Description

Technical Field

[0001] This invention relates to the field of microbial enhanced oil recovery technology, specifically to an intelligent injection device for microbial enhanced oil recovery agents. Background Technology

[0002] Microbial enhanced oil recovery (DEOR) technology refers to injecting microorganisms and their nutrient sources into oil reservoir formations. On the one hand, it utilizes the direct action of the microorganisms to improve the physical properties and fluidity of crude oil. On the other hand, it utilizes the metabolic products of microorganisms, such as organic acids, biosurfactants, and polymers, which have oil displacement effects, to improve crude oil recovery.

[0003] Microbial species are classified into three categories: aerobic bacteria, facultative anaerobic bacteria, and absolute anaerobic bacteria. During microbial enhanced oil recovery (EOR), in the deep reservoir or near the production well, i.e., under anaerobic conditions, aerobic or facultative anaerobic oil-producing bacteria grow and metabolize slowly, resulting in lower oil recovery capabilities. In the near-wellbore area, when an appropriate amount of oxygen is added, the growth and metabolism of aerobic or facultative anaerobic microorganisms can be accelerated, promoting their proliferation and forming an effective microbial field, which is more conducive to improving oil recovery.

[0004] Currently, the main surface process equipment for microbial enhanced oil recovery consists of a fermentation tank → liquid preparation tank → injection pump → injection wellhead. There is little consideration for measures to enhance microbial growth and metabolism through air injection slugs for oxygen supplementation. It is necessary to study air-assisted microbial enhanced oil recovery surface injection devices.

[0005] A search revealed that CN216617486U discloses a microbial oil-reducing air injection device, comprising a device body, an inlet nozzle at one end of the device body, an outlet at the end of the device body away from the inlet nozzle, and an air intake mechanism within the device body. The air intake mechanism includes an aeration pipe disposed within the device body and a turbulence impeller fitted onto the aeration pipe. The aeration pipe is provided with aeration holes evenly distributed on the aeration pipe, and an air inlet pipe is disposed on one side of the aeration pipe. This patent utilizes the aeration pipe to disperse the incoming gas and the turbulence impeller to disperse the water flow, thereby achieving thorough mixing of air and water and solving the problems of incomplete and uneven mixing between air and water, as well as limited mixing effect.

[0006] CN203685150U discloses an injection and air field injection device for microbial enhanced oil recovery, comprising an injection preparation section, an injection pressurization section, a water supply main line, an air distribution section, an automatic control section, an injection well group, high-pressure valves, and high-pressure pipelines. The injection preparation section consists of a buffer tank, a feed pump, a bacterial solution tank, a nutrient solution tank, and a liquid flow meter. The injection pressurization section consists of a feed pump, a mixing tank, a filter, a plunger pump, a safety valve, a check valve, and a pressure gauge. The air distribution section consists of an air compressor, a gas flow meter, and a check valve. This patent enables simultaneous injection of both injection agents and air in the field, improving the efficiency of intelligent and automated injection.

[0007] However, in practical applications and research, the patent has found that during the process of microbial flooding, reservoir microorganisms and bacteria tend to aggregate and form micelles, which greatly reduces the permeability and easily leads to blockage, affecting the oil displacement efficiency. Therefore, we propose an intelligent injection device for microbial flooding. Summary of the Invention

[0024] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention utilizes the drive component designed in the adjustment component to drive the pulley component, and the support column slides inside the sleeve through the pulley component, which is conducive to the reciprocating motion at the baffle and realizes the passage of microorganisms. When the microbial monitoring unit detects the proportion of oil-displacing and unblocking microorganisms in the oil reservoir formation, if the proportion is normal, there is no need to inject oil-displacing and unblocking microorganisms. If the proportion is small, the electromagnet is energized according to the proportion (if the proportion is small, the electromagnet energizing power is increased; if the proportion is large, other types of microorganisms are injected to keep the ecology as balanced as possible). An appropriate amount of oil-displacing and unblocking microorganisms can be effectively injected to change the number of microorganisms under the oil reservoir formation and avoid the blockage situation, so that the subsequent nutrient injection can be fully absorbed by the microorganisms and achieve the purpose of improving the oil displacement efficiency.

