摘要

永川深层页岩气田经过多年的勘探开发一体化实践,取得了一定的油气成果,但总体表现出不同构造区气井测试产能差异大的特征,制约了该区规模增储及效益开发。为落实该区的高产富集区带,明确勘探开发攻关方向,通过开展构造样式及断裂分布规律的精细刻画,储层特征精细描述,结合地层压力特征及生产规律分析,总结出该区深层页岩气富集的关键因素包括:厚大且稳定展布的优质页岩储层、有利的构造样式、断而不破的小规模断层、相对发育的天然裂缝、相对较大的埋深和良好的顶底板封堵能力。该区整体具有较高的含气丰度和良好的资源规模。

Abstract

After years of exploration and development integration practice, some achievements have been made in Yongchuan Deep Shale Gas Field. However, there is a big difference in productivity of gas well tests in different structural areas, restricting the scale of reserve increment and benefit development. In order to realize a high-yield and enrichment zone in this area and make clear the direction of exploration and development, the key factors of shale gas enrichment in the deep layer of this area, including thick and stable high-quality shale reservoir, favorable structural style, small scale faults without crush, relatively developed natural fractures, relatively large buried depth and good sealing capacity of roof and floor, are summarized through detailed characterization of structural styles and fault distribution rules, detailed description of reservoir characteristics, and analysis of formation pressure characteristics and production rules. In general, this area has high gas abundance and good resource scale.
