定向钻技术在穿越临海养虾池中的应用

Application of Directional Drilling Technology in Crossing the Seawater Shrimp Pond

介绍了沧州聚隆化工有限公司二氯乙烷长输管线定向穿越渤海湾河北省黄骅中捷盐场养虾池的施工中,由于地质结构的复杂特殊性,出现管道回拖抱死事故,造成较大经济损失。分析事故原因,提出改进技术措施,最后穿越成功,为以后遇到相似的地层构造进行穿越工作提供了有价值的参考。

This paper introduces the long-distance dichloroethane pipeline of Cangzhou Julong Chemical Co.,Ltd.in the construction of the shrimp pond of the Huangjie Zhongjie Salt Field in the Hebei Province of Hebei Province.Due to the complex and special nature of the geological structure,there is a pipeline back-to-bottom accident.Caused a large economic loss.Analyze the cause of the accident,propose improved technical measures,and finally pass through the success,which provides a valuable reference for the encountering similar stratum construction in the future.
