Description

Technical Field

[0001] The present invention belongs to the technical field related to oilfield exploitation equipment, and more specifically, it is a ground multi-component gas generator for oilfield exploitation compressors. Background Art

[0002] The ground multi-component gas generator used in oilfield exploitation is a device for generating high-pressure mixed gas and injecting it into oil wells. It is mainly used to improve the fluidity of crude oil, reduce viscosity or supplement formation energy, thereby enhancing oil recovery. Its core function is to compress, mix and process gases to generate a gas combination that meets specific process requirements, and then inject it into the oil well after boosting through a compressor system:

[0003] The multi-component gas generator usually uses liquid or gas fuel as raw material, and generates high-temperature and high-pressure gas through high-pressure combustion or chemical reaction. For example, in oilfield gas flooding operations, multi-component thermal fluid may be generated by burning fuel and mixing with water, such as a mixture of high-pressure steam and gas. This thermal fluid has a high enthalpy value and can effectively heat the underlying crude oil and reduce its viscosity.

[0004] The application document with the publication number CN113623624A discloses a steam generator, which includes an evaporator, a first pipeline and a second pipeline. One end of the first pipeline is connected to the evaporator, and a storage tank and a first pump body are provided on the first pipeline. The first pump body is located between the storage tank and the evaporator; both ends of the second pipeline are respectively connected to the storage tank and the evaporator, and a first valve body is provided on the second pipeline. The first valve body is a one-way valve. The first medium enters through the first pipeline and is transported into the storage tank, thus ensuring the stable air pressure in the storage tank, and further avoiding the vaporization of superheated water in the storage tank, and thus ensuring that no bubbles enter the first pump body to cause cavitation.

[0005] The above multi-component gas generator has certain deficiencies in use. The traditional multi-component gas generator does not have a multiple heating structure. When it performs water body heating operation, the water body is introduced through a pipe body and heated to generate water vapor. The single heating method reduces its water vapor generation efficiency. At the same time, during the water vapor generation process, the residual water body will be discharged outwards along with the steam, and the residual water body cannot be treated secondarily, reducing its use effect. Summary of the Invention

[0006] The purpose of the present invention is to provide a ground multi-component gas generator for oilfield exploitation compressors, which can solve the existing problems.

[0007] The problems solved by the present invention are:

[0008] 1. Traditional multi-component gas generators do not have a multiple heating structure. When performing water heating operations, water is introduced through a pipe body and heated to generate water vapor. The single heating method reduces the efficiency of water vapor generation. At the same time, during the water vapor generation process, residual water will be discharged outward along with the steam, and the residual water cannot be treated twice, reducing its usage effect.

[0009] The object of the present invention can be achieved by the following technical solutions:

[0010] A ground multi-component gas generator for an oilfield exploitation compressor, comprising a heating tank, a heating kit, and several groups of evaporation rings. Several groups of evaporation rings are fixedly installed in the middle position inside the heating tank. The heating kit is fixedly installed below the heating tank on the outside of the evaporation rings. Several groups of evaporation rings are vertically equally spaced. Several groups of evaporation rings are fixedly connected by a connecting pipe. The inside of the evaporation ring is a hollow structure. An annular coil is fixedly installed inside the heating kit. Several groups of heat conduction rings are vertically distributed on the inner surface of the heating kit. A heater is fixedly installed below the heating kit and the evaporation rings inside the heating tank. The heating kit and the heater, as well as the evaporation ring and the heater, are all connected through.

[0011] As a further technical solution of the present invention, a gas pipe is fixedly installed in the middle position at the upper end of the heating tank. Igniters are respectively arranged on both sides of the gas pipe inside the heating tank. An air pipe is arranged above the igniter inside the heating tank. During operation, gas is transported into the heating tank through the gas pipe, and the gas ejected from the gas pipe is ignited by the igniter, causing the inside of the heating tank to burn and heat. Water can be transported into the inside of the annular coil and the evaporation ring respectively through a water delivery pipe. By heating the annular coil and the evaporation ring, the water evaporates to form water vapor. The setting of the annular coil and the evaporation ring enables a dual heating structure to be formed inside the heating tank, and the inner flame and outer flame of the flame can be fully utilized for heating operations.

[0012] As a further technical solution of the present invention, water delivery pipes are fixedly installed at the upper positions on both sides of the heating tank. Combustion-supporting pipes used in cooperation with the heater are fixedly installed at the lower positions on both sides of the heating tank. The water vapor and part of the water that has not formed water vapor are transported into the inside of the heater, and the combustion-supporting pipe is used to spray flame on the heater for heating, so that the liquid inside the heater is reheated and discharged outward through the exhaust groove of the heater following the water vapor.

