综合运用石油地质学和地球化学的理论与方法,对沧东凹陷低熟油生烃机制和资源评价进行了研究。研究结果表明,沧东凹陷共发育两套未熟-低熟烃源岩,烃源岩丰度高、类型好,长期处于低温条件下,烃源岩转化效率高,排烃条件好,具备形成未熟-低熟油形成的先决条件。沧东凹陷低熟油资源总量约1.5～2.1亿吨,剩余资源量巨大,具有广阔的勘探前景。
Comprehensive utilization of the theory and method of petroleum geology and geochemistry, studied the hydrocarbon generation mechanism and resource evaluation of low mature oil in Cangdong depression. The results show that there are two sets of immature-low maturity source rocks in Cangdong Sag. The source rocks have high abundance, good type and long-term low temperature. The source rock has high conversion efficiency and good hydrocarbon expulsion conditions, - Prerequisites for the formation of low-ripened oils. Cangdong depression low-maturity oil resources of about 1.5 to 210 million tons, the remaining huge amount of resources, with broad prospecting prospects.
