Description

Technical Field

[0001] The utility model relates to the technical field of casing protection tools, in particular to a hydraulic casing protection tool. Background Art

[0002] The hydraulic casing protection tool is a kind of equipment used in oil and gas drilling. It protects and supports the casing through the hydraulic principle. Its main function is to apply hydraulic pressure to the outside of the casing during drilling operations to ensure that the casing is not affected by external pressure and formation deformation and does not collapse or deform, thereby ensuring the safety and smooth progress of the drilling operation. The use of hydraulic casing protection tools can effectively reduce the occurrence of drilling accidents and improve operating efficiency and the service life of the casing.

[0003] Hydraulic casing protection tools are mainly divided into hydraulic collapse preventers and hydraulic pipe strings. The hydraulic collapse preventers form a stable hydraulic film on the outside of the casing through the internal hydraulic system to resist the squeezing force of the formation and prevent the casing from collapsing. The hydraulic pipe string uses hydraulic action to form a supporting force outside the casing to support the casing to prevent it from being squeezed and deformed in complex environments such as high temperature and high pressure, thereby ensuring the safety of drilling operations.

[0004] However, the existing hydraulic casing protection tools have low work efficiency due to the long installation and disassembly process, and some hydraulic casing protection tools may only be suitable for pipelines of specific types or specifications and cannot meet the protection needs of all pipelines, resulting in the need to use multiple types of protection tools in some cases, increasing the management and cost burden. Therefore, a hydraulic casing protection tool is proposed. Utility Model Content

[0025] Specifically, the hydraulic rod 4 drives the rotating ring 6 connected to the articulated seat 5 to rotate, and then under the constraint of the limit groove 7, the fixed roller 13 guides the sliding block 8 to slide smoothly inside the groove 12. This design ensures that the fixed cylinder 1 can flexibly adapt to a variety of pipes with different diameters, thereby ensuring the safety of the transportation process. The connecting block 2 9 is connected to the anti-sliding block 10 and is rotatably installed inside the sliding block 8, so that under appropriate pressure, the anti-sliding block 10 can fit tightly to the outer wall of the pipeline, simplifying the installation process of the protective sleeve and improving its convenience of maintenance, thereby effectively enhancing the practicality and operability of the tool.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The adjusting component includes a fixed card block 20, the outer wall of the fixed card block 20 is fixedly connected to the outer wall of the sliding cylinder 2, a spiral groove 14 is opened inside the fixed cylinder 1, the outer wall of the fixed card block 20 is slidably connected to the inner wall of the spiral groove 14, the fixed cylinder 1 is slidably connected to the sliding cylinder 2 19 inside the fixed cylinder 1, the buffer layer 15 is fixedly connected inside the fixed cylinder 1, the outer wall of the sliding cylinder 2 is threadedly connected to a cover 16, the inner part of the cover 16 is fixedly connected to a sealing layer 17, the outer wall of the sealing layer 17 abuts against the upper surface of the sliding cylinder 2, the inner part of the cover 16 is fixedly connected to a silicone layer 18, a groove 12 is opened inside the fixed ring 11, the outer wall of the sliding block 8 is slidably connected to the inner wall of the groove 12, the outer wall of the fixed roller 13 is slidably connected to the inner wall of the limiting groove 7, and the upper surface of the rotating ring 6 is rotatably connected to the lower surface of the fixed ring 11.

[0027] Specifically, the fixed cylinder 1, the sliding cylinder 1 2 and the sliding cylinder 2 19 are installed on the pipeline, and then the sliding cylinder 1 2 and the sliding cylinder 2 19 are rotated by using a tool, and the fixed block 20 connected to the sliding cylinder 1 2 and the sliding cylinder 2 19 will slide along the spiral groove 14 inside the fixed cylinder 1, so as to realize the flexible adjustment of the length of the protective sleeve. The interiors of the fixed cylinder 1, the sliding cylinder 1 2 and the sliding cylinder 2 19 are all equipped with the same fixing mechanism as that in the fixed cylinder 1, ensuring that the protective sleeve as a whole can be firmly fixed on the outer wall of the pipeline to ensure its stability and safety.

[0028] Working principle: When it is necessary to use the hydraulic casing protection tool, first install the fixed cylinder 1, the sliding cylinder 1 2 and the sliding cylinder 2 19 on the pipeline, and use the tool to rotate the sliding cylinder 1 2 and the sliding cylinder 2 19 so that the fixed clamping block 20 connected with the sliding cylinder 1 2 and the sliding cylinder 2 19 slides inside the spiral groove 14 inside the fixed cylinder 1, so as to achieve the effect of flexibly adjusting the length of the protective casing. The fixed cylinder 1, the sliding cylinder 1 2 and the sliding cylinder 2 19 are all provided with fixing mechanisms, which can ensure that the protective casing as a whole can be firmly fixed to the outer wall of the pipeline. After adjusting the length, the hydraulic rod 4 drives the rotating ring 6 connected to the articulated seat 5 to rotate, so that the fixed roller 13 makes the sliding roller 13 slide under the restriction of the limit groove 7. The movable block 8 slides inside the groove 12, so that the fixed cylinder 1 can flexibly adapt to pipes of different diameters to ensure safe transportation. The connecting block 2 9 connected to the anti-sliding block 10 is rotatably connected inside the sliding block 8, and can be tightly attached to the outer wall of the pipe under a certain pressure, so as to achieve the effect of easy installation of the protective sleeve, and also facilitate the maintenance of the protective sleeve and improve the practicality of the tool. The closing cover 16 arranged on the sliding cylinder 2 can be replaced according to the diameter of the pipe. The sealing layer 17 and the silicone layer 18 can prevent the outer wall of the pipe from being corroded, so as to achieve the effect of increasing the service life of the pipe. The inner wall of the protective sleeve is provided with a buffer layer 15, which can effectively buffer the external pressure and can effectively protect the life of the pipe.
