较好的效果。
For low efficiency oilfield like Shanle block 3, with shallow reservoir buried depth and low temperature, in order to reduce the damage, weakly crosslinked fracturing fluid system was developed, which accelerated breaking and effectively reduced the fracture damage resulted from residual and mud cake. At the same time, fracturing fluid cost was obviously reduced and good field application effect had been taken.
