通过对油气运移的受力状态进行分析 ,探讨了不同类型砂岩透镜体油藏聚油机理 ,根据砂岩透镜体油藏与烃源岩之间的相对位置关系将其划分为源岩内和源岩外两种模式 ,认为毛细管力是源岩内砂岩透镜体聚油的主要动力 ,而排烃压力、浮力等动力大于毛细管力、粘滞力等阻力是源岩外砂岩透镜体油气聚集的必要条件。典型实例分析对寻找砂岩透镜体油藏有一定的指导意义。 By analyzing the stress state of hydrocarbon migration, the mechanism of oil accumulation in different types of sandstone lens reservoirs is discussed. According to the relative position relationship between sandstone lens reservoir and source rock, this paper divides it into source rock and source rock The two modes are considered to be capillary force, which is the main driving force of the sandstone lens oil in the source rock. However, the hydrocarbon expulsion pressure, buoyancy and other dynamic force is greater than capillary force and viscous force. The typical case analysis is of guiding significance for finding sandstone lens reservoirs.
