Description

Technical Field

[0001] This utility model relates to the field of water injection equipment technology, specifically a water injection equipment for oilfield geological development. Background Technology

[0002] Sub-injection refers to the rational distribution of injected water to different layers. By using layered water distribution tubing (injection pipe and sub-injection pipe) with nozzles of different diameters, water injection is controlled in layers with good permeability and strong water absorption capacity, while water injection is strengthened in oil layers with poor permeability and weak water absorption capacity, so that layers with different permeability can play the role of water injection. In the current process of oilfield geological excavation, well opening is often required, and water injection is often required downhole in oilfield wells. Sub-injection downhole often involves inserting the injection pipe into the ground and connecting it to external water injection pump equipment to carry out water injection work.

[0003] Existing water injection equipment has significant drawbacks in practical applications: (When the water injection pump draws external water and injects it through the injection pipe, the water source is not clean and contains a large amount of solid particulate impurities. These impurities easily enter the pump, causing wear and tear, or enter the injection pipe and clog the nozzles, severely affecting the normal operation of the equipment); Although existing technologies use filter screens to filter solids, the filter screens are easily clogged by impurities during the water injection process, leading to poor water flow; The lack of a reliable self-cleaning and dredging filtration mechanism makes it impossible to maintain effective water flow while ensuring filtration, making it difficult to meet the operational requirements of continuous and stable water injection without shutdown; Therefore, this application proposes a water injection equipment for oilfield geological development to solve the above problems.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 3 As shown in this embodiment, a water injection device for oilfield geological development includes:

[0028] L-shaped support 1, a water pump 101 is fixedly installed on the inner wall of its bottom, the inlet of the water pump 101 is connected to a pipe 102 and the outlet of the water pump 101 is connected to an L-shaped pipe 103.

[0029] The round box 2 is fixedly connected to the rear inner wall of the L-shaped support 1. Its bottom is set as an opening and a sealing plate is fixedly connected to it by four screws. An L-shaped slag discharge pipe 204 is fixedly connected to the bottom left side of the sealing plate, and an L-shaped water inlet pipe is embedded and fixed to the bottom right side of the sealing plate. A water suction hose 104 is fixedly connected to the left end of the L-shaped water inlet pipe. A connecting seat is fixedly connected between the rear side of the round box 2 and the rear inner wall of the L-shaped support 1.

[0030] The circular rotating seat 201 is sealed and movably fitted inside the circular box 2. Water passage holes 202 are provided on both sides of its top. Stainless steel filter screens 203 are fixedly installed inside the water passage holes 202. One end of the guide tube 102 is connected and fixed to the right side of the top of the circular box 2. The water passage hole 202 on the left side is vertically aligned and connected to the L-shaped slag discharge pipe 204, and the water passage hole 202 on the right side is vertically aligned and connected to the L-shaped water inlet pipe and the guide tube 102. The outer side of the circular rotating seat 201 is covered with a sealing rubber sheet, which is in movable contact with the inner wall of the circular box 2 and the top of the sealing plate. Two connecting holes are provided at the top and bottom of the sealing rubber sheet. The through hole is connected to the corresponding water passage hole 202, which serves to achieve a movable seal between the outer side of the circular rotating seat 201 and the inner wall of the circular box 2. The water injection pump 101 is used to draw external water in sequence through the conduit 102, the water passage hole 202 on the right side, the L-shaped water inlet pipe and the water suction hose 104 when it is started, and pump it into the L-shaped pipe 103. The stainless steel filter screen 203 on the right side filters and intercepts solid impurities in the water when the water flows through the water passage hole 202 on the right side, which reduces the phenomenon of a large amount of solid impurities entering the water injection pump 101 and causing internal wear or a large amount entering the subsequent pipes and causing blockage.

[0031] The timing half-turn rotary drive assembly is installed at the bottom of the sealing plate and is fixedly connected to the bottom of the rotary base 201;

[0032] The hydraulic vortex-driven air-blowing cleaning component is embedded and fixed on the top left side of the circular box 2, vertically aligned and connected to the water inlet 202 on the left side, and connected and fixed to the left end of the L-shaped pipe 103. An explosion-proof hose 105 is connected and fixed to the left side of the hydraulic vortex-driven air-blowing cleaning component, and a water injection pipe connector is connected and fixed to the left end of the explosion-proof hose 105. The hydraulic vortex-driven air-blowing cleaning component is used to automatically generate air force using water power when water is supplied through the L-shaped pipe 103, and to back-blow clean and dredge the stainless steel filter screen 203 on the left side, and to pass the supplied water into the explosion-proof hose 105. The water injection pipe connector is used to connect to the external oilfield geological development water injection pipe for water injection. The timed half-turn vortex-driven component is used to drive the circular rotating seat 201 to rotate half a turn at timed intervals. The rotation of the circular rotating seat 201 half a turn drives the two stainless steel filter screens 203 to rotate and change positions for alternating use, forming an alternating filtration and back-blowing cleaning effect.

