中国海油油气勘探新进展与未来勘探思考

New progress and future exploration thinking of CNOOC oil and gas exploration

地质认识创新和关键技术突破为中国海油油气勘探发现提供了理论指导和技术保障。2022年,通过解放思想、创新认识,加大风险勘探和甩开勘探力度,在渤海海域隐蔽型潜山、环渤中凹陷岩性、琼东南盆地深水深层岩性、顺德凹陷新区、涠西南页岩油、陆上深煤层及海外勘探等十个领域获得重大勘探突破,为中国海油高质量发展奠定了坚实储量基础。同时,针对东方底辟区、超深层潜山及岩性勘探等复杂地震资料,开展以宽方位、高密度、富低频为基础的地球物理技术攻关,形成了具有海油特色的地震采集、处理技术体系。持续加大深水深层低渗储层、陆上深煤层及海上页岩油等压裂技术攻关,形成了针对不同地层的钻井及工程作业技术体系,有利支撑了勘探新领域的突破。并提出了双碳背景下,未来中国海油油气勘探策略及攻关方向。

The innovation of geological understanding and the breakthrough of key technologies provide theoretical guidance and technological support for oil and gas exploration of CNOOC.In 2022,through mind emancipation and understanding innovation,CNOOC intensified risk exploration and common exploration efforts,and made major breakthroughs in ten exploration fields,including subtle buried hill in Bohai sea,lithology exploration surrounding Bozhong depression,deep-water lithology exploration in Qiongdongnan basin,new area in Shunde sag,Weizhou southwest shale oil,onshore deep coal seam and overseas exploration,laying a solid reserve foundation for the high-quality development of CNOOC.At the same time,in view of the eastern diapir area,ultra-deep buried hill and lithology exploration and other complex seismic data,the geophysical technology on the basis of wide bearing,high density,rich low frequency has been carried out,creating a seismic acquisition and processing technology system with CNOOC characteristics.Continued efforts have been made to tackle key fracturing technologies such as deep seated and low permeability reservoirs in deep water,deep coal seams on land and offshore shale oil,forming drilling and engineering operating systems for different formations,which have supported breakthroughs in new exploration fields.In the background of double carbon,the future oil and gas exploration strategy and research direction of CNOOC are put forward.
