Description

Technical Field

[0001] The invention relates to the technical field of gas well production equipment, in particular to an underground pressure-boosting production and data monitoring device for oil and gas wells. Background Art

[0002] In the oil and gas energy industry, there is no mature supporting technology for the exploitation of low-pressure natural gas wells in China, but there are a large number of low-pressure gas wells in major gas fields in China. In order to solve the drainage problems of low-pressure gas wells with insufficient energy and poor liquid carrying capacity, a bottom hole pressurization process is proposed to increase the production capacity of gas wells. The bottom hole compressor involved in this process is one of the core components of the entire process. There is currently no manufacturing precedent at home and abroad. The quality of its aerodynamic performance directly affects the performance of the whole machine. At present, the compressor is used in ground scenarios such as the aerospace field and the oil field field.

[0003] Domestic related industries have certain technical research in aviation engines and ground gas turbines. As one of its core components, the compressor technology is not yet mature. No research has been conducted on underground compressors. Due to the limitations of underground environmental conditions, the design difficulty is much greater than that of ground equipment. At present, there is still a blank in China. Before 2019, Upwing Company in the United States successfully realized the application evaluation of underground compressor prototypes in 4 wells. The on-site results showed that the average production of natural gas wells increased by more than 40%; after 2019, the product was commercialized, and the natural gas production increased by more than 62%, and the drainage volume increased by more than 50%. Due to the influence of wellbore friction and fluid gravity, the wellhead pressurized gas production can reduce the bottomhole flow pressure to a limited extent. At this time, there is still room for tapping the formation pressure.

[0004] In view of the gap in current technology, an underground pressurized production and data monitoring device for oil and gas wells is invented. The present invention is mainly designed for underground working conditions, with the purpose of achieving negative pressure gas production at the bottom of the well, effectively eliminating friction loss of the wellbore pipe, minimizing the abandoned reservoir pressure, and improving the ultimate recovery rate of the gas reservoir. Summary of the invention

[0005] The purpose of the present invention is to provide an underground pressurized production and data monitoring device for oil and gas wells. The bottom hole gas is sucked into a simulated designed flow channel through the impeller at the inlet of the compressor, and an inlet and outlet pressure ratio of 1:1.5 can be achieved, thereby increasing the gas pressure in the production tubing, reducing the friction loss in the oil pipe, and improving the oil pipe transportation capacity. Therefore, the device can provide a higher productivity than using conventional ground compression. The downhole compressor close to the reservoir can more effectively reduce the gas field abandonment pressure and improve the final recovery rate. The downhole high-speed booster pump is as close to the reservoir as possible, and gas is sucked from the bottom to reduce the bottom hole flow pressure, thereby increasing the flow rate of natural gas from the reservoir to the bottom of the well and accelerating natural gas production. Downhole compression reduces the bottom hole flow pressure and the reservoir abandonment pressure, thereby maximizing the recoverable amount of the gas well reservoir, realizing downhole gas compression, and increasing the bottom hole pressure, providing a good solution for increasing the gas well production or ultimately resuming production.

[0039] In this embodiment, the air pressure monitoring sensor 16 is used to monitor the downhole air pressure in real time. A streamlined flow channel is arranged on the airway housing 7. The streamlined flow channel includes eight air inlet channels 8 opened at one end of the airway housing 7 and four air outlet channels 9 opened at the other end. Every two air inlet channels 8 are merged into an air outlet channel 9 at the other end of the airway housing 7. The gas generated by the rotation of the rotor shaft 4 driving the impeller 5 to rotate passes through the air inlet channel 8 and is finally discharged from the four air outlet channels 9. The merged air outlet channel 9 is twice the channel cross-sectional area of ​​the air inlet channel 8. The channel of the air inlet channel 8 transitions from a spiral to a straight line. The airway streamline is designed by numerical simulation, and the air inlet data simulates the well. Under actual working conditions, the currently used streamlined flow channel is formed, and the data simulation has reached the lowest fluid friction.

[0044] As a further solution of the present invention, the air inlet 6 adopts a streamlined bell-shaped shape.

[0045] In this embodiment, the streamlined bell-shaped shape can increase the gas intake amount and reduce the gas friction resistance.

[0046] As a further solution of the present invention, eight air inlet channels 8 are equiangularly distributed circumferentially on the air duct housing 7, and four air outlet channels 9 are equiangularly distributed circumferentially on the air duct housing 7. The merged air outlet channel 9 is twice the cross-sectional area of ​​the air inlet channel 8, and the channel of the air inlet channel 8 transitions from a spiral to a straight line.

[0047] In this embodiment, the flow channel designs currently known all use a design in which the inlet and outlet are directly connected, and there is no design of merging the outlet. The design in which the inlet and outlet are separately connected is suitable for most of the compressors on the ground. The ground compressor has space for wiring, and the design of the downhole compressor is limited, and a position for wiring needs to be reserved. By setting the air inlet channel 8 and the air outlet channel 9, the air channel streamline is designed through numerical simulation, and the air inlet data simulates the actual working conditions downhole to form the currently used streamlined flow channel.

The overall design is novel and meets the actual working conditions.

[0052] As a further solution of the present invention, the linkage structure includes a movable ring 20 fixed on the rotor shaft 4 and a fixed ring 19 fixed on the filter screen 17.

Dust and impurities adhering to the surface of the filter 17 can be scraped off in time to prevent dust and impurities from clogging the filter holes of the filter 17. Therefore, the air can be filtered through the filter 17 while the air intake flux can be effectively improved.

[0054] As a further solution of the present invention, the corners of the first protrusion 21 and the second protrusion 23 are both processed with arc transition.

[0055] In this embodiment, the friction resistance when the first protrusion 21 and the second protrusion 23 are in surface contact is reduced.

[0056] Working principle of the present invention: the air pressure monitoring sensor 16 is used to monitor the underground air pressure in real time. A streamlined flow channel is arranged on the airway housing 7. The streamlined flow channel includes eight air inlet channels 8 opened at one end of the airway housing 7 and four air outlet channels 9 opened at the other end. Every two air inlet channels 8 are merged into an air outlet channel 9 at the other end of the airway housing 7. The gas generated by the rotation of the impeller 5 passes through the air inlet channel 8 and is finally discharged from the four air outlet channels 9.

The overall design is novel and meets the actual working conditions; in addition, the present invention is equipped with a filter 17 on the air inlet 6, which can be used to filter the gas entering the streamlined flow channel inside the motor body 2 to remove dust and impurities, thereby preventing dust and impurities from entering the motor body 2 and affecting the normal use of the motor body 2 and affecting the life of the motor body 2. By arranging multiple filters on the filter 17 for filtering the gas entering the streamlined flow channel inside the motor body 2, the filter 17 can be used to filter the gas entering the streamlined flow channel inside the motor body 2 to remove dust and impurities. The scraper 18 for scraping dust off the surface of the filter 17 is connected to the rotor shaft 4 through a linkage structure. When the rotor shaft 4 rotates, it will drive multiple scrapers 18 to move horizontally on the surface of the filter 17.
