Description
Technical field
This utility model relates to technical field of petroleum extraction, is specifically related to oil field back washing device.
Background technology
Oil effect oil in national economy is important energy source, with coal facies ratio, have that energy density big (the oil combustion ratio of specific heat standard coal waiting weight is high by 50%), shipping storage be convenient, after burning to advantages such as the pollution level of air are less.The fuel oil refined from oil is the main fuel of the various kiln of means of transport, station boiler, metallurgical industry and building material industry.With oil be raw material liquefied gas and piped gas be life of urban resident application high-grade fuel.Aircraft, tank, naval vessels, rocket and other spacecrafts, also consume bulk petroleum fuel.Therefore, many countries are all classified as oil as strategic materials.The feature of oil exploitation is compared with general solid mineral reserve, there are three distinguishing features: the object 1. exploited constantly flows in the process of whole exploitation, oil reservoir situation constantly changes, all measures must carry out for this situation, therefore, the whole process of exploitation of oil-gas field be a continuous understanding, the process updated；2. exploitation person does not directly contact with ore body in the ordinary course of things.The exploitation of oil gas, to the understanding of situation in oil-gas reservoir and oil-gas reservoir is exerted one's influence carry out various measure, will be undertaken by special well logging；3. some feature of oil-gas reservoir must in process of production, even just must will appreciate that after well number is more, therefore, and exploration and mining phase usually mutual weave within a period of time
Oil exploitation process is launched mainly through the mode excavating oil field, water filling is one of important measures of oil field high yield, stable yields, offshore oilfield sand control completion water injection string does not possess well-flushing function, water injection well long-term injecting water has dirt, precipitation, corrosive deposit etc. and injects stratum, water-injection efficiency is made to reduce, tubing string lifts up difficulty, increases the difficulty of water injection work, it would be highly desirable to improve.
Utility model content
The purpose of this utility model is in that the defect for prior art and deficiency, a kind of simple in construction, oil field back washing device reasonable in design, easy to use are provided, have water injection pipe backwashing function, effectively remove dirt, impurity and erosion in water injection pipe, extending the service life of water injection pipe, practicality is higher.
For achieving the above object, the technical solution adopted in the utility model is: it comprises water injection pipe, outer tube, backwash water pipe, backwash fountain head, water tank, backwash high pressure water valve, backwash water valve, through hole；Water injection pipe be provided externally with outer tube；It is provided with backwash water pipe between described outer tube and water injection pipe, backwash water pipe is connected to several backwash fountain heads；Described backwash fountain head is arranged in the through hole on water injection pipe tube wall；Described water tank is arranged on the top of water injection pipe, and water pipe is provided with backwash high pressure water valve and backwash water valve；Described backwash high pressure water valve and backwash water valve are disposed in parallel on backwash water pipe.
It is provided with sealing ring between described through hole and backwash fountain head, for improving the sealing between through hole and backwash fountain head, improves the sealing of water injection pipe.
Operation principle of the present utility model: when water injection pipe inwall is carried out backwash by needs, can first open backwash high pressure water valve, water in water tank sprays water under high pressure from backwash fountain head, incrustation scale or impurity that backwash fountain head surface can be gathered by the water under high pressure of ejection spray, then turn off backwash high pressure water valve, open backwash water valve, water injection pipe inwall is carried out backwash, after backwash terminates, close backwash water valve.
After adopting said structure, this utility model has the beneficial effect that oil field described in the utility model back washing device, have water injection pipe backwashing function, effectively remove dirt, impurity and erosion in water injection pipe, extend the service life of water injection pipe, practicality is higher, and has simple in construction, arranges the advantages such as reasonable, cost of manufacture is low.