[0025] (2) Under the action of the injection component, the central control panel can set the number of rotations of the servo motor. After rotating a certain number of times, the rotation stops. The time of stopping the rotation is determined according to the amount of nutrient injected. The servo motor drives the through column to rotate through gear one and gear two. During the rotation of the through column, the first action rod on the connecting ring first contacts the force rod and acts on it. The force rod is driven by the force to drive the force panel to perform synchronous action, so that the roller body moves to the rising area. Under the action of the roller body, the output pipe is driven to perform directional rising action through the L-shaped force rod. This can effectively increase the proportion of microorganisms with oil displacement function in the oil reservoir. Therefore, by utilizing the structural design of this invention, the overall microbial oil displacement efficiency can be improved, and the waste of resources can be avoided.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-13 This invention provides a technical solution: an intelligent injection device for microbial enhanced oil recovery, comprising an operating platform 1, which further includes a storage area 11, an output area 12, and a support area 13. The storage area 11 includes a microbial monitoring unit 111, a sampling tube 112, a nutrient addition unit 113, a microbial injection unit 114, and a control area 115. Both the nutrient addition unit 113 and the microbial injection unit 114 are equipped with inlets 9. The bottom inner wall of the output area 12 is sloped, and an injection port 8 is installed on one side of the output area 12. The sampling tube 112... The sampling tube 112 is connected to the microbial monitoring unit 111. Specifically, the sampling tube 112 extracts water samples from the reservoir formation and transfers the samples to the microbial monitoring unit 111 for monitoring. If there are few oil-disrupting and unblocking microorganisms in the reservoir formation, it indicates that there may be blockage in the reservoir formation. If nutrients and microorganisms are directly injected, the oil displacement efficiency will be low. At the same time, the microbial monitoring unit 111 can also determine the type of microorganisms in the reservoir formation. This further illustrates that most existing microbial oil displacement processes utilize hydrocarbon oxidizing bacteria, but in actual operation... Currently, the microorganisms within the oil reservoir contain a large number of bacteria without oil displacement function. This is largely due to the slow metabolic rate and low proportion of hydrocarbon-oxidizing bacteria. Nutrient addition unit 113 can add appropriate nutrients to the oil reservoir, gradually increasing the number of hydrocarbon-oxidizing bacteria. This activates the hydrocarbon-oxidizing bacteria, producing bio-emulsifiers to emulsify the crude oil and improve oil displacement efficiency. When microbial monitoring unit 111 detects a low number of oil displacement and unblocking microorganisms in the oil reservoir, microbial injection unit 114 will inject oil displacement and unblocking microorganisms... Biological agents are injected into the reservoir formation (e.g., Streptococcus thermophilus or Bifidobacterium, Bacillus subtilis or Bacillus licheniformis, wherein Streptococcus thermophilus, Bifidobacterium and Bacillus subtilis are anaerobic microorganisms, while Bacillus licheniformis is an aerobic-anaerobic microorganism). The control area 115 is equipped with a control component 2, which is used to control the amount of microorganisms injected based on the detection results of the microbial monitoring unit 111. An injection component 3 for intelligently injecting nutrients into the reservoir formation is provided in the output area 12. A central control panel 131 is provided on the output area 12.

[0030] The microbial injection unit 114 includes region I 116, region II 117, and region III 118. Partitions 119 are fixedly installed between region I 116 and region II 117, and between region II 117 and region III 118. Through holes 110 are provided at the bottom of region I 116, region II 117, and region III 118. When the microbial monitoring unit 111 detects a lack of corresponding microorganisms in the reservoir formation, an appropriate amount of microorganisms will be injected into the output region 12 through the microbial injection unit 114 (oil-displacing and unblocking microorganisms, or other types of microorganisms, can be injected). The nutrient addition unit 113 includes an organic nutrient region 4 and an inorganic nutrient region 5. A human-shaped guide plate 6 is fixedly installed inside the nutrient addition unit 113, and a cylindrical column 7 is fixedly installed inside the nutrient addition unit 113. One end of the cylindrical column 7 penetrates the inner wall of the nutrient addition unit 113 and extends into the output region 12. For details, see attached. Figure 1-3 As shown: Before injecting nutrients and microorganisms into the oil reservoir, the water quality in the oil reservoir is sampled through sampling tube 112, and the microorganisms in the water are monitored through microbial monitoring unit 111. When a small number of oil-displacing and unblocking microorganisms (the microorganisms mentioned above) are detected, the microorganisms in the oil reservoir may aggregate to form flocs. Then, an appropriate amount of microorganisms is injected into the oil reservoir through regulating component 2 (the efficiency of oil-displacing and unblocking microorganisms is relatively low compared to specialized oil-displacing microorganisms, so an appropriate amount is needed to avoid drastically disrupting the relative balance in the oil reservoir). When the microbial monitoring unit 111 detects a small amount of hydrocarbon microorganisms in the water, organic nutrients are first injected into the oil reservoir through injection component 3. Organic nutrients can quickly promote the overall proliferation and metabolism of hydrocarbon microorganisms, increasing their proportion in the oil reservoir. Then, inorganic nutrients are injected, activating the hydrocarbon microorganisms to produce bio-emulsifiers to emulsify crude oil, thereby increasing the oil displacement rate of the oil reservoir. Furthermore, the present invention utilizes the regulating component 2 to effectively inject an appropriate amount of oil-displacing and unblocking microorganisms, thereby changing the number of microorganisms in the reservoir formation and avoiding blockage. This allows the subsequent injection of nutrients to be fully absorbed by the microorganisms, achieving the goal of improving oil displacement efficiency. Under the action of the injection component 3, the proportion of microorganisms with oil displacement function in the reservoir formation can be effectively increased. Thus, by utilizing the structural design of the present invention, the overall microbial oil displacement efficiency can be improved, avoiding resource waste.

