Description

Technical Field

[0001] The invention relates to the technical field of acid preparation, and in particular to a precisely controlled automatic acid preparation device. Background Art

[0002] Internal acid treatment is to inject hydrochloric acid, mud acid (mixture of hydrofluoric acid and hydrochloric acid) or other acid solutions into the formation with the help of acid fracturing equipment, expand the permeability channel of the oil layer rock through the dissolution of the acid on the rock, dissolve the blockage in the seepage channel or create artificial cracks, so that the oil and gas channels are unblocked, so as to achieve the purpose of increasing oil and gas production; Acidizing is one of the measures to increase the production of carbonate and sandstone oil and gas reservoirs. In 1933, Halliburton Company first injected a mixture of hydrofluoric acid and hydrochloric acid into the well. However, this initiative was not successful due to the limitations of the technical conditions at the time. It was not until the mid-1950s that the mixture of these two acids was successfully used in industry after repeated practice. The successful application of mud acid has greatly promoted the development of acidizing technology, and some companies that were established to provide acidizing services have greatly accelerated the development of acidizing technology. After more than 100 years of development, acidizing treatment technology has become one of the main measures to increase the production of oil and gas wells and increase the injection of water injection wells; When preparing acid in a well, water and concentrated hydrochloric acid need to be poured in and mixed to prepare hydrochloric acid of a specific concentration. Because particles that can react with acid may be attached to the water and the pipes used to pour water, these objects flow into the acid preparation container with the water flow, which may cause the acid concentration to be too low or even cause an explosion. Therefore, the required water needs to be pretreated before preparing the acid to meet the requirements for safe acid preparation. Summary of the invention

[0013] The beneficial effects of the present invention are as follows: The present invention sets an acid storage mechanism. Before pouring high-concentration hydrochloric acid into the acid preparation cylinder, the concentrated hydrochloric acid will first enter the buffer box. The baffle plate 1 will weaken the kinetic energy of the concentrated hydrochloric acid when it is input, so that the concentrated hydrochloric acid slowly enters the acid preparation cylinder along the acid outlet pipe to prevent the flow speed from being too fast and causing splashing. The present invention sets a water storage mechanism. The water flows into the water storage tank along the water inlet pipe. The descaling mechanism will start working first. The filter plate will first separate some granular impurities in the water to avoid the reaction between the impurity particles and the hydrochloric acid. As the water level in the water storage tank rises, the airbag will drive the sliding plate 2 to move upward along the side groove and drive the support plate 1 to move upward. After that, as the water flows into the acid preparation cylinder, the water level will drop, and the support plate 1 will move downward again. At the same time, due to the action of the sliding plate 1 and the fixed rod on the inclined plate, the scraping force generated by the scraping plate and the filter plate becomes larger, and the particles attached to the filter plate are scraped off into the dirty storage plate. The dirty storage plate can be disassembled at regular intervals to pour out the impurities collected in the dirty storage plate. The present invention sets a knocking mechanism. Due to the presence of air in the floating plate, the buoyancy generated will make the pressing plates on both sides in a horizontal state. When the support plate drives the scratch plate to move downward, the scratch plate will come into contact with the pressing plate on one side, so that the rotating shaft rotates, and then drives the knocking rod on the other side to collide with the top of the scratch plate, so that some impurities attached to the bottom of the scratch plate fall off, improving the cleaning effect of the subsequent scratch plate. The present invention sets an exhaust mechanism. After water and concentrated hydrochloric acid come into contact, some harmful gases such as chlorine will be generated. These gases will enter the absorption bin through the steam pipe to react with the ferric chloride in the absorption bin, thereby absorbing the generated harmful gases. The present invention is provided with a pressure dividing mechanism. Since the contact between concentrated hydrochloric acid and water will generate a large amount of heat, the pressure in the device will increase. When the pressure is too high, the trachea will rupture, which will cause the dangerous gas to be unable to be absorbed. At this time, the increased air pressure will push the sealing block to move upward, so that the harmful gas enters the absorption bin through the support pipe. At the same time, as the sealing block moves upward, the holding plate will also be lifted along with the support rod, thereby bringing up a part of the ferric chloride solution, and then the solution will flow downward through the leakage port, thereby increasing the contact between the gas and the solution and increasing the absorption efficiency. The present invention is provided with an absorption mechanism. After descaling the water, the water will contact the nanofiltration membrane layer, and the nanofiltration membrane layer will adsorb the calcium and magnesium ions in the water. After these ions enter the acid preparation cylinder, the contact between the acid and water will generate high temperature. After a long time, the calcium and magnesium ions will form scale, and these scales will combine with the hydrogen ions in the hydrochloric acid, thereby changing the concentration of the hydrochloric acid.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses. Example 1, using Figure 1-Figure 10 A precision-controlled automated acid preparation device according to one embodiment of the present invention is described as follows.

