[0002] Petroleum is a complex mixture, mainly containing different components such as various hydrocarbons, colloids, asphaltenes, etc., which leads to different colors and properties of crude oil. With the continuous development of oil fields, some oil layers with high viscosity and high wax content have become the main production force. Therefore, in the process of oil extraction, it is necessary to inject viscosity reducers into the oil wells to reduce the viscosity of the crude oil, so as to facilitate the extraction of oil in heavy oil wells.

[0003] The existing Chinese patent publication number is CN220451851U, which is a viscosity reducer filling device used in heavy oil wells. It can be seen from the contents recorded in its specification that when the device is in use, it mainly drives the corresponding gears and threaded rods by the forward and reverse rotation of the motor to achieve continuous filling of the viscosity reducer. However, this connection drive structure is relatively complicated, and its production cost is relatively high and inconvenient to promote. In addition, it is very inconvenient to repair and replace the components inside the filling cylinder when they are damaged.

[0004] Therefore, it is necessary to provide a new oil well barrel viscosity reducer filling equipment to solve the above technical problems. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] See also Figures 1 to 5 The embodiment of the utility model provides an oil well barrel viscosity reducer filling device, and the oil well barrel viscosity reducer filling device includes: a bottom plate 1.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 5 A storage tank 2 is provided on one side of the top of the bottom plate 1, and a symmetrically distributed filling cylinder 3 is provided on the other side of the top of the bottom plate 1. A piston plate 5 is provided inside the filling cylinder 3, and a driving assembly 4 is provided outside the filling cylinder 3; the driving assembly 4 includes a support column 41, and the support column 41 is fixedly mounted between the two filling cylinders 3. A rotatably connected driving bar 42 is provided on the top of the support column 41, and rotatably connected transfer bars 421 are provided on both sides of the bottom of the driving bar 42, and the transfer bar 421 is rotatably connected to the piston plate 5; the driving assembly 4 also includes a support block 43, and a rotatably connected cylinder 44 is mounted on one end of the support block 43 and the bottom of the driving bar 42.

[0028] It should be noted that: when in use, the cylinder 44 can be controlled to extend, and the extended cylinder 44 can lift one end of the top driving bar 42. During this process, the driving bar 42 can be rotated with the connection part of the support column 41 as a node, and the end of the driving bar 42 that moves downward can squeeze the piston plate 5 through the corresponding transfer bar 421 below, so that the piston plate 5 can move downward. At this time, the viscosity reducer inside the corresponding filling cylinder 3 can be discharged outward through the filling pipe 32 for filling, and the end of the driving bar 42 that is tilted upward will lift the corresponding transfer bar 421 and the piston plate 5 below. At this time, the suction force generated by the upward movement of the piston plate 5 can suck the viscosity reducer inside the storage tank 2 into the filling cylinder 3 through the liquid inlet pipe 21, so that when the cylinder 44 contracts in the opposite direction, the driving bar 42 can be rotated in the opposite direction, so that the viscosity reducer inside the filling cylinder 3 on the other side can be discharged outward for filling, thereby realizing the cyclic filling of the viscosity reducer;

[0029] By adopting a connecting rod driving method to drive the piston plates 5 on both sides to move up and down inside the filling cylinder 3, this structural linkage structure is simpler and more efficient, thereby reducing the production cost of the device and making it easier to promote.

[0030] In the embodiments of the present invention, please refer to Figures 1 to 5 A fixedly connected positioning frame 52 is provided on the top of the piston plate 5, a positioning block 7 is inserted inside the positioning frame 52, and the top of the positioning block 7 is rotatably connected to the bottom end of the transfer strip 421, a plug hole 521 is opened on the positioning frame 52, and the same slidingly connected limit rod 64 is inserted inside the plug hole 521 and the positioning block 7, a fixedly connected support sheet 6 is provided on the top of the piston plate 5, and a fixedly connected and symmetrically distributed guide rod 61 is provided on the side wall of the support sheet 6 close to the center of the piston plate 5, and a sliding sheet 63 is slidably connected on the side wall of the guide rod 61, and the side wall of the sliding sheet 63 away from the support sheet 6 is fixedly connected to the end of the limit rod 64, and a spring 62 is fixedly installed on the side wall of the support sheet 6 on which the guide rod 61 is provided, and the end of the spring 62 away from the support sheet 6 is fixedly connected to the side wall of the sliding sheet 63 away from the limit rod 64.