[0013] As a further technical solution of the present invention, an annular notch is provided inside the evaporation ring, an exhaust pipe is provided at the lower end of the heating tank, threaded joints for cooperating with the evaporation ring are provided at both ends of the connecting pipe, and the evaporation ring as a whole is an annular hollow structure. When the gas pipe performs a flame spraying and heating operation, the flame can pass through several groups of evaporation rings at the same time. When the water body passes through several groups of evaporation rings from top to bottom, the water body in the evaporation ring is fully heated, generating water vapor and spraying it downward. At the same time, several groups of evaporation rings are vertically equidistantly distributed, so that there is a certain gap between two adjacent evaporation rings. When the flame heats several groups of evaporation rings from top to bottom, part of the flame will overflow outward through the gap between two adjacent evaporation rings, thereby heating the inner surface of the heating kit.

[0014] As a further technical solution of the present invention, the evaporation ring and the heating tank are fixed by docking through a docking rod. One end of the docking rod is fixedly installed with a docking seat for docking with the evaporation ring. To achieve rapid heat conduction of the evaporation ring, the thickness of the evaporation ring is reduced during production. After the thickness is reduced, it is impossible to directly punch holes for fixation. The docking rod and the docking seat can form an auxiliary support structure between the evaporation ring and the heating tank, preventing several groups of vertically arranged evaporation rings from tilting inside the heating tank.

[0015] As a further technical solution of the present invention, a lifting pressure plate is movably installed inside the docking seat, and the docking seat and the lifting pressure plate are driven by a fastening bolt. A threaded groove for cooperating with the docking rod is provided at one end of the docking seat. The user places the docking seat outside the evaporation ring and rotates the fastening bolt, causing the fastening bolt to drive the lifting pressure plate to move downward, thereby completing the fixation operation between the evaporation ring and the docking seat.

[0016] As a further technical solution of the present invention, a hexagonal rotating sleeve is fixedly installed on the outer surface of the connecting pipe, and a fixed base is provided at the bottom of the heating tank. The fixed base plays an auxiliary fixing role for the bottom of the heating tank. By rotating the hexagonal rotating sleeve, the connecting pipe can be driven to fix the connecting pipe between two groups of evaporation rings.

[0017] As a further technical solution of the present invention, several heat conduction columns are fixedly installed inside the heater, and an exhaust groove is provided at the upper inner side of the heater. Several heat conduction columns are in direct contact with the heater. When the surface of the heater is heated, the heat conduction columns can play a heat conduction role, enabling the heat to be quickly transferred to the inside of the heater, playing a secondary heating role for the residual liquid inside the heater and quickly generating water vapor.

[0018] As a further technical solution of the present invention, an air inlet hood is fixedly installed on the outer surface of the upper end of the heater. The evaporation ring and the air inlet hood, as well as the annular coiled pipe and the air inlet hood, are all connected through joints in a penetrating manner. Through the air inlet hood, the water vapor and excess liquid generated after heating the evaporation ring and the annular coiled pipe can be introduced into the interior of the heater.

[0019] As a further technical solution of the present invention, annular clamping grooves are provided at both ends of the heating kit. The heating kit and the heating tank are butted through the annular clamping grooves. A pressure gauge is installed on the top of the heating tank. The annular clamping grooves can play a role in splicing and fixing both ends of the heating kit, facilitating the installation and disassembly operations of the heating kit.

[0020] Advantages of the present invention:

[0021] 1. By providing an evaporation ring and a connecting pipe, when the ground multi-component gas generator for an oilfield exploitation compressor is in use, it has an annular heat conduction structure and can be arbitrarily combined according to the height of the generator, enabling the evaporation ring to be in full contact with the flame and improving the water vapor generation efficiency.

