准噶尔盆地沙湾组以岩性油气藏为主，存在油砂体规模较小、油层薄、储层岩性变化快等勘探难题。2005年，排2井在沙湾组钻遇油层，日产油49.6 t，地面原油粘度为1.6 mPa·s。立足实践、大胆开拓促成了沙湾组浅层、稀油、高产岩性油藏的突破，高精度三维地震技术发挥了关键作用。车排子地区具有多油源输导、多层系含油、多类型富集、多品位共存的复式聚集特点和“三层楼”油气成藏模式。沙湾组轻质油藏油砂体形态与振幅属性具有较好的对应关系，能够通过地震属性有效识别油水边界。稀油油浸为含油性下限，粉细砂岩为岩性下限，渗透率0.022 μｍ² 、孔隙度 20 ％为物性下限，油层声波时差大于 300 μs/ｍ，电阻率大于1.5 Ω· ｍ，电阻增大率大于 5.5。 已发现沙湾组油藏 23 个。

Shawan exploration of Juggar Basin was faced with exploration problems of small scale oil sand, thin reservoir and rapid changes in lithology. In 2005, Pai 2 Well in Shawan formation drilled oil layer. It obtains 49.6 t/d industrial oil and the ground oil viscosity is 1.6 mPa·s. Practice and boldly exploiting contributes to Shawan's breakthrough of shallow, light oil and high lithologic oil reservoir, and high precision three dimensional seismic technology has played a crucial role. Chepaizi region of Shawan formation has double gathered and the "three floors"  oil and gas accumulation mode of multiple oil source transporting, multi line oil, multi type enrichment and multi-grade coexistence characteristics. Shawan's light oil sand body shape has a good corresponding relationship with amplitude property, and the oil water boundary can be identified by seismic attributes. Oil of thin oil is oil lower limit, and powder and fine sandstone is lithologic lower limit, permeability of 0.022 μm² and porosity of 20 % is lower limit for the properties. Reservoir interval transit time is greater than 300 μs/m, resistivity is greater than 1.5 Ω·m and resistivity index is greater than 5.5. 23 reservoirs have been found in Shawan.
