渤海海域经过四十多年的油气勘探已成功开发了一批大、中型油气田,然而还有很多规模较小的油田尚未开发。为了进一步满足社会对石油资源的需求,中海石油(中国)有限公司在渤海湾海域启动了边际油田开发计划并已投入实践。可升降移动式采油平台随之孕育而生,为了满足可升降式移动采油平台生产和生活对海水的需要,可升降式海水塔也投入到了边际油田开发生产中。
After more than 40 years of oil and gas exploration in the Bohai Sea, a number of large and medium-sized oil and gas fields have been successfully developed. However, many smaller oilfields have yet to be developed. In order to further meet the social demand for petroleum resources, CNOOC Limited launched a marginal oilfield development plan in the Bohai Bay area and put it into practice. In order to meet the need of seawater for the production and living of movable elevating mobile platforms, the elevating seawater towers are also put into development and production of marginal fields.