[0033] Furthermore, such as Figure 2 and 3As shown, the timing half-turn rotary drive assembly includes a servo motor 3 and a PLC controller 301. The servo motor 3 is fixedly installed at the bottom of the sealing plate. The output shaft of the servo motor 3 is fixedly connected to the center of the bottom of the rotary base 201. The servo motor 3 is electrically connected to the PLC controller 301 through wires.

[0034] In this implementation scheme, the servo motor 3 and PLC controller 301 work together. The PLC controller 301 pre-sets the timed start interval of the servo motor 3 according to the on-site cleaning requirements. Based on the pre-calculated number of pulses required for half a revolution, the PLC controller 301 also pre-sets the number of pulses required to start the servo motor 3 each time. For example, if the rotation is 2500 pulses / revolution, then half a revolution requires 1250 pulses. When the cleaning time is reached, the PLC controller 301 controls the servo motor 3 to start rotating half a revolution. The servo motor 3 drives the rotary base 201 to rotate half a revolution, and the rotation of the rotary base 201 drives the two stainless steel filter screens 203 to rotate and change positions. The stainless steel filter screen 203, after being cleaned and unclogged on the left, rotates to the right for filtration, while the stainless steel filter screen 203 originally on the right rotates to the left and is cleaned and unclogged by the downward-blown gas. Under the blowing force, the blown-off impurities are discharged outward through the L-shaped slag discharge pipe 204. When the next cleaning time is reached, it rotates half a turn again for alternating use, and so on, to achieve the effect of automatic alternating filtration and back-blowing cleaning and slag discharge of the two stainless steel filter screens 203. By using the alternating application method, there is no need to stop the machine for cleaning and unclogging, achieving uninterrupted cleaning and application without machine downtime, saving downtime waiting time and improving work efficiency.

[0035] Furthermore, such as Figure 2 and 3 As shown, the hydraulic cyclone-driven air-blowing assembly includes a circular tube 4, multiple air inlet filters 401, a fixed box 402, a rotating shaft 403, multiple water turbine blades 404, and a centrifugal impeller 405. The circular tube 4 is embedded and fixed on the top left side of the circular box 2, and is vertically aligned and connected to the water inlet 202 on the left side. The fixed box 402 is fixedly connected to the top of the circular tube 4. The rotating shaft 403 is sealed and rotatably embedded in the bottom of the fixed box 402. Multiple water turbine blades 404 are fixedly connected to the outside of the rotating shaft 403 in an annular pattern with equal spacing. The left end of the L-shaped tube 103 is connected and fixed to the right side of the fixed box 402, and is horizontally aligned with the rear water turbine blade 404. The explosion-proof hose 105 is connected and fixed to the left side of the fixed box 402. The centrifugal impeller 405 is fixedly connected to the bottom end of the rotating shaft 403 and is located inside the circular tube 4. Multiple air inlet holes are opened in an annular pattern with equal spacing on the top of the outer side of the circular tube 4. Multiple air inlet filters 401 are fixedly installed in the corresponding air inlet holes.

[0036] In this embodiment, a circular through hole is provided at the bottom of the fixed box 402, and two sealed bearings are fixedly fitted inside the circular through hole. A second bearing is fixedly connected to the inner wall of the top of the fixed box 402. The inner ring of the second bearing and the inner ring of the sealed bearing are both fixedly fitted to the outer side of the rotating shaft 403. The sealed bearings provide a sealing effect for the rotating shaft 403. The top left side of the circular box 2 is provided with an insert hole that is fixedly connected to the outer side of the circular tube 4.

[0037] In this embodiment, through the cooperation of the circular pipe 4, multiple air inlet filters 401, fixed box 402, rotating shaft 403, multiple water turbine blades 404, and centrifugal impeller 405, when water is conveyed to the left through the L-shaped pipe 103, it impacts the laterally aligned rear water turbine blades 404. Under the impact of the water, the rear water turbine blades 404 rotate and drive the rotating shaft 403 to rotate. The rotating shaft 403 drives the other multiple water turbine blades 404 to rotate sequentially to the rear and be continuously impacted to provide rotational power, thus realizing the rotational power of the rotating shaft 405 during the water injection process. The 03 unit rotates continuously, with the rotating shaft 403 driving the centrifugal impeller 405 to rotate. When the centrifugal impeller 405 rotates, it draws in external gas through multiple air intake filters 401 and blows it downwards into the water passage 202 on the left side. The downward-blown gas is used to back-blow and clean the stainless steel filter 203 on the left side. The blown-off solid slag and impurities are discharged outwards through the L-shaped slag discharge pipe 204, achieving the effect of automatically generating wind power with water and always back-blowing and cleaning the stainless steel filter 203 on the left side.

[0038] It should be noted that:

[0039] When water is conveyed to the left through the L-shaped pipe 103, it has a large impact force. This impact force impacts the laterally aligned rear water turbine blades 404. Under the impact of the water, the rear water turbine blades 404 rotate and drive the rotating shaft 403 to rotate.

