中国海相层系油气地质理论的继承与创新

Inheritance and Innovation of Marine Petroleum Geological Theory in China

我国海相碳酸盐岩层系分布面积广,残余厚度大,油气显示多。由于我国海相碳酸盐岩的复杂性和勘探难度大的客观条件,制约了对碳酸盐岩层系油气资源潜力的认识。陆相生油理论的建立以及陆相盆地的成功勘探,使我国的石油工业走上了独立自主发展的道路。中国海相碳酸盐岩油气勘探经历了几多兴奋,几多困惑,勘探实践表明,随着理论认识的升华、科学技术的进步,新发现的海相碳酸盐岩层系油气田越来越多,越来越大,是我国油气资源战略接替的重要领域。中国东部的陆相油气勘探理论及国外海相油气勘探理论均不能有效的指导我国海相层系的油气勘探,海相油气地质理论必须在继承陆相与国外海相油气地质理论基本要素基础上,进一步创新适用于我国海相碳酸盐岩特点的油气地质理论。

Marine carbonate sediments with large-thickness and gas shows are distributed widely in China. Complexity and difficulties of marine carbonate beds restrains our recognition to the appraisement of oil and gas potential. Establishment of terrestrial oil-generation theory and successful exploration in terrestrial basins paved the way for our petroleum industry. With the development of science and technology and further understanding to the theory, more and more oil fields have been discovered within marine carbonate beds, which have become an important oil-finding area in China. Current oil exploration theory developed in eastern China doesn＇t apply to or fail to guides oil/gas exploration in the marine sediments. Therefore, marine geological theory should depend on the terrestrial and foreign marine oil/ gas theories so that an oil/gas geological theory which suits to marine carbonate beds can be established.
