Description

Technical Field

[0001] This utility model relates to the field of heavy oil extraction technology, specifically to a heavy oil collection mechanism and extraction device. Background Technology

[0002] Heavy oil reserves account for a large portion of global crude oil reserves, and their effective development is a world-class problem. According to the petroleum and natural gas industry standard SY / T 6169—1995 "Reservoir Classification", heavy oil is defined as crude oil with a viscosity greater than 50 mPa·s under formation conditions [1]. The formation of heavy oil is very complex, and the biggest difference between it and ordinary crude oil is the degree of biodegradation. The higher the degree of degradation, the easier it is to form heavy oil. In the 1960s, heavy oil extraction technology began to be applied to industrial production and entered a period of rapid development. The existing heavy oil extraction technology can generally be divided into two categories: "thermal extraction" and "cold extraction".

[0003] Heavy oil has extremely high viscosity and poor fluidity, remaining almost solid at room temperature. This makes its extraction extremely difficult, requiring high-powered and stable pumping equipment. Even after viscosity-reducing steps, existing heavy oil extraction equipment still faces challenges when entering the oil reservoir to extract the oil. The presence of residual gums, asphalt, and other impurities in the heavy oil makes it difficult for the extraction equipment's ports to penetrate deeply into the oil layer, and these substances easily clog the ports, thus reducing the efficiency and stability of the heavy oil extraction equipment. Utility Model Content

[0004] This invention addresses the problem that the ports of existing heavy oil extraction equipment are difficult to penetrate deep into the oil and are easily clogged by gums, asphalt, and impurities, thus reducing the working efficiency and stability of the equipment.

[0047] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0048] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0049] Example 1

[0050] Heavy oil extraction technology mainly utilizes methods such as introducing steam, chemical flooding agents, microwaves, CO2 injection, or the injection of native microorganisms, as well as combustion, to reduce the viscosity of heavy oil before extraction equipment can pump it out. However, existing heavy oil extraction equipment still faces challenges during the extraction process due to the large amount of residual gum, asphalt, and other impurities in the heavy oil. These factors make it difficult for the extraction equipment's ports to penetrate deep into the oil reservoir and easily cause blockages, thus reducing the efficiency and stability of the heavy oil extraction equipment.

[0051] To address the aforementioned problems in the prior art, this embodiment provides a heavy oil extraction mechanism for heavy oil extraction operations. This mechanism can adapt to the complex composition of heavy oil, reducing the difficulty of deep extraction and minimizing equipment clogging. Please refer to... Figures 1-8 The heavy oil collection mechanism mainly includes: an internal oil extraction pipe 500, a stirring assembly 600, and a crushing assembly 700, etc.

[0052] The internal oil extraction pipe 500 is used to connect to the suction pump on the pipeline transporting heavy oil, which transports the heavy oil extracted from downhole to the storage equipment. For example... Figure 2 , Figure 3As shown, the main body of the inner oil extraction pipe 500 is roughly cylindrical in shape and hollow inside. One end of the inner oil extraction pipe 500 is a second oil outlet 520, which is used to connect to the oil pipeline. The other end of the inner oil extraction pipe 500 is a second oil inlet 510. When the collection mechanism is working, the second oil inlet 510 needs to be inserted into the heavy oil for extraction. A filter cover 511 is provided on the second oil inlet 510 to prevent impurities from entering the oil pipeline and to keep the impurities within the crushing component 700 for crushing.

[0053] The stirring assembly 600 is used to stir the oil to reduce the resistance of the heavy oil around the collection mechanism, allowing the collection mechanism to penetrate deeper into the heavy oil for extraction. In this embodiment, the stirring assembly 600 mainly consists of a first pipe section 640 and a second pipe section 650. The first pipe section 640 is roughly cylindrical and is rotatably mounted on the outer wall of the inner oil extraction pipe 500 via bearings. A second gear 610 is also mounted on the outer wall of the first pipe section 640, located near the second oil outlet 520 of the inner oil extraction pipe 500, for use in conjunction with an external drive mechanism for transmission. The second pipe section 650 is also roughly cylindrical, and its axial cross-sectional area is larger than that of the first pipe section 640, for accommodating the crushing assembly 700. A spiral stirring element 620 is provided on the outer wall of the second pipe section 650, which can agitate the surrounding heavy oil when the stirring assembly 600 rotates, reducing its resistance. Meanwhile, a drill bit 652 is installed at the end of the second pipe section 650 away from the first pipe section 640. When the stirring assembly 600 rotates, it also drives the drill bit 652 to rotate, thereby clearing and unblocking the heavy oil in front of the moving direction of the collection mechanism during its deep penetration. Furthermore, four third oil inlets 654 are provided at the end of the second pipe section 650 away from the first pipe section 640, and around the drill bit 652, allowing heavy oil to enter the interior of the second pipe section 650. Additionally, a third gear 630 is installed inside the end of the second pipe section 650 connected to the first pipe section 640. The third gear 630 is used for transmission between the stirring assembly 600 and the crushing assembly 700.

