针对乌里雅斯太凹陷南洼槽储层物性差、非均质性强、油藏类型以岩性和地层油藏为主的低渗透油藏特点，以沉积储层为主要研究内容，通过层序地层学方法和储层预测新技术的应用，识别出多个不同时期、不同类型的砂体，圈定了砂体范围，预测了有利储层部位。在3年的勘探实践中，先后钻探了10余口探井，全部获得成功，勘探取得了重大突破。

Considering the poor physicochemical property, its non-uniformity, and low permeability of mainly lithologic and stratigraphic pool of reservoir type in the southern depression of Wuliyasitai sag, the sedimentary reservoir is studied in this paper, using sequence stratigraphic methods and new technique of reservoir prediction. Many sandstone bodies of different periods and different types are identified, the range of the sandstone bodies is determined, and the reservoir position is predicted. In recent three years, ten wells were drilled with success.
