摘要： A method for abandonment of a subsea well includes: setting a packer (37) of a lower cementing tool (35) against a bore of an inner casing hung from a subsea wellhead; fastening a pressure control assembly to the subsea wellhead; hanging an upper cementing tool from the pressure control assembly and stabbing the upper cementing tool into a polished bore receptacle (36) of the lower cementing tool; perforating a wall of the inner casing below the packer; perforating the inner casing wall above the packer by operating a perforator of the upper cementing tool; mixing a resin and a hardener to form a sealant; and pumping a fluid train through bores of the cementing tools and into an inner annulus formed between the inner casing and an outer casing hung from the subsea wellhead. The fluid train includes the sealant followed by a cement slurry.
摘要翻译：放弃海底井的方法包括：将下固定工具（35）的封隔器（37）设置在与海底井口悬挂的内壳的孔上; 将压力控制组件紧固到海底井口; 将上固定工具从所述压力控制组件悬挂并将所述上固井工具刺入所述下固结工具的抛光孔容器（36）中; 在封隔器下面穿过内壳的壁; 通过操作上固定工具的穿孔器对封隔器上方的内壳壁进行穿孔; 混合树脂和硬化剂以形成密封剂; 并且通过钻井工具泵送流体列车并进入形成在内壳和从海底井口悬挂的外壳之间的内环形空间中。流体系包括密封剂，然后是水泥浆。