[0031] As attached Figure 4-7As shown: As a further limitation of the present invention, the adjustment component 2 includes a baffle 21 fixedly installed on the inner wall of the control area 115, wherein the baffle 21 can be divided into a downward slope shape and a vertical shape (not labeled in the figure), wherein the baffle 21 is located below the bottom of the microbial injection unit 114, and a plurality of sleeves 22 are fixedly installed on the baffle 21, and a support column 23 for sliding connection is installed inside the sleeve 22, and a sealing plug 24 is fixedly installed at one end of the support column 23 near the bottom of the microbial injection unit 114. Further, the sealing plug 24 is initially in the through hole 1. Inside the 10, a sealing function is provided, and a support panel 25 is fixedly installed at the other end of the support column 23. A spring body 26 is connected between the support panel 25 and the sleeve 22 (in the initial state, the spring body 26 is in a compressed state). A pulley component 27 (composed of a small column and a pulley, with the pulley and the small column being rotatably connected; the pulley component 27 is prior art, and therefore the small column and pulley are not labeled in the attached drawings) is provided inside the control area 115. A drive component 28 is provided inside the control area 115 to control the directional movement of the pulley component 27. As a further definition of the adjustment component 2 in this invention, the driving component 28 includes an electromagnet 281 fixedly installed on the inner wall of one side of the control area 115, and multiple limiting plates 282 fixedly installed on both the control area 115 and the inner wall of the baffle 21. A slide rail 283 is fixedly installed on the bottom inner wall of the control area 115, and multiple driving blocks 284 for sliding connection with the slide rail 283 are installed on the slide rail 283. A magnet block 285 is fixedly installed at the end of one of the driving blocks 284 (the driving block 284 near the electromagnet 281), and slots 286 are provided inside the other multiple driving blocks 284. T-shaped blocks 287 for sliding connection with the slots 286 are fixedly installed at the ends of the driving blocks 284. A second spring body 288 is installed on the limiting plate 282, and the two sides of the driving block 284 are connected to the second spring body 288. The components are in contact (initially in contact). The drive block 284 includes a sealing area 289 and a descending area 280. When the electromagnet 281 is energized, it generates an attraction force on the magnet block 285. The electromagnet 281 is electrically connected to the central control panel 131. It should be noted that the microbial injection unit 114 in this invention consists of three areas: the through hole 110, the sleeve 22, the support column 23, the sealing plug 24, the support panel 25, the spring body 26, the pulley 27, and the drive block 284 are all three (the specific number can be designed according to the actual use). The current carrying capacity of the electromagnet 281 is determined according to the detection results of the microbial monitoring unit 111. When there are fewer oil-dissolving and unblocking microorganisms, the current carrying capacity of the electromagnet 281 increases under the action of the central control panel 131. Specifically, when the microbial monitoring unit 111 detects the proportion of oil-displacing and unblocking microorganisms in the oil reservoir formation, if the proportion is normal, there is no need to inject oil-displacing and unblocking microorganisms. If the proportion is low, the electromagnet 281 is energized according to the proportion (if the proportion is low, the current of the electromagnet 281 is increased; if the proportion is high, other types of microorganisms are injected to keep the ecology as balanced as possible). Scenario 1: The proportion is slightly less than the normal value. Electromagnet 281 is supplied with a small amount of current, which attracts magnet 285. Magnet 285 drives the corresponding drive block 284 (the drive block 284 near electromagnet 281) to perform directional action (at this time, the T-shaped block 287 on the drive block 284 and the slot 286 on the second drive block 284 are in contact but do not affect it). The pulley 27 moves from the sealing area 289 to the initial position of the descending area 280. The spring body 26 in the compressed state acts on the support panel 25, so that the pulley 27 is in contact with the descending area 280. Thus, the sealing plug 24 is driven to leave the through hole 110 through the support panel 25 and the support column 23 in sequence. At this time, the microorganisms in area I 116 move to the output area 12 through the baffle 21 and are injected into the oil reservoir through the injection port 8. Scenario 2: The proportion is relatively smaller than the normal value (the amount of oil-displacing and unblocking microorganisms in this case is less than in Scenario 1). Increase the current applied to the electromagnet 281. The attraction of the electromagnet 281 to the magnet block 285 increases. The T-shaped block 287 at the end of one of the driving blocks 284 (the driving block 284 near the electromagnet 281) moves to the inner wall of the slot 286 on the second driving block 284 and acts on it. The second driving block 284 performs a directional action (the T-shaped block 287 at the end of the second driving block 284 contacts the slot 286 on the third driving block 284 but does not act on it). Repeat the above action (the first pulley 27 is located in the middle of the descending area 280). At this time, the second sealing plug 24 leaves the through hole 110, thereby increasing the amount of oil-displacing and unblocking microorganisms injected. Scenario 3: The proportion is much smaller than the normal value (there are fewer oil-displacing and unblocking microorganisms in this case than in Scenario 2). The current of electromagnet 281 reaches its maximum value, and the attraction of electromagnet 281 to magnet block 285 continues to increase. The T-shaped block 287 at the end of one of the driving blocks 284 (the driving block 284 near electromagnet 281) moves to the inner wall of the slot 286 on the second driving block 284 and acts on it. The T-shaped block 287 on the second driving block 284 acts on the inner wall of the slot 286 on the third driving block 284. The above actions are repeated. At this time, all three through holes 110 are open. A large number of microorganisms move along the baffle 21 to the output area 12 and are injected into the oil reservoir through the injection port 8. After the time is set by the central control panel 131, electromagnet 281 is de-energized. Under the action of spring body 288, the three driving blocks 284 return to the initial state. Correspondingly, under the action of spring body 26, the sealing plug 24 re-enters the through hole 110 and seals it.