[0025] like Figure 1-Figure 10 As shown, a precision-controlled automatic acid preparation device of the present invention comprises: An acid preparation cylinder 1, and fixed support legs 2 evenly arranged at the bottom of the acid preparation cylinder 1, the top of the support legs 2 is fixedly connected to the bottom of the acid preparation cylinder 1, an acid storage mechanism 4 is fixedly connected to the outer surface of the acid preparation cylinder 1, and an acid outlet pipe 6 is evenly arranged on the inner wall of the acid preparation cylinder 1, and the outer surface of the acid outlet pipe 6 is fixedly connected to the inner wall of the acid preparation cylinder 1; A water storage mechanism 3, which is used to purify water required for acid preparation; An exhaust mechanism 5, which is used to purify the toxic gas generated by acid preparation; When a precisely controlled automatic acid preparation device is working, water is first poured into the water storage mechanism 3, and then the water treated by the water storage mechanism 3 will first flow into the acid preparation cylinder 1, and then concentrated hydrochloric acid is poured into the acid storage mechanism 4, and the concentrated hydrochloric acid and water are mixed to prepare hydrochloric acid of the required concentration. At the same time, the harmful gases generated during the acid preparation process will enter the exhaust gas mechanism 5 to be absorbed and purified.

[0026] like Figure 4 As shown, the water storage mechanism 3 includes a water outlet pipe 31, one end of the water outlet pipe 31 away from the acid preparation cylinder 1 is fixedly connected to a water storage tank 32, one end of the water storage tank 32 away from the water outlet pipe 31 is fixedly connected to a water inlet pipe 33, the bottom of the water storage tank 32 is fixedly connected to a dirt storage plate 34, the dirt storage plate 34 is connected to the water storage tank 32 by threads, the inner wall of the water storage tank 32 is fixedly connected to an inclined plate 35, the inner wall of the inclined plate 35 is slidably connected to a sliding plate 38, the outer surface of the sliding plate 38 is fixedly connected to a fixing rod 39, the outer surface of the inclined plate 35 is fixedly connected to an absorption mechanism 36, and the end of the inclined plate 35 away from the absorption mechanism 36 is provided with a descaling mechanism 37; First, untreated water is poured into the water storage tank 32 through the water inlet pipe 33, the descaling mechanism 37 will start to work first, the inclined plate 35 will withstand the strong water flow at the beginning, and then the absorption mechanism 36 will also start to work.

[0027] like Figure 8As shown, the absorption mechanism 36 includes a spreading rod 361 , a nanofiltration membrane layer 362 is slidably connected to the outer surface of the spreading rod 361 , and a fixing ring 363 is fixedly connected to the outer surface of the spreading rod 361 .

[0028] After descaling the water, the water will come into contact with the nanofiltration membrane layer 362, which will adsorb the calcium and magnesium ions in the water. After these ions enter the acid preparation cylinder 1, the contact between the acid and water will generate high temperature, and the calcium and magnesium ions will form scale after a long time. These scales will combine with the hydrogen ions in the hydrochloric acid, thereby changing the concentration of the hydrochloric acid. The propping rod 361 will prop up the nanofiltration membrane layer 362 to prevent the water flow from impacting and deforming the nanofiltration membrane layer, thereby weakening the effect of absorbing ions.

[0029] The outer surface of the water outlet pipe 31 is fixedly connected to the inner wall of the acid preparation cylinder 1 , the outer surface of the expansion rod 361 is fixedly connected to the outer surface of the inclined plate 35 , and the end of the expansion rod 361 away from the inclined plate 35 is fixedly connected to the inner wall of the water storage tank 32 .

[0030] like Figure 5-Figure 6 As shown, the descaling mechanism 37 includes a filter plate 371, the surface of the filter plate 371 is evenly provided with filter holes 372, both ends of the filter plate 371 are symmetrically provided with side grooves 373, the outer surface of the filter plate 371 is evenly provided with a knocking mechanism 374, the inner wall of the side groove 373 is slidably connected with a sliding plate 2 375, the top of the sliding plate 2 375 is fixedly connected with a support rod 1 376, the top of the support rod 1 376 is fixedly connected with a support plate 1 377, the end of the support plate 1 377 close to the filter plate 371 is fixedly connected with a scratch plate 378, and the outer surface of the sliding plate 2 375 is fixedly connected with an air bag 379.

