Embodiment 1

[0042] First aspect, such as Figure 1-7As shown, the present invention improves a gas-electric dual-purpose heat pipe heater for oil field wellhead heating, including a heater body 1, a burner 2, a heating cylinder 3, a heat exchange cylinder 4 and a steam-water communication pipe 6, and the heater body 1 The right side of the right side is connected to the inner wall pipe of the heating cylinder 3, the top of the heating cylinder 3 is connected to the bottom pipeline of the steam-water communication pipe 6, the top of the steam-water communication pipe 6 is connected to the bottom pipe of the heat exchange cylinder 4, and the outer wall of the heating cylinder 3 is socketed There is a thermal insulation component 7, the top of the inner wall of the heater body 1 is provided with an anti-fuse component 5, the bottom of the heating cylinder 3 is fixedly connected with the bottom of the inner wall of the heater body 1, and the top of the anti-fuse component 5 is fixedly installe...

Embodiment 2

[0047] Such as Figure 1-7 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, the inner sidewall of the airflow contact plate 8 is provided with a guide tube 11, and the outer wall of the guide tube 11 is fixedly connected to the inner sidewall of the airflow contact plate 8 , the left side of the guide pipe 11 is provided with an angular baffle block 10, the outer wall of the angular baffle block 10 is embedded and connected with the inner wall of the guide pipe 11, and the angular baffle block 10 is used to block the water flow existing on the surface of the airflow contact plate 8 , and the water flow is introduced into the collection box 22 through the guide pipe 11, the inner wall of the airflow contact plate 8 is provided with a flow hole 9, the inner wall of the airflow contact plate 8 is fixedly equipped with an active carbon filter screen 26, and the two ends of the active carbon filter screen 26 are all connected t...

Embodiment 3

[0049] Second aspect, such as Figure 1-7 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a method for a gas-electric dual-purpose heat pipe heater for oilfield wellhead heating, comprising the following steps:

[0050] Step 1: When natural gas is used as fuel or heated by an electric heating system, the energy is transferred to the heating cylinder 3 after being processed by the heater body 1, and the heat generated flows into the heat exchange cylinder 4 through the steam-water connecting pipe 6, thereby achieving the generation of the effect of heat;

[0051] Step 2: During the heating process of the heating cylinder 3, the heat generated will heat the heat conduction ring 14, and at the same time, heat the liquid inside the water flow reserved chamber 16, so that the waste heat existing on the surface of the heating cylinder 3 can be used to increase its service life ;

[0052] Step 3: When the temperature inside the heater body 1 ...

Abstract

The invention discloses a gas-electricity dual-purpose heat pipe heater and method for heating an oilfield wellhead, and relates to the technical field of petroleum extraction devices. The gas-electricity dual-purpose heat pipe heater comprises a heater body, a burner, a heating cylinder, a heat exchange cylinder and a steam-water communicating pipe, wherein the right side of the heater body is connected with an inner wall pipeline of the heating cylinder, the top of the heating cylinder is connected with a bottom pipeline of the steam-water communicating pipe, the top of the steam-water communicating pipe is connected with a bottom pipeline of the heat exchange cylinder, the outer wall of the heating cylinder is sleeved with a heat preservation assembly, and an anti-fusing assembly is arranged at the top of the inner wall of the heater body. According to the gas-electricity dual-purpose heat pipe heater and method for heating the oilfield wellhead, an airflow adsorption machine is matched with an airflow contact plate, so that gas inside the heater body can be replaced with the outside, the problem that part of parts are fused due to the fact that the temperature inside the heater body is too high is solved, the phenomenon that the internal temperature of the heater body is still high after the work is finished is avoided, and the temperature inside the heater body can be freely controlled under the action of the airflow adsorption machine.

Description

technical field [0001] The invention relates to the technical field of oil extraction devices, in particular to a gas-electric dual-purpose heat pipe heater and a method for heating wellheads in oil fields. Background technique [0002] In order to meet the gathering and transportation requirements of oil production wells that are far away from the centralized processing station, oilfield companies have installed heating furnaces or heaters at the wellheads to heat crude oil to reduce the viscosity of crude oil and overcome long distances and excessive flow resistance. In order to meet the requirements of gathering and transportation, there are many types of these heating furnaces, the earlier ones have water jacket furnaces, and the recent ones have phase change or vacuum heating furnaces. There are following problems at prior art: [0003] 1. After the existing heater has been in operation for a long time, the internal temperature is high, and the heat cannot be discharge...
