Description

Technical Field

[0001] The invention relates to the technical field of oil fields, in particular to an adjustable foundation filling and compacting device for oil fields. Background Art

[0002] After the oil production operation is completed at an oil site, corresponding oil well facilities will be left behind. If the site has good wind energy resource conditions and geographical advantages, in order to fully activate idle land resources and realize the green transformation of the energy industry, the abandoned oil wells will be professionally and permanently sealed in strict accordance with environmental protection standards to completely eliminate the risk of underground oil and gas leakage, so as to facilitate the subsequent installation of wind power equipment foundations. Therefore, in order to ensure that the oil site can well fix the wind power equipment for construction, the oil site will be filled and compacted. This not only effectively eliminates the hidden dangers of stratum subsidence and forms a uniform and stable foundation bearing capacity, but also provides reliable support for the subsequent foundation construction of large-power wind turbines, avoiding waste of land resources and reducing the land acquisition cost of wind power projects.

[0003] In order to ensure the subsequent installation of wind power generation, the filling sand and gravel are usually pressed down. Some special operations will adopt deeper foundation compaction operations, so the filling compaction device needs to be inserted deep underground to complete the compaction operation. However, the commonly used filling devices usually do not have a good adjustment mechanism to compact the filling sand and gravel. The adjustment mechanism is difficult to bear the high downward pressure, causing the adjustment mechanism to deform, thereby reducing the compaction quality of the filling compaction device and affecting the subsequent construction. Summary of the Invention

[0004] The present invention application discloses an adjustable foundation filling and compacting device for oil fields, which solves the problem proposed in the above background technology that the commonly used filling devices usually do not have a good adjustment mechanism to compact the filled sand and gravel, and the adjustment mechanism is difficult to bear the high downward pressure, thereby resulting in a decrease in the compaction quality of the filling and compacting device, affecting the later construction.

[0005] The present invention provides an adjustable foundation filling and compacting device for oil fields, which specifically includes: an inner casing, an outer casing fixedly sleeved on the outside of the inner casing; a screen pipe fixedly sleeved on the inside of the inner casing; a pipe plug fixedly installed on the bottom of the screen pipe; six groups of adjustment support frames fixedly installed in a circular array inside the pipe plug; an adjustment seat rotatably provided on the bottom of the adjustment support frame.

[0006] As a further solution of the present invention, the screen pipe further comprises: a sealing joint fixedly installed on the top of the screen pipe; and a centralizer fixedly installed on the outside below the screen pipe.

[0007] As a further solution of the present invention, the screen pipe also includes: a connecting bracket, which is shaped like a circular frame structure and rotates in the middle of the bottom of the pipe plug; and an adjusting cylinder, which rotates at the bottom of the connecting bracket.

[0008] As a further solution of the present invention, the shape of the adjustable support frame is an L-shaped structure; the adjustable support frame also includes: a mounting joint, the number of the mounting joints is set to two, and the mounting joints are symmetrically fixedly installed at one end of the top of the adjustable support frame; a limit cylinder, the limit cylinder is fixedly installed inside the mounting joint; a limit side block, the shape of the limit side block is a rectangular block structure, and the number of the limit side blocks is set to two, and the limit side blocks are symmetrically and integrally arranged at one end of the mounting joint; As a further solution of the present invention, the adjustment support frame also includes: a limit slider, the limit slider is shaped like an L-shaped block structure, and the bottom of one side of the limit slider is an arc-shaped structure, and the limit slider slides on the bottom of the adjustment support frame; a transmission joint, the transmission joint is shaped like an arc-shaped structure, and the transmission joint is integrally arranged on the top of the limit slider; the transmission joint is fixedly connected to one end of the piston rod of the limit cylinder; a matching block, the matching block is shaped like a rectangular block structure, and one side of the matching block is designed with an arc-shaped structure, and the matching block is fixed to one end of the bottom of the adjustment support frame.