[0031] When the descaling mechanism 37 starts to work, the filter plate 371 will first separate some particulate impurities in the water to prevent the impurity particles from reacting with hydrochloric acid. As the water level in the water storage tank 32 rises, the air bag 379 will drive the sliding plate 2 375 to move upward along the side groove 373, and drive the support plate 1 377 to move upward. Then, as the water flows into the acid preparation cylinder 1, the water level will drop, causing the support plate 1 377 to move downward again. At the same time, due to the action of the sliding plate 1 38 and the fixing rod 39 on the inclined plate 35, the distance between the sliding plate 1 38 and the filter plate 371 will become farther when the sliding plate 1 38 moves downward, so that the scraping force generated by the scraping plate 378 and the filter plate 371 becomes larger, thereby scraping the particles attached to the filter plate 371 into the dirt storage plate 34. The impurities collected in the dirt storage plate 34 can be poured out by disassembling the dirt storage plate 34 at regular intervals.

[0032] The outer surface of the filter plate 371 is fixedly connected to the inner wall of the water storage tank 32, and the end of the sliding plate 2 375 away from the air bag 379 is fixedly connected to the end of the fixing rod 39 away from the sliding plate 1 38.

[0033] like Figure 7 As shown, the knocking mechanism 374 includes a knocking notch 3741, the inner wall of the knocking notch 3741 is rotatably connected to a rotating shaft 3742, the outer surface of the rotating shaft 3742 is symmetrically provided with a pressing plate 3743, the bottom of the pressing plate 3743 is fixedly connected to a floating plate 3744, and a knocking rod 3745 is fixedly connected to the surface of the pressing plate 3743 on one side.

[0034] Due to the presence of air in the floating plate 3744, the buoyancy generated will make the pressing plates 3743 on both sides in a horizontal state. In the process of the support plate 377 driving the scratch plate 378 to move downward, the scratch plate 378 will come into contact with the pressing plate 3743 on one side, thereby causing the rotating shaft 3742 to rotate, and then drive the knocking rod 3745 on the other side to collide with the top of the scratch plate 378, so that some impurities attached to the bottom of the scratch plate 378 fall off, thereby improving the subsequent cleaning effect of the scratch plate 378.

[0035] like Figure 3 As shown, the acid storage mechanism 4 includes a buffer box 41, the inner wall of the buffer box 41 is fixedly connected to a baffle 42, the outer surface of the buffer box 41 is fixedly connected to an acid inlet pipe 43, and an acid outlet 44 is provided on the side of the buffer box 41 away from the acid inlet pipe 43.

[0036] Before pouring high concentration hydrochloric acid into the acid preparation cylinder 1, the concentrated hydrochloric acid will first enter the buffer box 41, and the baffle 1 42 will weaken the kinetic energy of the concentrated hydrochloric acid during input, so that the concentrated hydrochloric acid slowly enters the acid preparation cylinder 1 along the acid outlet pipe 6 to prevent splashing caused by excessive flow speed.

[0037] One end of the buffer box 41 close to the acid outlet 44 is fixedly connected to the outer surface of the acid preparation cylinder 1 , and the acid outlet 44 is tightly fitted to the acid outlet pipe 6 .

[0038] The specific workflow is as follows: When working, first pour untreated water into the water storage mechanism 3, and the water flows into the water storage tank 32 along the water inlet pipe 33. The descaling mechanism 37 will start working first, and the filter plate 371 will first separate some granular impurities in the water to prevent the impurity particles from reacting with hydrochloric acid. As the water level in the water storage tank 32 rises, the air bag 379 will drive the sliding plate 2 375 to move upward along the side groove 373, and drive the support plate 1 377 to move upward. After that, as the water flows into the acid preparation cylinder 1, the water level will drop, thereby causing the support plate 1 377 to move upward. The support plate 377 moves downward again. At the same time, due to the action of the sliding plate 38 and the fixing rod 39 on the inclined plate 35, the scraping force generated by the scraping plate 378 and the filter plate 371 becomes larger, thereby scraping the particles attached to the filter plate 371 into the dirt storage plate 34. The dirt storage plate 34 can be removed at regular intervals to pour out the impurities collected in the dirt storage plate 34. After that, due to the presence of air in the floating plate 3744, the buoyancy generated will make the pressing plates 3743 on both sides in a horizontal state. In the process of the support plate 377 driving the scraping plate 378 to move downward, the scraping plate 378 is 78 will come into contact with the pressing plate 3743 on one side, so that the rotating shaft 3742 will rotate, and then drive the knocking rod 3745 on the other side to collide with the top of the scratching plate 378, so that some impurities attached to the bottom of the scratching plate 378 will fall off, improving the cleaning effect of the subsequent scratching plate 378, and then the absorption mechanism 36 starts to work. After descaling the water, the water will come into contact with the nanofiltration membrane layer 362, and the nanofiltration membrane layer 362 will absorb the calcium and magnesium ions in the water. After these ions enter the acid preparation cylinder 1, they will produce high Temperature, calcium and magnesium ions will form scale after a long time, and these scales will combine with hydrogen ions in hydrochloric acid, thereby changing the concentration of hydrochloric acid, and the water after some treatment will enter the acid preparation cylinder 1 through the water outlet pipe 31, and then enter the water storage mechanism through the acid inlet pipe 43, and the concentrated hydrochloric acid will first enter the buffer tank 41, and the baffle 42 will weaken the kinetic energy of the concentrated hydrochloric acid during input, so that the concentrated hydrochloric acid will slowly enter the acid preparation cylinder 1 along the acid outlet pipe 6 to prevent sputtering caused by excessive flow speed, and then the concentrated hydrochloric acid and water will be mixed in the acid preparation cylinder 1 to prepare hydrochloric acid of required concentration.

