摘要
根据低渗透油藏压裂现状,将压裂技术与油藏工程相结合,通过数值模拟方法分析了低渗透油田压裂中不规则人工裂缝与排状交错井网的匹配性。研究结果表明,从开采10年的单井日产量、累积产量来看,不规则裂缝的采油井或注水井两侧都未完全压开时的产量要比只压开一侧时的效果要好。同时,未完全压开的井数目越多,对产量的影响越大。
According to the status quo of low permeability reservoir fracturing,combining fracturing with reservoir engineering,through numerical simulation the matching of the irregular artifical fractures and the row-like well network have been analyzed.The results show that for 10 years seeing from the exploitation of the single well daily production,cumulative production,the output of wells or injection wells with irregular fractures which are neither completely open in both sides of the well is better than completely open in one side.Meanwhile the number of wells,is not completely open the greater which are not completely open,the greater the impact on output.
