Description
Affiliated technical field
The utility model relates to a kind of soup and doses device, especially a kind of oil well automatic medicine adding apparatus that is used for the well mouth of oil well dosing.
Background technology
Because the oil well in the oil field in use easily causes the corrosion and the fouling of down-hole string and gathering line because of height is moisture,, wax deposition thick because of oil easily causes problems such as the undesired and wellhead back pressure height of oil well production, need in system, to add various chemical agents, to realize tasks such as inhibition, wax control, viscosity reduction.For addressing this problem, what people mostly taked at present is the slug formula adding method thereof that adds every day or several days once, though this method can realize the task of dosing to a certain extent, have can not be in time evenly dosing and its labour intensity is big, dosing complex procedures, the relatively poor defective of effect.
Summary of the invention
Task of the present utility model be to provide a kind of can be automatically, in time, uniformly to the oil well automatic medicine adding apparatus of oil well dosing.
For realizing above-mentioned task, the technical scheme that the utility model is taked comprises that chemicals dosing plant and automatic controller two parts form, it is characterized in that: described chemicals dosing plant is to be provided with explosive box in housing, upside at explosive box is provided with the drawer type medicine-chest lid that explosive box can be locked in the housing, in explosive box, be provided with electrothermal tube by automatic controller control, the control valve that is arranged in the housing and is connected in series successively by pipeline, dosing pump, outlet valve, ball-and-seat, control valve and explosive box intracavity inter-connection, the output of this serial connection pipeline sleeve gate by being arranged on the oil well end is connected with sleeve pipe on the oil well.Described automatic controller is made up of digital display time relay and temperature controller and is positioned in the housing.The power input of digital display time relay is connected with the 220V AC power, the ac power input end of digital display time relay i.e. " live wire end " is connected with the timing closing end, another timing closing end is connected with the power end of dosing pump, and another power end of dosing pump is that " 0 " line end is connected with ac power input end; The power input of temperature controller is connected with the 220V AC power, the ac power input end of temperature controller i.e. " live wire end " is connected with the control signal output of temperature controller, behind the coil of another control signal output serial connection A.C. contactor of temperature controller with the input of AC power promptly " 0 " line end be connected, two ends of electrothermal tube are connected with AC power with two groups of constant open contact serial connection backs of A.C. contactor respectively, and the sampled signal input of temperature controller is connected with thermocouple.
Owing to adopted technique scheme, during the utility model work, earlier the drawer type explosive box is opened, add predetermined soup, as thinner, anticorrosive, detergent etc., locking explosive box after soup is filled it up with, to realize open-air antitheft task, open control valve, the power switch of closed digital display time relay, under the control of digital display time relay, the work of dosing pump time opening, in the effect of dosing pump, the soup in the explosive box is through valve, thereby ball-and-seat and sleeve gate enter interior realizing the oil well Automatic Dosing of the task of sleeve pipe in the oil well.The purpose that adds outlet valve in system is for the gas in the discharge system, simultaneously in order to prevent that the oil in the oil well from flowing backwards, and adds ball-and-seat in system.When using the utility model, when ambient temperature is low, but the power switch of closed temperature controller, this moment, thermocouple was sent into the temperature sampling in the temperature controller, make temperature controller work, A.C. contactor gets electric work, two constant open contact closures get electrothermal tube and electric soup in the explosive box are heated, when soup is heated to predetermined temperature, temperature controller quits work automatically, so comes and goes circulation, makes soup remain good degree of adhesion, be beneficial to the smooth filling of soup and give full play to its drug effect, thus the task that realization is heated automatically.
The beneficial effects of the utility model: the one owing to adopted the technical scheme of Automatic Dosing, thus have easy to use, labour intensity is little, dosing characteristics promptly and accurately; The 2nd owing to adopted to the automatic heating technology scheme of soup, so have compliance strong, can adapt to the characteristics of under the condition of different temperatures, working; The 3rd, because whole device has been taked the technical scheme of locking, so have antitheft technical characterstic; The 4th, because the utility model overall structure is simple, so have low cost of manufacture, be suitable for the characteristics that popularize.
