摘要

湘鄂西地区花果坪复向斜中北部、桑植石门复向斜中部的构造改造程度弱

处于古构造的斜坡上

是寻找原生油气藏的有利地区。花果坪复向斜南部以及桑植石门复向斜西部处于古构造斜坡下部

构造改造程度较弱

有望发现继承性油气藏。宜都鹤峰复向斜中部及中央复向斜上部成油组合

因受构造运动强烈改造

志留系盖层被剥蚀

仅存下部含油组合

只能寻找重建型油气藏。

Abstract

Located at the slope of an ancient structure

the weak reformation of the structure in the north central part of Huaguoping composite syncline in the region of Hunan

westernHubeiandthe central part of Sangzhi-Shimen composite syncline is a favorable region for exploring a primary oil and gas reservoir. Located below the slope of the ancient structure

the weak reformation of the structure in southern Huaguoping composite syncline and western Sangzhi-Shimen composite syncline is expected to find an inherited oil and gas reservoir. Only a reconstructive type oil and gas reservoir can be found in the remaining lower part of the oil and gas generation assemblage in the center of Yidu- Hefeng composite syncline and the upper part of the oil and gas generation assemblage of the central composite syncline due to intensively reformed by the tectonic movement and the Silurian roof rock being eroded.
