The invention relates to a one-piece double-moon pool operation system and a using method thereof. The system is arranged in the middle of a ship body and comprises a blowout preventer set crane, a blowout preventer set trolley, a trolley converter and a one-piece double-moon pool, the one-piece double-moon pool is formed by combining a small moon pool and a large moon pool, trolley rails are longitudinally arranged on the two sides of the one-piece double-moon pool, the blowout preventer set trolley is arranged on the trolley rails and can longitudinally move along the trolley rails, a crane rail is transversely arranged at the tail of the one-piece double-moon pool, and a blowout preventer set crane is arranged on the crane rail and can transversely move along the crane rail. Requirements of marine riser-free mud closed circulation drilling operation and traditional marine riser drilling operation can be met at the same time, laying and recovery of underwater equipment and suspension of a mud return pipeline in two drilling operation modes are achieved, the requirement for a waterline opening is small due to the arrangement of the connected double moon pool, the stability of a ship body is improved, and overall arrangement of a main deck is facilitated. The whole system is simple in equipment and high in compatibility, and the investment cost is reduced.
本发明涉及一种连体双月池作业系统及其使用方法,该系统设置于船体中部,包括防喷器组吊机、防喷器组台车、台车转换器、连体双月池,连体双月池由一个小月池和一个大月池组合在一起,连体双月池两侧均纵向设置台车轨道,防喷器组台车置于台车轨道,并可沿所述的台车轨道纵向移动,连体双月池尾部横向设置吊机轨道,所述防喷器组吊机置于吊机轨道,并可沿所述吊机轨道横向移动。本发明能够同时满足无隔水管泥浆闭式循环钻井作业和传统隔水管钻井作业要求,实现两种钻井作业模式下水下设备的布放回收以及泥浆返回管线的悬持,连体双月池的设置对水线开口需求小,提高船体稳性,利于主甲板总体布置。整套系统设备简单,兼容性强,降低了投资成本。
