Abstract
The utility model relates to a heating device for oil wells, being mainly used for increasing the yield of thick oil wells and high-wax oil wells. The utility model comprises an oil delivery pipe, and has the essential structure that a guard pipe is arranged outside the oil delivery pipe, heat transfer oil is filled in a seal cavity which is arranged between the guard pipe and the oil delivery pipe, and a conducting winding outside the oil delivery pipe is connected with a temperature control electric device through an electric cable. The utility model has the advantage of simple structure, and can increase the yield.
Description
The utility model relates to the heater of oil well, is mainly used in the device that improves heavy oil wells, high wax oil well production.
Main path for heavy oil wells, high wax oil well raising oil recovery amount is to inject vapours or oil in oil reservoir at present, but effect is all undesirable, and the complex structure of its equipment, huge.
The purpose of this utility model is exactly at the problems referred to above, provides a kind of simple in structure, improves the Oil well heater of produce oil better effects if.
The purpose of this utility model is achieved in that the utility model comprises petroleum pipeline, its structural feature is that petroleum pipeline is outside equipped with pillar, be filled with conduction oil in the annular seal space between pillar and the petroleum pipeline, the outer conduction coiling of petroleum pipeline links to each other with the temperature control electric installation by cable.
Major advantage of the present utility model:
1. simple in structure:
The utility model mainly is made up of petroleum pipeline, pillar, conduction coiling, temperature control electric installation, and its assembly is few, and body is simple, is easy to make, promote;
2. can improve oil production:
When the utility model device is switched on, outer wall at this device has been subjected to heating, make outer wall thinning the releasing of oil on every side, oil after the dilution enters in the petroleum pipeline of the present utility model again and heats once more, oil is pumped smoothly is drawn onto on the ground, can make the existing output of PR improve 1-2 doubly.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an electrical block diagram of the present utility model;
Fig. 3 is an installation site of the present utility model schematic diagram.
Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:
The utility model comprises petroleum pipeline 7, and petroleum pipeline 7 is outside equipped with pillar 4, is filled with conduction oil in the annular seal space 2 between pillar 4 and the petroleum pipeline 7, and petroleum pipeline 7 outer conduction coilings 5 link to each other with the temperature control electric installation by cable 8.
The two ends of pillar 4 are respectively arranged with flange 1, flange 9; Be provided with three magnetic guiding loops 3 in the annular seal space 2, (magnetic guiding loop 3 makes and produces stronger magnetic loop in the annular seal space 2, increases eddy-current loss, produces more heat.) conduction coiling 5 is divided into three groups, and be dihedral 11 and connect; Conduction coiling 5 is connected with cable 8 by copper screw bolt 6.
The temperature control electric installation is the current techique that those of ordinary skill is easily implemented.
Temperature control electric installation of the present utility model comprises rectification circuit, filter circuit, inverter circuit.Rectification circuit comprises trigger, bridge rectifier, and trigger is by triggering integrated package N
