The invention relates to a drilling and completion operation method and system for a floating production platform with a drilling machine module. The drilling and completion operation method comprises the steps that a drilling vertical pipe and a production vertical pipe are put down at the original point of the platform; after the platform is shifted through the anchor chain, the drilling riser and the production riser are connected with an underwater wellhead, so that the interference risk in the tripping-in process is reduced. According to the method, the well drilling, completion and repair cost and the underwater Christmas tree cost can be greatly reduced, and marginal oil and gas field development can be effectively activated. The method can be widely applied to the field of offshore oil and gas field development.
本发明涉及一种带有钻机模块的浮式生产平台钻完井作业方法及系统,其包括:在平台原点下入钻井立管和生产立管;通过锚链实现平台移位后,再进行钻井立管、生产立管与水下井口的连接,以降低下入过程的干涉风险。本发明能大幅降低钻完井和修井费用、水下采油树费用,有效盘活边际油气田开发。本发明能在海上油气田开发领域中广泛应用。
