该文针对低渗透油藏压裂水平井，利用油藏数值模拟方法，研究低渗透油藏压裂水平井的产量递减规律、含水上升规律和水驱特征规律等油藏工程。在五点法、七点法注采井网下研究压裂水平井的最终采收率。结果表明：低渗透油藏压裂水平井初期产液量较高，产量递减比较快，而后很快进入缓慢递减、平稳变化阶段；在五点法、七点法注采井网下，低渗透油藏压裂水平井开采的最终采收率在20%左右，七点法井网的含水上升速度更快，五点法井网的最终采收率更高。

Through research on fractured horizontal wells in low permeability reservoir using numerical simulation method,patterns related to reservoir engineering including production decline,water cut increasing and water drive characteristic are analyzed.Ultimate recoveries of a fractured horizontal well in the five-spot well pattern and in the seven-spot well pattern are discussed.The results show that,for fractured horizontal wells in low permeability reservoir,well potential declines drastically from high initial liquid production rate in a short time,and then shows some tendency to level off at a relatively low rate.In the five-spot well pattern and in the seven-spot well pattern,ultimate recoveries are both about 20%,the rate of water cut increasing is higher for the seven-spot pattern,but the ultimate recovery is higher for the five-spot pattern.