[0054] The crushing assembly 700 is used to process solid or semi-solid impurities in heavy oil, breaking them down to prevent clogging of the collection mechanism and oil pipelines. The crushing assembly 700 mainly consists of a housing 730 and crushing elements rotatably mounted on the housing 730. The housing 730 has an opening at the top and is fitted over the lower end of the inner oil extraction pipe 500. A central chamber 734 is located in the middle of the housing 730 to accommodate one end of the second oil inlet 510 of the inner oil extraction pipe 500. An annular chamber 735 surrounds the central chamber 734, and a first auxiliary chamber 736 and a second auxiliary chamber 737 are located on opposite sides inside the annular chamber 735. The first auxiliary chamber 736 is generally cylindrical. A first oil inlet 731 is provided on the bottom wall of the first auxiliary chamber 736. There is a certain distance between the upper end of the first auxiliary chamber 736 and the top wall of the annular chamber 735, so that the heavy oil entering from the third oil inlet 654 of the lower stirring assembly 600 can enter the interior of the first auxiliary chamber 736 through the first oil inlet 731, and then enter the annular chamber 735 through the gap between the top of the first auxiliary chamber 736 and the top wall of the annular chamber 735. The second auxiliary chamber 737 is generally cylindrical with a fan-shaped cross-section. It has an opening on its outer arc surface, communicating with the annular chamber 735. A first oil outlet 733 is located on the inner arc surface of the second auxiliary chamber 737, communicating with the central chamber 734. This allows the heavy oil in the annular chamber 735 to enter the second auxiliary chamber 737 through the opening on its outer arc surface, then through the first oil outlet 733 into the central chamber 734, and finally from the central chamber 734 into the inner oil extraction pipe 500. Simultaneously, the crushing elements include a first crushing element 710 and a second crushing element 720. The first crushing element 710 has a first rotating shaft 711, which is rotatably mounted in the first auxiliary chamber 736 via bearings on both sides. One end of the first rotating shaft 711 passes through the top wall of the annular chamber 735, and the end extending above the annular chamber 735 is provided with a fourth gear 713. The fourth gear 713 meshes with the third gear 630 on the stirring assembly 600 for transmission. The portion of the first rotating shaft 711 located in the first auxiliary chamber 736 is fitted with several sets of first crushing teeth 712, which are arranged parallel to each other. The first rotating shaft 711 is arranged parallel to the direction of heavy oil flow in the first auxiliary chamber 736.The second crushing element 720 has a similar structure to the first crushing element 710, mainly consisting of a second rotating shaft 721 rotatably disposed within the second auxiliary chamber 737. One end of the second rotating shaft 721 passes through the top wall of the annular chamber 735, and the end extending above the annular chamber 735 is equipped with a fifth gear 723. The fifth gear 723 meshes with the third gear 630 on the stirring assembly 600 for transmission. The portion of the second rotating shaft 721 located within the second auxiliary chamber 737 is fitted with several sets of second crushing teeth 722, and the second rotating shaft 721 is positioned perpendicular to the heavy oil flow direction within the second auxiliary chamber 737. In this embodiment, the heavy oil channel within the crushing assembly 700 is formed by the flow from the first oil inlet 731 to the first auxiliary chamber 736, then to the annular chamber 735, then to the second auxiliary chamber 737, and finally from the first oil outlet 733 into the central chamber 734. Furthermore, the first crushing element 710 and the second crushing element 720 are respectively arranged parallel to and perpendicular to the extension direction of the heavy oil channel within the crushing assembly 700, thereby crushing impurities in the heavy oil in different directions, improving the crushing and refining rate of impurities, and reducing the possibility of impurities entering the oil pipeline.

