摘　　要：复杂小断块油藏难以用规则井网形成完善的注采关系,从而导致油藏能量下降快、水驱采收率低,是制约该类油藏高效开发的关键。此类油藏井网多以不规则三角形井网为主,布井主观而随意,注采关系极不完善,且没有形成1套理论和方法。针对条带形小断块油藏,基于非完善井网完善注采关系思路,考虑不同水体能量,采用数值模拟方法研究了不同井网模式下的油藏开发动态变化特征,给出该类油藏合理的注采井网形式,为此类油藏现场布井开发提供必要的理论和方法依据,进一步丰富了现有井网理论和方法。It is hard to develop complex small fault block reservoir with regular well pattern,which may result in rapid depletion of reservoir energy and low waterflood recovery factor,and restrict efficient development of this type of reservoirs.Irregular triangular pattern is commonly used for such reservoirs,and wells are placed subjectively and arbitrarily,the injection-production relationship cannot be established,and there has not been a methodology formed yet.In this research for strip-shaped small fault block reservoirs,numerical simulation method is employed to study reservoir development performance of different patterns based on the thought of achieving perfect injection-production relationship with imperfect pattern and with consideration of aquifer energy.Rational patterns of injection-production wells are proposed for such reservoirs,thus provided theory and method for developing similar reservoirs,and further enriched existing theory and method.
