Abstract

Abstract

The Member 7 in the Longdong area of the Ordos basin mainly develops semi-deep lacustrine-deep lacustrine shale, which is a significant target for tight oil exploration. Based on the sand-ground ratio and lithologic thickness, the source-reservoir structures of submember 7₁ were systematically divided. Based on the rock pyrolysis, hydrocarbon generation thermal simulation and logging data, the source rocks' differences of different source-reservoir structures of submember 7₁ were evaluated, and the influence of source rocks on the oil bearing property of tight sandstone was explored. The results show that the submember 7₁ of Yanchang Formation can be divided into three types of primary source reservoir structures, namely reservoir sandwiching source(Type 1), source reservoir interbedding (Type 2), and source sandwiching reservoir (Type 3). The black shale has better hydrocarbon generation and expulsion ability than the dark mudstone, which leads to the result that the Type 3 structure with high source-land ratio has the best hydrocarbon generation and expulsion, followed by the Type 2 structure and Type 1 structure. The oil bearing property of tight sand in different source-reservoir structure is mainly controlled by the coupling relationship between source rock quality and reservoir physical properties. The high-quality reservoir and medium quality source rock in Type 2 structure make it stable with high oil-bearing property. For the Type 1 structure, the coupling between the high property sand bodies (> 6%) and the adjacent poor source rocks results in the large variation of oil saturation (13%-53%). The poor properties of the Type 3 structure's reservoir limit its oil enrichment.
