Description

Pressurized timing and quantitative chemical adding device for oil pumping well

Technical Field

The utility model relates to a clear, wax control device of mechanical development oil specifically is a timing, ration charge device are pressed in rod-pumped well area.

Background

In the mechanical production oil well in oil exploitation, the oil pumping unit changes the rotation motion of a motor into the up-and-down reciprocating motion of the oil pumping unit through a four-bar mechanism, so that the oil pumping unit is driven to exploit oil to the ground. The wax is continuously separated out in the process that the petroleum rises in the oil and rod annular space, and part of the wax flows out of a wellhead along with the petroleum; the other part of wax is condensed on the wall of the oil pipe, the surface of the sleeve pipe and the surface of the sucker rod, the thickness of the pipe and the rod is increased, the gap between the pipe and the rod is gradually reduced, the production of the oil well is influenced, and the wax in the oil well is blocked in severe cases. To address this phenomenon, the conventional solution at present is to add a chemical paraffin cleaner from the casing, and the paraffin cleaner enters from the suction port of the pump and mixes with the petroleum to dissolve the wax. At present, the wax remover is extruded into a sleeve by a pump during dosing, the extrusion amount is large each time, a part of the wax remover cannot play a role and is pumped out, the chemical agent has large harm to human bodies, and the oil extraction operation cost is high.

Disclosure of Invention

The utility model discloses a technical problem who solves is: in the traditional technology, the wax removing agent has larger extrusion amount each time, part of the wax removing agent is sucked out, the wax removing effect cannot be achieved, and the operation cost is higher.

The technical proposal of the utility model for solving the technical problem is that:

the utility model provides a pressure is pressed, timing, quantitative charge device, oval liquid storage pot upper portion sealing connection paraffin removal agent funnel valve, paraffin removal agent funnel, lower part sealing connection solenoid valve, lower control valve, eccentric reducing nipple joint, liquid storage pot side upper portion sealing connection control valve, the left end of going up the control valve passes through the air balance valve and is connected with eccentric reducing nipple joint upper portion sealing, the left end of eccentric reducing nipple joint and sheathed tube sleeve valve sealing connection, the sleeve valve and sleeve pipe sealing connection, paraffin removal agent gets into the sleeve pipe at the time sequence under the control of solenoid valve.

The utility model has the advantages that:

under the action of gas balance and gravity, the paraffin remover is controlled by the electromagnetic valve in a timing and quantitative time sequence, and is added into the sleeve pipe as required without being extruded into the paraffin remover by a pump, so that the consumption of the paraffin remover is reduced, the operating cost is reduced, and the harm of the paraffin remover to operators is effectively reduced.

The using method comprises the following steps: when the paraffin removing agent is added, the air balance valve and the lower control valve are closed, the blow-down valve is opened to release pressure, the paraffin removing agent funnel valve is opened after the pressure is released, the paraffin removing agent is added into the liquid storage tank from the paraffin removing agent funnel, then the paraffin removing agent funnel valve and the blow-down valve are closed, the air balance valve and the lower control valve are opened, the paraffin removing agent enters the sleeve through the eccentric reducing nipple and the sleeve valve to realize automatic timing and quantitative addition of the paraffin removing agent under the action of air balance and gravity through the time sequence control of the electromagnetic valve, so that the paraffin removing purpose is realized.
