EPS海上工厂整体解决方案研究与应用

Research and Application of the Overall Solution of Environmental Protection Solutions Offshore Plant

为实现十四五期间海上泥浆钻屑减排50%的绿色低碳战略目标,中海油服创新集成多种关键环保处理技术,通过老旧钻井平台改造转型一体化设计,成功打造了国内首个“EPS海上工厂”,实现海上钻井废弃物的实时批量回收处置,同时,具备钻完井液配制功能模块,形成钻完井液的全生命周期资产化管理。主要参数包括:主甲板总面积900 m2,液相舱容900 m3,可变载荷2250 T。根据多种类钻井废弃物回收处置需求,布局了5个功能模块:水基钻井液再生处理模块;水基钻屑分选压滤模块;合成基钻屑热脱附模块;完修井液处理模块和滤液配浆模块,全年回收处置能力超6万吨,实现海上减量超50%,减排效果突出。

In order to achieve the green and low-carbon strategic goal of 50% emission reduction of offshore mud drilling cuttings during the 14th Five-Year Plan period,COSL has innovated and integrated a variety of key environmental protection treatment technologies,and successfully built the first domestic “oil drilling platform” through integrated design of transformation and transformation of old drilling platforms.Environmental Protection Solutions Offshore Factory”,realizes the real-time batch recycling and disposal of offshore drilling waste,and at the same time,has a functional module for preparing drilling and completion fluids,forming a full life cycle asset management of drilling and completion fluids.The main parameters include:the total area of the main deck is 900 m2,the liquid tank capacity is 900 m^(3),and the variable load is 2250 T.According to the needs of various types of drilling waste recycling and disposal,5 functional modules are laid out:water-based drilling fluid regeneration and treatment module;water-based drilling cuttings separation and pressure filter module;synthetic-based drilling cuttings thermal desorption module;completion and workover fluid treatment module With the filtrate pulping module,the annual recycling and disposal capacity exceeds 60,000 tons,and the offshore reduction of more than 50% is achieved,and the emission reduction effect is outstanding.
