Drilling riser joint and riser body automatic butting device

Abstract

The invention provides a drilling riser joint and riser body automatic butting device. Clamping jaws are fixed to the two ends of a piston of a hydraulic oil cylinder, a telescopic rod is fixedly connected with a left-right walking lead screw, a detection head is fixed to the top end of the telescopic rod, and the left-right walking lead screw is connected with an asynchronous servo motor; a clamping detection part is connected with an up-down walking lead screw through a transverse support, the up-down walking lead screw is fixed to a vertical support, and the asynchronous servo motor is installed at the top end of the vertical support, and connected with the up-down walking lead screw; a device walking lead screw, a reduction gear and the asynchronous servo motor are fixed to the upper portion of an equipment base, the vertical support is fixed to the device walking lead screw, and the device walking lead screw is connected with the asynchronous servo motor; and front-back walking wheels are fixed to the lower portion of the equipment base, and the front-back walking wheels are matched with a rail. The drilling riser joint and riser body automatic butting device has the advantages that the requirement for straightness of a drilling riser is sufficiently ensured through automatic six-orientation adjusting and rotating, the situation that the drilling riser joints are hoisted to look for the riser body is replaced, the problem that the unfitness of butt joint is high is solved, the production quality and the production efficiency are improved, safety and reliability are achieved, and the safety of butting construction of the drilling riser joints and the riser body is guaranteed.

Description

technical field [0001] The invention relates to the field of automatic docking devices, in particular to an automatic docking device for a riser joint and a pipe body. Background technique [0002] The market for offshore oil and gas exploration and development is growing, the sea area and water depth for oil and gas exploration and development are increasing, and the marine environment is complex. As a necessary product for offshore oil and gas exploration and development, risers are in increasing demand and have higher requirements, especially for the straightness requirements of risers. The straightness of the riser is directly related to the downhole quality and the downhole quality of the inner casing. There have been cases in which a well group could not go down to 100 meters due to the straightness of the riser. The drilling was restarted, the measurement was carried out to confirm, the riser with poor straightness was replaced, and the drilling was repeated. This l...

AI Technical Summary

Problems solved by technology

In the past, due to the straightness problem of the riser, there was a phenomenon that the well group could not go down to 100 meters. The drill was pulled out again, the measurement was confirmed, the riser with poor straightness was replaced, and the drill was run again.

Time-consuming and labor-intensive cost of construction

And there is also the risk of unsafe
