Description

Technical Field

[0001] This utility model relates to the field of oil and gas recovery technology, specifically to an antifreeze oil and gas recovery pipeline structure for northern regions. Background Technology

[0002] In northern regions, winters are often accompanied by extremely cold weather, with temperatures in some areas frequently plummeting to tens of degrees below zero Celsius. Such extreme cold poses a significant challenge to the structure of conventional oil and gas recovery pipelines. Current pipeline designs do not adequately account for such harsh low-temperature environments, resulting in a lack of reliable antifreeze measures.

[0003] In low-temperature environments, the oil and gas within pipelines primarily consist of various easily condensable hydrocarbons. As temperatures continue to drop, the molecular activity of these hydrocarbons decreases significantly, increasing their intermolecular forces and making them highly prone to condensation. Once condensed, the oil and gas form solid or semi-solid deposits inside the pipeline, gradually accumulating and eventually causing blockages. Pipeline blockages not only prevent the normal flow of oil and gas, halting recovery operations, but also trigger a series of chain reactions, such as abnormally high equipment pressure, threatening the safety of the entire recovery system. Therefore, a freeze-resistant oil and gas recovery pipeline structure for northern regions is urgently needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide an antifreeze oil and gas recovery pipeline structure for northern regions, in order to solve the problem mentioned in the background art that the existing pipeline structure does not fully consider such a harsh low-temperature environment in its design, resulting in a lack of reliable antifreeze measures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a freeze-resistant oil and gas recovery pipeline structure for northern regions, comprising a pipeline body, a functional box, and a heating pipe. The functional box contains a rotating chamber and a movable chamber. A reciprocating screw is rotatably mounted in the rotating chamber. A power mechanism connected to the reciprocating screw is located outside the functional box. A piston plate is located in the movable chamber and is connected to the reciprocating screw via a connecting mechanism. A screw and a vertical heating rod are rotatably mounted in the movable chamber. The piston plate is connected to the screw via a connecting mechanism. Multiple horizontal heating rods are mounted on the vertical heating rod, and a connecting line extending to the outside of the functional box is provided on the vertical heating rod. The functional box contains a recovery pipe connected to the heating pipe and a discharge pipe.

[0006] Preferably, the power mechanism includes a drive motor mounted on the function box, and the end of the output shaft of the drive motor is fixedly connected to the end of the reciprocating lead screw.

[0007] Preferably, the connecting mechanism includes a connecting frame threaded onto a reciprocating lead screw, and the end of the connecting frame is fixedly connected to a piston plate.

[0008] Preferably, the connecting mechanism includes a connecting rod mounted on a piston plate, and a threaded connecting block is installed at the end of the connecting rod, the threaded connecting block being threadedly connected to the screw.

[0009] Preferably, both the recovery pipe and the discharge pipe are equipped with valves, and both valves are one-way valves.

[0010] Preferably, the piston plate is slidably and sealed within the active chamber, and the connecting line is rotatably connected to the vertical heating rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By coordinating the heating of hot water within the heating pipes and the heating components within the functional box, sufficient heat can be continuously provided to the oil and gas within the pipeline body, effectively preventing condensation of oil and gas in low-temperature environments and greatly improving the adaptability and reliability of the oil and gas recovery pipeline in cold northern regions. Moreover, the hot water circulation heating mode further enhances the heating effect and energy utilization efficiency.

[0013] 2. A series of mechanical movements driven by the power mechanism, such as the reciprocating motion of the piston plate and the rotational motion of the screw, can indirectly affect the hot water circulation system, ensuring stable heating of hot water, thereby adapting to the heating needs of oil and gas in the pipeline body under different working conditions and improving the overall performance of the oil and gas recovery system.

[0014] 3. The one-way valves in the recovery and discharge pipes effectively prevent hot water backflow, ensure smooth hot water circulation, and guarantee that hot water can continuously and efficiently heat the pipeline body, reducing energy waste and improving system stability.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides an antifreeze oil and gas recovery pipeline structure for northern regions.

[0022] Pipeline body 1: As the main channel for oil and gas transmission, it is responsible for transporting oil and gas from the source to the recovery and processing equipment.

