Description

Technical Field

[0001] This utility model relates to the technical field of fracturing tube assembly, specifically a high-efficiency heat dissipation fracturing tube assembly for liquid oxygen fracturing. Background Technology

[0002] A fracturing pipe is a specialized piece of equipment used in the oil and gas extraction industry. It is typically used in the hydraulic fracturing process of oil and gas wells and plays an important role in fracturing operations. It helps inject fracturing fluid into underground oil and gas reservoirs to create fractures, thereby improving the flow and production of oil and gas. Liquid oxygen fracturing pipes are one type, which use liquid oxygen as a power source.

[0003] During the injection of liquid oxygen into the fracturing tube and its use, high-pressure oxygen flows inside the fracturing tube. Under high pressure, the fracturing tube as a whole generates high temperature, which changes the physical properties of the fracturing tube, causing changes in its pressure resistance and thus affecting its service life. To address this, we propose a liquid oxygen fracturing tube high-efficiency heat dissipation fracturing tube assembly. Utility Model Content

[0004] To address the shortcomings of existing high-efficiency heat-dissipating fracturing tube assemblies for liquid oxygen fracturing, this invention provides a high-efficiency heat-dissipating fracturing tube assembly for liquid oxygen fracturing. The assembly includes a heat-dissipating sleeve fitted over the fracturing tube body, with ventilation holes on the outside of the outer sleeve. During use, the fracturing tube drives high-pressure gas to be ejected through the energy release head. The ejected gas circulates outside the oxygen inlet head through the ventilation holes, achieving high-efficiency heat dissipation for the entire heat-dissipating sleeve and solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a high-efficiency heat-dissipating fracturing tube assembly for liquid oxygen fracturing, comprising a fracturing tube body, a first limiting sleeve and a second limiting sleeve respectively installed on both sides of the fracturing tube body, an energy venting head installed inside the first limiting sleeve, an oxygen inlet head installed inside the second limiting sleeve, and fastening bolts installed on the internal threads of the second limiting sleeve and the oxygen inlet head, a heat dissipation sleeve movably sleeved on the outside of the fracturing tube body, an outer jacket fixed at equal intervals on the outside of the heat dissipation sleeve, ventilation holes opened on both sides of the outer jacket, a first ventilation pipe outer sleeve movably sleeved on the outside of the second limiting sleeve and the outer jacket, and a second ventilation pipe outer sleeve sleeved on the outside of the first limiting sleeve and the outer jacket.

[0006] Preferably, the inside of the rupture tube body is provided with a sliding groove, and the inner side of the heat dissipation sleeve is fixed with a limiting pin, which is movably sleeved inside the sliding groove.

[0007] Preferably, the first limiting sleeve and the second limiting sleeve are respectively installed on both sides of the rupture tube body, and the first limiting sleeve and the second limiting sleeve are sleeved on the outside of the heat dissipation sleeve and the outer jacket.

[0008] Preferably, an inner sleeve is installed inside the fracturing tube body, and an air outlet is provided inside the energy release head.

[0009] Preferably, a ventilation device is installed inside the first ventilation duct jacket, the ventilation device is installed outside the ventilation hole, and a cavity is formed between the heat dissipation sleeve and the outer jacket.

[0010] Preferably, a heat sink plate is fitted onto the outside of the heat sink sleeve, the heat sink plates are arranged at equal intervals on the outside of the heat sink sleeve, and the outside of the outer sleeve is circular.

[0011] Preferably, the first ventilation duct sleeve and the second ventilation duct sleeve are fixed to the outside of the outer sleeve by bolts, and the hole opened inside the second ventilation duct sleeve is aligned with the ventilation hole opened on one side of the outer sleeve.

