Abstract

A high-efficiency superconductive oil well heater is an oil-field pipeline heating conveyer, and resolves the defects of the other technologies. The heater consists of a case, a buffer tank, an internal liner, an external liner, an outlet, a heating element, heat-conducting oil, an inlet, heating medium, a lifting ring and a distributor box; wherein, the buffer tank is connected with the internal liner through a conduit; the upper side of the external liner is provided with the outlet; the lower side of the external liner is provided with the inlet; the external liner is connected with the internal liner through flanges; the heating element is positioned in the internal liner, and is welded on the flanges of the external liner and the internal liner; the heat-conducting oil is loaded in the internal liner; the heating medium is filled between the external liner and the internal liner; the distributor box is mounted on the case; and the lifting ring is fixed on the top of the case. During the operation, the heating element heats the oil-conducting oil, the internal liner conducts heat to the heating medium, thus realizing the heat exchange. The heater has the advantages of no dry burning, explosion prevention, long service life, low reparation cost and high working efficiency.

Description

The high-efficiency superconducting Oil well heater

One, technical field:

The utility model relates to oil field pipe and adds heat transfer apparatus, especially the high-efficiency superconducting Oil well heater.

Two, background technology:

The oil field in process of production because oil contains wax, the time grow, these waxes will block up oil pipe, present dewaxing method is to heat with electrothermal tube to dredge, electrothermal tube burns out easily; Perishable, the life-span is short.

Three, summary of the invention:

The purpose of this utility model provides a kind of high-efficiency superconducting Oil well heater of long service life, it has solved the shortcoming of other technology, the purpose of this utility model is to realize like this, it is to be formed by connecting by casing, surge tank, inner bag, outer courage, outlet, heating element, conduction oil, import, heat medium, suspension ring and switchbox, and surge tank is connected by pipeline with inner bag; There is outlet the courage upper end outside, and import is arranged at the bottom of outer courage; Outer courage is connected by flange with inner bag, and heating element is positioned at inner bag, and is welded on the flange of outer courage and inner bag; Conduction oil is arranged in the inner bag; Heat medium in the middle of outer courage and the inner bag; Switchbox is installed on the casing, is fixing suspension ring on the top of casing.

During work, with heat-conducting oil heating, inner bag is passed to heat medium with heat again by heating element, and carries out interchange of heat.

This installs not dry combustion method, can be explosion-proof, and long service life, maintenance cost is few, high efficiency.

Four, description of drawings:

Fig. 1 is the structural representation of high-efficiency superconducting Oil well heater, among the figure 1, casing 2, surge tank 3, inner bag 4, outer courage 5, outlet 6, heating element 7, conduction oil 8, import 9, heat medium 10, suspension ring 11, switchbox

Five, the specific embodiment:

In Fig. 1, surge tank 2 and inner bag 3 are connected by pipeline; There is outlet 5 courage 4 upper ends outside, and import 8 is arranged at the bottom of outer courage 4; Outer courage 4 and inner bag 3 are connected by flange; Heating element 6 is positioned at inner bag 3, and is welded on the flange of outer courage 4 and inner bag 3; Conduction oil 7 is arranged in the inner bag 3; In the middle of outer courage 4 and the inner bag 3 is heat medium 9; Switchbox 11 is installed on the casing 1, is fixing suspension ring 10 on the top of casing 1.
