Description

Technical Field

[0001] The invention relates to an integrated dosing and suppressing device, belonging to the technical field of suppressing equipment. Background Art

[0002] During oilfield production, wellhead dosing is a crucial step in ensuring the normal operation of oil wells and improving oil recovery efficiency. Currently, there are two main methods for dosing oil wellheads: manual dosing and manual dosing pump dosing. However, these traditional dosing methods have the following problems: High labor intensity: Manual dosing of chemicals requires a lot of manpower, the operation is cumbersome, and the labor intensity is high, which can easily lead to operator fatigue and affect work efficiency.

[0003] Uneven dosing flow rate: When adding medicine with a manual dosing pump, due to the instability of human operation, the dosing flow rate is difficult to maintain uniformity, resulting in the inability to fully exert the effect of the medicine and causing waste of medicine.

[0004] Waste of reagents: Due to the uneven dosing flow rate, the reagent cannot be evenly distributed. The concentration of the reagent in some areas is too high, while the concentration in some areas is too low. The expected treatment effect cannot be achieved, resulting in waste of reagents.

[0005] Non-standard operation: The models and sizes of the dosing pumps used in various oil production plants and oil production stations on site are inconsistent, and there is no unified standard for operation, which can easily lead to operational errors, affect the dosing effect, and even cause safety accidents.

[0006] Safety hazards: Due to improper operation, there may be safety hazards during the dosing process, such as drug leakage, equipment damage, etc., which pose potential threats to operators and the environment.

[0007] In addition, at oilfield production sites, freezing or blockage of local processes often occurs due to the influence of process flow or low temperature weather. Conventional unblocking operations use boiler trucks and tank trucks to sweep the line to unblock, but this method has the following problems: Low efficiency: Sweeping and unblocking boiler cars and tank cars requires a lot of equipment and manpower, and the operation is complicated and inefficient, making it impossible to resume production in time.

[0008] High cost: Using boiler cars and tank cars to sweep and unblock lines consumes a lot of fuel and water resources, which is costly and increases production costs.

[0009] When a problem occurs with downhole tubing and further diagnosis is needed, the site often needs to call in a cement truck or tanker to pressure test the tubing to determine the downhole fault. This approach has the following problems: Large equipment: Cement trucks and tankers are large and difficult to move, making them difficult to operate on narrow job sites.

[0010] Complex operation: Using cement trucks and tank trucks to pressurize oil pipelines is complicated and requires professional operators, which increases the difficulty and time cost of operation.

[0011] High cost: The operating costs of cement trucks and tank trucks are high, which increases production costs and is not conducive to improving economic benefits.

[0061] This embodiment provides an improved pressing mechanism. The similarities with embodiment 1 are not described here. The differences from embodiment 1 are as follows: Figure 4 、 Figure 5 The suppressing mechanism includes a suppressing box 81, a drive motor 82, a one-way feed pipe 84, a one-way discharge pipe 83 and a suppressing plate 811. The suppressing plate 811 is slidably and sealedly connected inside the suppressing box 81. The drive motor 82 is arranged on one side of the suppressing box 81 to drive the suppressing plate 811 to axially reciprocate. A rotatable rotating tube 812 is provided inside the suppressing box 81. A plurality of through-type adjustment slots 8121 are provided on the side wall of the rotating tube 812. The inner end of the flow equalizing tube 813 is inserted into the adjustment slot 8121, and the front and rear sides of the flow equalizing tube 813 near the inner end are hinged to the inner wall of the adjustment slot 8121 through a short pin shaft, so that the end of the flow equalizing tube 813 can swing up and down around the axis of the short pin shaft.

[0062] The equalizing flow tube 813 is provided with a plurality of water distribution holes 8131, and the regulating groove 8121 is provided with a sealing ring 8122 with elasticity for sealing. The sealing ring 8122 is sealedly connected to the outer wall of the equalizing flow tube 813, and the one-way feed pipe 84 is connected to the inner cavity of the rotating tube 812. The outlet of the pressure box 81 is provided with a connected one-way discharge pipe 83, and the one-way discharge pipe 83 is connected to the outlet coil.

[0063] The design of the suppression box 81, the suppression plate 811, the one-way feed pipe 84 and the one-way discharge pipe 83 can utilize the reciprocating motion of the suppression plate 811 and the cooperation of the one-way feed pipe 84 and the one-way discharge pipe 83 to realize the pressurized delivery of the medicine by the suppression box 81; and the design of the rotating tube 812, the short pin shaft and the flow equalizing pipe 813 allows the medicine to enter the suppression box 81, and with the rotation of the flow equalizing pipe 813, the liquids of different components can be fully mixed. In this way, when spraying the medicine, the medicine can be fully mixed and then sprayed out, so that the efficacy of the medicine can be fully exerted.

