北天山山前的博尔通沟断裂、托斯台断裂、四古南斯裂等组成的山前冲断带是准噶尔盆地南缘找油的主要领域。该冲断带为地震剖面资料所证实,是一个断面南倾、倾角上陡下缓的同生断裂,向东延伸,东西长达500多公里。沿冲断带油气苗丰富、有良好的生、储、盖层,可望发现几个油气藏,为此,在进一步加强地震勘探的同时,及时钻探井是当务之急。
Piedmont break in the front of the North Tianshan Piedmont fault belt, the Totesi fault, the four ancient South Cracked piedmont thrust belt is the southern Junggar Basin to find the main areas of oil. The thrust belt, confirmed by the seismic profile data, is a syngenetic fault with a southward dip and a steep slow dip. It stretches eastward for more than 500 kilometers. Along the thrust belt is rich in oil and gas, there are good raw, reservoir and cap rocks, and several oil and gas reservoirs are expected to be discovered. Therefore, it is imperative to timely drill the well while further strengthening the seismic exploration.
