Description

Technical Field

[0001] The utility model relates to the technical field of fracturing equipment, and particularly relates to a fracturing unit for oilfield exploitation. Background Technique

[0002] The so-called fracturing refers to a method of forming fractures in oil and gas reservoirs by using hydraulic action during oil or gas production. Artificially creating fractures in the formation can improve the underground flow environment of oil, increase the oil well production, and play an important role in improving the bottom-hole flow conditions of oil wells, reducing interlayer interference, and improving the utilization status of oil layers. During the fracturing process, a fracturing unit is required. During the use of a fracturing truck, after the drain pipe is used to inject fracturing fluid, a large amount of oil remains on the surface of the drain pipe. If it is not cleaned in time, the oil will cause certain corrosion to the drain pipe. For example, the patent publication number CN202022804353.0 discloses a fracturing unit for oilfield exploitation. This solution realizes the cleaning of the fracturing pump oil pipe through a nozzle, but this cleaning method is relatively simple. On the one hand, it cannot reciprocally spray and clean the oil pipe. Secondly, this solution only cleans the oil pipe by spraying, and cannot brush it with a brush, and there are defects in inconvenient disassembly and assembly. Therefore, improvements are needed.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment

[0023] As Figure 1 and Figure 2 shown, a fracturing unit for oilfield exploitation proposed in an embodiment of the present invention includes a bottom plate 1. A mounting frame 3 is arranged on a support base 2 on the upper surface of the bottom plate 1. A fracturing pump 4 is installed on one side of the mounting frame 3, and an oil pipe 6 is communicated with one side of the fracturing pump 4. A bracket 7 is fixedly connected to the bottom plate 1, and a cleaning module 5 for cleaning the oil pipe 6 is installed on the bracket 7. The cleaning module 5 includes a vertical plate 501 fixedly connected to the bracket 7 and a support plate 502 fixedly connected to one side of the vertical plate 501. A guide rod 503 is arranged between two corresponding support plates 502 up and down, and a lifting plate 504 is sleeved on the guide rod 503. A detachable support board 505 is arranged on one side of the lifting plate 504, and a lifting cleaning component 506 for reciprocally cleaning the oil pipe 6 is arranged at the end of the support board 505.

[0024] It should be noted that the bottom plate 1 is fixed to the vehicle body. The mounting bracket 3 is used for mounting components such as the fracturing pump 4. A tubing 6 is arranged on one side of the fracturing pump 4. The fracturing fluid is input into the oilfield through the tubing 6 for oilfield exploitation. By arranging a bracket 7 on the bottom plate 1 for mounting the cleaning module 5, the cleaning module 5 can be used to achieve the spray cleaning of the tubing 6, avoiding the tubing 6 being contaminated with oil, which may affect the storage of the tubing 6. The main part of the cleaning module 5 is a vertical plate 501. By arranging a guide rod 503 on the support plate 502, the guide rod 503 realizes the lifting and guiding function of the lifting plate 504. When the lifting plate 504 moves up and down, it can drive the lifting cleaning component 506 to move, and then the tubing 6 is reciprocally sprayed and brushed by the lifting cleaning component 506.

[0025] As Figure 2 and Figure 3 shown, in some embodiments, the lifting cleaning component 506 includes a first protective block 5061 and a second protective block 5063. Among them, the first protective block 5061 is fixedly connected to the support plate 505. Both the first protective block 5061 and the second protective block 5063 are provided with convex edges 5062, and the convex edges 5062 are fixed with bolts.

[0026] It should be noted that the lifting cleaning component 506 is of a split design and is composed of the first protective block 5061 and the second protective block 5063, which facilitates the insertion of the tubing 6 on the lifting cleaning component 506, and then facilitates the cleaning and maintenance of the tubing 6. The convex edges 5062 are fixed with bolts to realize the fixation between the first protective block 5061 and the second protective block 5063.

[0027] As Figure 3 shown, in some embodiments, circular grooves are provided at the centers of the first protective block 5061 and the second protective block 5063, and a brush 5066 is fixedly connected to the circular grooves of the first protective block 5061 and the second protective block 5063.

[0028] It should be noted that by fixedly connecting the brush 5066 to the circular grooves of the first protective block 5061 and the second protective block 5063, the brush 5066 contacts the outer wall of the tubing 6 to realize the effective cleaning of the tubing 6.

[0029] As Figure 3 shown, in some embodiments, spray racks 5064 are fixedly connected to one side of the first protective block 5061 and the second protective block 5063, and spray nozzles 5065 are installed on the spray racks 5064.

[0030] It should be noted that a water pump can be installed on the bottom plate 1, and the water pump is communicated with the spray nozzles 5065, and then the reciprocating spray cleaning of the tubing 6 is realized.

[0031] As Figure 2As shown, in some embodiments, the support plate 505 is inserted into the cavity of the lifting plate 504, and the support plate 505 is fixed to the lifting plate 504 by screws.

[0032] It should be noted that after the support plate 505 is inserted into the lifting plate 504, it is fixed by screws to realize the assembly of the support plate 505. It can be removed when not in use, which is very convenient.

[0033] As Figure 2 and Figure 3 shown, in some embodiments, a servo motor 5010 is installed on the motor base 5011 fixed by the bracket 7, and a connecting rod 509 is fixedly connected to one side of the servo motor 5010. The end of the connecting rod 509 is rotatably connected to a rotating arm 508, and the end of the rotating arm 508 away from the connecting rod 509 is rotatably connected to a rotating seat 507 provided on the upper surface of the lifting plate 504.

[0034] It should be noted that when it is necessary to control the reciprocating movement of the lifting plate 504 and the lifting cleaning component 506, the servo motor 5010 is driven to work. The servo motor 5010 drives the connecting rod 509 to rotate, and then drives the rotating arm 508 to swing. By means of the rotating arm 508, the lifting plate 504 is cyclically pulled and pushed, so that the lifting plate 504 moves cyclically on the guide rod 503, realizing the lifting drive of the lifting cleaning component 506, and then realizing the reciprocating spraying and brushing of the oil pipe 6.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention 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 perform equivalent replacements on some of the technical features.
