Abstract

Based on the research on source-trap space allocation, oil migration transporting form and there controlling effects on reservoir formation and distribution in Putaohua oil layer in and around Sanzhao Depression, it is considered that there are two kinds of source-trap allocation relations in Putaohua oil layer in and around Sanzhao Depression: source rock bottom-trap top and source rock bottom-trap lateral top. And there are 3 kinds of oil migration transporting forms: linear type, reverse “L” type and “U” type. Linear migration transporting form is composed of source faults which pass through T2- T06 reflection layers. Reverse “L” type migration transporting form is composed of source faults which pass through T2- T06 reflection layers and sand bodies connected by faults which pass through T1- T06 reflection layers. “U” type migration transporting form is composed of source faults which pass through T2- T06 reflection layers, sand bodies connected by faults which pass through T2- T06 reflection layers and faults which pass through T2- T06 reflection layers. The controlling effects of these 3 kinds of migration transporting forms in oil accumulation and distribution are showed as follows:①Source faults which pass through T2- T06 reflection layers control the formation and distribution of reservoir which belongs to source rock bottom-trap top space allocation;②The better source faults which pass through T2- T06 reflection layers developed, the more sufficient oil supply which belongs to source rock bottom-trap lateral top space allocation was;③Reservoirs which was formed by source rock bottom-trap lateral top space allocation reverse “L” type migration transporting forms all distribute in or near sand body transporting pathway connected by faults which pass through T1- T06 reflection layers; ④Reservoirs which was formed by source rock bottom-trap lateral top space allocation “U” type migration transporting forms all distribute near faults which pass through T2- T06 reflection layers.
