摘要
油气成藏是一个动力学系统,包括成藏的基本地质条件、动力学条件及其相互之间的有机配合。油气勘探是针对油气成藏特征的一个系统工程。中国海相碳酸盐岩地区油气在成藏条件、成藏过程、油气藏定位等方面表现出相当的复杂性,传统的研究和勘探方法已不完全适合当前问题,目前存在的主要问题是对油气成藏地质特征认识不足、针对性的勘探措施匮乏。根据科学性、实用性和可操作性的原则,提出新的勘探工作应分三个步骤进行:①研究成藏的基本条件;②各成藏条件间有机配合的过程及其结果;③在储集域、压力域、叠置域等六个方面加强钻前预测,并以此为基础指出勘探靶区和相应的技术措施。
Oil-gas pool forming process is a dynamic system that involves basic geological conditions,dynamic conditions and their organic cooperation.The petroleum explora-tion is also a systematic work aiming at the characteris-tic of oil-gas pool forming.The complexity of oil-gas pool forming in marine carbonate area in China showed in forming conditions,forming process,location and other aspects,and the traditional research and explora-tion methods were unsuitable for it.Existing problems today are not enough understanding about the geologic features of oil-gas pool forming and lacking in the suitable exploration measurement.According to the sci-entific,practical and operable principle,a new explora-tion work should be completed in three steps.First,the basic conditions for pool forming should be studied carefully;second, organic cooperation process and re-sult of oil-gas pool forming conditions should be ana-lyzed;the third,predrilling predication should be strengthened on six aspects of the field of reservoir, pressure,superimposition and others,then the explora-tion target and corresponding technical measures could be pointed out based on that.
