Description

Technical Field

[0001] This invention belongs to the field of petroleum extraction technology, specifically relating to a device for preparing dissolved polymer microsphere composite unblocking acid. Background Technology

[0002] As oilfields enter the later stages of exploitation, the water cut in oil wells continues to rise. To improve the sweep efficiency of injection wells and reduce water cut, some oilfields have begun to widely promote polymer microsphere water shut-off and profile control agents in recent years. However, in some oilfields, the high injection pressure after these measures has led to an increase in under-injection wells. The polymer microspheres flowed back from the injection wells cannot be dissolved by acids (hydrochloric acid, terpineic acid, polyhydrogen acid, etc.), alkalis (sodium hydroxide, monoethanolamine, potassium hydroxide), oxidants (hypochlorous acid, chlorine dioxide, ammonium persulfate, etc.), organic solvents (benzene, toluene, carbon tetrachloride, etc.), or salts (ammonium chloride, potassium chloride, sodium chloride, etc.).

[0003] At room temperature, glycolic acid, triethylenetetraminehexaacetic acid, ethylene glycol butyl ether, and water were added sequentially to the reactor. After stirring for 30 minutes, sodium nonylphenol polyoxyethylene ether sulfate and polyoxyethylene laurate LAE-4 were added, and the mixture was stirred for another 30 minutes to obtain a dissolved polymer microsphere composite unblocking acid. However, after stirring the reactants in the reactor using a stirring mechanism, some residual reactants adhered to the stirring mechanism. Conventional cleaning methods simply involve adding water to the reactor and then stirring with the stirring mechanism to clean the reactant residues adhering to the inner wall of the reactor and the stirring mechanism itself. However, some strongly adhesive reactant residues are difficult to remove. If the reactant residues are not cleaned in time, it will affect the normal ratio of reactants for the next preparation of unblocking acid, thus affecting the normal use effect of the unblocking acid. Summary of the Invention

[0004] The purpose of this invention is to provide a device for preparing polymer-depolymerizing microspheres and unblocking acids, thereby solving the problem in the prior art that it is difficult to clean the reactants remaining on the inner wall of the reactor and the body of the stirring mechanism.

[0005] The technical solution adopted in this invention is a preparation device for dissolving polymer microspheres and unblocking acid, including a reaction vessel.

[0023] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0024] This invention provides an apparatus for preparing dissolved polymer microspheres composite unblocking acids, such as... Figure 1-3 As shown, the reactor includes a reaction vessel 1. A limiting groove 2 is provided inside the reaction vessel 1, and a sealing cover 3 is slidably connected inside the limiting groove 2. A sealing gasket is pasted on the part of the limiting groove 2 that contacts the sealing cover 3, which can improve the sealing effect of the reaction vessel 1 and prevent the reaction from overflowing when the reaction is stirred. An extension plate is designed at each of the four corners of the sealing cover 3, and the outer surface of the extension plate contacts the outer surface of the reaction vessel 1, thereby ensuring the stability of the sealing cover 3 when it moves up and down.

[0025] like Figure 1 and Figure 2 As shown, the inside of the sealing cover 3 is fixedly connected to the feed pipe 4. Multiple feed pipes 4 can be designed to simultaneously add multiple reactants to the reactor 1, thereby improving the operating efficiency of the device.

[0026] like Figure 1 and Figure 4As shown, the sealing cover 3 is equipped with a stirring mechanism 5 inside. The stirring mechanism 5 includes a first motor 501. The outer surface of the first motor 501 is fixedly connected to the outer surface of the sealing cover 3. The output end of the first motor 501 is fixedly connected to a rotating shaft 502. The outer surface of the rotating shaft is rotatably connected to the inside of the sealing cover 3. A first scraper 503 is fixedly connected to the end of the rotating shaft 502 away from the first motor 501. The outer surface of the first scraper 503 is in contact with the inner wall of the reactor 1. A stirring rod 504 is fixedly connected to the outer surface of the rotating shaft 502. A second scraper 505 is fixedly connected to the end of the stirring rod 504 away from the rotating shaft 502. The outer surface of the second scraper 505 is in contact with the inner wall of the reactor 1.

[0027] By starting the first motor 501, the rotating shaft 502 can be driven to rotate. At this time, the rotating shaft 502 can drive the first scraper 503, the stirring rod 504 and the second scraper 505 to rotate as well. The stirring rod 504 can fully stir and mix the reactants, thereby accelerating the reaction efficiency. During cleaning, clean water can be injected into the reactor 1 through the feed pipe 4, and then the clean water is stirred by the stirring mechanism 5. At this time, the first scraper 503 and the second scraper 505 can scrape and clean the reactant residue on the inner wall of the reactor 1.

[0028] like Figure 1 and Figure 5 As shown, a lifting mechanism 6 is provided on the outside of the reactor 1. The lifting mechanism 6 includes a fixed plate 601. The outer surface of the fixed plate 601 is fixedly connected to the outer surface of the reactor 1. A second motor 602 is fixedly connected to the outer surface of the fixed plate 601. An adjusting screw 603 is fixedly connected to the output end of the second motor 602. The outer surface of the adjusting screw 603 is rotatably connected to the inside of the fixed plate 601. A limit plate 604 is rotatably connected to the outer surface of the adjusting screw 603. The outer surface of the limit plate 604 is fixedly connected to the outer surface of the reactor 1. An adjusting plate 605 is threadedly connected to the outer surface of the adjusting screw 603. The outer surface of the adjusting plate 605 is fixedly connected to the outer surface of the sealing cover 3.

