摘　　要：针对油价暴跌,新春采油厂加大了稀油勘探力度,在准噶尔盆地西缘部署的S1-2井获高产工业油流。S1-2沙湾组油层与P2井沙湾组油层地震振幅属性图上均呈顶凸底平的亮点特征,这两口井油层有效厚度均小于4 m,储层地化录井特征和原油物性相似。针对油层薄识别难问题,开展地震资料处理,主频提高到80 Hz以上,精细地层对比,细分砂体,寻找各砂体尖灭带,在寻找地层油藏、构造油藏同时兼探岩性油砂体。Since oil prices have collapsed,Xinchun oil production factory has to expand the exploration effort of light oil. And then S1- 2 well obtained high yield industrial oil flow in the western margin of the Junggar Basin. Shawan Formations of S1- 2 well and P2 well both have characteristics of top highlight and convex flat bottom in the seismic amplitude attribute graphs. And the two wells have an effective reservoir thickness of less than 4 m and similar geochemical logging characteristic and physical property of crude oil. Because of thin oil pay hard to identify,it was studied on seismic data process increasing main frequency to above 80 Hz,fine stratigraphic correlation,subdivision of sandbodies,and seeking pinchout of each sandbody. The stratigraphic reservoir and structural reservoir were searched. Meanwhile,the lithologic sandbodies were explored.