[0022] During operation, gas is transported into the interior of the heating tank through a gas pipe, and the gas ejected from the gas pipe is ignited by an igniter, causing the interior of the heating tank to burn and heat. Water can be transported into the interiors of the annular coiled pipe and the evaporation ring respectively through a water delivery pipe. The overall evaporation ring is an annular hollow structure. When the gas pipe performs a flame spraying and heating operation, the flame can pass through several groups of evaporation rings simultaneously. When the water body passes through several groups of evaporation rings from top to bottom in sequence, the heating operation of several groups of evaporation rings is completed, enabling the water body in the evaporation ring to be fully heated. The water bodies between several groups of evaporation rings are connected in series through a connecting pipe, causing the water body to flow between several groups of evaporation rings from top to bottom. In cooperation with the heating operation of the evaporation rings, the water body is heated into water vapor when flowing between several groups of evaporation rings, causing water vapor to be generated and ejected downward inside the evaporation ring. At the same time, several groups of evaporation rings are vertically equidistantly distributed, resulting in a certain gap between two evaporation rings. When the flame heats several groups of evaporation rings from top to bottom, part of the flame will overflow outward through the gap between two evaporation rings, thereby heating the inner surface of the heating kit. The generated water vapor is introduced into the air inlet hood and discharged outward through an exhaust pipe, supplied to the compressor, and injected into the oil well after being pressurized by the compressor system, reducing the viscosity of the crude oil and increasing its oil production speed.

[0023] 2. By providing a heating kit, when the ground multi-component gas generator for an oilfield exploitation compressor is in use, the use of the evaporation ring is optimized to form a multiple heating structure, improving the water vapor generation efficiency.

[0024] During use, by heating the annular coiled pipe and the evaporation ring, water evaporation forms water vapor. The arrangement of the annular coiled pipe and the evaporation ring enables a dual heating structure to be formed inside the heating tank, allowing the inner flame and outer flame of the flame to be fully utilized for heating operations. When the gas pipe conducts a flame spraying and heating operation inside the heating tank, part of the flame will overflow outward through the gaps between several groups of evaporation rings, thereby heating the surface of the heating kit. The arrangement of the heat conduction ring can increase the heat receiving surface of the heating kit, enabling the annular coiled pipe inside the heating kit to quickly heat up. When water flows through the inside of the annular coiled pipe, the water inside the annular coiled pipe is heated up to form water vapor. By using the annular coiled pipe and the evaporation ring to form an inner and outer double-layer heating structure, the inner flame and outer flame of the flame can be fully utilized to complete the heating operation, reducing heat loss and improving the water vapor generation efficiency.

[0025] 3. By providing a heater, when the ground multi-component gas generator for oilfield exploitation compressors is in use, it has a secondary heating structure, which can heat the residual liquid to prevent water from being discharged outward along with the steam.

[0026] During operation, the water vapor and excess liquid generated after heating the evaporation ring and the annular coiled pipe can be introduced into the inside of the heater through the air inlet hood. The combustion-supporting pipe conducts a flame spraying and heating operation on the heater, causing the liquid inside the heater to be secondarily heated and discharged outward through the exhaust groove of the heater along with the water vapor. When the surface of the heater is heated, the heat conduction column can play a heat conduction role, enabling heat to be quickly transferred to the inside of the heater, secondarily heating the residual liquid inside the heater and causing it to quickly generate water vapor.

[0037] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following combines the drawings and preferred embodiments to detail the specific embodiments, structures, features and their effects of the present invention as follows.

[0038] As Figures 1-8 shown, a ground multi-component gas generator for an oilfield exploitation compressor includes a heating tank 1, a heating kit 4 and several groups of evaporation rings 11. Several groups of evaporation rings 11 are all fixedly installed in the middle position inside the heating tank 1. The heating kit 4 is fixedly installed below the heating tank 1 and outside the evaporation rings 11. Several groups of evaporation rings 11 are vertically equidistantly distributed. Several groups of evaporation rings 11 are butt-joined and fixed through a connecting pipe 12. The inside of the evaporation ring 11 is a hollow structure. An annular coiled pipe 10 is fixedly installed inside the heating kit 4. Several groups of heat conduction rings 19 are vertically distributed on the inner surface of the heating kit 4. A heater 22 is fixedly installed below the heating kit 4 and the evaporation rings 11 inside the heating tank 1. The heating kit 4 and the heater 22, as well as the evaporation rings 11 and the heater 22, are all connected through.

[0039] At the middle position of the upper end of the heating tank 1, a gas pipe 6 is fixedly installed. On both sides of the gas pipe 6 inside the heating tank 1, igniters 5 are respectively arranged. Above the igniters 5 inside the heating tank 1, an air pipe 7 is arranged. During operation, gas is transported into the heating tank 1 through the gas pipe 6, and the gas ejected from the gas pipe 6 is ignited by the igniters 5, so that the inside of the heating tank 1 burns and heats up. The water body can be respectively transported into the inside of the annular coiled pipe 10 and the evaporation ring 11 through the water delivery pipe 8. Through the heating of the annular coiled pipe 10 and the evaporation ring 11, the water body evaporates to form water vapor. The arrangement of the annular coiled pipe 10 and the evaporation ring 11 enables a double heating structure to be formed inside the heating tank 1, and the inner flame and outer flame of the flame can be fully utilized to perform heating operations on it.

