某深水管道清管工艺介绍

Introduction to pigging scheme of subsea pipeline

海底管道铺设完成后进行水下清管和试压,清管试压的工艺选择是油田开发的关键因素之一,需要借鉴国内外的成功经验,进行合理地计算,确定科学的清管试压工艺。本项目根据油田的环境条件和开发成本,确定了合理的清管试压工艺和程序。

After the finish of pipeline layout,pigging and pressure testing should be done.The schemes of pigging and pressure testing are the key point of field development.It is necessary to refer to the successful experience of inland and outland,to calculate logically,and then decide the best scheme.During the development of the oil field project,the rational pigging and pressure testing scheme and procedures are confirmed in the light of environment and development cost.
