Description

Top Compensator Test Device < RTI ID = 0.0 >

The present invention relates to a top companter testing apparatus. More specifically, by using a stud bolt made of a standard product as a test piece for a test tool, it is possible to reduce manufacturing cost by separately preparing a specimen and further processing it, By providing a test jig capable of detachably coupling the stud bolts, it is possible to easily assemble the various stud bolts and to continuously use them without repeated replacement of the test jig And more particularly, to a top compensator test apparatus capable of performing a test operation more conveniently.

As the international phenomenon of industrialization and industry develops, the use of resources such as petroleum is gradually increasing, and thus the stable production and supply of oil is becoming a very important issue on a global scale.

For this reason, the development of the marginal field or deep-sea oil field, which had been neglected due to economic difficulties, has become economic in recent years. Therefore, along with the development of seabed mining technology, drilling rigs with drilling facilities suitable for the development of such oilfields have been developed.

Conventional subsea drilling has been mainly used for fixed platforms where drilling is performed at one point in the offshore area. Recently, a variety of drilling rigs such as a floating drilling facility capable of drilling at depths of 3,000 m or more and a drill ship having self- Has been developed and is being used for underwater drilling.

Various drilling equipment such as derrick system, riser, and drill pipe are installed in the drill ship to drill oil and gas existing under the sea floor. Such drill ship can be operated by sweeping and position by wind, wind, The smaller the change, the more stable the development of the well. In particular, even if the drill ship moves vertically due to the currents, wind direction, wind speed and waves during the drilling process, the position of the drill pipe drilling the bottom of the sea floor can be kept constant regardless of the position, A well compressor can be developed and a top compensator device is installed on the drill rig to correct the position change of the drill pipe.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a conceptual diagram schematically showing a layout structure of a general top compartment unit. FIG.

1, a drill floor 11, which is a drilling work space, is formed on a drill rig 10 such as a semi-rig, and on the upper part of the drill floor 11, (20) is installed. A top drive 40 is mounted on the top of the drill floor 11 to connect and operate a drill pipe 50. The top drive 40 is connected to a top compartment 30 So that the up-and-down motion of the hull can be compensated. A separate riser 60 is mounted on the outer periphery of the drill pipe 50. The drill pipe 50 is connected to the top drive 40,

The top compartment unit 30 includes a driving unit 32 mounted on the drill floor 11 and a crown block 31 connected to the driving unit 32 through a separate wire W. The crown block 31 Is configured to move up and down in accordance with a change in tension of the wire W by the driving unit 32. [ The driving unit 32 includes a driving motor (not shown) that can actively regulate the tension of the wire W by winding and unwinding the wire W and a driving motor (not shown) by which the tension of the wire W due to the up- And a hydraulic cylinder (not shown) that can compensate the pressure. The top drive 40 is supported in such a manner that it is suspended from the crown block 31 of the top compartment 30 through wires.

Therefore, even if vertical movement of the hull occurs due to wind or waves, the top drive 40 compensates for the up-and-down movement by the top compartment unit 30 to maintain a constant vertical height, The position of the drill pipe 50 connected to the top drive 40 can be kept constant, and thus the development of the submarine oil well can be performed more stably.

Of course, the top compensator 30 may be configured in various manners to maintain the top drive 40 at a predetermined position by compensating for up-and-down movement of the hull in addition to the above-described method.

Such a top compander 30 is subjected to various performance test procedures through trial operation before being put into the actual drilling site and operated, and during various performance tests, a tensile performance test is performed on the topcompensator 30 .

A general tensile force performance test according to the prior art is performed using a separate specimen T as shown in FIG. The wire W was connected and the top compartment 30 was operated to apply tensile force to the specimen T. [

At this time, as shown in FIG. 2, the specimen T is formed with an intermediate cut portion T2 at an intermediate section so that it can be cut when a tensile load of a certain strength or more is applied, W are connected to each other. This type of specimen T must be precisely fabricated in a precise form for its dimensions and materials for precise performance testing and additional hooks T1 must be additionally machined to allow connection with the top compartment 30 The test cost and the work process are increased due to the increase of the cost of manufacturing the specimen, and the maintenance work of the specimen is also inconvenient because various kinds of specimen must be manufactured and managed according to the tensile strength.
