Description

Pipe assembly system for oil and gas drilling. {oil and gas drilling for pipe assemmbly system}

The present invention relates to a pipe (pup join flow line pipe) used in oil and gas drilling and related service lines, and more particularly, to a non-pressure seal type flow line pipe (NPST (none-pressure seal type) Pup joints flow). It relates to a system for assembling line Pipe}.

Since long ago, the amount of resource mining has been increasing due to industrialization and industrial development, and in particular, the dependence of energy resources existing on the seabed is increasing. In this way, as mining and dependence on submarine energy resources increase, the amount of drilling work of the rig is increasing. Drill rigs use several methods for transferring pipe members from a pipe rack adjacent to the drilling bottom to a small hole or borehole in the drilling bottom to connect to a pipe or tubular string previously conveyed. The term pipe refers to all types of drilling pipes, drill collars, casings, liners, bottom hole assemblies (BHA) of any other type known in the art. Includes coffins. In the case of such a pipe, as it is connected to the length and drilling equipment, precise connection work must be made when connecting with multiple pipes or drilling equipment to prevent large-scale accidents.

When connecting the pipe and the fixing means, it is in the order of mounting it on a plurality of cylindrical jigs formed on the upper part of the pad using a crane, and then assembling them, but this process requires unnecessary manipulation of various equipment and the use of a plurality of circular jigs. Accordingly, the size is large and the operation speed is slow, resulting in a decrease in work efficiency, and when a problem occurs with a single device and equipment, the time to restart is lengthened, resulting in a problem of lower product productivity.

A preparatory step of fixing the connecting means using hydraulic pressure to the bite of the jig member formed on the front of the rotating part;

A pipe transfer step of transferring a plurality of transfer members to an upper portion of the main body so as to transfer the pipes at regular intervals, a roller part provided on the transfer member, and transferring to a fixed connection means in the preparation stage using the transfer member;

When the pipe is transferred, the bottom of the pipe is seated on the lower jig with the first teeth formed on the upper part of the main body, and the upper jig with the second semicircular teeth is fixed downward due to the hydraulic cylinder rod on the top of the pipe. ;

It consists of a pipe connection step of fixing the pipe and the connection means by rotating the rotating member after the connection means fixed in the preparation step and the fixing means of the pipe are interviewed,

In addition, a first coupling hole and a second coupling hole are formed at regular intervals in the lower jig and the upper jig, so that the first toothed unit and the second toothed unit are selectively fixed to each coupling hole as a fixing means, and when the pipe is transferred A second pipe fixing step in which the bottom of the pipe is seated on the lower jig with the first toothed unit formed on the top of the main body, and the upper jig with the second toothed unit is fixed downward on the upper surface of the pipe by the hydraulic cylinder rod.

The present invention is an automated system from pipe transfer to pipe fixing and connection for efficient pipe transfer, and the effect of connecting pipes with a minimum number of personnel and minimizing the time required for assembly production, improving product productivity and reducing manufacturing cost It can be used in a narrow space by increasing the size of the device and minimizing the size of the equipment, and it has an advantageous effect on moving equipment and re-installing equipment.
