水下泥挂系统回接至生产平台是海洋石油钻完井工程中的一项特殊工艺,可缩短油气田的建设周期,减少钻井成本,提高海上边际油气田的开发经济效益。东海某气田开发过程中,利用探井临时弃井的水下泥挂系统,通过回接至生产平台,成功将一口探井转化为开发井,取得了良好的经济效益,为海上边际油气田开发提供了借鉴。 The connection of the underwater mud-hanging system to the production platform is a special process in offshore oil drilling and completion engineering, which can shorten the construction period of oil and gas fields, reduce the drilling cost and improve the economic benefits of development on marginal offshore oil and gas fields. During the development of a gas field in the East China Sea, the underwater mud-hanging system of temporary abandonment of exploration wells was used to convert a exploration well into a development well by switching back to the production platform, which achieved good economic benefits and provided a reference for the development of offshore marginal oil and gas fields. .
