Abstract
A wellhead heating pipe. The main problem of solving current well head heating device heating efficiency low, the operation is complicated. The method is characterized in that: the heating device is characterized in that the safety valve (3) is connected to the side wall of the upper portion of the heating outer sleeve (6), the spherical sealing rubber sleeve (4) is sleeved outside the heating outer sleeve (6) at the lower portion of the safety valve (3), the electric heating pipe (5) is arranged inside the heating outer sleeve (6), heat conduction oil (7) is filled around the electric heating pipe (5), the electric heating pipe (5) is fixed to the connecting sleeve (2), and the top of the connecting sleeve (2) is connected with the hanging ring (1). The wellhead heating pipe is high in heating efficiency, convenient to install, safe and reliable, and reduces oil extraction cost.
Description
Technical Field
The utility model relates to an oil field, a well head heating pipe that is used for oil-water well head to unfreeze specifically says so.
Background
In cold northern areas, liquid in the wellhead device of the oil-water well is always at a lower temperature, has high viscosity, is easy to freeze, has reduced liquidity, and is easy to cause wellhead blockage, thereby influencing bailing oil production operation. At present, boiler steam is adopted for melting, so that the heating efficiency is low and the operation is complex.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough of current well head heating device heating efficiency low, the operation is complicated, the utility model provides a well head heating pipe, this well head heating pipe heating efficiency is high, simple to operate, and safe and reliable reduces the oil recovery cost.
The technical scheme of the utility model is that: the utility model provides a well head heating pipe, includes the heating outer tube, heating outer tube top links to each other with the adapter sleeve, be connected with the relief valve on the lateral wall on heating outer tube upper portion, the outside cover of heating outer tube of relief valve lower part has spherical sealing rubber cover, and heating outer tube inside is equipped with electric heating pipe, and the peripheral packing of electric heating pipe has the conduction oil, electric heating pipe fixes on the adapter sleeve, and the adapter sleeve top is connected with rings.
The top of the electric heating pipe is connected with a power socket, and a temperature control switch is arranged on the power socket.
The utility model discloses following beneficial effect has: by adopting the scheme, the wellhead heating pipe is seated on the wellhead, so that the wellhead heating pipe does not need to be disassembled and assembled, and is convenient to install; when heating, only a power supply is connected through a power socket, so that the operation is convenient, and the heating efficiency is high; the safety valve can release pressure, and is safe and environment-friendly.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of a power socket.
In the figure, 1-a hanging ring, 2-a connecting sleeve, 3-a safety valve, 4-a sealing rubber sleeve, 5-an electric heating pipe, 6-a heating outer sleeve, 7-heat conducting oil, 8-a sealing clapboard, 9-a power socket and 10-a temperature control switch.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1-2, a wellhead heating pipe comprises a heating outer sleeve 6, the top of the heating outer sleeve 6 is connected with a connecting sleeve 2, the heating outer sleeve 6 is connected with a bailing counterweight pipe, a safety valve 3 is connected on the side wall of the upper part of the heating outer sleeve 6, a spherical sealing rubber sleeve 4 is sleeved on the heating outer sleeve 6 at the lower part of the safety valve 3, and two ends of the sealing rubber sleeve 4 are abutted against steps on the outer wall of the heating outer sleeve 6, so that the function of the sealing sleeve can be achieved. The inside heat-conducting oil 7 that has filled of heating outer tube 6, heating outer tube 6 is inside to be equipped with electric heating pipe 5, and electric heating pipe 5 fixes on adapter sleeve 2, 2 tops of adapter sleeve are connected with rings 1, and rings 1 encapsulates electric heating pipe 5 inside. When the electric heating tube works, the hanging ring 1 is taken down, the top of the electric heating tube 5 is connected with a power socket 9, and a temperature control switch 10 is arranged on the power socket 9. The bottom of the heating outer sleeve 6 is connected with a sealing clapboard 8, and the heat conducting oil 7 and the electric heating tube 5 are sealed inside the heating outer sleeve 6.
This well head heating pipe with drag for counter weight union coupling back, sits on the well head, need not the dismouting, unloads rings 1 before the use, connects supply socket 9 on electric heating pipe 5, connects external power supply through supply socket 9, can unfreeze the well head about 15 minutes, the degree of depth of unfreezing is 1.5 meters. After thawing, the heating pipe is arranged back to the hanging ring 1 for fishing, and the heating pipe can work in a reciprocating way along with the fishing pipe column. After the heat conducting oil 7 is heated, the internal pressure of the heating outer sleeve 6 is increased, and the pressure can be automatically released through the safety valve 3, so that the heating process is safer.
Claims (2)
1. The utility model provides a well head heating pipe, includes heating outer tube (6), and heating outer tube (6) top links to each other its characterized in that with adapter sleeve (2): the heating device is characterized in that the safety valve (3) is connected to the side wall of the upper portion of the heating outer sleeve (6), the spherical sealing rubber sleeve (4) is sleeved outside the heating outer sleeve (6) at the lower portion of the safety valve (3), the electric heating pipe (5) is arranged inside the heating outer sleeve (6), heat conduction oil (7) is filled around the electric heating pipe (5), the electric heating pipe (5) is fixed to the connecting sleeve (2), and the top of the connecting sleeve (2) is connected with the hanging ring (1).
2. The wellhead heating pipe according to claim 1, wherein: the top of the electric heating pipe (5) is connected with a power socket (9), and a temperature control switch (10) is arranged on the power socket (9).