[0064] In this example, see Figure 5 、 Figure 6One end of the rotating tube 812 is rotatably connected to the inner wall of the pressure box 81, and a driving mechanism for driving the rotating tube 812 to rotate is provided in the pressure box 81. A rotatable positioning rod 815 is provided in the rotating tube 812. The outer circumference of the positioning rod 815 is provided with a reciprocating thread 8151. The outer surface of the positioning rod 815 is covered with a matching positioning inner sleeve 8152, and the positioning inner sleeve 8152 and the positioning rod 815 are connected by the reciprocating thread 8151. A guide rod 8155 is provided in the rotating tube 812 and fixedly connected to the bottom wall of the pressure box 81. The guide rod 8155 slides through the positioning inner sleeve 8152, so that the positioning inner sleeve 8152 can only move axially. A rotatably connected positioning outer sleeve 8154 is provided on the outside of the positioning inner sleeve 8152. Multiple rotatably connected telescopic rods 8153 are provided on the outside of the positioning outer sleeve 8154. The ends of the telescopic rods 8153 are rotatably connected to the ends of the flow equalizing tube 813. A first hole is provided on the bottom wall of the pressure box 81, which communicates with the inner cavity of the rotating tube 812. A one-way feed pipe 84 is connected to the first hole. Two one-way feed pipes 84 are provided: one for the reagent and the other for the water.

[0065] Through the rotation of the positioning rod 815, in conjunction with the reciprocating thread 8151, and the limiting of the guide rod 8155, the positioning inner sleeve 8152 can periodically reciprocate up and down along the positioning rod 815, and coupled with the traction of the telescopic rod 8153, the flow equalizing tube 813 can rotate with the rotating tube 812 while also swinging up and down around the short pin shaft, so that the flow equalizing tube 813 can mix the medicine in the pressure box 81 more fully.

[0066] In this example, see Figure 5 The flow equalizing tube 813 is provided with a slidingly connected cleaning ring plate 8132, and the end of the flow equalizing tube 813 is provided with a baffle to prevent the cleaning ring plate 8132 from slipping. A cleaning brush is provided on the inner wall of the cleaning ring plate 8132 for cleaning the water distribution hole 8131. The cleaning ring plate 8132 is made of a plate with a certain weight. The design of the cleaning ring plate 8132 enables the flow equalizing tube 813 to swing up and down around the short pin shaft. Under the action of gravity, the cleaning ring plate 8132 can move back and forth along the flow equalizing tube 813, effectively preventing impurities from staying on the flow equalizing tube 813, and can also clean the water distribution hole 8131 to prevent the water distribution hole 8131 from being blocked.

[0067] In this example, see Figure 4 The output end of the drive motor 82 is provided with a fixedly connected drive disc 821, and a connecting rod 822 is hinged on the drive disc 821. The other end of the connecting rod 822 is hinged to the pressing plate 811. The drive motor 82 rotates the drive disc 821, and one end of the connecting rod 822 follows the drive disc 821 to make a circular motion, while the other end of the connecting rod 822 drives the pressing plate 811 to make a periodic reciprocating motion.

[0068] In this example, see Figure 5 The root periphery of the rotating tube 812 is covered with an annular cylinder 814, the top wall center of the annular cylinder 814 can be rotatably supported on the outer wall of the rotating tube 812 and sealed with each other, the lower port of the annular cylinder 814 can be rotatably embedded in the bottom wall groove of the pressure box 81 and sealed with each other, the outer peripheral wall of the annular cylinder 814 is provided with a plurality of discharge pipes 8142 connected with its inner cavity, and the discharge pipe 8142 is provided with a plurality of discharge holes 8141, and the pressure box 81 is provided with a second hole connected with the inner cavity of the annular cylinder 814, and the outer side of the second hole is connected with the one-way discharge pipe 83.

[0069] In this example, see Figure 5 、 Figure 7 The driving mechanism includes a driving rod 816, a first spiral rod 8161 and a first driving ring 8162. One end of the driving rod 816 is fixedly installed in the center of the pressing plate 811. One end of the rotating tube 812 is provided with a driving groove 8165 that is slidably and sealedly connected to the driving rod 816. The inner wall of the driving groove 8165 is provided with a first limiting ring groove connected to the first driving ring 8162. The end of the driving rod 816 is provided with a spiral first spiral rod 8161. The first spiral rod 8161 is matched with the first driving ring 8162. When the first spiral rod 8161 passes through the first driving ring 8162, it drives the first driving ring 8162 to rotate.

