Abstract

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.

Key words: enrichment rule, reservoir characteristics, high quality shale reservoir, deep water shelf, deep shale gas
