【摘要】：为了寻找含油气盆地下生上储式生储盖组合中油气分布规律,在油气成藏过程及模式研究基础上,对油源断裂与其他成藏要素的空间匹配关系及控藏作用进行了探讨。结果表明:断—源空间匹配关系控制着油气成藏的平面分布范围,其中断—多源空间匹配关系油气最富集,其次是断—单源空间匹配关系,最差为断—无源空间匹配关系;断—盖空间匹配关系控制着油气成藏的纵向分布范围,断接厚度大于封油气所需的最小断接厚度,油气在其下成藏,反之油气在其上、下均有成藏;断—砂空间匹配关系控制着油气成藏的层位,高砂地比地层是油气侧向分流运移和成藏的有利位置;断—圈空间匹配关系控制着油气聚集的部位,油源断裂附近的圈闭易于形成油气藏。
[Abstract]:In order to find out the distribution law of oil and gas in the lower generation and upper reservoir cap rock assemblage in petroliferous basins, the spatial matching relationship and reservoir control between oil source faults and other reservoir forming elements are discussed on the basis of the study of oil and gas accumulation process and model. The results show that the fault-source spatial matching relationship controls the plane distribution range of oil and gas accumulation, and the interrupt-multi-source spatial matching relationship is the most abundant, followed by the fault-single source spatial matching relationship, and the worst is the fault-passive spatial matching relationship. The matching relationship between fault and cap space controls the longitudinal distribution range of oil and gas accumulation. The disconnection thickness is greater than the minimum disconnection thickness needed to seal oil and gas, and oil and gas are formed under it, on the contrary, oil and gas are formed in the upper and lower parts of the reservoir. The fault-sand space matching relationship controls the horizon of oil and gas accumulation, and the high sand-to-ground ratio formation is a favorable position for lateral shunt migration and accumulation of oil and gas. The fault-circle space matching relationship controls the accumulation of oil and gas, and the trap near the oil source fault is easy to form oil and gas reservoirs.