[0012] Compared with existing high-efficiency heat dissipation fracturing tube assemblies for liquid oxygen fracturing, this invention has the following advantages:

[0013] 1. This high-efficiency heat-dissipating fracturing tube assembly for liquid oxygen fracturing, after being installed on the outside of the fracturing tube body by a heat dissipation sleeve, effectively absorbs heat. During the injection of liquid oxygen, a first ventilation pipe outer sleeve and a second ventilation pipe outer sleeve are respectively installed on the outside of the outer jacket on both sides. The ventilation device is activated to improve heat dissipation performance by increasing gas flow. When the equipment is in use, the first and second ventilation pipe outer sleeves are removed, and after the high-pressure gas is ejected through the energy release head, the leaked gas is input through the ventilation hole opened at one end of the outer jacket and output through another set of ventilation holes, which can also achieve the effect of high-efficiency heat dissipation.

[0014] 2. The high-efficiency heat-dissipating fracturing tube assembly for liquid oxygen fracturing has a heat dissipation sleeve that is snapped into the inside of the fracturing tube body by a limiting pin. At the same time, the first limiting sleeve and the second limiting sleeve are rotated to limit the position of the heat dissipation sleeve, ensuring the stability of the heat dissipation sleeve when the position is limited, and ensuring the convenience of equipment installation and disassembly.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A high-efficiency heat-dissipating fracturing tube assembly for liquid oxygen fracturing includes a fracturing tube body 1. A first limiting sleeve 2 and a second limiting sleeve 3 are respectively installed on both sides of the fracturing tube body 1. The first limiting sleeve 2 and the second limiting sleeve 3 are installed on both sides of the fracturing tube body 1, thus limiting the position of a heat dissipation sleeve 6. An energy release head 4 is installed inside the first limiting sleeve 2, and an oxygen inlet head 5 is installed inside the second limiting sleeve 3. The energy release head 4 and the oxygen inlet head 5 respectively drive high-pressure gas output and hydraulic injection into the interior of the fracturing tube body 1. Fastening bolts 7 are threaded inside the second limiting sleeve 3 and the oxygen inlet head 5. A heat dissipation sleeve 6 is movably sleeved on the outside of the fracturing tube body 1. The heat sink 9 installed on the outside of the heat sink 6 effectively absorbs the generated heat. The heat sink 6 is fixed with an outer jacket 10 at equal intervals. Ventilation holes 11 are opened on both sides of the outer jacket 10, which promotes gas circulation. The second limiting sleeve 3 and the outer jacket 10 are movably sleeved with a first ventilation pipe outer sleeve 12. The first limiting sleeve 2 and the outer jacket 10 are sleeved with a second ventilation pipe outer sleeve 14. The first ventilation pipe outer sleeve 12 and the second ventilation pipe outer sleeve 14 are sleeved on the outside of the outer jacket 10. The first ventilation pipe outer sleeve 12 and the second ventilation pipe outer sleeve 14 help improve gas circulation. At the same time, the first ventilation pipe outer sleeve 12 and the second ventilation pipe outer sleeve 14 can be disassembled and replaced when the equipment is in use.

[0023] Please see Figure 4The inside of the rupture tube body 1 is provided with a sliding groove, and the inner side of the heat dissipation sleeve 6 is fixed with a limiting pin 8. The limiting pin 8 is movably sleeved inside the sliding groove. By providing a sliding groove on the outside of the rupture tube body 1 and having the limiting pin 8 fixed on the inner side of the heat dissipation sleeve 6 slide into the installation sliding groove, the heat dissipation sleeve 6 is ensured to maintain stability when installed on the outside of the rupture tube body 1, and can be disassembled and replaced in the future by sliding in.

[0024] Please see Figure 2 The first limiting sleeve 2 and the second limiting sleeve 3 are respectively installed on both sides of the fracture tube body 1, and the first limiting sleeve 2 and the second limiting sleeve 3 are sleeved on the outside of the heat dissipation sleeve 6 and the outer clamp 10. By installing the first limiting sleeve 2 and the second limiting sleeve 3 on both sides of the fracture tube body 1, the first limiting sleeve 2 and the second limiting sleeve 3 limit the position of the heat dissipation sleeve 6 inside the fracture tube body 1, so as to avoid the problem of loosening of the heat dissipation sleeve 6 during installation.