[0070] By utilizing the spiral characteristics, the driving rod 816 can drive the first driving ring 8162 and thus the rotating tube 812 to continuously rotate forward and reverse as it follows the axial movement of the pressing plate 811. The spiral design adopts the spiral design of the existing hand-propelled bamboo dragonfly, which is existing technology and will not be described in detail in this application. Example

[0071] This embodiment is a further optimization based on embodiment 2. Figure 5 、 Figure 7 The driving groove 8165 extends downward to the center of the end of the positioning rod 815. A second limiting ring groove is provided at the end of the driving groove 8165 in the positioning rod 815. A second driving ring 8164 with a one-way rotation connection is provided in the second limiting ring groove. A spiral second screw rod 8163 is provided at the end of the first screw rod 8161. The second screw rod 8163 is matched with the second driving ring 8164 and is connected. When the second screw rod 8163 passes through the second driving ring 8164, the second driving ring 8164 is rotated.

[0072] The design of the second drive ring 8164 and the second spiral rod 8163, as well as the one-way rotation connection between the second drive ring 8164 plate and the second limiting ring groove, enables the drive rod 816 to push the second drive ring 8164 to rotate while driving the positioning rod 815 to rotate synchronously during the downward movement; and when the drive rod 816 moves upward, it pushes the second drive ring 8164 to rotate in the opposite direction. At this time, the second drive ring 8164 will not drive the positioning rod 815 to rotate. This design can enable the positioning rod 815 to continue to rotate in the same direction, and can enable the positioning rod 815 to periodically drive the positioning inner sleeve 8152 to move up and down.

[0073] In this example, see Figure 8 An outer gear ring 8123 is fixed to the outer wall of the rotating tube 812, which is located within the inner cavity of the annular cylinder 814. An inner gear ring 8143 is fixed to the inner circumferential wall of the annular cylinder 814. The outer gear ring 8123 and the inner gear ring 8143 are meshed via an intermediate gear 8144. Specifically, one side of the intermediate gear 8144 meshes with the outer gear ring 8123 and the other side meshes with the inner gear ring 8143. The outer gear ring 8123, intermediate gear 8144, and inner gear ring 8143 are all located within the inner cavity of the annular cylinder 814. The design of the outer gear ring 8123, intermediate gear 8144, and inner gear ring 8143 ensures that the flow-equalizing tube 813 and the discharge tube 8142 rotate in opposite directions. This design ensures more thorough mixing of the liquid medicine within the pressure chamber 81.

[0074] When using this device: When spraying medicine, connect the outer end of the one-way feed pipe 84 to the corresponding medicine barrel and clean water barrel, then start the drive motor 82 to drive the pressure plate 811 to move back and forth periodically. Through the reciprocating motion of the pressure plate 811, in conjunction with the one-way feed pipe 84 and the one-way valve in the one-way discharge pipe 83, the materials in the medicine barrel and the clean water barrel can be automatically sucked into the one-way feed pipe, and then enter the inner cavity of the rotating tube 812, enter the inner cavity of the flow equalizing tube 813 through the rotating tube 812, and then enter the pressure box 81 through each water distribution hole 8131, and finally enter the discharge pipe 8142 through the discharge hole 8141, enter the one-way discharge pipe 83 through the discharge pipe 8142 and be discharged, and then be sprayed normally through the outlet coil.

[0075] During the reciprocating motion of the pressing plate 811, the pressing plate 811 can drive the driving rod 816 to synchronously perform axial periodic reciprocating motion. The periodic reciprocating motion of the driving rod 816 can drive the first driving ring 8162 to rotate periodically forward and reverse through the first spiral rod 8161, so that the rotating tube 812 can periodically rotate forward and reverse during the process of the medicine entering the pressing box 81, so that the equalizing flow tube 813 can stir and mix the medicine entering the pressing box 81. At the same time, through the meshing transmission of the outer ring gear 8123, the intermediate gear 8144 and the inner ring gear 8143, the discharge pipe 8142 can synchronously rotate forward and reverse periodically, and the rotation direction of the equalizing flow tube 813 is opposite to that of the discharge pipe 8142, which can better mix the medicine.

[0076] At the same time, the periodic reciprocating motion of the driving rod 816 can also synchronously drive the second driving ring 8164 to rotate forward and backward periodically through the second screw rod 8163. Since the second driving ring 8164 and the second limiting ring groove are connected in a one-way rotation, the second driving ring 8164 will only drive the positioning rod 815 to always rotate in the same direction. In this way, under the action of the reciprocating thread 8151 and due to the limitation of the guide rod 8155, the positioning inner sleeve 8152 can periodically reciprocate up and down, thereby driving the end of the equalizing flow tube 813 to swing up and down, which can further improve the mixing efficiency of the medicine and facilitate the cleaning of the outer wall of the equalizing flow tube 813.
