Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oilfield water injection development devices, in particular to a deep penetration cleaning and slow acidification device. Background Art
[0002] A water injection well is a well used to inject water into an oil reservoir. During the development of an oilfield, water is injected into the oil reservoir through a dedicated water injection well to maintain or restore the reservoir pressure, so that the oil reservoir has a strong driving force to improve the production rate and recovery rate of the oil reservoir. The exploitation period of an oilfield is usually long. As time goes by, the water injection capacity of the water injection well will gradually decrease. There are many reasons for the decrease in the water injection capacity of the water injection well, including sediment blockage, accumulation of sediment, sand and impurities in or around the well, resulting in the blockage of the water flow channel, and water source depletion, decline of the groundwater level or exhaustion of the water source, resulting in insufficient water volume, as well as reasons such as the swelling of clay attached to the pore wall and particle migration.
[0003] In the prior art, when acidizing and unblocking a water injection well, acid liquid is usually directly discharged into the well to react with the blockage, so as to acidify and corrode the blockage. Generally, a nozzle is directly used for liquid discharge, but the discharge range of the nozzle is limited, and it can only wait for the acid liquid to diffuse slowly, resulting in a long reaction time and affecting the subsequent use of the water injection well. At the same time, the nozzle is directly in contact with soil and gravel, which is easy to block and affects the discharge of acid liquid. Content of the Utility Model
[0004] The utility model aims at the deficiencies of the prior art and provides the following technical solutions:
[0005] A deep penetration cleaning and slow acidification device includes a tank body. A top cover is arranged at the top of the tank body. A plurality of hose holes are opened at the top of the top cover. A motor is fixedly connected to the inner bottom of the tank body. The output end of the motor is fixedly connected to a connection disk. A toothed ring is fixedly connected to the top of the connection disk. The toothed ring is rotatably connected to the inner side of an outer ring. The outer ring is fixedly connected to the inner wall of the tank body. An inner ring is arranged inside the outer ring. A plurality of sliding grooves are opened in both the inner ring and the outer ring.
[0006] As an improvement of the above technical solution, a rack is slidably connected in the sliding groove. A limiting member is fixedly connected to one side of the rack. An infusion mechanism is arranged at the top of the rack.
[0007] As an improvement of the above technical solution, the infusion mechanism includes a sliding member fixedly connected to the top of the rack. A plurality of clamping rings are symmetrically arranged inside the sliding member. A hose is arranged inside the clamping ring. One end of the hose is provided with a second quick connector. A one-way valve is arranged at one end inside the sliding member. A first quick connector adapted to the second quick connector is arranged on one side of the one-way valve.
[0008] As an improvement to the above technical solution, a drain pipe is provided at one end of the sliding member, a spray head is provided inside the drain pipe, a check valve is fixedly connected to one end of the spray head, and a plurality of drain holes are symmetrically formed on the outer side of the drain pipe.
[0009] As an improvement to the above technical solution, a first filter screen is provided at the top end of the drain hole, and a second filter screen is provided at the bottom end of the drain hole.
[0010] As an improvement to the above technical solution, a connecting ring is fixedly connected to the center of the top of the top cover, a plurality of fixing members are evenly and rotatably connected to the outer side of the top end of the tank body, and a plurality of notches adapted to the sliding member are formed on the outer side of the tank body.
[0011] As an improvement to the above technical solution, a gear is provided between the inner ring and the outer ring, and the gear is respectively meshed with a rack and a toothed ring.
[0012] Advantages of the present utility model:
[0013] 1. The motor drives the connecting disk to rotate to drive the toothed ring inside the outer ring to rotate together. When the toothed ring rotates, the gear is driven to rotate by means of meshing connection. When the gear rotates, the rack will also be driven to move. The movement direction of the rack is restricted by the limiting member and the sliding groove. The infusion mechanism on the top of the rack is driven to move by moving the rack, which can not only prevent external impurities from directly contacting the spray head, but also expand the acidification range, increase the contact surface with impurities, and improve the acidification effect.
[0014] 2. The hose is clamped by the clamping ring to strengthen the fixing effect. A check valve is installed at the spray head to prevent external liquid from flowing back. The hose and the spray head are quickly installed by using the first quick connector and the second quick connector, which is convenient and time-saving. Two layers of filter screens are installed at the drain holes on the outer side of the drain pipe. The first filter screen and the second filter screen can filter impurities of larger and smaller sizes. At the same time, the drain pipe is pointed, which can be inserted into the soil more easily.
