Description
Technical field
This utility model relates to underground mining field, is specially a kind of coal bed gas well dosing with pressure watering device.
Background technology
In recent years, China is increasingly faster to the development rate of coal bed gas well, middle petrochemical industry in Shanxi, Shaanxi, expensive
The ground such as state, Anhui carries out exploration and development in succession, along with exploration and development gradually deeply, find part well by
In high salinity, faintly acid, cause the problem that tube rod corrodes containing antibacterial etc., and day by day serious, well workover
Labor intensive financial resources.Being studied by corrosion-resistanting test, the employing cycle adds corrosion inhibiter to sleeve pipe and can effectively subtract
Slow tubing and casing etching problem.
Coal bed gas well is owing to using oil pipe to produce water mining blood pressure lowering, and the mode of sleeve pipe aerogenesis produces.Therefore,
After coal bed gas well continuous gas generation, the interpolation of corrosion inhibitor to be carried out is the most difficult, uses plunger displacement pump to add
The mode of medicine wastes time and energy, and is limited requirement by personnel, is more unfavorable for patrol dosing.Therefore, Shanxi
East China, Xiangning County unconventional headquarter of oil gas field make dosing watering device with pressure by oneself, make coal bed gas well dosing realize
Quick dosing with pressure, saves the plenty of time.
Middle petrochemical industry East China branch company coal bed gas well exploration and development progress is increasingly faster, and block scale is more and more deeper
Greatly, the etching problem that the cbm development stage occurs is badly in need of solving.Coal bed gas anticorrosion is different from conventional gas and oil
Well anticorrosion, coal bed gas rely primarily on oil pipe produce water, sleeve pipe aerogenesis, therefore, from the beginning of coal bed gas aerogenesis,
Sleeve tube pressure anticorrosion dosing is particularly important.But, in terms of the state of the art, have after sleeve pipe aerogenesis
Having certain casing pressure, dosing must use plunger displacement pump to carry out dosing, and plunger displacement pump dosing speed is slow, time-consumingly consumes
Power, this technology contributes to sleeve tube pressure dosing, can carry out water mixing in coal bed gas well aerogenesis any stage
And medicament adds, have broad application prospects.
This utility model is the deficiency of dosing with pressure after aiming to overcome that sleeve pipe aerogenesis, and As-Is is coal seam
There is serious etching problem in producing in gas, serious hindrance coal bed gas well " continuously, slowly, stable,
Eight word mining policies for a long time ", have impact on being excused from a college course the phase of coal bed gas individual well, and the novel advantage of utilitarian design exists
It is difficult to dosing, when casing pressure to be overcome after sleeve pipe aerogenesis carries out water mixing and adds after sleeve pipe aerogenesis
Medicine difficulty is the biggest.Coal bed gas well adds heavy corrosion owing to there is bacterial corrosion and CO2 dividing potential drop, it is necessary to add
Anti-corrosion agent carries out dosing.But from the point of view of current Technology, also do not carry out for sleeve pipe gas-producing well
The reliability method of dosing and mode.Normal dosing after applying this device to ensure that coal bed gas well aerogenesis
And water mixing, low liquid measure gas-producing well use water mixing with pressure guarantee fast jig frequency take out of in well coal dust and
Residue, down-hole waterflooding also can control producing fluid level fall.Simultaneously apply this device can at gas-producing well
Ensure effective dosing, prevent coal bed gas well because corrosion causes the generation of well workover situation.
Utility model content
The purpose of this utility model is to provide a kind of coal bed gas well dosing with pressure watering device, and it can be effective
Solution background technology present in problem.
For achieving the above object, this utility model provides following technical scheme: a kind of coal bed gas well is with pressure adds
