Abstract
A kind of vertical section thawing apparatus of well mouth of oil well; it is related with oil exploitation; it include: electric heater unit housing (1), electrically heated rod (2), cable (3), earth leakage protective device (4); it is characterized in that: the electric heater unit housing (1) is hollow tubular; its shape is in inverted "L" shape; its underpart is in pointed closed; the electrically heated rod (2) is placed in the bottom of the inside of electric heater unit housing (1); the electrically heated rod (2) is electrically connected by cable (3) with earth leakage protective device (4), and earth leakage protective device (4) is electrically connected with external power supply.The thawing apparatus solves the problems, such as well head frozen block in oil well winter production, instead of using special vehicle to sprain sweeping, saves special fare and uses, the oil well that frozen block can be made to stop production resumes production in time, improves crude output.
Description
Technical field
The utility model oil exploitation is related, and in particular to a kind of vertical section thawing apparatus of well mouth of oil well.
Background technique
Western oil field is located in high altitude localities, and temperature in winter is in 18 degrees below zero or so.Oil field is in later development, contains
Water is high, liquid measure is low, fuel-displaced interval, is easy to cause the vertical section pipeline frozen block of well mouth of oil well in winter, so that oil well be caused to stop production.For
Guarantee winter oil well normally produces, and solves the problems, such as that pipeline frozen block, traditional way are to sprain at the scene using special vehicle
Sweeping restores oil well production.And for aqueous higher oil well, pipeline is interior to freeze seriously, can not be sprained and be swept out at all with special vehicle, only
It can stop production or be resumed production using the interim electric lagging facility of pipeline installation is connected in winter, be removed when thawing to second year interim
Pipeline is changed into normal production flow line.Both take human and material resources in this way and is also consumed by certain electric energy.
Summary of the invention
The utility model the technical solution adopted is that: the vertical section thawing apparatus of a kind of well mouth of oil well, comprising: outside electric heater unit
Set, electrically heated rod, cable, earth leakage protective device, it is characterized in that: the electric heater unit housing is hollow tubular, shape is in
Inverted "L" shape, its underpart are in pointed closed, and the electrically heated rod is placed in the bottom of the inside of electric heater unit housing, institute
The electrically heated rod stated is electrically connected by cable with earth leakage protective device, and earth leakage protective device is electrically connected with external power supply.
The beneficial effect of the utility model is: solving the problems, such as well head frozen block in oil well winter production, replaces
It is sprained sweeping using special vehicle, saves special fare and use, the oil well that frozen block can be made to stop production resumes production in time, improves crude oil
Yield.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
In figure: 1, electric heater unit housing, 2, electrically heated rod, 3, cable, 4, earth leakage protective device.
Specific embodiment
In Fig. 1, a kind of vertical section thawing apparatus of well mouth of oil well, comprising: electric heater unit housing 1, electrically heated rod 2, cable
3, earth leakage protective device 4, it is characterized in that: the electric heater unit housing 1 is hollow tubular, shape is in inverted "L" shape, its underpart
In pointed closed, the electrically heated rod 2 is placed in the bottom of the inside of electric heater unit housing 1, the electrically heated rod 2
It is electrically connected by cable 3 with earth leakage protective device 4, earth leakage protective device 4 is electrically connected with external power supply.
The diameter of electric heater unit housing 1 is generally 19 mm, and length is generally 2m.The power of electrically heated rod is generally
1500w, diameter are generally 12mm, and length is generally 350mm.
When well head freezes, well head union and back-pressure gate are opened, which is inserted into the ice face of vertical section and is connected
Power supply is begun to warm up.The temperature of heater transmitting will soon melt the ice on top, this is that ice is heated simultaneously with water, heat after
Continuous transmitting downwards.When under heating device to below frozen soil layer, vertical section bottom will soon be reached, well head is completed and thaws.It takes out
Heating device, connection moving joint, oil well opening well and making production.
