Abstract
A hot water mixed thickened oil exploiting paraffin removal device applied on an oil pumping machine well is composed of a control device on the ground and an under-well water mixing device. A control cabinet is installed on a hot water accompanied conveying pipeline, a three-way connector is arranged on the upper portion of a hollow oil pumping rod, and a valve is arranged on the lower portion of the three-way connector. A check valve is arranged on the lower portion of the hollow oil pumping rod. During working, hot water passes through a high-pressure flexible rubber tube and the three-way connector, enters into the hollow oil pumping tube and finally enters into an oil tube through the check valve. Sticky oil mixed in the oil tube forms oil-in-water emulsion and is lifted to an above-ground pipeline by means of the oil pump, thereby reducing thickness and resistance of the oil pump and improving crude oil production. The hot water mixed thickened oil exploiting paraffin removal device is simple in structure, low in investment compared with an existing electric heating mode, good in effect and convenient to maintain, and solves the problems of energy waste and high production cost caused by the electric heating device.
Description
Skill is asked the field
The utility model is announced is that a kind of hot water that is used on the rod-pumped well is mixed and adopted thick oil paraffin removal device.
Background technology
Hide more and more at oil field development viscous crude, high waxy oil at present.Adopting when taking out operation, because oily thick wax content is high, causing the epicuticular wax dirt to be bonded on tube inner wall and the sucker rod top layer, the oil pumper resistance is increased, lifting force inadequately and can't ordinary production.Address this problem, just must be the sticking oily wax desaturation in the oil pipe.What now sticking oily wax desaturation was adopted all is electric calorifie installation, with electric heating the crude oil in the oil pipe is heated.Make the crude oil dissolving desaturation in the oil pipe, so just can under the effect of oil pump, be given rise to ground smoothly.But the power consumption of this electric calorifie installation is bigger, disposable having high input, and maintenance cost is high, has strengthened cost of production.
Summary of the invention
To above-mentioned situation, the purpose of the utility model just provides a kind of hot water and mixes and adopt thick oil paraffin removal device, with solve viscous crude, high content of wax block well is adopted the difficult problem of taking out, and also solves existing electric heater unit and wastes energy, equipment investment is big, problems such as cost of production height.
The technical scheme that the utility model is taked for solution existing apparatus problem is: be made up of ground control device and down-hole water mixing device.On the defeated pipeline of hot water companion, a switch board is housed, between hollow rod and switch board, has the high pressure flexible rubber hose.On the top of hollow rod one threeway is arranged, one valve is arranged in the bottom of threeway.Bottom at hollow rod has ball-and-seat.Have oil well pump in the ball-and-seat bottom, the bottom of oil pipe has screen casing.There is oil pipe the outside of hollow rod, and there is sleeve pipe the outside of oil pipe.Oil-out is arranged at the top at oil pipe.Connect oil pipeline on the ground on the oil-out.The use of the utility model is that switch board is installed near the oil well, accompanies hot oil transportation hot water to insert the Ground Control cabinet on ground, and the high pressure flexible rubber hose is connected in the threeway.Switch board is accomplished pressure, heats the control of flow.Hot water is through the high pressure flexible rubber hose during work, and threeway gets into hollow rod, gets into oil pipe through ball-and-seat again.Be blended in the sticking oil in the oil pipe and form oil-in-water emulsion, under the effect of oil well pump, give rise in the abovegrade piping.Thereby reach viscosity reduction and take out thick purpose.Reduced the resistance of oil pumper, made oil well pump realize taking out normally act.Improved crude output.The utility model is simple in structure, and it is little that contrast conventional electric heating mode has investment, effective and the characteristics of being convenient to keep in repair.Solved wasting energy and the high problem of cost of production that electric heater unit brings.
