Deep Basin Gas Accumulation in the Upper Triassic of Chuxiong Basin

摘要: 楚雄盆地经历了多次叠加和多期改造,但仍存在深盆构造区.上三叠统为海相和海～陆交互相含煤地层,烃源岩以泥岩、页岩为主,也有部分灰岩、泥灰岩和少量碳质泥岩、页岩及煤.煤系气源岩分布广、厚度大、热演化程度高,为楚雄深盆气的形成提供了充足的气源.直接接触的生储组合广布于盆地中,储层致密,对深盆气的聚集和富集成藏十分有利.气源岩在早白垩世中期-晚白垩世中期为湿气主要生成阶段,其后进入干气大量生成时期,成为深盆气形成的重要时期.喜山运动后盆地主体仍处于地下水交替停滞带,深盆气藏存在整体封存条件.从源岩演化程度和直接接触的生储组合来看,上三叠统形成了一个几乎覆盖全盆地的特大型深盆气藏.根据深盆气藏的主控地质因素的分析,可将楚雄盆地划分为深盆气分布区、气水过渡带和上倾含水区三个区带。

Abstract: Depositional settings of the upper Triassic of Chuxiong basin are f aVorable f or the deep basin gas accumulation. The fluVial and deltaic deposits constitute the dominated reserVoir in the deep basin. The numerous and mature coal beds and organic-rich shales associated inti mately With reserVoir rocks throughout the deep basin pro-Vide a prereCuisite f or deep basin gas accumulation. Gas has the tendency to be trapped in the deepest part of the basin and probably occupies loW per meability reserVoirs extensiVely. Gas generated in source rocks,moVed into the adj acent sand layer and then sloWly migrated updi p. The filling process of deep basin gas asted fromthe late Cretaceous to mid- Tertiary time. Gas may be located doWndip of an aCuifer Which outcrops in basin margins. The gas accumulation of the upper Triassic of Chuxiong basin is predicted and interpreted based on the trapping mechanism of deep basin gas reserVoir. The distribution of deep basin gas accumulation in the basin is descri bed according to the key parameters controlling the ulti mate trapping.