[0055] One specific working method of this embodiment is as follows:

[0056] When extracting heavy oil, firstly, one end of the stirring component 600 of the collection mechanism is inserted downwards into the heavy oil. Then, the suction pump connected to the collection mechanism is started to begin suction and drives the stirring component 600 to rotate, while the inner oil extraction pipe 500 and the housing 730 of the crushing component 700 do not rotate. At this time, the first crushing element 710 and the second crushing element 720 of the crushing component 700 also begin to rotate due to the stirring component 600. Then, the collection mechanism is controlled by the inner oil extraction pipe 500 to continuously extract the heavy oil as it penetrates deeper into the oil. At the same time, the stirring element 620 and the drill bit 652 outside the stirring component 600 clear the surrounding heavy oil. Simultaneously, the first crushing element 710 and the second crushing element 720 process the sucked-in heavy oil, enabling the collection mechanism to stably perform heavy oil collection work for a long time.

[0057] In this embodiment, the heavy oil collection mechanism rotatably mounts a stirring assembly 600 on the inner oil extraction pipe 500, and a crushing assembly 700 is fitted onto one end of the inner oil extraction pipe 500 where the second oil inlet 510 is located. By utilizing the mutual transmission between the third gear 630 on the stirring assembly 600 and the gear on the crushing element of the crushing assembly 700, the high-viscosity heavy oil inside and outside the collection mechanism is processed simultaneously during the extraction of heavy oil. This enables the collection mechanism to operate stably for a long time and solves the problem in the prior art where the ports of heavy oil extraction equipment are difficult to penetrate deep into the heavy oil and are easily blocked by gum, asphalt, and impurities, thereby reducing the working efficiency and stability of the heavy oil extraction equipment.

[0058] Preferably, in this embodiment, a heating component, including a resistance wire electrically connected to an external power source, can be installed inside the inner oil extraction pipe 500. Through conduction through the inner oil extraction pipe 500 wall, the extracted heavy oil is heated, further enhancing the fluidity of the heavy oil and preventing the heavy oil from accumulating inside the collection mechanism.

[0059] Example 2

[0060] Based on the above embodiments, a heavy oil extraction device using this heavy oil collection mechanism is further proposed, and a second embodiment is provided below.

[0061] Please see Figures 1-9 The heavy oil extraction device in the second embodiment is used for heavy oil extraction operations. It leverages the advantages of the heavy oil collection mechanism described in the previous embodiment, adapting to the complex composition of heavy oil, reducing the difficulty of deep extraction, and minimizing equipment blockage. This heavy oil extraction device mainly includes an oil pipeline 100, a pump body 200 on the oil pipeline 100, a mounting frame 300, a motor 400 on the mounting frame 300, and the heavy oil collection mechanism described in the previous embodiment. The oil pipeline 100 has an oil outlet 110 at one end, and the pump body 200 is installed on the pipeline. The other end of the oil pipeline 100 is connected to the second oil outlet 520 of the inner oil extraction pipe 500 of the collection mechanism for heavy oil transportation. Furthermore, the mounting frame 300 is installed on the oil pipeline 100 near the oil inlet, and the motor 400 is located below the mounting frame 300. The inner oil extraction pipe 500 of the collection mechanism is also embedded in the mounting frame 300. Meanwhile, a first gear 410 is provided on the output end of the motor 400. The first gear 410 meshes with the second gear 610 on the stirring assembly 600 of the collection mechanism, thereby providing automated driving force for the collection mechanism. In use, the pump body 200 is started to perform suction, and the collection mechanism is driven by the motor 400, thus enabling the stable suction, transportation and collection of heavy oil for a long time.

[0062] In this embodiment, the heavy oil extraction device is equipped with a heavy oil collection mechanism. A stirring assembly 600 is rotatably mounted on the inner oil extraction pipe 500 of the heavy oil collection mechanism, and a crushing assembly 700 is fitted onto one end of the inner oil extraction pipe 500 where the second oil inlet 510 is located. By utilizing the mutual transmission between the third gear 630 on the stirring assembly 600 and the gear on the crushing element of the crushing assembly 700, the high-viscosity heavy oil inside and outside the collection mechanism is processed simultaneously during the extraction of heavy oil. This enables the collection mechanism to operate stably for a long time and solves the problem in the prior art where the ports of heavy oil extraction equipment are difficult to penetrate deep into the heavy oil and are easily blocked by gum, asphalt, and impurities, thereby reducing the working efficiency and stability of the heavy oil extraction equipment.
