Abstract

The utility model relates to a normal pressure oil well hot washing paraffin removal replacement device in oil field. The utility model adopts the technical scheme that the device mainly comprises a combustor, a sleeve, a firebox, a fluid inlet pipe, superconducting fluid storage tanks, a fluid outlet pipe, partition boards and a furnace body, wherein, the inner chamber of the furnace body is divided by two partition boards into two superconducting fluid storage tanks and a firebox in between, the superconducting fluid storage tanks contain superconducting fluids, the sleeve which is communicated at a time is arranged in the firebox, an oil pipe is arranged in the sleeve to be communicated with the fluid inlet pipe and the fluid outlet pipe respectively, the two superconducting fluid storage tanks are communicated with the sleeve, and the firebox, when heated by the combustor, can heat the oil pipe through the superconducting fluids, to increase fluid temperature in the oil pipe. With the benefits of rapid temperature increase, high heating efficiency and speedy paraffin removal, the utility model not only can remove paraffin and scale, but also can remove soluble organic blocking substances such as paraffin, asphalt, mechanical impurities and the like present in a sieve tube and a spray aperture section, thereby ensuring stratum oil flows ceaselessly into a well bottom through an unblocked oil circuit, with greatly increased well fluid productivity.

Description

Normal pressure hot cleanout and paraffin removal of oil well displacement apparatus

One, technical field:

The utility model relates to a kind of oil field heating furnace, particularly a kind of normal pressure hot cleanout and paraffin removal of oil well displacement apparatus.

Two, background technology:

The wax removal of oil well and wax control are important measures that guarantee the oil well ordinary production, usually adopt two kinds of method control wax deposition now, the one, wax control, employing chemical paraffin inhibitor or physics method are avoided separating out of wax and are adhered to, and the 2nd, wax removal, according to actual conditions cycle wax removal dirt, the method of wax removal is a lot, mechanical paraffin cutting, paraffin removing with chemical method or inject oil well with hot water and steam wax is melted, developed the ultrasonic wave wax removal in the recent period again, as bacterial paraffin removal.First three kind is the main at present method of using in the said method, wherein hot-washing wax remover such as paraffin control with inhibitor are ripe relatively, but also there are a lot of deficiencies in these wax removal techniques: the one, and chemistry needs regularly to add medicament, wax removal cost height in oil well, contaminated environment not only, and its wax removal is thorough inadequately; The 2nd, the cost height of hot water and steam wax removal, expense is big, complex procedures, main hot water, the steam heat wax high honour of relying on, in order to guarantee the wax removal effect, require big discharge capacity, a large amount of injection pit shaft hot water (generally being to inject 40 cubes-60 cubes) also needs to efflux for a long time, all need 5-8 days time to discharge, influence output.Part oil well energy is lower, and hot washing lotion is poured in down a chimney bottom easily and caused formation contaminant, and output is difficult to return to normal level behind the well-flushing, and severe patient makes oil well not fuel-displaced.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of normal pressure hot cleanout and paraffin removal of oil well displacement apparatus is provided, and reduces cost, and reduces oil layer pollution, and environment pollution is increased economic efficiency.

Its technical scheme is: mainly be made up of burner, sleeve pipe, burner hearth, feed tube, superconducting fluid storage tank, drain pipe, dividing plate and body of heater, the inner chamber of described body of heater isolates two superconducting fluid storage tanks and middle burner hearth respectively by two dividing plates, in the superconducting fluid storage tank superconducting fluid is housed, be provided with the sleeve pipe that once is communicated with in the burner hearth, oil pipe is housed in the sleeve pipe, be communicated with feed tube and drain pipe respectively, described two superconducting fluid storage tanks are communicated with sleeve pipe, burner heats burner hearth, by superconducting fluid oil pipe is heated, improve the fluid temperature in the oil pipe.

Be provided with bleed off pipe in the above-mentioned body of heater, outlet is installed in the body of heater top.

The bottom of above-mentioned body of heater is provided with support.

The beneficial effects of the utility model are: quick heating, thermal efficiency height, wax removal are quick, not only wax removal is washed dirt, and can also dispose in the screen casing and the organic obstruction material of solubility of perforation footpath section, as wax, pitch, mechanical admixture etc., the mediation oil circuit is that stratum fluid flows into the shaft bottom continuously, increases substantially the well output of fluid.

Four, description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Among the last figure: burner (1), sleeve pipe (2), burner hearth (3), support (4), feed tube (5), superconducting fluid storage tank (6), drain pipe (7), bleed off pipe (8), dividing plate (9) and body of heater (10).

Five, the specific embodiment:

In conjunction with the accompanying drawings 1, the utility model will be further described:

Mainly by burner 1, sleeve pipe 2, burner hearth 3, support 4, feed tube 5, superconducting fluid storage tank 6, drain pipe 7, bleed off pipe 8, dividing plate 9 and body of heater 10 are formed, the inner chamber of described body of heater 10 isolates two superconducting fluid storage tanks 6 and middle burner hearth 3 respectively by two dividing plates 9, in the superconducting fluid storage tank 6 superconducting fluid is housed, be provided with the sleeve pipe 2 that once is communicated with in the burner hearth 3, oil pipe is housed in the sleeve pipe, be communicated with feed tube 5 and drain pipe 7 respectively, described two superconducting fluid storage tanks 6 are communicated with

sleeve pipe

2,3 heating of 1 pair of burner hearth of burner, by superconducting fluid oil pipe is heated, improve the fluid temperature in the oil pipe, be provided with bleed off pipe 8 in the body of heater 10, outlet is installed in the body of heater top, and the bottom of body of heater 10 is provided with support 4.

This device utilizes oil pumper as power, after the speed intensification with several times in this device of liquid process of extracting out, be recycled into oil pipe and sleeve pipe annular body, and descend along pipe with the speed of per second number meter, flow into the shaft bottom fast, force oil pipe and well liquid temp to raise, the oil-pipe external wall temperature is raise, because reciprocal circulation, temperature constantly improves, oil pumper is constantly worked, liquid measure improves constantly, the circulation with the displacement, the time and constantly heat, form a vertical displacement system, thereby realized the purpose of hot-washing wax remover volume increase.

This device is quick heating under the effect of displacement heat transfer agent, thermal efficiency height, wax removal are quick, not only wax removal is washed dirt, and can also dispose in the screen casing and the organic obstruction material of solubility of perforation footpath section, as wax, pitch, mechanical admixture etc., the mediation oil circuit is that stratum fluid flows into the shaft bottom continuously, increases substantially the well output of fluid.

The oil well fluid of this device is that medium and stratum compatibility are not well destroyed the stratum, and the polluted reservoir face of land does not need to efflux raising output.
