Background technology
At present, the domestic equipment that under the airtight situation of high-pressure oil-gas well, adds chemical agent that does not still have maturation.Though airtight dosing wraps in and has realized the dosing of oil well band pressure on the principle, but at the scene in the application process, long-pending less (8L) contained in dosing, can't satisfy the demand (40～60L/ time) that the scene adds dose, and medicament flow velocity degree is slow, administration timing of drug is longer, every mouthful of well administration timing of drug needed more than 40 minutes, inefficiency, and the field control difficulty is big, to the oil well dosing of oil jacket annular pressure greater than 2.0MPa, medicament flow velocity degree is more slow especially.
The utility model content
The purpose of this utility model is: provide a kind of skid-mounted airtight chemicals dosing plant, realize medicine under the oil well band pressure condition, and can add fast, automatic gauge, reduce the on-the-spot dosing labour intensity of employee, to disperse dosing method to change into concentrated dosing simultaneously, and further improve the oil well band and press the dosing operating efficiency.It is long-pending less to overcome existing dosing containing, and the dosing flow velocity is slow, and administration timing of drug is long, ineffective deficiency.
The technical solution adopted in the utility model is: the airtight chemicals dosing plant of skid-mounted, mainly form by ball-and-seat, dosing pump, flow meter, medicine storing pot, electromagnetic valve, booster pump and suction pump, medicine storing pot 6 is the horizontal cylindrical tanks that adopt stainless steel materials weldering system, on the medicine storing pot outer wall content gauge is arranged, be convenient to observe dose in the medicine storing pot, steam vent is arranged at the medicine storing pot top, and blowoff valve is arranged at the bottom of the medicine storing pot.It is characterized in that: inlet is arranged at the top at medicine storing pot, and inlet has pipeline to connect suction pump.Suction pump can pump into medicament in the medicine storing pot in chemical tank.Have liquid outlet, medicine storing pot 6 liquid outlets to have pipeline to connect booster pump in the medicine storing pot bottom, the booster pump outlet connects electromagnetic valve, and the electromagnetic valve other end has pipeline connection traffic meter, and the outlet of flow meter is connected with dosing pump; Be connected with ball-and-seat at the dosing delivery side of pump.Ball-and-seat can be connected with the well-head valve of production tree by pipeline.
In order to hold different types of chemical agent, described medicine storing pot has two.
In order independently to finish dosing work, medicine storing pot is fixed on the sledge seat, is fixed with diesel-driven generator on the sledge seat, and diesel-driven generator provides electric power for dosing pump, flow meter, electromagnetic valve and suction pump.
In order to make the dosing accurate measurement, dosing pump, flow meter, electromagnetic valve and booster pump have lead to be connected automatic control system.
The course of work of the airtight chemicals dosing plant of skid-mounted: consult Fig. 1.At first, open diesel-driven generator, for medicine system provides power.By suction pump 10 two medicine storing pots 6 are filled it up with medicament; Then, on the digital display screen of control system, preset the dose that adds of dosing oil well, press releasing the button on the switch board; Start booster pump 9 and plunger dosing pump 4 medicament in the medicine storing pot 6 is injected the well-head valve 2 of production tree 1, implement the dosing of oil well annular space by well-head valve 2.In the dosing process, flow meter 5 automatic gauges add dose, and convert digital data transmission to control system, control system is compared according to the dose of gathering that adds that adds the dose signal and preset, when adding dose reach default when adding dose, automatic control system is sent the termination of pumping instruction, and booster pump 9 and plunger dosing pump 4 stop, and finish whole dosing process.
The beneficial effects of the utility model: the airtight chemicals dosing plant of the utility model skid-mounted, realize medicine under the oil well band pressure condition, can add fast, each administration timing of drug only is 3～5 minutes.The dosing automatic gauge reduces the on-the-spot dosing labour intensity of employee, will disperse dosing method to change into concentrated dosing simultaneously, further improves the oil well band and presses the dosing operating efficiency.It is big to take dose, and it is accurate to add dose.