[0025] Please see Figure 3 The inside of the fracturing pipe body 1 is equipped with an inner sleeve, and the inside of the energy release head 4 is provided with an air outlet. Liquid oxygen is injected into the inner sleeve through the inner sleeve installed inside the fracturing pipe body 1 and the oxygen supply head 5. When the equipment needs to be excavated, the liquid oxygen output is controlled, and the liquid oxygen forms a high-pressure gas. The high-pressure gas is ejected through the energy release head 4, and under the action of high pressure, cracks are formed in the ground.

[0026] Please see Figure 5 A ventilation device 13 is installed inside the first ventilation pipe outer sleeve 12. The ventilation device 13 is installed outside the ventilation hole 11. A cavity is formed between the heat dissipation sleeve 6 and the outer jacket 10. During the process of injecting hydraulic pressure into the fracturing tube body 1, high pressure is generated. The pressure directly causes the temperature of the inner wall of the fracturing tube body 1 to rise, which affects the service life of the equipment. Therefore, the first ventilation pipe outer sleeve 12 is sleeved and installed outside the second limiting sleeve 3 and the outer jacket 10. When the ventilation device 13 is started, the ventilation device 13 drives the gas to circulate. After the gas circulates inside the heat dissipation sleeve 6 and the outer jacket 10, the fracturing tube body 1 can be cooled down quickly.

[0027] Please see Figure 4 A heat dissipation plate 9 is installed on the outside of the heat dissipation sleeve 6. The heat dissipation plates 9 are arranged at equal intervals on the outside of the heat dissipation sleeve 6. The outside of the outer sleeve 10 is circular. The heat dissipation plate 9 is fixed on the outside of the heat dissipation sleeve 6. The heat dissipation plate 9 effectively absorbs the heat generated inside the fracture tube body 1, achieving a high-efficiency heat dissipation effect.

[0028] Please see Figure 1The first ventilation pipe sleeve 12 and the second ventilation pipe sleeve 14 are fixed to the outside of the outer jacket 10 by bolts. The hole opened inside the second ventilation pipe sleeve 14 is aligned with the ventilation hole 11 opened on one side of the outer jacket 10. The first ventilation pipe sleeve 12 and the second ventilation pipe sleeve 14 are fixed to the outside of the outer jacket 10 by threads. That is, the first ventilation pipe sleeve 12 and the second ventilation pipe sleeve 14 can be disassembled during use. When injecting liquid oxygen, the heat dissipation performance of the equipment can be improved by the assistance of the first ventilation pipe sleeve 12 and the second ventilation pipe sleeve 14. When the equipment is in use, ventilation holes 11 are opened on both sides of the outer jacket 10. The gas can be absorbed through the ventilation holes 11 to facilitate the flow of gas and also make the equipment play a heat dissipation role during use.

[0029] Working principle: During use, a sliding groove is provided on the outside of the fracturing tube body 1, through which the heat dissipation sleeve 6 is movably sleeved on the outside of the fracturing tube body 1 via a limiting pin 8. Simultaneously, the first limiting sleeve 2 and the second limiting sleeve 3 are installed on both sides of the fracturing tube body 1 to limit the position of the heat dissipation sleeve 6. An energy release head 4 and an oxygen inlet head 5 are installed on both sides of the first limiting sleeve 2 and the second limiting sleeve 3. Liquid oxygen is injected into the interior of the fracturing tube body 1 through the oxygen inlet head 5. During the injection of liquid oxygen, the increased pressure causes high temperatures to form on the inner wall of the fracturing tube body 1. Therefore, during the first ventilation... The outer sleeve 12 and the second ventilation sleeve 14 are fitted onto the outside of the outer jacket 10. When the ventilation device 13 is activated, the ventilation device 13 drives the gas flow, achieving the effect of high-speed heat dissipation of the entire rupture tube body 1. The first ventilation sleeve 12 and the second ventilation sleeve 14 can be disassembled. After disassembly, the equipment is controlled for use. Heat is absorbed by the heat sink 9. At the same time, when liquid oxygen is output, it drives the gas flow and outputs through the ventilation hole 11 opened at one end of the outer jacket 10, and also through another set of ventilation holes 11, further improving the efficient heat dissipation effect of the equipment.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
