Description

Technical Field

[0001] The utility model relates to the technical field of oil well dosing, in particular to a multi-channel dosing device for accompanying injection and matching. Background Art

[0002] An oil well is a hole drilled by drilling methods. Generally, after reaching the oil layer, an oil well casing is lowered, and oil well cement is injected into the annular space between the casing and the well wall to maintain the well wall and seal the oil, gas and water layers. Later, according to the requirements of oil field development, a perforating gun is used to open the oil layer to form a channel, and an oil pipe is lowered. Using appropriate inducing flow methods, the oil is raised from the bottom of the oil well to the wellhead. Adding chemicals to oil wells is one of the daily tasks of oil producers. Its purpose is to prevent wax deposition in oil wells and oil pipelines and extend the maintenance-free period of oil wells.

[0003] In certain field applications, such as when it is necessary to prepare the drug solution on site and then perform drug dosing operations on the oil well, the design limitations of the existing drug dosing devices become particularly obvious. Most drug dosing devices are only equipped with a single feed channel, which means that in the process of preparing the drug solution, drug powder and water cannot be added to the device at the same time, and must be done step by step, first adding drug powder and then adding water, or vice versa. This sequential operation not only prolongs the drug solution preparation time, but may also affect the uniformity of drug solution mixing. In addition, when it comes to accurate quantitative dosing of oil wells, existing devices often rely on manual operation and lack automated metering and control mechanisms, making it difficult to achieve true quantitative dosing.

[0004] Therefore, a multi-channel dosing device for accompanying injection is particularly needed to solve the problems existing in the prior art. Utility Model Content

[0005] In order to overcome the shortcomings of the existing dosing device that not only prolongs the preparation time of the drug solution, but also may affect the uniformity of the mixing of the drug solution, and it is difficult to achieve true quantitative dosing, the utility model provides a multi-channel dosing device for concomitant injection.

The silicone block is connected to the edge of the stirring rod. At least one through hole is opened at the lower end of the cylinder of the stirring rod. The pipette is located inside the stirring rod with the lower end close to the through hole.

[0011] In one embodiment, two semi-annular collecting boxes form a ring to surround the lifting block, so that the sediment on the surface of the lifting block and the inclined block slides into the receiving groove of the collecting box.

A solenoid valve 12 for controlling the discharge is connected inside the single channel 13 by bolts. A symmetrically distributed semi-annular collecting box 16 is connected to the lower part of the shell 1 by bolts. A circular groove is formed between the two collecting boxes 16 to encircle the electric push rod 15. The two semi-annular collecting boxes 16 form a ring to surround the lifting block 14, so that the sediment on the surface of the lifting block 14 and the inclined block 8 slides into the storage groove of the collecting box 16. A liquid outlet 17 connected to the storage groove is connected to the bottom of the collecting box 16, and a filter is arranged inside the liquid outlet 17. A pressure barrel 19 is connected to the single channel 13 by bolts on the upper right side of the shell 1. The pressure barrel 19 is connected to the single channel 13 and is operated by the metering pump 11, so that the medicine inside the shell 1 is sucked into the suction tube 9 and the circular frame 901 in turn, and then the medicine is pumped into the single channel 13.

