摘要
分析了柴达木盆地北缘潜西区域地质条件及构造格局,总结了该地区油气成藏模式。研究表明潜西成藏的关键是具有与油源沟通的输导系统、圈闭特征与断层封堵控制油气聚集的区块,而有利沉积相带(储层发育带)是圈闭中油气富集的主要部位。在此基础上建立了6种成藏模式,并分析了各圈闭可能的成藏模式,最后对较有利勘探目标进行了评价。
This articale analysed the regional geology conditions and structural pattern in north edge of Qaidam basin Basin,concluded oil and gas gathering rule. Study showed that the critical conditions for accumulation in Qian-XI area is the migration system connected with petoleum sources and trap features and accumulation area controlled by fault traps, whereas, favorable sedimentary facies streak （reservoir development zone） is the main acculation area. Basing on this,established 6 types of reservoiring patterns, and analysed the potentional reservoiring patterns for every trap,the last,worked out the evaluations for the more advantaged prospects.
