Technical field
The utility model is the underground equipment of oil field pumping well, is to prevent the device of oil well rod tube corrosion and scaling, tool
Body is a kind of device of relay-type release medicament in pumpingh well.
Background technology
Oil field has been enter into development late stage, oil well casing, oil pipe, downhole tool corrosion and scaling at present by exploitation for many years
Problem is increasingly serious, especially high temperature and high salt oil deposit, such as Shengli Oil Field T128 fault blocks, the husky four 5-8 sand groups in main oil-bearing layer position, is
One is constructed-lithology glutenite bodies reservoir by lithologic character controlling, and Sand member permeability, which is mainly distributed, concentrates on 1-10 millidarcies
Between, reservoir temperature is 108 DEG C, between the mg/L of salinity 30,000-8 ten thousand, also different degrees of in associated gas to contain hydrogen sulfide and two
The corrosive gas such as carbonoxide, are the ligh-oil reservoir of high-temperature pressure, and such oil reservoir corrosion is more serious.Meanwhile, oil field was produced
Cheng Zhong, due to temperature, the change of pressure so that such reservoir formation, pit shaft, petroleum pipeline have different degrees of fouling.
During Oil/gas Well waterflooding extraction, loss is surprising caused by being influenceed by corrosion and scaling, and 10% metal loss is there are about every year
In corrosion, and adjacent to oil well area fouling, oil and gas flow passage can be blocked, declines Liquid output；Pit shaft fouling can bear oil well
Lotus increases, and reduces pump efficiency, or even can holddown, oil well stopping production.
In order to solve the problems, such as pumpingh well corrosion and scaling, oil field takes many measures, following anticorrosion sucker rod and oil pumping
Bar, but this material type anti-corrosion method somewhat expensive, anticorrosion, good antiscale property effect it is also undesirable, still an alternative is that
Anti-corrosion, antiscale medicament are squeezed into sleeve pipe, this method needs support to hold the dosing cycle, and management difficulty is larger, chemical feeding quantity is big to be needed
The equipment such as the vehicle of dosing, it is costly.
The content of the invention
The purpose of this utility model is the device of relay-type release medicament in a kind of pumpingh well of design, is solved above-mentioned
Problem, it is to avoid the tube rod of pumpingh well is corroded, prevents oil well pump and oil pipe fouling, it is ensured that oil well is normally produced for a long time, improves oil
The production cycle of well.
What the purpose of this utility model was realized in：Including tubing coupling, feed liquor screen casing, variable buckle box cupling, upper runner control
Throwing is stifled, upper medicament release, upper medicament memotron, middle part box cupling, lower flow channel control plug, lower medicament release, compound sun
