摘要
水平井与直井混合井网在低渗透油藏开发中获得了广泛的应用。为了确定混合井网的合理井网形式,本文利用数值模拟方法,对不同井网形式下的单井产能、累积产油量、综合含水率等参数进行了研究。结果表明,混合井网开发低渗透油藏以交错井网效果最好。通过分析剩余油分布及地层压力场,进一步证实了交错井网的优越性。
Horizontal-vertical mixed pattern is widely applied in developing low permeability reservoirs. In this paper, in order to establish the reasonable well pattern, features of different well patterns were studied. The results show that interleave well pattern is best when developing low permeability reservoirs. Through analyzing the distribution of residual oil and formation pressure field, it＇s confirmed that interleave well pattern is best.
