Description

Technical Field

[0001] This utility model relates to an oil production device, and more specifically, to an adjustable coiled tubing injection head assembly. Background Technology

[0002] When connecting the injection head to the wellhead, a crane and manual labor are required for installation. For example... Figure 5 As shown, four steel wire ropes Q are installed at the top of frame P. A crane lifts frame P through lifting point S. During the lifting process, the angle of frame P is difficult to control, making coordination challenging. If the crane swings too much, it can easily cause personnel to fall or damage to the wellhead equipment and facilities. In addition, it is difficult to ensure that the steel wire ropes are evenly stressed during the lifting process, which may cause a single strand of the steel wire rope to break, seriously affecting production safety.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention provides an adjustable coiled tubing injection head assembly. During the injection head docking process, the operator controls the extension and retraction of the hydraulic unit, thereby precisely controlling the suspension angle of the suspension frame, completely eliminating the need for manual union docking. Simultaneously, the crane no longer needs to swing and adjust the injection head when lifting it to the wellhead, making operation convenient. Since the operator can perform remote ground operation, the risk of hand pinching is completely eliminated, reducing manual labor intensity and improving safety. Furthermore, due to the combined structure of the lower arm, upper arm, and lifting support, the strength is far greater than that of ordinary wire ropes, eliminating the need for personnel to climb to inspect the wire rope ends for broken strands, further reducing worker labor intensity and improving the safety of the working environment.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figures 1 to 4 As shown, the adjustable continuous tubing injection head assembly includes a suspension frame 1 for placing the injection head. The top of the suspension frame 1 is provided with a first crossbar 11 and a second crossbar 12. Both ends of the first crossbar 11 are provided with a rotatable hydraulic unit 2. Both ends of the second crossbar 12 are provided with a rotatable lower arm 3. The hydraulic unit 2 includes a hydraulic cylinder 21 and a hydraulic rod 211. The end of the hydraulic rod 211 is provided with a rod connector 22, which is hinged to the lower arm 3. The top of the lower arm 3 is provided with a rotatable upper arm 4, and a suspension bracket 5 is provided between the tops of the upper arms 4.

[0022] It should be noted that the top of the lifting bracket 5 is equipped with a lifting point K for crane lifting. In addition, the upper arm 4 is welded to the lifting bracket 5.

[0023] The first crossbar 11 has a first crossbar hole 111 at both ends. The bottom of the hydraulic cylinder body 21 has a cylinder body connecting flange 23, and the cylinder body connecting flange 23 has a flange hole 231. The flange hole 231 is connected to the first crossbar hole 111 by a connecting pin 232. The second crossbar 12 has a rotating groove 13 at both ends, and the side wall of the rotating groove 13 has a rotating groove hole 131. The lower arm 3 includes a long strip-shaped lower arm body 31. The top is provided with an upper arm connecting groove 32, and the side wall of the upper arm connecting groove 32 is provided with a through upper arm connecting groove hole 33. The middle part of the lower arm body 31 is provided with a hinge hole 311, and the lower part of the lower arm body 31 is provided with a lower arm hole 34. The lower arm hole 34 is engaged with the rotating groove hole 131, and the hinge hole 311 is engaged with the rod body connector 22. The bottom of the upper arm 4 is provided with an upper arm hole 41, and the upper arm hole 41 is connected to the upper arm connecting groove hole 33 by a connecting pin 6.

[0024] The working principle of this adjustable coiled tubing injection head assembly is explained below.

[0025] like Figure 1 As shown, the injection head ( Figure 1 (Not shown) is fixed inside the suspension frame 1, and the lifting bracket 5 is lifted directly by a crane.

[0026] During the docking of the injection head, the operator controls the extension and retraction of the hydraulic unit 2, thereby precisely controlling the suspension angle of the suspension frame 1, eliminating the need for manual docking. Simultaneously, the crane no longer needs to swing and adjust the injection head when lifting it to the wellhead, making operation convenient.

[0027] Because operators can perform remote ground operations, the risk of fingers being pinched is completely eliminated, manual labor intensity is reduced, and safety is improved.

[0028] In addition, due to the combined structure of the lower arm 3, upper arm 4 and lifting bracket 5, the strength is much higher than that of ordinary wire ropes. There is no need for personnel to climb up to check whether there are broken strands at the end of the wire rope, which further reduces the labor intensity of workers and improves the safety of the working environment.

[0029] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
