| 摘 要： | 疏松砂岩油藏开发过程中,易形成大孔道,导致注水无效循环,降低注水开发效果.进行大孔道形成机理与预测的研究,有助干指导疏松砂岩油藏大孔道治理,改善开发效果.结合室内实验结果和矿场生产资料,分析了大孔道形成的地质条件、流体条件和开发因素.采用数值模拟方法,研究了地层韵律性、层间渗透率差异倍数、油水密度差、油水粘度比、采液速度等对大孔道形成的影响.经对比分析,建立了综合系数与油藏形成大孔道之间的变化关系,指出可采用综合系数来预测大孔道的形成,并给出了正韵律、反韵律油藏大孔道形成时该值的界限.以孤东油田七区西Ng63+4油藏为例,利用综合系数判断了大孔道的形成,结果与多种测试分析资料吻合程度较高. |
