Problems solved by technology

[0002] Traditional drilling platforms cannot be used in the drilling process of shallow rivers. Firstly, inland rivers are not as wide as rivers and seas, and inland rivers have different widths and narrow waters, which makes it difficult for some drilling platforms with excessive width and large drafts to enter. Secondly, there are a lot of garbage and floating objects floating on the water surface of some rivers that have not been fully polluted. During the drilling process of the drilling device, it is easy to enter the drilling and block the drilling rig to affect the drilling process.

Embodiment Construction

[0028] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details. In other examples, some technical features known in the art are not described in order to avoid confusion with the present invention.

[0029] The applicant found that during the drilling process of inland rivers, the drilling ship is facing more frequent problems than offshore drilling, and the traditional river-sea drilling platform cannot be used in the drilling process of shallow rivers. First, the inland rivers are not as wide as rivers and seas. The inland rivers have different widths and narrow waters, which makes it difficult for some drilling platforms with a single width and large draft to enter or cannot be adjusted according to the terrain. Secondly, there are a lot of garbage and fl...

Abstract

The invention discloses an overwater drilling ship and a working method. The drilling ship is of a two-ship-body combined structure and comprises a first ship body, a second ship body and drilling supporting devices arranged on the first ship body and the second ship body. The drilling supporting device comprises a rotating base fixedly installed on the first ship body and the second ship body, aconnecting plate connected to one end of the rotating base in a sleeving mode, and a telescopic rotating arm connected to the two connecting plates. A drilling device mounting plate is fixedly mountedabove the rotating arm; a control system is further arranged on the first ship body and the second ship body, and a control chip and a wireless communication module are arranged in the control system. Compared with a traditional drilling platform, the two-ship-body parallel structure is more flexible, the telescopic rotating arm is hinged between the two ship bodies and can be specifically adjusted according to the specific condition of a river channel, and compared with a single drilling ship, the mode of the two ship bodies has better wind-proof and wave-proof stability.

Description

technical field [0001] The invention belongs to the field of water drilling platforms, in particular to a water drilling ship and a working method. Background technique [0002] Traditional drilling platforms cannot be used in the drilling process of shallow rivers. First, inland rivers are not as wide as rivers and seas, and the width of inland rivers varies, making it difficult for some drilling platforms with excessive width and large drafts to enter. Secondly, there are a lot of garbage and floating objects floating on the water surface of some rivers that have not been fully polluted. During the drilling process of the drilling device, it is easy to enter the drilling and block the drilling rig to affect the drilling process. Contents of the invention [0003] Purpose of the invention: to provide a plate handling auxiliary arm group and a continuous handling method to solve the above-mentioned problems in the prior art. [0004] Technical solution: a drilling ship on...