[0040] On the upper positions on both sides of the heating tank 1, water delivery pipes 8 are fixedly installed. On the lower positions on both sides of the heating tank 1, combustion-supporting pipes 3 used in cooperation with the heater 22 are fixedly installed. The water vapor and part of the water body that has not formed water vapor are transported into the inside of the heater 22, and the combustion-supporting pipe 3 is used to perform flame spraying and heating on the heater 22, so that the liquid inside the heater 22 is heated for the second time and discharged outward through the exhaust groove 23 of the heater 22 following the water vapor.

[0041] To improve the liquid evaporation efficiency, as Figure 3 shown, an annular notch 13 is arranged inside the evaporation ring 11. An exhaust pipe 2 is arranged at the lower end of the heating tank 1. Threaded joints 20 used in cooperation with the evaporation ring 11 are arranged at both ends of the connecting pipe 12. The evaporation ring 11 is of an overall annular hollow structure, so that when the gas pipe 6 performs flame spraying and heating operations, the flame can pass through several groups of evaporation rings 11 at the same time. When the water body passes through several groups of evaporation rings 11 from top to bottom in sequence, the water body inside the evaporation ring 11 is fully heated, causing it to generate water vapor and spray downward. At the same time, several groups of evaporation rings 11 are vertically equally spaced, so that there is a certain gap between two evaporation rings 11. When the flame performs heating operations on several groups of evaporation rings 11 from top to bottom, part of the flame will overflow outward through the gap between two evaporation rings 11, thereby performing heating operations on the inner surface of the heating kit 4.

[0042] The evaporation ring 11 and the heating tank 1 are butt-jointed and fixed through a butt rod 9. One end of the butt rod 9 is fixedly installed with a butt joint seat 14 for butt-jointing the evaporation ring 11. To achieve rapid heat conduction of the evaporation ring 11, the thickness of the evaporation ring 11 will be reduced during production. After the thickness is reduced, it is impossible to directly drill holes for fixation. The butt rod 9 and the butt joint seat 14 can form an auxiliary support structure between the evaporation ring 11 and the heating tank 1, preventing several groups of vertically arranged evaporation rings 11 from tilting inside the heating tank 1.

[0043] An elevating pressure plate 15 is movably installed inside the docking socket 14, and the docking socket 14 and the elevating pressure plate 15 are driven by a fastening bolt 16. One end of the docking socket 14 is provided with a threaded groove 17 for cooperating with the docking rod 9. The user clamps the docking socket 14 outside the evaporation ring 11 and rotates the fastening bolt 16 to drive the elevating pressure plate 15 to move downward, thereby completing the fixing operation between the evaporation ring 11 and the docking socket 14.

[0044] A hexagonal rotating sleeve 21 is fixedly installed on the outer surface of the connecting pipe 12, and a fixed base 25 is arranged at the bottom of the heating tank 1. The fixed base 25 plays an auxiliary fixing role for the bottom of the heating tank 1. By rotating the hexagonal rotating sleeve 21, the connecting pipe 12 can be driven to fix the connecting pipe 12 between two evaporation rings 11.

[0045] To solve the problem of liquid residue, as Figure 7 shown, a number of heat conducting columns 27 are fixedly installed inside the heater 22, and an exhaust groove 23 is arranged at the upper inner position of the heater 22. A number of heat conducting columns 27 are in direct contact with the heater 22. When the surface of the heater 22 is heated, the heat conducting columns 27 can play a heat conducting role, enabling heat to be quickly transferred to the inside of the heater 22, playing a secondary heating role for the residual liquid inside the heater 22 and making it quickly generate water vapor.

[0046] An air inlet hood 24 is fixedly installed on the upper outer surface of the heater 22. The evaporation ring 11 and the air inlet hood 24, as well as the annular coiled pipe 10 and the air inlet hood 24, are all connected through joints. Through the air inlet hood 24, the water vapor and excess liquid generated after heating the evaporation ring 11 and the annular coiled pipe 10 can be introduced into the inside of the heater 22.

[0047] To improve the liquid evaporation efficiency, as Figure 5 shown, annular clamping grooves 18 are arranged at both ends of the heating kit 4. The heating kit 4 and the heating tank 1 are docked through the annular clamping grooves 18. A pressure gauge 26 is installed at the top of the heating tank 1. The annular clamping grooves 18 can play a role in splicing and fixing both ends of the heating kit 4, facilitating the installation and disassembly operations of the heating kit 4.

