摘要: 在印度板块与欧亚板块的"陆陆"碰撞拼贴构造作用下,滇黔桂地区在喜山Ⅰ、Ⅱ、Ⅲ幕,分别于桂、滇西和滇东—黔南地区,顺大型走滑断裂带形成了一大批始新世—渐新世、中新世和上新世第三期的小型山间走滑拉分盆地.3个地区发育的3期盆地具有不同的构造和沉积演化特征,使各地区盆地具有不同的生物气成藏条件,生物气藏主要分布于桂西和滇东—黔南地区的始新世—渐新世和上新世盆地中.在各盆地中,受沉降速度、沉积相带、烃源岩埋深、断层发育密度、圈闭类型和地层剥蚀程度等控制,各区带的生物气成藏条件也存在明显区别,生物气藏分布在各盆地的深凹及其相邻区带.Abstract: Under the "land-to-land" collision and matching structural action of the Indian Plate to the Euro-Asian Plate, a series of small intermountain strike-slip and pull-apart basins of the Eocene-Oligocene, the Miocene and the third stage of the Pliocene were formed along large strike-slip fault zones in Guangxi, West Yunnan and East Yunnan-South Guizhou areas during the Himalayan Ⅰ,Ⅱ and Ⅲ episodes. Three stages of the basins developed in three areas had different structural and sedimentary evolutionary characteristics, and resulted in different pool-forming conditions of biogases for the basins of each area. Biogas pools mainly distributed in the Eocene-Oligocene and the Pliocene basins in West Guangxi and East Yunnan-South Guizhou areas. In each basin, controlled by fall velocity, sedimentary facies zones, source rock depth, fault developing density, trap types and stratigraphic denuded degree, biogas pool-forming conditions were clearly different in each zone. Biogas pools distributed in the deep sags and adjacent zones of each basin.