[0029] The second motor 602 and water pump 901 are started by the external controller. At this time, the second motor 602 will drive the adjusting screw 603 to rotate. The adjusting screw 603 will drive the adjusting plate 605 to move upward. At the same time, the adjusting plate 605 will drive the sealing cover 3 to move upward, which in turn will drive the feed pipe 4 and the stirring mechanism 5 to move upward.

[0030] like Figure 1 As shown, a first support plate 7 is fixedly connected to the outer surface of the reactor 1, and a second support plate 8 is fixedly connected to the outer surface of the reactor 1. A cleaning mechanism 9 is provided above the first support plate 7. Figure 6As shown, the cleaning mechanism 9 includes a water pump 901. The outer surface of the water pump 901 is fixedly connected to the outer surface of the first support plate 7. A water pump pipe 902 is fixedly connected inside the water pump 901. A water delivery pipe 903 is fixedly connected inside the water pump pipe 902. The water delivery pipe 903 passes through the interior of the second support plate 8. A diversion pipe 904 is fixedly connected to the end of the water delivery pipe 903 away from the water pump 901. The outer surface of the diversion pipe 904 is fixedly connected to the outer surface of the second support plate 8. A plurality of nozzles 905 arranged at equal intervals are fixedly connected inside the diversion pipe 904.

[0031] The end of the water pump 902 away from the water pump 901 can be connected to a water source, allowing water to be drawn from the source for use. When the water pump 901 is started, it draws clean water from the tank into the water delivery pipe 903 via the water pump 902. The clean water then enters the distribution pipe 904 through the water delivery pipe 903 and is finally sprayed onto the stirring mechanism 5 through the nozzle 905. Simultaneously, the first motor 501 can be started to rotate the shaft 502, the first scraper 503, the stirring rod 504, and the second scraper 505, increasing the spray range of the nozzle 905. This ensures timely cleaning of reactant residues adhering to the stirring mechanism 5, preventing interference with the correct reactant ratio for the next preparation of the unblocking acid and guaranteeing its effective use.

[0032] like Figure 1 As shown, the reactor 1 is fixedly connected to the inside of the discharge pipe 10, and a control valve is installed on the discharge pipe 10 to control the discharge flow rate of the reactants. Two sets of support legs 11 are fixedly connected to the bottom surface of the reactor 1.

[0033] The working principle of the apparatus for preparing the polymer microsphere composite unblocking acid of the present invention is as follows:

[0034] In use, this invention first adds glycolic acid, triethylenetetraminehexaacetic acid, ethylene glycol butyl ether, and water sequentially into the reaction vessel 1 through the feed pipe 4. Then, the first motor 501 is started by an external controller. At this time, the first motor 501 drives the rotating shaft 502 to rotate, and the rotating shaft 502 drives the first scraper 503, the stirring rod 504, and the second scraper 505 to rotate as well, thereby achieving thorough stirring of the reactants. After stirring for 30 minutes, sodium nonylphenol polyoxyethylene ether sulfate and polyoxyethylene laurate LAE-4 are added, and stirring is continued for another 30 minutes. After a few minutes, the dissolved polymer microsphere composite unblocking acid is obtained. This unblocking acid can be discharged through discharge pipe 10 for use. The aforementioned dissolved polymer microsphere composite unblocking acid can be directly used in reservoir acidizing operations. It can remove polymer microsphere blockages retained in the formation and dissolve carbonate blockages caused by incompatibility between injected water and formation water. It also forms chelates with calcium and iron ions, effectively inhibiting the formation of secondary precipitation of these substances. After the unblocking acid obtained from this stirring process is used up, the stirring mechanism and the inside of the reaction vessel need to be cleaned. Water is injected into the reactor 1 through the feed pipe 4, and then stirred by the stirring mechanism 5. At this time, the first scraper 503 and the second scraper 505 scrape and clean the reactant residue on the inner wall of the reactor 1. Then, the second motor 602 and water pump 901 are started by the external controller. The second motor 602 drives the adjusting screw 603 to rotate, which in turn drives the adjusting plate 605 to move upwards. Simultaneously, the adjusting plate 605 drives the sealing cover 3 to move upwards, which in turn drives the feed pipe 4 and the stirring mechanism 5 to move upwards as well. The water pump 901 draws clean water from the water tank into the water delivery pipe 903 through the water pumping pipe 902. The clean water then enters the diversion pipe 904 through the water delivery pipe 903 and is finally sprayed onto the stirring mechanism 5 through the nozzle 905. At the same time, the first motor 501 can be started to drive the rotating shaft 502, the first scraper 503, the stirring rod 504, and the second scraper 505 to rotate, thereby increasing the spraying range of the nozzle 905. This allows for timely cleaning of reactant residues adhering to the stirring mechanism 5, preventing any impact on the normal ratio of reactants for the next preparation of the unblocking acid and ensuring the normal use effect of the unblocking acid.