[0040] In addition, when the centrifugal impeller 405 rotates under the drive of the rotating shaft 403, the airflow direction is from top to bottom.

[0041] Furthermore, a lithium battery is fixedly installed on the bottom inner wall of the L-shaped support 1. An inverter is fixed to the rear side of the lithium battery and electrically connected to it via wires. A PLC controller 301 is fixedly installed on top of the lithium battery. The PLC controller 301, the servo motor 3, and the water pump 101 are all electrically connected to the inverter via wires.

[0042] It should be noted that the PLC controller 301 preferably adopts the Siemens S7-200SMART type programmable controller with integrated timing programming control function. The programming control time function of the controller is used to control the servo motor 3 to start at a set time. The corresponding number of start pulses is programmed to control the servo motor 3 to start half a circle each time. The above operations are all conventional applications of programmable controllers. Moreover, this electrical connection method of establishing the control of the PLC controller 301 through direct wire connection is a mature and well-known technology of conventional wire control of controllers, which will not be described in detail here.

[0043] In addition, the inverter is preferably a pure sine wave inverter, and the power standard is selected that the continuous output power of the inverter must be ≥ the rated power of the servo motor 3 + the rated power of the water pump 101 + the rated power of the PLC controller 301. This is the basic principle of power supply for inverter and power supply application, which is a mature and well-known technology, and will not be elaborated here.

[0044] The usage method of this embodiment is as follows: When using the water injection equipment for oilfield geological development, place one end of the suction hose 104 into an external water source or an external water truck, connect the water injection pipe connector at the end of the explosion-proof hose 105 to the external oilfield geological development water injection pipe, start the water injection pump 101, and the water injection pump 101 sequentially draws external water from the external source through the conduit 102, the water inlet 202 on the right side, the L-shaped water inlet pipe, and the suction hose 104, and pumps it into the L-shaped pipe 103. The water then flows through the L-shaped pipe 104... 3. The water is sprayed into the fixed box 402 and then supplied to the external oilfield geological development water injection pipe through the explosion-proof hose 105 for water injection. When the water passes through the water passage 202 on the right side, the stainless steel filter screen 203 on the right side filters and intercepts the solid residue impurities in the water. This achieves the effect of filtering and intercepting the solid residue impurities in the water in advance during water injection, reducing the phenomenon of a large amount of solid residue impurities entering the water injection pump 101 and causing internal wear or a large amount entering the subsequent pipeline and causing blockage, thus improving the safety of use.

[0045] When water is pumped to the left through the L-shaped pipe 103 and sprayed into the fixed box 402, it impacts the laterally aligned rear water impeller 404. Under the impact of the water, the rear water impeller 404 rotates, driving the rotating shaft 403 to rotate. The rotating shaft 403 drives multiple other water impellers 404 to rotate sequentially to be continuously impacted and provided with rotational power, realizing the continuous rotation of the rotating shaft 403 during water injection. The rotating shaft 403 drives the centrifugal impeller 405 to rotate. When the centrifugal impeller 405 rotates, it draws external gas through multiple air intake filters 401 and directs it towards the air intake. The air is blown downwards into the water inlet 202 on the left side, using the downward-blown air to clean and unclog the stainless steel filter screen 203 on the left side. The blown-off solid slag and impurities are discharged outwards through the L-shaped slag discharge pipe 204. The timed start interval of the servo motor 3 is preset using the PLC controller 301 according to the on-site cleaning needs. Based on the pre-calculated number of pulses required for half a revolution, the number of pulses required to start the servo motor 3 each time is preset using the PLC controller 301. For example, if the number of pulses is 2500 pulses / revolution, then half a revolution requires 1250 pulses. When the cleaning time is reached, the PLC controller 301 controls the servo motor 3 to start rotating half a turn. The servo motor 3 drives the rotary base 201 to rotate half a turn. The rotation of the rotary base 201 drives the two stainless steel filter screens 203 to rotate and exchange positions for alternating use. That is, the stainless steel filter screen 203 on the left, after being cleaned and unblocked, rotates to the right for filtration, while the stainless steel filter screen 203 originally on the right rotates to the left for backflushing and cleaning by the downward-blown gas. Under the blowing force, the blown-off impurities are discharged downward through the L-shaped slag discharge pipe 204. When the next cleaning time is reached, the two stainless steel filter screens rotate half a turn again for alternating use, and so on. This achieves the effect of automatic alternating filtration and backflushing cleaning and slag discharge of the two stainless steel filter screens 203 at regular intervals. By using the alternating application method, there is no need to stop the machine for cleaning and unblocking, achieving uninterrupted cleaning and smooth application without machine downtime. This ensures the filtration effect while maintaining effective and continuous water supply, meeting the requirements of continuous and stable water injection without stopping the machine, saving downtime waiting time for cleaning, and improving work efficiency.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
