中国近海近几年油气勘探特点及今后勘探方向

Recent features and future directions of offshore hydrocarbon exploration in China

中海油近几年在中国近海不断加大自营勘探力度,储量发现连年创历史新高。近几年中国近海的油气勘探具有以下特点:坚持寻找大中型油气田的指导思想;转变勘探思路,从区域研究入手,加强领域研究和勘探;坚持针对中国近海地质特点的地质认识创新和勘探技术创新;科学布局,优化勘探风险投资组合;加强中长期勘探规划并指导年度勘探部署。中国近海今后的勘探方向:对于成熟探区,要立足富生烃凹陷寻找大中型油气田,加强对以往钻井资料的重新认识,积极探索新层系和新圈闭类型;对于新区新领域,首先要加强区域研究和基础研究,优选勘探潜力大的领域进行勘探,其次要做好高风险地区风险勘探的准备,同时要加快深水区的勘探步伐。

CNOOC has set historical records in dis- covering hydrocarbon reserves offshore in China in recent years, due to its continuous growth of selfoperated exploration. The recent features of off- shore hydrocarbon exploration in China are as following： （1）To adhere to the guideline of looking for large and major hydrocarbon fields; （2） To transform the exploration strategy into emphasi- zing realm research and exploration by starting at regional studies; （3）To adhere to innovation in geologic knowledge and exploration technique that is suitable to China offshore geology; （4）To optimize risk exploration portfolio by scientific deployments; （5）To strengthen exploration plans of me- dium-long term and apply them to guide annual exploration deployments. For the future directions of offshore exploration in the mature areas, it is needed to looking for large and major fields by taking root in rich hydrocarbon-generation sags, and to probe actively into new formations and new trap types by focusing on reviews of past drilling data. For the frontiers and new realms, the regional and basic researches should be strengthened at first, in order to select the realms with a great potential to be prospected; and then the high risk areas should be at ready for risk exploration, and the deep-water exploration should be speeded up.
