The invention relates to an offshore well intervention operation system which comprises an underwater robot, a seabed tractor and an oil pipe roller part arranged on an oil and gas platform, the oil pipe roller part is used for providing continuous oil pipes for intervention operation, and the seabed tractor is connected to the lower portion of the continuous oil pipes. And the underwater robot is used for connecting the coiled tubing passing through the seabed tractor to the seabed blowout preventer. Intervention operation of the offshore oil field is carried out through the coiled tubing carried on the decommissioned oil and gas platform, utilization of the decommissioned oil and gas platform is achieved, and safety and economical efficiency of offshore oil field development are improved; the intervention operation system is carried on the oil and gas platform, so that compared with the prior art, no stand column needs to be additionally arranged, and the economical efficiency of oil field development is improved.

    本发明涉及一种海上井干预作业系统,包括水下机器人、海底牵引器和设置在油气平台上的油管滚筒部分,所述油管滚筒部分用于提供干预作业的连续油管,所述海底牵引器连接在所述连续油管的下部,所述水下机器人用于将经过海底牵引器之后的连续油管连接至海底防喷器。本发明通过搭载在退役油气平台上的连续油管进行海上油田的干预作业,实现了对退役油气平台的利用,提升了海上油田开发的安全性和经济性;本发明的干预作业系统搭载在油气平台上,因此相比现有技术无需另外设置立柱,提升了油田开发的经济性。
