中国渤海湾海滩－极浅海域油气资源潜力

中国环渤海沿岸众多的油、气田延至海滨,因地表工程环境条件复杂,使油、气勘探开发很困难。但是,该区形成油、气田的石油地质条件十分优越,生油层很发育;储油层系及类型多;生储盖组合配置良好;储油圈闭类型多,构造成带分布;油、气藏类型丰富多彩,油、气田多为多种油气藏纵横叠置立体分布的复合体,形成复式油气富集区。近几年积极采用地震、钻探和海洋工程等新技术全面展开勘探,已在胜利、大港、辽河、冀东油田滩海地区打出了一批高产井,探明了可观的油、气储量,勘探开发的热潮正在形成。

HYDROCARBON RESOURCES POTENTIAL OF BEACH-SUBLITTORAL ZONE IN BOHAI BAY

The coast belt surrounding Bohai Bay of China contains a lot of continental oil and gas fields that extending to the sea. Hydrocarbon exploration and development in this region is very difficult due to the complexity of the earth surface environment. Within the region,petroleum geological condition is particularly favourable for the formation of oil and gas fields. There are well-developed source rocks, multiple reservoir series and types, wellmatched source-reservoir-cap rock assemblages, various kinds of oil and gas tarps and zonaldistributed structures. It is a complex body with multi-type of oil and gas pools that vertically superposed. In recent years, an overall exploration has been carried out by adopting the new technique of seismic exploration, boring and ocean engineering etc., a great number of high production wells in Shengli, Dagang Liaohe and Jidong Oilfieds have been drilled and considerable oil and gas reserves have been found.
