The apparatus in the utility model is advantaged by clean flow channel provided by a self-excited oscillation cavitation nozzle, simple technology, low cost, concentrated energy, great depth of treatment, clear water as working medium, no pollution, easy combination with other technologies, many functions, capability of selecting jet pressure, rotating speed, and treatment layer according to blocking type and seriousness degree, and wide application to petroleum exploitation blocking removing, yield increasing and injection increasing technologies.
Description
One, technical field
The utility model relates to oil exploitation plugging removal and stimulation facility, particularly a kind of high-pressure water jet rotary plug-removing increasing yield and injection device.
Two, background technology
The oil field of waterflooding extraction, present characteristics such as moisture rising, oil production are successively decreased, oil recovery factor is low gradually, some producing wells are owing to liquid contamination and mechanical admixture precipitation in drilling well, completion, underground work and long-term oil recovery, the water filling manufacturing process, cause the near wellbore zone to stop up, cause oil production and water injection rate to descend even stopping production.At present the processing method of using generally have chemistry, physics etc., physical methods such as wherein hydraulic vibration method, supercritical ultrasonics technology, electric liquid impulse method, gas fracturing method, artificial earthquake method, The field has obtained effect in various degree, but also have following shortcoming or deficiency: 1. construction is complicated, the cost height; 2. act on singlely, limited by conditions down-hole, the finite energy of generation; 3. it is not really desirable to handle the degree of depth and effect.
Three, summary of the invention
The purpose of this utility model provides a kind of high-pressure water jet rotary plug-removing increasing yield and injection device, adopt strainer, one way valve, Rotation Controllers and self-resonating cavitating jet nozzle combining structure, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
High-pressure water jet rotary plug-removing increasing yield and injection device described in the utility model, comprise top connection, strainer, backwash valve, centralizer, damper and shower nozzle, it is characterized in that described backwash valve upper end is connected with top connection with strainer in turn, the lower end is connected with strainer, connector, centralizer, damper and shower nozzle in turn.
Wherein, described strainer comprises outer tube and its interior sand screen is installed.Described backwash valve comprises housing and interior valve seat and the valve ball of installing in turn thereof, and sand screen is connected with valve seat.Described housing is provided with the backwash passage.Described damper comprises the rotating shaft and the bearing of shell and interior installation thereof.Between described shell and the rotating shaft seal is installed.On the described shower nozzle nozzle is installed.Be distributed with 2-8 nozzle on the periphery of described shower nozzle.
The utility model has following advantage compared with prior art:
1, is provided with the self-oscillation cavitation nozzle, removes oil-water well near wellbore zone contamination and plugging, the flow channel of a cleaning is provided for gas stream or water filling.
2, technology is simple, cost is low;