[0048] During use, traditional multi - gas generators do not have a multiple heating structure. When performing water body heating operations, the water body is introduced through a pipe and heated to generate water vapor. The single heating method reduces the water vapor generation efficiency. At the same time, during the water vapor generation process, residual water bodies will be discharged outward along with the steam, and the residual water bodies cannot be secondary - treated, reducing their usage effect;

[0049] To this end, by setting the evaporation ring 11 and the connecting pipe 12, when the ground multi-component gas generator for the oilfield exploitation compressor is in use, it has an annular heat conduction structure and can be arbitrarily combined according to the height of the generator, so that the evaporation ring 11 is in full contact with the flame, improving the water vapor generation efficiency;

[0050] During operation, the gas is transported to the inside of the heating tank 1 through the gas pipe 6, and the gas ejected from the gas pipe 6 is ignited by the igniter 5, so that the inside of the heating tank 1 burns and heats. The water body can be transported to the inside of the annular coil 10 and the evaporation ring 11 respectively through the water pipe 8. The whole evaporation ring 11 is an annular hollow structure, so that when the gas pipe 6 performs the flame spraying and heating operation, the flame can pass through several groups of evaporation rings 11 at the same time. When the water body passes through several groups of evaporation rings 11 from top to bottom in turn, the heating operation of several groups of evaporation rings 11 is completed, so that the water body in the evaporation ring 11 is fully heated. The connecting pipe 12 is used to connect several groups of evaporation rings 11 in series, so that the water body flows between several groups of evaporation rings 11 from top to bottom. Combined with the heating operation of the evaporation ring 11, the water body is heated into water vapor when flowing between several groups of evaporation rings 11, so that water vapor is generated inside the evaporation ring 11 and ejected downward. At the same time, several groups of evaporation rings 11 are vertically equidistantly distributed, so that there is a certain gap between two evaporation rings 11. When the flame heats several groups of evaporation rings 11 from top to bottom, part of the flame will overflow outwards through the gap between two evaporation rings 11, so as to heat the inner surface of the heating kit 4. The generated water vapor is introduced into the air inlet hood 24 and discharged outwards through the exhaust pipe 2, supplied to the compressor, and injected into the oil well after being pressurized by the compressor system, so that the viscosity of the crude oil is reduced and its oil output speed is increased;

[0051] By setting the heating kit 4, when the ground multi-component gas generator for the oilfield exploitation compressor is in use, the use of the evaporation ring 11 is optimized to form a multiple heating structure, improving the water vapor generation efficiency;

[0052] During use, by heating the annular coiled pipe 10 and the evaporation ring 11, water evaporation forms water vapor. The arrangement of the annular coiled pipe 10 and the evaporation ring 11 enables a dual heating structure to be formed inside the heating tank 1, and the inner flame and outer flame of the flame can be fully utilized for heating operations. When the gas pipe 6 performs a flame spraying heating operation on the inside of the heating tank 1, part of the flame will overflow outward from the gaps between several groups of evaporation rings 11, thereby heating the surface of the heating kit 4. By using the arrangement of the heat conduction ring 19, the heat receiving surface of the heating kit 4 can be increased, enabling the annular coiled pipe 10 inside the heating kit 4 to quickly heat up. When water flows through the inside of the annular coiled pipe 10, the water inside the annular coiled pipe 10 is heated up to form water vapor. By using the annular coiled pipe 10 and the evaporation ring 11 to form an inner and outer double-layer heating structure, the inner flame and outer flame of the flame can be fully utilized to complete the heating operation, reduce heat loss, and improve the water vapor generation efficiency;

[0053] By providing the heater 22, when the ground multi-gas generator for an oilfield exploitation compressor is in use, it has a secondary heating structure and can perform a heating operation on the residual liquid to prevent water from being discharged outward along with the steam;

[0054] During operation, the water vapor and excess liquid generated after heating the evaporation ring 11 and the annular coiled pipe 10 can be introduced into the inside of the heater 22 through the air inlet hood 24. The combustion assisting pipe 3 is used to perform a flame spraying heating on the heater 22, so that the liquid inside the heater 22 is secondarily heated and discharged outward through the exhaust groove 23 of the heater 22 following the water vapor. When the surface of the heater 22 is heated, the heat conduction column 27 can play a heat conduction role, enabling heat to be quickly transferred to the inside of the heater 22 and secondarily heating the residual liquid inside the heater 22 to quickly generate water vapor.

Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