[0028] See also Figure 1-Figure 3As shown, it also includes a motor 3, a small gear 4, a large gear 5, a stirring rod 6 and a silicone block 601. The motor 3 is connected to the left side of the top of the shell 1 by bolts. The output shaft of the motor 3 penetrates into the inside of the shell 1 and is connected to the small gear 4 by welding. The top of the shell 1 is rotatably connected to the large gear 5. The small gear 4 and the large gear 5 are on the same horizontal plane and mesh with each other. The stirring rod 6 is connected to the center position of the large gear 5 by welding. The stirring rod 6 is composed of a hollow cylinder and four E-shaped plates fixedly connected. The stirring rod 6 is close to the inner wall of the shell 1 (when stirring the powder and water) When the stirring rod 6 is in contact with the inner wall of the shell 1, the lifting block 14 and the inclined block 8, the residual powder on the inner wall of the shell 1 can be scraped off without affecting the normal movement of the stirring rod 6), and a silicone block (601) is connected to the edge where the stirring rod 6 contacts the inner wall of the shell 1, the lifting block 14 and the inclined block 8 to prevent the stirring rod 6 from wearing the inner wall of the shell 1, the lifting block 14 and the inclined block 8. At least one through hole 7 is opened at the lower end of the cylinder of the stirring rod 6, and the pipette 9 is located inside the stirring rod 6 and the lower end is close to the through hole 7. The small gear 4 is rotated by the operation of the motor 3 to mesh with the large gear 5, so that the large gear 5 drives the stirring rod 6 to rotate.

[0029] See also Figure 1 As shown, a controller 18 is also included. The front side of the housing 1 is connected to the controller 18 by bolts. The controller 18 is electrically connected to the motor 3, the metering pump 11, the solenoid valve 12, the electric push rod 15 and the pressure barrel 19.

[0030] First, the staff sets the threshold of the metering pump 11 according to the dosing demand of the oil well, and then adds the powder and water into the housing 1 from the multi-channel drug inlet 2 at the same time. Then, the motor 3 is turned on through the controller 18. The output shaft of the motor 3 rotates to drive the small gear 4 to rotate and mesh with the large gear 5, and then the large gear 5 drives the stirring rod 6 to rotate to fully mix the powder and water to obtain the liquid medicine, so that the liquid medicine can be prepared at any time. During the mixing, the liquid medicine flows from the through hole 7 into the cylinder of the stirring rod 6. During the mixing process, sediment will be generated and precipitated on the surface of the lifting block 14 and the inclined block 8. When the stirring rod 6 rotates, it scrapes the lifting block 14 and the sediment on the surface of the inclined block 8, thereby preventing the sediment from sticking to the lifting block 14 and the surface of the inclined block 8, and then connecting the prepared dosing pipe with the single channel 13, and then connecting the connected dosing pipe with the pipeline of the oil well. After the connection is completed, start the metering pump 11, and at the same time control the solenoid valve 12 to open the single channel 13. The metering pump 11 runs to suck the liquid in the cylinder of the stirring rod 6 into the suction pipe 9 and the circular frame 901 in turn. After the liquid flows into the circular frame 901, it impacts the impeller 10 to rotate, thereby causing the impeller 10 to flip the liquid for re-mixing. The metering pump 11 continues to run to pass through the impeller 10 The turned medicine liquid is pumped into the single channel 13, and the medicine liquid in the single channel 13 flows from the medicine adding pipe into the pipeline of the oil well for medicine adding. During the medicine adding process, the pressure barrel 19 is opened in advance to balance the water volume and increase the water pressure of the medicine liquid, so that the medicine liquid can be better delivered to the well. When the medicine liquid delivered by the metering pump 11 reaches its set threshold, the metering pump 11 stops running immediately, thereby achieving the purpose of quantitative medicine adding, reducing human errors, ensuring that each medicine adding can reach the expected dosage, and improving the reliability and efficiency of the operation. Then the motor 3 and the pressure barrel 19 are turned off, and the solenoid valve 12 is controlled to close the single channel. 13, and then turn on the electric push rod 15, control the telescopic rod of the electric push rod 15 to retract to the limit, so that the lifting block 14 moves downward and breaks contact with the inner wall of the shell 1. After breaking contact, there is a gap between the lifting block 14 and the shell 1, and the sediment scraped by the stirring rod 6 on the surface of the lifting block 14 and the inclined block 8 automatically slides into the collecting box 16 through the gap, thereby realizing the cleaning and collection of the sediment. During the collection, the residual liquid in the sediment is discharged from the liquid outlet 17, thereby realizing solid-liquid separation. When it is necessary to clean the solid residue in the collecting box 16, the collecting box 16 can be directly removed from the shell.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
