Abstract
The utility model relates to a heat-conductive continuous oil sucking rod which comprises a continuous hollow oil sucking rod, wherein sealing plugs are arranged on both ends of the continuous hollow oil sucking rod; a liquid phase change heat-conductive working medium is arranged in a hollow cavity of the continuous hollow oil sucking rod. The utility model has the technical scheme that a film-plating layer is arranged on the inner wall of the hollow cavity of the continuous hollow oil sucking rod; reinforcing clogging plates are arranged at the outsides of the sealing plugs on both ends of the continuous hollow oil sucking rod. The utility model completes the conduction of oil well bottom terrestrial heat to the upper part of an oil well by the phase change of the liquid heat-conductive working medium below the continuous hollow oil sucking rod because of terrestrial heat, realizes the viscosity reduction of crude oil in the process that the crude oil is lifted to the ground from a well bottom and raises the oil production efficiency of an oil pumping machine. The utility model has the characteristics of simple structure, convenient assembly and disassembly, high work reliability and low operating cost.
Description
Technical field
The utility model relates to deep-well oil exploitation sucker rod, is a kind of heat conduction coiled rod specifically.
Background technology
Crude oil is promoted on ground in the dark oil well of last km, and one of the reaction force that the oil pumper work done is produced is a gravity, and one is the frictional resistance of the borehole wall.The viscosity temperature of crude oil is very responsive, in the process that crude oil is raised, reduction along with formation temperature, viscosity is increasing, the frictional resistance that produces is also increasing, the oil recovery efficiency of oil pumper is reduced, can stop up pit shaft when the crude oil wax phenomenon of Chu Xianing is serious simultaneously, influence normally carrying out of oil producing operation.Traditional viscosity reducing technology has chemical viscosity reduction, hot fluid circulation heating viscosity reduction and electrical heating viscosity reduction, and chemical viscosity reduction easily influences former oil quality, and hot fluid circulation heating viscosity reduction need use equipment and fuel, and the electrical heating viscosity reduction need expend a large amount of electric energy.The recent discloseder method and apparatus that utilizes underground heat to carry out viscosity reduction, though solved the problem that chemical viscosity reduction, hot fluid circulation heating viscosity reduction and electrical heating viscosity reduction exist, but still exist the composition complex structure in actual applications, installation difficulty is big and dependability is low and raw material expend the high problem of cost.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of underground heat that can effectively utilize is provided, and simple in structure, and loading, unloading are convenient, functional reliability height, the heat conduction coiled rod that use cost is low.
The technical scheme that realizes above-mentioned purpose is: a kind of heat conduction coiled rod, it comprises a continuous hollow sucker rod, is provided with the shutoff plug at the two ends of this sucker rod, adds the liquid phase-change heat-conducting work medium in the hollow cavity of sucker rod.
The technical solution of the utility model also comprises: the hollow lumen wall of sucker rod is provided with the plated film layer; There is the shutoff of reinforcement plate at two ends at sucker rod in the arranged outside of shutoff plug.
This heat conduction coiled rod utilizes underground heat to realize the reducing crude oil viscosity of oil recovery process, compare with the electrical heating viscosity reduction with chemical viscosity reduction, hot fluid circulation heating viscosity reduction, has the advantage that does not influence former oil quality and do not have energy consumption, and compare with similar underground heat viscosity reduction, because integral body is a coiled rod, not only make the job stability height of product, processing and easy for installation, and reel easy to use furls sucker rod when playing well, it is simple in structure to have composition, easy to use, reliable operation, the characteristics that running cost is low.
Description of drawings
Accompanying drawing is this heat conduction coiled rod structural representation.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
Provide as accompanying drawing, the utlity model has one whole continuous hollow sucker rod 1, be provided with shutoff plug 2 at the two ends of sucker rod 1, its shutoff plug can adopt thread fiting mode and sucker rod to assemble.Add liquid phase-change heat-conducting work medium 3 in the hollow cavity of sucker rod, its liquid phase-change working medium can be used alcohols, water, hydro carbons of different boiling and composition thereof, compound, and installing volume additional is 5% to 35% of inner chamber total measurement (volume).
As accompanying drawing embodiment, the utility model can be provided with plated film layer 4 on the hollow lumen wall of sucker rod 1, to improve the Corrosion Protection and the surface flatness of sucker rod internal chamber wall.
When the utility model is specifically implemented, set up reinforcement shutoff plate 5 in the outside of shutoff plug 2 through welding at the two ends of sucker rod 1, to improve the sealing of the sucker rod chambers of the heart.
The chambers of the heart vacuumized processing after the filling of this sucker rod heat-conducting work medium was finished.
The last well of this heat conduction coiled rod is installed and is undertaken by common coiled rod mounting method.
