Description

Technical Field

[0001] The utility model relates to the technical field of injection pumps, in particular to an injection pump for oilfield water injection. Background Art

[0002] During the continuous exploitation of the oilfield, the formation pressure will continuously decrease, a large amount of underground crude oil will degas, the viscosity will increase, and the oil well production will be greatly reduced. In order to ensure the normal exploitation of the oilfield, it is necessary to carry out water injection operations on the oilfield through an injection pump device to ensure the formation pressure.

[0003] At present, when the injection pump is working, the pump body will generate relatively large noise, which will have a greater impact on the operators who are exposed to this environment for a long time; secondly, the outlet pressure of the injection pump is relatively high, and fluid impact may cause loosening or damage of the connection parts such as pipelines and flanges, thus triggering leakage accidents. If the leakage cannot be detected in time by the staff, certain losses will be caused. In addition, when the current injection pump is installed, installation holes need to be opened at the installation position. If the installation holes are drilled crooked, once the pump body is fixed, the pump body cannot be moved, and the situation where the water outlet of the pump body cannot be accurately docked with the pipeline may occur. Therefore, when installing the injection pump, the installation holes need to be repeatedly measured and compared, and the installation is not flexible and fast enough. Therefore, the utility model proposes an injection pump for oilfield water injection. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-3 shown, it relates to a water injection pump for oil fields, including an installation base plate 1. A T-shaped guide rail 2 is fixed on the upper surface of the installation base plate 1. Two sliding sleeves 3 are slidably connected to the surface of the guide rail 2. A top plate 4 is fixedly connected to the upper surfaces of the two sliding sleeves 3. A pump body 5 is fixedly connected to the upper surface of the top plate 4. A sound insulation cover 6 is fixed on the upper surface of the top plate 4 and outside the pump body 5. One side of the sound insulation cover 6 is an open design. A maintenance cover 8 is fixedly connected to the open side of the sound insulation cover 6. Sound insulation cotton 7 is fixedly connected to the inner walls of the maintenance cover 8 and the sound insulation cover 6. The water inlet and outlet of the pump body 5 are respectively connected with a water suction pipe 9 and a drain pipe 10. The water suction pipe 9 passes through the top wall of the sound insulation cover 6 and extends to the outside of the sound insulation cover 6. The drain pipe 10 passes through the side wall of the sound insulation cover 6 and extends to the outside of the sound insulation cover 6. A leak detection assembly is installed on the outer side wall of the sound insulation cover 6 and outside the drain pipe 10.

[0024] In this embodiment, both the water suction pipe 9 and the drain pipe 10 are connected to the water conveyance pipeline through flanges.

[0025] As Figure 1 shown, mounting holes are provided at the four corners of the installation base plate 1.

[0026] The installation base plate 1 can be fixed at the designated installation position of the water injection pump through the mounting holes.

[0027] As Figure 1 shown, a locking bolt 15 is penetrated and threadedly rotated through the top wall of the sliding sleeve 3.

[0028] The sliding sleeve 3 can move horizontally along the guide rail 2, so as to finely adjust the position of the pump body 5 on the surface of the top plate 4. After the adjustment is completed, the locking bolt 15 can be tightened to fix the sliding sleeve 3.

[0029] As Figure 2 and Figure 3 shown, a plurality of grooves 16 are formed in the inner top wall of the sliding sleeve 3, and a roller 17 is rotatably connected inside the groove 16. The bottom end of the roller 17 is attached to the upper surface of the guide rail 2.

[0030] When moving along the surface of the guide rail 2, the roller 17 can roll on the surface of the guide rail 2, thereby reducing the friction between the sliding sleeve 3 and the guide rail 2 and making the movement of the sliding sleeve 3 smoother.

[0031] As Figure 1 shown, the maintenance cover 8 is fixedly connected to the sound insulation cover 6 by bolts. Therefore, the maintenance cover 8 can be disassembled from the side of the sound insulation cover 6, which is convenient for maintaining or servicing the internal pump body 5.

[0032] As Figure 1 and Figure 2 shown, the leak detection assembly includes a side cover 11. A water leakage sensor 12 is fixed to the inner top wall of the side cover 11. A microcontroller 13 and an acoustic-optic alarm 14 are fixed to the upper surface of the side cover 11. The acoustic-optic alarm 14 and the water leakage sensor 12 are both electrically connected to the microcontroller 13. The side cover 11 is fixed to the outer side wall of the sound insulation cover 6 by bolts.

[0033] Therefore, the side cover 11 can be installed on the outer side wall of the sound insulation cover 6 after the drain pipe 10 is connected to the pipeline. After the installation is completed, if there is a leak at the flange where the drain pipe 10 is connected to the pipeline, the leaked water will splash onto the water leakage sensor 12. At this time, the microcontroller 13 will control the acoustic-optic alarm 14 to sound, so as to timely remind the staff to carry out maintenance.

[0034] Working principle: During installation, first drill holes at the specified positions, then install and fix the installation base plate 1 through the installation holes. Then move the sliding sleeve 3 to finely adjust the top plate 4 and the pump body 5 so that the drain pipe 10 can be aligned with the water delivery pipeline. After the adjustment is completed, tighten the locking bolt 15 to fix the sliding sleeve 3. Then install the side cover 11 on the surface of the sound insulation cover 6 by bolts. The noise generated when the pump body 5 works will be isolated by the sound insulation cotton 7 and the sound insulation cover 6, avoiding great influence on the staff in this environment. If there is a leak at the flange connection of the drain pipe 10 due to excessive pressure, the leaked water will splash onto the water leakage sensor 12. At this time, the microcontroller 13 will control the acoustic-optic alarm 14 to sound, timely reminding the staff to carry out maintenance.

[0035] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific embodiments. Obviously, many modifications and variations can be made according to the content of this specification. These embodiments are selected and specifically described in this specification in order to better explain the principle and practical application of the present utility model, so that those skilled in the relevant technical field can well understand and utilize the present utility model. The present utility model is only limited by the claims and their full scope and equivalents.