[0023] Functional box 2: Its internal structure is complex and precise, divided into a rotating chamber 7 and a movable chamber 8. The rotating chamber 7 is used to install the reciprocating lead screw 9, providing a spatial basis for subsequent mechanical transmission; the movable chamber 8 houses key components such as the piston plate 11, screw 12, vertical heating rod 13, and horizontal heating rod 14, and is the core area for realizing multiple functions.

[0024] Heating pipe 3: Hot water circulates inside, providing a suitable temperature for the oil and gas in the main pipe 1 through heat transfer, effectively preventing problems such as condensation and blockage of oil and gas due to low temperature. Furthermore, it, together with the recovery pipe 4 and the discharge pipe 6, forms a hot water circulation system.

[0025] The power mechanism consists of a drive motor 5 mounted on the function box 2. The output shaft of the drive motor 5 is fixedly connected to the end of the reciprocating screw 9. When the drive motor 5 starts, it can provide stable rotational power to the reciprocating screw 9, thereby driving the related mechanical components to operate.

[0026] The connecting mechanism includes a connecting bracket 10 threaded onto the reciprocating screw 9, with its end fixedly connected to the piston plate 11. The function of this mechanism is to convert the rotational motion of the reciprocating screw 9 into the linear reciprocating motion of the piston plate 11 within the moving chamber 8.

[0027] The connecting mechanism consists of a connecting rod 16 mounted on the piston plate 11 and a threaded connecting block 17 installed at the end of the connecting rod 16. The threaded connecting block 17 is threadedly connected to the screw 12. Through this connecting mechanism, the linear motion of the piston plate 11 can drive the screw 12 to rotate.

[0028] The recovery pipe 4 and the discharge pipe 6: The recovery pipe 4 introduces cold water from the heating pipe 3 into the active chamber 8, while the discharge pipe 6 returns the hot water from the active chamber 8, heated by the heating element, to the heating pipe 3, thus achieving hot water circulation within the system. Both pipes are tightly connected to the heating pipe 3 to ensure smooth hot water circulation. Both the recovery pipe 4 and the discharge pipe 6 are equipped with valves 18, and both valves 18 are one-way valves, effectively preventing hot water backflow and ensuring that the hot water circulates in the predetermined direction.

[0029] Other components: A screw 12 and a vertical heating rod 13 are rotatably mounted inside the active chamber 8. Multiple horizontal heating rods 14 are installed on the vertical heating rod 13. These heating rods together constitute the heating assembly, providing heat to the hot water. A connecting line 15 extending from the vertical heating rod 13 to the outside of the functional box 2 is provided for connecting to an external power source to power the heating assembly. The piston plate 11 is slidably and sealingly disposed within the active chamber 8 to ensure the airtightness of the interior of the active chamber 8; the connecting line 15 is rotatably connected to the vertical heating rod 13, so that the connecting line 15 is not subjected to excessive torque when the vertical heating rod 13 rotates.

[0030] Working principle: When the drive motor 5 starts, its output shaft drives the reciprocating screw 9 to rotate. Since the connecting frame 10 is threaded onto the reciprocating screw 9 and is fixedly connected to the piston plate 11, the rotation of the reciprocating screw 9 causes the piston plate 11 to perform linear reciprocating motion within the movable chamber 8. The piston plate 11 is connected to the screw 12 via the connecting rod 16 and the threaded connecting block 17, and the linear motion of the piston plate 11 is converted into the rotational motion of the screw 12. At the same time, an external power supply provides power to the vertical heating rod 13 and the horizontal heating rod 14 through the connecting wire 15.

[0031] Cooler hot water flows from heating pipe 3 into active chamber 8 via recovery pipe 4. Inside active chamber 8, the heating element heats the incoming hot water, raising its temperature. The heated hot water then flows back to heating pipe 3 via discharge pipe 6, completing one cycle. The hot water in heating pipe 3 continuously transfers heat to the pipeline body 1 through heat conduction, heating the oil and gas within the pipeline body 1 and preventing condensation due to low temperatures. The rotational movement of the vertical heating rod 13 and the horizontal heating rod 14 ensures more uniform mixing of the hot water in active chamber 8, optimizing the heating effect of the heating element and thus ensuring the stability of oil and gas heating within the pipeline body 1. The continuously heated oil and gas maintains a suitable temperature within the pipeline body 1 and is smoothly transported from the source to the recycling and processing equipment.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
