摘　　要：位于新疆北部的布尔津盆地,地表条件复杂,以往只进行了重力、磁力勘查,勘探程度较低。为进一步了解盆地基底结构、盆山关系、隆坳格局,对盆地含油气情况进行评价,针对盆地内部发育山地、戈壁农田、水网沼泽、巨厚沙漠等地形,利用卫片科学选线;做好低降速带调查;不同地形、岩性的激发井深与药量试验,确保激发效果;采集接收道距不宜过大;进行下石炭统勘探时,尽量采用大偏移距。通过上述措施得到了信噪比较高的单炮记录,获得了浅、中、深地层成像清晰的地震剖面,取得了明显的地质效果。Buerjin basin located at the northern part of Xinjiang is characterized by complicated earth＇s surface,with relative low degree of prospecting for its fewer gravity and magnetic surveys.In order to obtain an overall understandings of the basinal basement structure,basin-mountain relationship and uplift-depression framework,as well as appraise its petroleum prospect,the efforts have been made,including designing physical points of the ground by means of high precision digital satellite map for low velocity zone surveying,scientifically shooting depths and charges,small receiver interval for collection and large offset for the Lower Carboniferous in terms of a variety of landforms in this basin.The obvious results show that single-shot record is of high signal-to-noise ratio,and the seismic profiles with clear imaging from the shallow,medium and deep strata have been obtained.
