石炭纪是准噶尔盆地构造地质环境的转换时期,陆块的拼合与大量的海湾相伴而生,海陆变迁形成了滨海沼泽,有利于烃源岩发育;裂谷型和岛弧型火成岩并存,构筑了多种类型的储集体。地质环境的变革为盆地石炭系多套烃源岩的发育创造了条件,广覆式的沉积更增加了石炭系的油气资源潜力和勘探空间。石炭系发育多套烃源岩层,有机质丰度高,具备形成大规模油气藏的资源基础。准东-五彩湾地区是现实的天然气勘探区,西北缘逆掩断层下盘勘探潜力较大,盆地腹部及南部油气勘探前景巨大,有望发现大中型油气田,乌伦古地区的勘探潜力也不容忽视。
Carboniferous is the transitional period of tectonic geologic environment in Junggar basin. The combination of the land masses is accompanied by a large number of bays, and the transgression of land and sea forms a coastal marsh, which is favorable for the development of source rocks. The coexistence of rift and island arc type igneous rocks Many types of reservoirs. The change of geological environment has created conditions for the development of multiple sets of Carboniferous source rocks in the basin. Extensive deposition has increased the hydrocarbon resource potential and exploration space of Carboniferous. Carboniferous sets of multiple sets of source rock development, organic abundance, with the formation of large-scale reservoir resource base. The quasi-east-Wucaiwan area is a real natural gas exploration area. There is great potential for exploration in the uprights of the overthrusts in the northwestern margin, and there is a huge prospect of oil and gas exploration in the abdomen and southern basin. It is expected that the exploration potential of large and medium-sized oil and gas fields and the Ulungu region should not be overlooked .
