Abstract
The utility model discloses a kind of forced action type paraffin remover injection device, it relates in a kind of oil extraction in oil field, for giving the device of paraffin removal from oil well, belongs to forced action type paraffin remover injection device.Overcome manually-operated drawback, provide a kind of and the diverse new device of prior art.This device is simple to operate, and removable many wells use, can in the high and low different aboveground application of pressure.In dosing process, automatically can control dosing method by micro computer, sealing operation is free from environmental pollution, to constructor without harm.Serve the effect of paraffin remover liquid of mechanically annotating.When oil well pressure is flowed out by liquid blending tank (2) lower than paraffin remover liquid during atmospheric pressure, one way valve (9) is arrived by gravity flow valve (13), then flow in well by snap joint (11), when borehole pressure is higher than liquid height pressure difference in liquid blending tank (2), start electric gear wheel pump, at this moment liquid forces liquid to be pressed onto in well from the pressure valve (6) in left side through electric gear wheel pump (7) pressurization, finally completes the injection work of paraffin remover liquid.
Description
Technical field
The utility model relates in a kind of oil extraction in oil field, for giving the device of paraffin removal from oil well, belongs to forced action type paraffin remover injection device.
Background technology
Have several for the method for paraffin removal from oil well in oil extraction in oil field at present, have hot water well-flushing method, add paraffin remover method.And in the method adding paraffin remover, what generally adopt is all manual method, so not only labour intensity is large, also can bring harm to the health of people.When the pressure of oil well is too large, manual method is inoperable.Therefore, a kind of method that can replace manually adding paraffin remover is badly in need of.
Summary of the invention
The purpose of this utility model is the weak point avoiding existing in above-mentioned current technology, and provides a kind of and the diverse new device of prior art.This device is simple to operate, and removable many wells use, can in the high and low different aboveground application of pressure.In dosing process, automatically can control dosing method by micro computer, sealing operation is free from environmental pollution, to constructor without harm.
The utility model can reach by the following technical programs: this forced action type paraffin remover injection device comprises liquid blending tank, dosing tank, car body is equipped with liquid blending tank, whole tank body have employed stainless steel, at the rear lower portion leftward position boring also welded steel pipe joint of liquid mixing tank body, coupling is connected with pressure valve, the exit of valve is forced to be connected with electric gear pump inlet by steel pipe pipe nipple, electric gear pump discharge rectilinear direction is connected with snap joint by steel pipe pipe nipple, preservative treatment has been done in electric gear wheel pump inside, electric gear pump discharge steel pipe pipe nipple outer wall is equipped with pressure meter respectively, pressure sensor, relief valve, at the rear lower portion right positions boring also welded steel pipe joint of liquid mixing tank body, coupling is connected with gravity flow valve, the exit of gravity flow valve is connected with one way valve by steel pipe pipe nipple, on gravity flow valve export steel pipe pipe nipple outer wall, discharging valve is equipped with in bypass, and gravity flow valve export steel pipe pipe nipple outer wall is equipped with flow transmitter.The outlet of one way valve is communicated with electric gear pump discharge steel pipe pipe nipple by steel pipe pipe nipple; At the leftward position boring of the middle part below also welded steel pipe joint of liquid mixing tank body, coupling is connected with dosing valve, and the exit of dosing valve is connected with dosing tank by steel pipe pipe nipple; Portable switchbox can be connected with 220 of a scene volt power supply when operation, electromagnetic starter, CPU is provided with in portable switchbox inside, the output of electromagnetic starter is connected on the motor of electric gear wheel pump by two wires, the controlled end of electromagnetic starter is connected with the control end of CPU, and the signals collecting end of CPU is connected with pressure sensor, flow transmitter respectively.
The utility model can also reach by the following technical programs: when oil well pressure is flowed out by liquid blending tank 2 by atmospheric pressure lower than paraffin remover liquid during atmospheric pressure, one way valve 9 is arrived by gravity flow valve 13, liquid in liquid blending tank 2 by height pressure difference, one way valve 9 is opened, liquid by after one way valve 9 and electric gear wheel pump 7 outlet line converge, then flowed in well by snap joint 11.When borehole pressure is higher than liquid height pressure difference in liquid blending tank 2, one way valve 9 is closed, liquid flow in pipeline stops, at this moment flow transmitter 15 can't detect liquid flowing state, and send the signal of telecommunication to CPU17, after CPU17 receives signal, signal is amplified and controls electromagnetic starter 12, start electric gear wheel pump, at this moment liquid forces liquid to be pressed onto in well from the pressure valve 6 in left side through electric gear wheel pump 7 pressurization, when the pressure in well is reduced to lower than atmospheric pressure, pressure sensor 16 will send the signal of telecommunication to CPU17, after CPU17 receives signal, signal is amplified and controls electromagnetic starter 12, close electric gear wheel pump 7, at this moment one way valve 9 is opened again, be switched to again from stream mode.Finally complete the injection work of paraffin remover liquid.The effect of discharging valve 14 is when entering winter, after having noted liquid, discharging valve 14 is opened, has all released, the liquid in tank with anti-freeze.The effect of relief valve 10 is after operation completes, and opens relief valve 10 and eliminates pressure between snap joint and shaft collar.
The present invention has the following advantages than above-mentioned prior art: this device is simple to operate, and removable many wells use, can in the high and low different aboveground application of pressure.In dosing process, automatically can control dosing method by micro computer, sealing operation is free from environmental pollution, to constructor without harm.Revolutionize traditional artificial adding method thereof.
