构造特征对重庆地区页岩气储量品质的影响

Influence of structural features to reserves quality of shale gas in Chongqing region

基于重庆地区构造特征,重点探讨构造类型、断裂特征、保存条件对页岩气储量品质的影响。研究认为:在远离露头区域和断裂密集发育带、盖层厚度大且覆盖面积广、有封堵性好的断层遮挡的背斜核部平缓区和向斜构造低部位区的页岩气藏保存条件有利,储量品质更好。

This paper explores the impacts of the fractural characteristics,preservation conditions and structural types on reservoir quality on the basis of structural features in Chongqing area.The results show that:the anticline and lower part of syncline area which has large cap thickness and wide coverage as well as good sealing fault block,and is away from outcrop and intensive fractural zone often has good preservation condition as well as reserve quality.
