摘　　要：根据地震反射特征，结合区域构造、钻井取心资料分析，确认塔里木盆地满加尔凹陷古生代地层中发育的侵蚀凹槽，是等深流作用的结果，其中的充填物主要是由等深积岩组成并有少量浊积岩。这种等深积岩，由于距油源近，砂层发育且具有良好的泥宕封盖条件，因而具有良好的含油气远景，应作为该区的油气勘探对象。Based on the analysis of seismic reflection characteristics, regional struc-ture and core data, it is believed that the erosion trough developed in Paleozoic strata ofMangar sag in Tarim basin was resuIted from contour current.The deposit primarily consists of contourite with a small amount of turbidite. This contourite is near the source rockand is composed of well-developed sandstone with stable shale cap. Therefore it is of hy-drocarbon prospectiveness and can be regarded as the object for exploration in this area.
