【摘要】：近年来我国在四川盆地率先实现了页岩气商业开发,奥陶系五峰组-志留系龙马溪组成为南方海相页岩气开发的主力层系.通过梳理页岩气沉积与分布特征、构造演化特征、构造样式及保存特征、页岩储层特征,提出了我国南方海相页岩气富集高产的主控因素:深水陆棚相富有机质优质页岩是物质基础;构造抬升时间和构造样式是页岩气富集保存的关键因素,总结了构造保存"完整型、残留型、破坏型"3大类页岩气构造样式;地层超压是页岩气高产的必要条件.最终展望了页岩气发展前景,预测了我国南方几个古隆起的边缘和滇黔桂地区是未来页岩气勘探开发的有利区.
[Abstract]:In recent years, China has taken the lead in realizing the commercial exploitation of shale gas in the Sichuan basin. The Ordovician five peak group - Silurian dragon Maxi is the main layer of shale gas development in the southern marine facies. By combing the shale gas deposition and distribution characteristics, structural evolution characteristics, structural styles and preservation characteristics, shale reservoir characteristics, the marine shale of southern China is put forward. The main controlling factors of gas enrichment and high yield are that the rich organic quality shale of deep water shelf is the material base, and the tectonic uplift time and structural style are the key factors of shale gas enrichment and preservation, and the 3 major types of shale gas structural styles are summarized, which are "complete type, residual type and destructive type", and the formation overpressure is the necessary condition for high yield of shale gas. The development prospect of shale gas is forecasted, and the edge of several paleo uplifts in southern China and the Yunnan Guizhou Guangxi area are predicted to be favorable areas for shale gas exploration and development in the future.
