Description

Technical Field

[0001] This utility model relates to the field of oil pumping device technology, specifically a natural gas extraction oil pumping device. Background Technology

[0002] Natural gas, like crude oil, is buried in closed geological structures underground. Some natural gas is stored in the same stratum as crude oil, while others exist separately. Natural gas stored in the same stratum as crude oil is extracted along with the crude oil. Natural gas reservoirs containing only single-phase gas are called gas reservoirs, and their extraction methods are very similar to those for crude oil, but also have their own unique characteristics. In natural gas extraction, the stable operation of the pumping unit directly affects extraction efficiency and safety.

[0003] Currently, to ensure the safe operation of oil pumping units, the deployment of sensors for gas leaks is crucial during the use of natural gas extraction oil pumping equipment. These sensors are typically located at wellhead seals, pipeline flange / valve connections, pumping unit packing boxes, compressor seals, and separator drain ports. However, these sensors are often deployed in the field, making them susceptible to the effects of rain, snow, and high humidity, which reduces their sensitivity and lifespan, requiring frequent replacement or maintenance. Furthermore, dust adhering to the sensor surface can clog detection holes, leading to response delays. Additionally, natural winds or airflow generated by equipment operation (such as motor cooling) near the pumping unit can disperse leaked natural gas, causing large fluctuations in gas concentration near the leak point, making it difficult for sensors to capture stable signals and resulting in missed detections. Therefore, we propose a new type of natural gas extraction oil pumping device. Utility Model Content

[0004] The purpose of this invention is to provide a natural gas extraction pumping device that has the advantages of good safety and long service life. It solves the problem that sensors are often deployed in the field and are easily affected by external rain, snow and high humidity, which reduces the sensitivity and service life of the sensors.

[0009] Preferably, the detection box is located at the right end of the top of the substrate.

[0010] Preferably, the top of the inner side of the testing box has a lower slot, and the top of the testing box has an upper slot.

[0011] Preferably, a partition is fixedly connected between the left end of the inner side of the exhaust hood and the top of the testing box, and exhaust fans are fixedly installed at both the front and rear ends of the partition.

[0018] 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.

[0019] The components of this application, including the substrate 1, the natural gas extraction pumping equipment body 101, the detection box 2, the exhaust hood 201, the partition 202, the exhaust fan 203, the upper slot 204, the fixing frame 205, the gas detection sensor 206, the lower slot 207, the filter screen 208, the gas collection hood 3, and the gas guide pipe 301, are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0020] Example 1

[0021] Please see Figures 1-3 As shown, this utility model provides a technical solution: a natural gas extraction and pumping device, comprising:

[0022] The substrate 1 has a natural gas extraction pumping equipment body 101 on its top.

[0023] The top of the detection box 2 is fixedly connected to an exhaust hood 201, the inner cavity of the detection box 2 is fixedly connected to a fixing frame 205, the inner side of the fixing frame 205 is fixedly connected to a gas detection sensor 206, and the lower end of the detection box 2 is fixedly connected to a filter screen 208.

[0024] A gas collection hood 3 is fixedly connected to the lower right side of the detection box 2, and a gas guide pipe 301 is provided on the outside of the detection box 2.

[0025] The test box 2 is located at the top right end of the substrate 1. The top of the inner side of the test box 2 has a lower slot 207 and an upper slot 204.

[0026] This technical solution: By setting up the natural gas extraction and pumping equipment body 101, natural gas extraction and pumping can be achieved. With the assistance of the fixing frame 205, the gas detection sensor 206 can be installed in the detection box 2, thereby avoiding the influence of complex external environments, which helps to improve the service life of the gas detection sensor 206 and reduce its replacement or maintenance frequency. Through the setting of the gas collecting hood 3 and multiple gas guide pipes 301, this device can simultaneously guide gas from multiple detection points into the detection box 2 (the detection points include the wellhead seal, pipeline flange / valve connection point, pumping point, etc.). (e.g., oil press packing box), and when the gas passes through the filter screen 208, it can be filtered, thereby filtering out foreign impurities such as dust, preventing them from adhering to the surface of the gas detection sensor 206. After the filtered gas impacts the gas detection sensor 206 through the lower slot 207, it can detect the gas at multiple detection points (if the detected data exceeds the set extreme value, it can be transmitted to the back-end terminal for warning, and at the same time, the on-site information device alarms, which is existing technology, as shown in the figure). Finally, the gas is discharged outward through the upper slot 204 and the exhaust hood 201.

[0027] It should be noted that the natural gas extraction pumping equipment body 101, gas detection sensor 206, filter screen 208, and exhaust fan 203 used in this device can all be purchased directly from the market. At the same time, the connection methods and electrical connections of each component adopt mature conventional methods in the existing technology, and it is powered by mains electricity, so no specific description will be given here.

[0028] Example 2

[0029] Based on Embodiment 1, this utility model is as follows: Figures 1-3 As shown, a partition 202 is fixedly connected between the left end of the inner side of the exhaust hood 201 and the top of the test box 2, and exhaust fans 203 are fixedly installed at both the front and rear ends of the partition 202.

[0030] This technical solution: By setting the partition 202, the exhaust fan 203 can be installed inside the exhaust hood 201. When the device is working, the exhaust fan 203 can accelerate the exhaust of the gas in the detection box 2 to the outside through the exhaust hood 201, thereby attracting the gas from multiple detection points to pass through the detection box 2 quickly, thus improving the detection efficiency and stability of the device.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
