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 wells and vertical wells mixed well pattern in the development of low permeability reservoir has been widely used. In order to determine the rational pattern of well pattern in mixed well pattern, this paper uses numerical simulation method to study single well productivity, cumulative oil production, integrated moisture content and other parameters under different well patterns. The results show that the mixed well pattern is the best for the development of low permeability reservoirs in order to stagger the well pattern. By analyzing the remaining oil distribution and formation pressure field, we further confirm the superiority of staggered well pattern.
