摘要
台北凹陷前侏罗系是目前吐哈盆地获取新增储量最有利的接替区,但因埋藏深,地震反射信号弱,层位难以识别和追踪而无法确定源岩分布及生烃规模.通过对鲁克沁构造带稠油的油源分析,证实了台北凹陷深层不仅存在二叠系生油岩,而且生烃潜力及资源规模巨大,并已发生过多期油气生成、聚集.
The pre-Jurassic formations of Taibei depression in Turpan-Hami basin are the most favorable exploration areas, but the distribution and hydrocarbon-generating scale of source rock formations are still unclear because of their great burial depth, poor seismic signal, difficulties in indentifying and tracing the strata. The analysis of source rocks of Lukeqing heavy oil reveals that the Permian source rocks not only exist, but also have great hydrocarbon generating potential, and have undergone several phases of hydrocarbon generation and accumulation.
