尤尔都斯盆地侏罗系底部发育一套厚约２００ｍ的深湖半深湖相暗色泥岩。这套泥岩的有机质丰度达到了“中好”的评价级别，有机质类型以Ⅲ１型为主，有机质演化处于低成熟阶段，这一切为油气生成奠定了良好的物质基础。盆地内发育着大面积储层和盖层，它与生油层一起形成了良好的生储盖组合。进一步研究表明，区域性构造运动所形成的各种圈闭是油气聚集的主要场所。
At the bottom of the Jurassic in the Jurduss basin, a set of deep-seated lake-lake dark mudstone with a thickness of about 200 m is developed. The organic matter abundance of this set of mudstone has reached the level of “moderately good”. The type of organic matter is mainly Type III1, and the evolution of organic matter is in a low maturity stage, all of which have laid a good material foundation for hydrocarbon generation. A large area of reservoirs and caprocks are developed in the basin, forming a good reservoir-cap combination with the oil-bearing formation. Further research shows that various traps formed by the regional tectonic movement are the main sites for oil and gas accumulation.