[0039] Embodiment 2, use Figure 1-Figure 10 A precision-controlled automated acid preparation device according to one embodiment of the present invention is described as follows.

[0040] like Figure 9-10As shown, a precisely controlled automated acid preparation device of the present invention is based on the first embodiment, and the exhaust mechanism 5 includes a support pipe 51, the top of the support pipe 51 is fixedly connected with an absorption bin 52, the top of the absorption bin 52 is provided with a sealing cover 53, and the sealing cover 53 is connected by threads to facilitate subsequent disassembly, the bottom of the absorption bin 52 is fixedly connected with a partition plate 54, the inner wall of the partition plate 54 is provided with a pressure dividing mechanism 55, the outer surface of the absorption bin 52 is evenly provided with air pipes 56, the top of the air pipes 56 is fixedly connected to the outer surface of the absorption bin 52, and the bottom of the air pipes 56 is fixedly connected to the outer surface of the acid preparation cylinder 1.

[0041] Before the exhaust mechanism 5 works, the sealing cover 53 is opened and ferric chloride solution is poured into the space between the partition plate 54 and the absorption bin 52. When water and concentrated hydrochloric acid come into contact, some harmful gases such as chlorine will be generated. These gases will enter the absorption bin 52 through the steam pipe and react with the ferric chloride in the absorption bin 52, thereby absorbing the generated harmful gases.

[0042] like Fig.10 As shown, the pressure dividing mechanism 55 includes a second support rod 551, the bottom of the second support rod 551 is fixedly connected to a second support plate 552, the top of the second support plate 552 is fixedly connected to a telescopic spring 553, the top of the telescopic spring 553 is fixedly connected to a sealing block 554, the top of the sealing block 554 is evenly provided with a third support rod 555, the bottom of the third support rod 555 is fixedly connected to the top of the sealing block 554, the bottom of the third support rod 555 is fixedly connected to a containing plate 556, and the bottom of the containing plate 556 is provided with a liquid leakage port 557.

[0043] Since concentrated hydrochloric acid and water generate a large amount of heat when in contact, the pressure in the device will increase. When the pressure is too high, the air pipe 56 will rupture, which will make the dangerous gas unable to be absorbed. At this time, the increased air pressure will push the sealing block 554 to move upward, allowing the harmful gas to enter the absorption bin 52 through the support tube 51. At the same time, as the sealing block 554 moves upward, the containing plate 556 will also be lifted up along with the support rod, thereby bringing up a part of the ferric chloride solution. The solution will then flow downward through the leakage port 557, thereby increasing the contact between the gas and the solution and increasing the absorption efficiency.

[0044] The top of the second support rod 551 is fixedly connected to the inner wall of the acid preparation cylinder 1 , and the bottom of the support tube 51 is fixedly connected to the top of the acid preparation cylinder 1 .

[0045] The specific workflow is as follows: During operation, first open the sealing cover 53, and pour the ferric chloride solution into the space between the partition plate 54 and the absorption bin 52. After the contact between water and concentrated hydrochloric acid, some harmful gases such as chlorine will be generated. These gases will enter the absorption bin 52 through the steam pipe and react with the ferric chloride in the absorption bin 52, thereby absorbing the generated harmful gases. When the pressure in the acid preparation cylinder 1 is too high, the increased air pressure will push the sealing block 554 to move upward, so that the harmful gas enters the absorption bin 52 through the support tube 51. At the same time, as the sealing block 554 moves upward, the containing plate 556 will also be lifted up along with the support rod, thereby bringing up a part of the ferric chloride solution, and then the solution will flow downward through the leakage port 557, thereby increasing the contact between the gas and the solution and increasing the absorption efficiency.

[0046] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
