准噶尔盆地南缘发育三排背斜带。第一排背斜带于印支期形成三叠系油藏,喜山期形成侏罗系油藏。喜山运动使第一排背斜带抬升、破坏,凹陷一侧的侏罗系源岩生成的天然气进入第二、三排背斜带,形成煤型天然气藏,二叠系源岩生成的天然气因上覆盖层巨厚,未能进入上覆地层。呼图壁气田的发现预示着深部地层具广阔的含油气前景。
Three rows of anticlines are developed in the southern margin of Junggar Basin. The first row of anticlines formed the Triassic reservoir during the Indosinian and the Jurassic reservoir during the Himalayan period. The Himalayan movement led to the lifting and destruction of the first row of anticlines, and the natural gas generated from the Jurassic source rocks on the sag side entered the second and third row of anticlines, forming coal-type natural gas reservoirs and natural gas from Permian source rocks Due to the overburden thick, failed to enter the overburden. The discovery of the Hutubi gas field indicates that the deep strata have a broad oil and gas prospect.
