Description
Technical field
The utility model belongs to from well producing oil, gas, water, the method for solubility or solubilized material or slurry of mineral or equipment technical field, is specifically related to the equipment injecting wax removing agent in oil pipe.
Background technology
Because oil well is produced in (oil recovery) process normal, tubing wall can accumulate the wax of constantly separating out from crude oil gradually, due to the adhewsive action of wax, oil pipe caliber can be made to be tapered, area of passage reduces, thus oil well output is constantly declined, and this is a process that cannot change.The common technology that current oil well solves wax deposition problem has two kinds: one to be by heating means, wax deposition is melted, and solves oil well paraffinication.Two is adopt chemical method to solve oil well paraffinication, adds the liquid paraffin remover based on benzene, and adding paraffin remover is one of most effective measures of preventing producing well wax deposition at present.Current filling please cured agent method be artificial filling, the paraffin remover of 200 liters of drum packagings is dispensed in different containers according to actual needs and delivers to each well again, during filling, first by the emptying valve open of wellhead casing pipe, residual air in emptying sleeve pipe and oil pipe space, residual air discharges this valve of rear closedown, again by valve closing outside grug feeding jar, appropriate paraffin remover is poured into from grug feeding jar import, after paraffin remover liquid level stabilizing, again by emptying valve open, now paraffin remover will flow under the influence of gravity in the annular space of sleeve pipe and oil pipe.And the defect that this method exists has the following aspects:
(1), in the transfer process from drum to different vessels, there will be waste and loss; (2) benzene is toxic liquid, in transfer process, produces unavoidably pollute and adverse effect human and environment; (3) manually annotate, will inevitably by the impact of people inaccuracy; (4) affect the fine-grained management of producing well.
In technical field of petroleum extraction, the technical problem that current need urgently solve asks cured dose for well servicing to provide a kind of equipment.
Summary of the invention
The shortcomings such as technical problem to be solved in the utility model is to overcome paraffin remover waste existing for prior art, environment pollution, adding amount inaccuracy, management do not become more meticulous, provide the paraffin remover filling apparatus that a kind of structure is simple, paraffin remover filling is effective, simple to operate, easy to maintenance.
Solving the problems of the technologies described above adopted technical scheme is: base upper left side is provided with dosing pump, right side is provided with liquid feeding gun carriage, the inlet of dosing pump is connected by suction hose and suction pipe joint, suction pipe joint is provided with feed tube, the liquid outlet of dosing pump is provided with the pressure switch that wire is connected with dosing pump, one outlet conduit of pressure switch is provided with pressure meter, another outlet conduit is provided with fluid flexible pipe, liquid feeding gun carriage is provided with infusion tube reel and liquid feeding rifle, infusion tube reel is provided with infusion tube, entrance is provided with and fluid flexible pipe is connected on the right side of infusion tube reel, the swivel joint that outlet and infusion tube are connected, entrance and the infusion tube of liquid feeding rifle are connected, outlet and gauge table are connected, gauge table is connected by discharging tube and well head connector assembly.
Suction hose of the present utility model, fluid flexible pipe, infusion tube, discharging tube are polyfluortetraethylene pipe.
Well head connector assembly of the present utility model is: the right-hand member of joint body is provided with union, is provided with 2 sealing mats between pipe socket end and joint body, is provided with O RunddichtringO between 2 sealing mats.
Sealing mat of the present utility model is polytetrafluoroethylene sealing gasket, and O RunddichtringO is viton seal ring or silicone rubber O-ring.
Because the utility model have employed dosing pump, liquid feeding rifle and gauge table, gauge table accurately can control the adding amount of paraffin remover, avoid waste, owing to being filling with pressure, need not residual air in emptying oil well, accelerate filling speed, avoid and discharge residual air to the pollution of air and the generation causing deflagration accident having, the pipeline adopted is polyfluortetraethylene pipe, effectively can prevent the attachment of corrosion and wax.The utility model has the advantages such as reasonable in design, structure is simple, paraffin remover filling speed is fast, accurate-metering, non-environmental-pollution, simple to operate, easy to maintenance, result of use is good, can be widely used in oil well.