[0032] As a further limitation of the present invention, as shown in the appendix Figure 8-13 As shown, the injection component 3 includes an output pipe 31 disposed inside the output area 12, and the output pipe 31 is located inside the cylindrical column 7 and is slidably connected to it. Both the output pipe 31 and the cylindrical column 7 are provided with feed grooves 32. In the initial state, the feed groove 32 of the output pipe 31 is located below the feed groove 32 of the cylindrical column 7. In the initial state, since the feed groove 32 of the output pipe 31 is below the feed groove 32 of the cylindrical column 7, the nutrients in the nutrient addition unit 113 cannot enter the output pipe 31. A power component 33 is provided at the bottom of the output area 12, and a force-bearing component 34 is provided at the end of the output pipe 31.

The penetrating column 335 penetrates the protective frame 331 and the inner wall of the output area 12 and extends into the interior of the output area 12 (rotatably connected to the protective frame 331 and the inner wall of the output area 12). The end of the penetrating column 335 within the output area 12 is provided with an actuating member 35 for driving the output pipe 31 to perform a directional upward movement. The actuating member 35 includes a connecting collar 351 fixedly installed on the penetrating column 335, and two actuating rods 352 are installed on the connecting collar 351. Further, the angle difference between the actuating rods 352 is 70°. The specific angle design can be set according to actual usage. It should be noted that, as shown in the attached... Figure 10 As shown in the figure (top view): In this solution, the central control panel 131 can set the number of rotations of the servo motor 332. After rotating a certain number of times, the rotation stops. The time for stopping the rotation is determined by the amount of nutrient injected. In this invention, the servo motor 332 drives the through column 335 to rotate through gear 1 333 and gear 2 334. The through column 335 can only rotate counterclockwise as shown in the figure. As a further definition of the injection component 3 of the present invention, the force-receiving component 34 includes an L-shaped force-applying rod 341 fixedly installed at the end of the output pipe 31, and a roller body 342 for rotatably connecting thereto is installed on the L-shaped force-applying rod 341. A force-receiving panel 343 for slidingly connecting to its inner wall is installed inside the output area 12, and a force-receiving rod 344 is installed at the end of the force-receiving panel 343. The force-receiving rod 344 is located on the movement trajectory of the actuating rod 352. A return spring 345 is connected to the inner wall of the output area 12. One end of the force-receiving panel 343 is in contact with the return spring 345. It should be noted that the force-receiving panel 343 includes a bottom area. The force-bearing panel 343 and the roller body 342 are slidably connected. In the initial state (i.e., the feed trough 32 of the output pipe 31 is below the feed trough 32 of the cylindrical column 7), the roller body 342 is located in the bottom area 346 of the force-bearing panel 343. The bottom of the force-bearing panel 343 is provided with a limiting groove 36, and the limiting groove 36 includes a sliding area 361, a snap-fit ​​area 362, a return area 363 and a guide block 364. A rotating rod 365 for rotatably connecting with the output area 12 is installed on the inner wall of the output area 12, and a telescopic column 366 for slidably connecting with the limiting groove 36 is installed at the end of the rotating rod 365.