[0009] As a further solution of the present invention, the adjustment seat also includes: a cooperating bracket, which rotates in the middle of the top of the adjustment seat; a rotational connection between the cooperating bracket and the piston rod of the adjustment cylinder; a mounting seat, which has a circular seat structure, and the number of mounting seats is set to four, and the mounting seat is fixedly installed in the middle of the adjustment seat in a cross shape; a downward pressure cylinder, which is fixedly installed inside the mounting seat.

[0010] As a further solution of the present invention, the adjustment seat also includes: an integrated bracket, the number of the integrated brackets is set to six groups, and the integrated brackets are arranged in a circular array on the outside of the adjustment seat; an adjustment pillar, the shape of the adjustment pillar is a circular column structure, and the adjustment pillar is integrally arranged at one end of the integrated bracket; the adjustment pillar is rotatably connected to the limit slider and the mating block.

[0011] As a further solution of the present invention, the adjustment seat also includes: a lower pressure plate, which is shaped like a circular plate structure and is fixedly installed at the bottom of the piston rod of the adjustment cylinder; a buffer plate, which is shaped like a circular plate structure and is fixedly installed at the bottom of the lower pressure plate.

[0012] The adjustable foundation filling and compacting device for oil fields provided by the present invention has the following beneficial effects: Through the setting of the adjustment seat, when the compaction angle of the lower pressure plate needs to be adjusted according to the actual filling requirements, the operator first needs to start five groups of limit cylinders. The piston rod of each limit cylinder will extend and retract according to the predetermined stroke, and transmit the power to the limit slider through the transmission joint connected to it. Driven by the transmission joint, the limit slider begins to move along the predetermined track. The limit slider that was originally tightly fitted on the top of the matching block gradually breaks away from the contact with the matching block. At this time, the adjustment pillar restricted by the five groups of limit sliders is freed from the original restricted state. While these five groups of limit sliders are freed from the restriction, there is still a group of limit sliders that maintains the restrictive effect on the adjustment pillar, ensuring that the adjustment pillar can still maintain a certain stability after being freed from some restrictions, providing reliable support for subsequent angle adjustments.

[0013] When the adjustment support is in this partially restricted state, the adjustment cylinder starts to work, and the piston rod of the adjustment cylinder drives the adjustment seat to move under the action of air pressure. During the movement, the adjustment seat is restricted by the set of limit sliders and will tilt toward the side of the adjustment support corresponding to the limit slider. As the adjustment seat tilts, the compaction angle of the lower pressure plate installed on it also changes accordingly. This angle change is precisely controllable. The operator can accurately adjust the compaction angle of the lower pressure plate by precisely controlling the working status of the limit cylinder and the adjustment cylinder according to actual production needs. Through this adjustment method, the dead angle in the compaction process can be effectively reduced, and the material can be subjected to more uniform pressure during the compaction process, thereby improving the compaction quality of the oil filling site, effectively eliminating the hidden dangers of stratum subsidence, forming a uniform and stable foundation bearing capacity, and ensuring the stability and consistency of the installation of wind power equipment.

[0014] In addition, the system adopts a design in which a limit slider, a matching block and an adjustment pillar cooperate with each other and cooperate with an adjustment cylinder for transmission, which has many significant advantages. When the downward pressure cylinder performs a downward pressure operation, this matching method can effectively increase the compressive strength after adjustment. The close cooperation between the limit slider and the matching block, as well as the stable support of the adjustment pillar, enable the entire adjustment system to maintain structural stability and rigidity when subjected to downward pressure. The precise transmission of the adjustment cylinder ensures uniform and stable power transmission during the downward pressure process, thereby further improving the stability of the compaction operation after the compaction angle is adjusted. This improvement in stability can not only ensure the compaction quality of the product, but also extend the service life of the equipment, reduce the maintenance cost of the equipment, and bring higher economic benefits to the enterprise.
