摘要:
为了厘定南堡M断块明化镇组油气富集层位差异的原因,将油气成藏过程细分为油气进入圈闭、在圈闭中运移及在圈闭中聚集三个不同的运聚阶段,分析各阶段油气运聚的动力和阻力差异,结合断块内油气富集层位,明确了南堡M断块明化镇组不同小层油气富集程度差异的原因。研究表明:油气进入圈闭条件和聚集条件的差异是南堡M断块明化镇组油气富集层位差异的主要原因;造成油气进入圈闭和在圈闭中聚集条件差异的主要原因是各小层的输导断层和遮挡断层的断—储排驱压力差;断—储排驱压力差除了受断层断距、储层厚度的影响外,还与相邻地层的岩性组合有关。研究认识对于断块油藏精细滚动开发具有指导意义。
Abstract:
To determine the reasons for the differences in oil and gas enrichment levels in the Minghuazhen Formation of the Nanpu M Fault-block,the process of oil and gas accumulation is subdivided into three different stages of migration and accumulation: oil and gas entering the trap,migration in the trap,and accumulation in the trap. Based on the analysis of the dynamic and resistance differences of oil and gas migration and accumulation at each stage,and combined with the oil and gas enrichment layers in the fault block,the reasons for the differences in the oil and gas enrichment degrees of different small layers in the Minghuazhen Formation of the Nanpu M Fault-block are clarified. The results show that the differences in oil and gas entering the trap and accumulation conditions is the main reasons for the difference in the oil and gas enrichment layers of the Minghuazhen Formation in the Nanpu M Fault-block. The main reasons for the difference in the conditions of oil and gas entering the trap and gathering in the trap are the fault-reservoir drainage and displacement pressure difference between the transport faults and the blocking faults in each small layer. The fault-reservoir drainage and displacement pressure difference is affected by fault distance and reservoir thickness and is related to the lithologic combination of adjacent strata. The research and understanding are significance for the fine-rolling development of fault block reservoirs.
