Description

Technical Field

[0001] This utility model relates to the field of offshore oil and gas field development technology, and in particular to a tool for quickly disassembling casing sheath wire. Background Technology

[0002] Offshore oil and gas field development currently employs a rolling development model due to high exploration and development costs. For drilling and workover operations on production platforms at sea, there is often a shortage of space for placing tubing and casing, necessitating frequent transfers between the work vessel and the platform. Because the time interval between tripping out of the drill string and running casing is short, the placement, thread washing, gauging, and measurement of casing must be carried out quickly, efficiently, and systematically. Among these tasks, casing wire removal is the most time-consuming and labor-intensive. Currently, traditional casing wire removal is entirely manual or involves multiple people using tools such as pipe wrenches, F-wrenches, pry bars, and hammers. This method is inefficient, affects the progress of operations, and poses a potential safety risk of injury due to poor coordination. Utility Model Content

[0017] The present patent application will be further described below with reference to the embodiments.

[0018] like Figure 1 As shown, a tool for quickly removing sleeve protectors includes a central screw 1, an upper end cap 2, a connecting bolt 3, an ear plate 4, a reinforcing rib 5, a base 6, and a toothed plate 7.

[0019] The base 6 is a frustum-shaped structure. The center of the base 6 is welded and fixed to the central screw 1. The circumferential surface of the frustum of the base 6 can contact the ear plate 4 more closely, providing stable and uniform force support for the ear plate 4.

[0020] An upper end cap 2 is fitted onto the central screw 1. Specifically, a central hole is formed in the center of the upper end cap 2, and a thread is formed inside the central hole. The central screw 1 passes through the central hole, and the external thread of the central screw 1 matches the internal thread of the central hole. By rotating the screw 1, the distance between the upper end cap 2 and the base 6 can be adjusted to match different sizes of sleeves and wires, thereby achieving the purpose of disassembling sleeves and wires of different sizes.

[0021] Several ear plates 4 are evenly connected to the edge of the upper end cover 2. Preferably, three ear plates 4 are connected to the upper end cover 2, and the included angle between two adjacent ear plates 4 is 120°. The following is a detailed description using the example of setting three ear plates 4. In this application, connecting ears are connected to the edge of the upper end cover 2, and connecting ears are also connected to the upper end of the ear plates 4. Connecting bolts 3 pass through two connecting ears, thereby connecting the ear plates 4 to the upper end cover 2.

[0022] The ear plate 4 includes an inner plate 41 and an outer plate 42. The upper end of the inner plate 41 is provided with a connecting ear for connecting with the upper end cover 2, and the lower end of the inner plate 41 is connected to the lower end of the outer plate 42. The inner plate 41 and the outer plate 42 are set at a certain angle, specifically, the included angle between the inner plate 41 and the outer plate 42 is less than 45°. In order to enhance the mechanical strength of the ear plate 4, a reinforcing rib 5 is also provided between the inner plate 41 and the outer plate 42, thereby improving the service life of the entire device. The inner plate 41 is bent inward (towards the base 6) by 20°, which makes it easier for the ear plate 4 to fit more closely to the circumferential surface of the frustum of the base 6 when the central screw 1 is rotated to adjust the distance between the upper end cover 2 and the base 6. A toothed plate 7 is also connected to the lower end of the ear plate 4, and uniform teeth are formed on the toothed plate 7. The ear plate 4 of this application has a 20° arc inward pressing. The three ear plates 4 are evenly distributed at 120° and applied to the surface of the sleeve wire. The end of the ear plate 4 has teeth. The teeth can bite the sleeve wire when they are in force. The whole tool can be integrated with the sleeve wire. While lifting and removing the wire, it can effectively prevent the plastic sleeve wire from being deformed or damaged.

[0023] This application also provides ear plate mounting holes 8 on each of the outer plates 42. The low elastic coefficient springs use the ear plate mounting holes 8 to adaptively and tightly support the three ear plates 4 against the base 6, preventing the ear plates 4 from wobbling in all directions, making it easy to quickly insert tools into the inner hole of the sleeve wire, and facilitating operation and retrieval.

[0024] The central screw 1 and connecting bolt 3 of this utility model use general-purpose accessories, while the upper end cover 2, ear plate 4, reinforcing rib 5, and base 6 are made of iron plate material, which is easy to process and can meet certain strength requirements. The materials used in this application are common materials in production and have the characteristics of being economical, safe, and highly practical.

[0025] The method of using this utility model is as follows:

[0026] (1) Insert the hand-held disassembly tool into the inside of the sleeve protector;

[0027] (2) Rotate the central screw 1 to adjust the distance between the upper end cover 2 and the base 6 to clamp the three ear plates 4. The ear plates 4 themselves have a 20° arc to press inward. The three ear plates 4 are evenly distributed at 120° and are pressed on the surface of the sleeve wire.

[0028] (3) Continue to adjust the distance between the upper end cap 2 and the base 6, continuously squeeze the sleeve wire and lift it up. The end of the ear plate 4 has teeth, and the teeth bite the sleeve wire under force. The entire tool and the sleeve wire form an integral unit.

[0029] (4) Use a pneumatic wrench or electric drill with a screw to continue rotating the sleeve wire to remove it. Since the direction of rotating to remove the wire is the same as the direction of tightening the ear plate 4, the disassembly process will only get tighter and tighter and will not loosen or come off.

[0030] (5) After removing the sleeve wire, rotate it in the opposite direction to uncoupling the tool and the wire.

[0031] This utility model of a quick-release casing wire protector tool can safely, conveniently, and efficiently disassemble casing wire protectors between 6" and 10" sizes, fully meeting the on-site operational needs of 9-5 / 8" and 7" casing models. It is comprehensive in function and highly adaptable, successfully solving the problems of high labor intensity and low work efficiency when disassembling casing wire protectors manually by one person or with multiple people using tools such as pipe wrenches, F-type wrenches, pry bars, and hammers during drilling and workover. It also addresses the significant safety risks of injuries caused by poor communication or coordination errors when multiple people are disassembling casing wire protectors together. This tool greatly reduces workload, lowers labor intensity and potential work injury risks, and improves work efficiency.

[0032] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
