摘要: 准噶尔盆地是西部大型复合叠加含油气盆地之一,油气资源丰富;而天然气探明率仅为3.96%,明显不均衡,勘探潜力巨大。准噶尔盆地天然气藏多表现为高成熟烃源岩油气系统内近源成藏、继承性构造隆起成藏、沿沟通深部气源断裂成藏、区域盖层之下成藏。依据盆地天然气气藏成藏特点,结合盆地构造演化特点与近期勘探成果,基本明确了准噶尔盆地天然气勘探领域:①陆梁隆起东部—五彩湾凹陷—白家海凸起石炭系;②中央坳陷莫索湾凸起—莫北凸起—陆梁隆起西部侏罗系;③山前冲断带上白垩统与古近系;④中央坳陷莫索湾背斜深层石炭系与二叠系。

Abstract: Junggar Basin is one of the large-scale composite superposition petroliferous basins in west China. It features in abundant oil and gas resources, great prospect for exploration, but unbalanced gas exploration. Based on analyzing such characteristics forming gas reservoirs as the features and distribution of gas source rocks, distribution of gas reservoirs and gas source areas, gas reservoir distribution and faults, main periods for forming gas reservoirs, and gas accumulation types, as well as the structural evolution characteristics and recent exploration achievements of the basin, the gas exploration areas of the basin are basically identified, including the Carboniferous of eastern Luliang uplift-Wucaiwan sag-Baijiahai uplift, the Jurassic of Muosuowan uplift-Mobei uplift-western Luliang uplift in the central depression, the Upper Cretaceous and Paleogene of the frontland thrust belt, and the deep Carboniferous and Permian of Mosuowan anticline in the central depression of the basin.

Key words: formation features of natural gas reservoir, exploration potential, exploration area, Junggar Basin
