干柴沟地区是柴达木盆地西部较有油气勘探前景的地区。以剪切逆冲边界断层控制的湖盆充填序列在第三纪极为发育 ,可划分为 4类沉积体系、3个构造层序及 4个成因层序。每个层序及其体系域具有不同生储性能和圈闭能力 ,其中第Ⅱ构造层序湖进体系域是最好的生油层系 ,高位体系域则为最佳储集层 ,由此形成的下生上储或自生自储的生储盖组合最具生油潜力。 Ganchaigou area is more oil and gas exploration prospects in western Qaidam Basin. The basin fill sequence controlled by the shear-thrust boundary fault is extremely developed in the Tertiary, and can be divided into four types of sedimentary systems, three structural sequences and four genetic sequences. Each sequence and its system has different reservoir properties and traps, of which the structural system of the second tectonic sequence is the best oil-bearing system and the high system system is the best reservoir. The next generation or self-storage on the reservoir-cap combination of the most productive potential.
