摘要
苏里格气田苏6加密井区属于辫状河和曲流河沉积,砂体连续性差。井网井距的合理确定是此类气藏有效开发的关键问题。采用目标区块的实际地质模型,根据实际情况设计了6套井网形式,通过对比不同井网的开发效果确定最佳井网井距。数值模拟研究发现,苏6加密井区的最佳单井控制面积为0.355km2,最佳井距为600m,最佳排距为600～800m。研究结果可为目标区块以及同类区块的有效开发提供技术依据。
Infilled Wellblock Su 6 in Sulige Gas Field belonged to sedimentary facies of braided stream deposit and meandering stream deposit.Poor continuity existed between different sand bodies.To determine rational well pattern was the key of effective development of the gas reservoirs.Numerical simulation was performed for the optimization on the basis of the actual geological reservoir model.Totally six kinds of well patterns were designed according to the actual conditions.Optimal well patterns are established by comparing with the development effects of different well patterns.It is found that the optimal single well control area for Infilled Wellblock Su 6 is 0.355km2,the optimal well distance is 600m and the optimal well line is 600~800m.It provides technical support for effective development of the target block and blocks alike.
