摘要: 陆梁油田西山窑组J2x4油藏为一低幅度构造、砂泥岩薄互层、油水关系复杂的底水油藏。针对该油藏开发初期含水上升快的现状,利用数值模拟方法,对合理注采比、合理注水时机、合理射开程度等油藏的合理技术政策进行了深入的研究。模拟结果确定合理注采比为0.7,1.5年后注水和50%的射开程度可获得较高的采出程度。数值模拟结果对油田实际开发有指导作用。

Abstract: The Xishanyao J2x4reservoir in Luliang oilfield is a typical reservoir with bottom water, characterized by low amplitude structure, sand-mud laminated layers and complicated oil-water relationship. To improve the status that the water cut is raising rapidly, at the early stage of development, numerical simulation
method is utilized to study the reasonable technical policies,such as ratio of water injection and recovery, timing of water injection and perforating level. The simulation results show that the reasonable injection-production ratio is 0. 7, that water should be injected after developing for one and half years, and
that 50% perforating level is optimal. Such results have a good guidance for the development of this reservoir.

Key words: reservoir with bottom-water, numerical simu-lation, technical policies, oil recovery
