Rock debris single-point marine discharge system and application method thereof

Abstract

The invention relates to a rock debris single-point marine discharge system. The rock debris single-point marine discharge system comprises a first storage slot, a fixed pipe, a swinging pipe, a second storage slot and an outboard tube. The first storage slot is formed in a cantilever beam and used for storing debris. The fixed pipe penetrates through the side wall of the cantilever beam, and is connected with the first storage slot and used for discharging debris in the first storage slot. The swinging pipe is arranged on the outer side of the cantilever beam, and is fixedly connected with the fixed pipe and used for discharging debris in the fixed pipe. The second storage slot is arranged in a deck, and is connected with the swinging pipe and used for storing debris discharged by the swinging pipe. The outboard tube penetrates through a main hull, and is connected with the second storage slot and used for discharging debris in the second storage slot. The swinging pipe is detachablyconnected with the fixed pipe. The rock debris single-point marine discharge system has the advantages of capable of discharging debris at fixed points, the rock debris single-point marine discharge system can make use of the spare space of an existing device, the space utilization is improved, and occupied space is small at the same time.

Description

technical field [0001] The invention relates to the technical field of marine drilling, in particular to a single-point sea discharge system for cuttings and a method for using it. Background technique [0002] The jack-up drilling platform is an important mobile drilling device in the sea. In order to improve the operating performance and efficiency of the jack-up drilling platform, the current platform needs to be equipped with a mobile cantilever beam system. When the cantilever beam operates in different well positions, the cuttings discharge port changes position with the cantilever beam, so the cuttings generated by the mud circulation system are usually disposed of by connecting a hose at the bottom of the cantilever beam or directly discharging. Due to the limited installation space, the above method is prone to pipeline blockage, which is difficult to clean. [0003] Therefore, there is an urgent need for a cuttings discharge system that can ensure the smoothness ...

AI Technical Summary

Problems solved by technology

Due to the limited installation space, the above method is easy to cause pipeline blockage, which is difficult to clean

[0003] Therefore, there is an urgent need for a cuttings discharge system that can ensure the smoothness and safety of the cantilever beam operation, reduce the occurrence of pipeline blockage, and improve the efficiency of cuttings discharge, but there is no report on this cuttings discharge system at present