[0033] Specifically, when the microbial monitoring unit 111 detects the water quality in the oil reservoir formation, if there are many non-oil-displacing microorganisms in the water, the central control panel 131 sends a signal to the servo motor 332. The servo motor 332 rotates clockwise, that is, gear one 333 rotates clockwise synchronously with it. Gear one 333 meshes with gear two 334 to rotate, and gear two 334 drives the through column 335 to rotate counterclockwise. The central control panel 131 sets the number of revolutions and the speed of the servo motor 332 (which can be set according to the actual situation). In this invention, after the through column 335 rotates 90°, the servo motor 332 stops for 30 seconds. During the rotation of the through column 335, the first actuating rod 352 on the connecting ring 351 first contacts the force-bearing rod 344 and acts on it. The force-bearing rod 344 is driven by the force to drive the force-bearing panel 343 to move synchronously, thereby causing the roller body 342 to move to the rising area 347 (the roller body 342 is passively moved). (Motion), so that under the action of the roller body 342, the output pipe 31 is driven to perform a directional upward movement through the L-shaped force bar 341. At this time, the feed trough 32 of the output pipe 31 is located at the feed trough 32 of the cylindrical column 7. To further explain, the length of the feed trough 32 of the output pipe 31 is greater than that of the feed trough 32 of the cylindrical column 7, so that the nutrient in the organic nutrient area 4 moves through the output pipe 31 into the output area 12, and enters the injection port 8 along the bottom inner wall of the output area 12, thereby injecting... Upon entering the reservoir formation, the first actuating rod 352 acts on the force-bearing rod 344 simultaneously, while the telescopic column 366 moves directionally along the locking groove. It first moves along the sliding area 361. When it reaches the end of the sliding area 361, the return spring 345 is compressed to its maximum value, and the first actuating rod 352 is about to separate from the force-bearing rod 344. Continuing to rotate, the first actuating rod 352 separates from the force-bearing rod 344, at which point the telescopic column 366 moves into the locking area 362, as shown in the attached diagram. Figure 12-13As shown, at this time, the telescopic rod performs a directional action on the return action of the force-bearing panel 343, thereby positioning the feed trough 32 of the output pipe 31 at the feed trough 32 of the cylindrical column 7, and the organic nutrient agent continues to flow out. When the servo motor 332 stops rotating, the first action rod 352 no longer acts on the force-bearing rod 344, and the second action rod 352 does not contact the force-bearing rod 344. After 30 seconds, the servo motor 332 continues to rotate, and the through column 335 rotates 220°. During this process, the second action rod 352 acts on the force-bearing rod 344, and the force-bearing rod 344, under the action of the force, drives the force-bearing panel 343 to perform a directional action, causing the telescopic column 366 to... From the snap-fit ​​area 362 to the initial end of the return area 363, under the action of the return spring 345, the telescopic column 366 moves to the end of the return area 363 (i.e., returns to the initial state). At this time, the feed trough 32 of the output pipe 31 is below the feed trough 32 of the cylindrical column 7. The through column 335 continues to rotate, and the first action rod 352 on it will act on the force rod 344 corresponding to the inorganic nutrient area 5. Repeat the above action, stop for 30 seconds, and the servo motor 332 continues to rotate. Repeat the above action to allow the inorganic nutrient agent to enter the oil reservoir formation. Thus, through the structural design of the present invention, the oil displacement efficiency of microorganisms can be fully improved.
