柴达木盆地北缘侏罗系残余地层分布极复杂，在其中虽已发现多种类型油气藏，探明石油储量却十分有限。该地区早、中侏罗世沉积了数百米至千余米厚的湖相及沼泽相地层。根据这一地区近年的勘探进展，结合前人工作，认为：①盆地北缘的中生界厚度多为1～2km，主要是侏罗系，埋藏深度多超过4．5km；②侏罗系烃源岩主要是其暗色泥质岩，其次为煤层，母质类型多为过渡型和腐殖型，有机质丰度高，成熟度也较高，油气生成量丰富后储集层系多，主要分布于中、上侏罗统和第三系的下干柴询组、上干柴询组，储集物性较好，有两大类6种类型的生、储、盖组合和油气运聚类型；④侏罗系圈闭以构造背景上发育的多种复合类型圈闭为主，由于难获得良好的深层地震资料，导致辨清圈闭困难，勘探难度大。今后该地区的勘探重点是查清油源层分布和深层圈闭。提出冷湖构造带和马海、南八仙背斜构造带是近期勘探最有利和最现实的地区。
The distribution of residual Jurassic strata in the northern margin of the Qaidam Basin is extremely complicated. Although many types of reservoirs have been discovered, proven oil reserves are very limited. Early and Middle Jurassic sediments in the area range from hundreds of meters to more than a thousand meters thick lacustrine and marsh facies. According to the exploration progress in recent years in this area and the previous work, it is considered that: (1) the Mesozoic thickness in the northern margin of the basin is mostly 1 ~ 2 km thick, mainly Jurassic, with buried depth more than 4.5 km; (2) Jurassic hydrocarbons The source rock is mainly dark mudstone, followed by the coal seam, the parent material types are mostly transitional and humus, the organic matter abundance is high, the maturity is also high, and the rich oil and gas are rich in reservoirs, mainly distributed in Middle, Upper Jurassic and Tertiary Lower Chaiqunshan and Shangganchaikun Formation have good reservoir properties, and there are two types of six types of primary, reservoir and cap assemblages and types of hydrocarbon migration and accumulation. The Jurassic traps dominated by multiple composite traps developed on the tectonic setting. Difficulty in identifying traps was difficult because of the difficulty of obtaining good deep seismic data. In the future, the exploration focus in this area is to find out the distribution of oil source strata and deep traps. It is proposed that the Cold Lake tectonic belt and the Mahai and South Baxian anticline belts are the most favorable and realistic exploration areas in the near future.
