[0027] As an automated tool for the make-up and break-out operations of drill pipes at the wellhead, the iron roughneck plays an important role in drilling operations, which can significantly improve the operation efficiency of tripping and reduce the labor intensity of the drill floor operators.

[0028] The existing iron roughneck test devices can only conduct make-up and break-out tests for conventional wellheads, and cannot simulate the mousehole working conditions of actual well connections and the mud spraying environment for testing.

[0029] The following will describe Figures 1 to 9 the iron roughneck test device of the present invention, which includes a test bench 1, a mousehole tooling 2 and a mud shielding device 3.

Through the setting of the inclined plate 2106, the first drill pipe 24 can be directly in an inclined state and connected to the second drill pipe 27 through the first well buckle 25 and the second well buckle 26, and then the iron roughneck 4 can be used for multiple experiments of screwing on and unscrewing. It is very convenient. The 5000 times of screwing on and unscrewing experiments of the iron roughneck 4 can be realized in one week, avoiding the need for several months or even half a year to complete the experiment of the iron roughneck 4 in the past, which saves a lot of time.

[0046] The beneficial effects of the above optional embodiments are as follows: Since the bottom ball 222 is provided at the bottom of the cylinder body 22, the yaw of the first drill pipe 24 can be realized by loosening the three first positioning screws 2104 on one side and tightening the three first positioning screws 2104 on the other side. By limiting the upper cylinder 221 of the cylinder body 22 at the upper end of the first positioning sleeve 2102, the ±6° yaw limit and docking contact of the cylinder body 22 are realized, and then the unscrewing test of the iron roughneck 4 under the condition that the first drill pipe 24 of the cylinder body 22 is inclined is realized, which is relatively convenient and fast.

[0056] The beneficial effects of the above optional embodiments are as follows: The convenience of cleaning when the device is not in use is increased by the setting of the slope 106.

[0057] Optionally, as Figure 1 and Figure 3 shown, the mud guard device 3 includes a mud guard frame 31 and a mud guard plate 32. The mud guard frame 31 is slidably connected to the side wall of the base 101, and the mud guard plate 32 is installed on the mud guard frame 31.

[0058] In the above optional embodiments, it should be noted that the mud guard frame 31 is a three-sided enclosed frame structure formed by sequentially connecting three frame plates. That is, one frame plate is in the middle, and one frame plate is connected to each side of the middle frame plate, and the two side frame plates are perpendicular to the middle frame plate. A mud guard plate 32 is connected to the outside of each frame plate by means of screwing, clamping, welding or the like.

[0059] The base 101 and the mud guard frame 31 can be slidably connected in the form of a slide rail and a slider.

[0060] The mud guard device 3 further includes a handle. A handle is provided on one side of a mud guard plate 32 facing away from the corresponding frame plate to improve the convenience of sliding the mud guard device 3 relative to the base 101.

[0064] The beneficial effects of the above optional embodiments are as follows: By the setting of the rollers 33, the mud guard device 3 can be moved to enable the iron roughneck 4 to conduct tests according to actual working conditions.

[0065] The working principle of this device is as follows: When a make-and-break test needs to be carried out on the iron roughneck, if a normal make-and-break test is to be carried out, first, adjust multiple first positioning screws 2104 to adjust the cylinder body 22 to a vertical state. Then, use the electric hoist 5 to insert the first drill pipe 24 through the sleeve lining 23 and then insert it on the cylinder body 22. Use the electric hoist 5 to hang the second drill pipe 27 directly above the first drill pipe 24. Then, after using the iron roughneck 4 to make up the first well connection 25 on the first drill pipe 24 and the second well connection 26 on the second drill pipe 27, adjust multiple first positioning screws 2104 according to actual needs to adjust the inclination angle of the cylinder body 22 until the angle required for the test is adjusted; thus, the make-and-break test of the iron roughneck 4 under various working conditions without mud is realized. When a make-and-break test under working conditions including mud is to be carried out, move the mud shielding device 3 to the outer periphery of the test bench 1, then drive the mud pump to work, and then adjust multiple first positioning screws 2104 according to actual needs to adjust the inclination angle of the cylinder body 22 until the angle required for the test is adjusted, thereby realizing the make-and-break test of the iron roughneck 4 under various working conditions with mud; When the first drill pipe 24 needs to be inserted to different depths for the make-and-break test of the iron roughneck 4, it only needs to rotate the first drill pipe 24 to the specified depth according to actual needs, which is convenient and fast after all.

[0066] Furthermore, this device enables the iron roughneck 4 to perform yaw fixation of the drill pipe for simulating the mousehole working conditions for testing, can also perform make-and-break tests at the wellhead, and can also perform simulated make-and-break tests under mud working conditions to fully simulate the feasibility verification of the iron roughneck under actual working conditions, improving the product competitiveness. In addition, when using this device for conventional tests, only the iron roughneck 4 needs to be operated, without complex associated peripheral equipment, which is convenient to control, has high professional test assessment efficiency, and is built according to the test requirements of the iron roughneck 4. There is no need to build a special derrick or drill a test well, and the input cost is low.