[0031] It should be noted that: by adopting the plug-in card connection method, the positioning block 7 and the positioning frame 52 are connected. When the piston plate 5 needs to be disassembled later, the slide 63 can be moved to slide the limit rod 64 out of the positioning block 7 and the positioning frame 52 to release the connection between the positioning block 7 and the positioning frame 52, so that the staff can disassemble the piston plate 5 more conveniently;

[0032] After the limiting rod 64 is inserted into the positioning frame 52 and the positioning block 7, the spring 62 can squeeze the slide 63 through its own force, so that the slide 63 can drive the limiting rod 64, so that the limiting rod 64 can always be stably located in the positioning frame 52 and the positioning block 7, thereby improving the stability of the connection between the two.

[0033] In the embodiments of the present invention, please refer to Figures 1 to 5 A communicating liquid inlet pipe 21 is arranged between the storage tank 2 and the filling cylinder 3, a communicating filling pipe 32 is arranged at the bottom of the filling cylinder 3, both the liquid inlet pipe 21 and the filling pipe 32 are provided with a one-way valve, and the filling pipe 32 is provided with a regulating valve 321.

[0034] It should be noted that: through the setting of the one-way valve, when the piston plate 5 moves to drive the viscosity reducer, the viscosity reducer can be stably extracted from the storage tank 2 and discharged from the filling pipe 32 to the outside, so that the viscosity reducer can flow smoothly as needed.

[0035] In the embodiments of the present invention, please refer to Figures 1 to 5 A guide groove 31 is provided inside the filling cylinder 3, and a fixedly connected guide block 51 is provided on the side wall of the piston plate 5. The outer wall of the guide block 51 abuts against and is slidably connected to the inner wall of the guide groove 31, and rubber rings are sleeved on the side walls of the piston plate 5 and the guide block 51.

[0036] It should be noted that: by arranging rubber rings on the side walls of the piston plate 5 and the guide block 51, when the driving assembly 4 drives the piston plate 5 to move later, the rubber ring can improve the sealing effect between the piston plate 5 and the filling cylinder 3, so that the piston plate 5 can drive the viscosity reducer more stably.

[0037] The working principle of the oil well barrel viscosity reducer filling device provided by the utility model is as follows;

[0038] When using the device, after the device is connected and the viscosity reducer is added, the cylinder 44 in the driving assembly 4 can be controlled to extend and retract, and the extended cylinder 44 can lift one end of the top driving bar 42. During this process, the driving bar 42 can rotate with the connection part with the support column 41 as a node, and the end of the driving bar 42 that moves downward can squeeze the piston plate 5 through the corresponding transfer bar 421 below, so that the piston plate 5 can move downward. At this time, the viscosity reducer inside the corresponding filling cylinder 3 can be discharged outward through the filling pipe 32 for filling;

[0039] The upwardly tilted end of the driving bar 42 will pull the corresponding transfer bar 421 below, so that it drives the corresponding piston plate 5 to slide upward inside the filling cylinder 3. At this time, the suction force generated by the upward movement of the piston plate 5 can suck the viscosity reducer inside the storage tank 2 into the filling cylinder 3 through the liquid inlet pipe 21. When the cylinder 44 contracts in the reverse direction, the driving bar 42 can rotate in the reverse direction, so that the viscosity reducer inside the filling cylinder 3 on the other side can be discharged and filled out, thereby realizing the cyclic filling of the viscosity reducer.

[0040] Later, when the sealing rubber ring on the outside of the piston plate 5 is worn and needs to be replaced, the slide 63 can be moved to drive the limit rod 64 to slide on the outer wall of the guide rod 61 in the direction away from the positioning block 7 until the limit rod 64 slides out from the inside of the positioning block 7. The connection between the positioning block 7 and the positioning frame 52 can be released, thereby releasing the connection between the transfer strip 421 and the piston plate 5, so that the staff can take the piston plate 5 out of the filling cylinder 3 for maintenance and replacement.

[0041] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0042] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
