摘要: 透镜体低渗透岩性油藏具有砂体分布零散、非均质性强等特点,开发过程中核部水淹严重,扇缘部水驱效果较差。为此,基于油藏工程方法与理论推导,确立了环形井网环距及采油井井距的计算方法并绘制了计算图版,同时,结合数值模拟方法,对透镜体低渗透岩性油藏有效开发的合理井网井距进行了研究。结果表明:基于相控剩余油条件下的核注翼采井网模式,可有效缓解正方形面积注水井网形式注水憋压的难题,进而降低注水难度,提高水驱效率;与正对井网相比,采用注采井数比为1∶2的核注翼采交错环形井网时,油水井流线分布较均匀,开发效果较好;对于3注6采与4注8采的环形井网,当环距为200 m时,最优采油井井距分别为300 m和250 m。该研究成果为透镜体低渗透岩性油藏的持续高效开发提供了理论基础和借鉴。
