Oil field well mouth gas-electricity dual-purpose heat pipe heater and method

Abstract

The invention discloses an oil field well mouth gas-electricity dual-purpose heat pipe heater and method. The heat pipe heater comprises a fuel gas heating system taking fuel gas heating as a main heating mode, an electric heating system taking electric heating as an auxiliary heating mode and a heat exchange system, wherein the fuel gas heating system and the electric heating system are compatible with each other, the fuel gas heating system comprises a heating body assembly of a full-wet-back smoke two-return-stroke structure, the electric heating system comprises an electric heating pipe, the heat exchange system comprises a heat exchange assembly, the heating body assembly and the electric heating pipe share a heating cylinder, and the upper part of the heating cylinder is jointly connected with a heat exchange cylinder where the heat exchange assembly is located so as to form the heat pipe heater with a circulating heat exchange function. According to the heat pipe heater, the reliability of the heat pipe heater can be effectively improved, the service life of the heat pipe heater can be effectively prolonged, the fuel gas heating system and the electric heating system can be used for heating independently and compatibly, and the heat pipe heater is high in heat energy utilization rate, light in size design and capable of meeting related environment-friendly emission standards.

Description

technical field [0001] The invention relates to the field of oil extraction devices, in particular to an oilfield wellhead gas-electric dual-purpose heat pipe heater and a method thereof. Background technique [0002] At present, 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 / devices at the wellheads to heat crude oil to reduce the viscosity of crude oil and overcome long distances and excessive flow resistance. , so as to meet the collection and transportation requirements. 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. Conform to the concept of environmental protection development, and all solve a single problem, the applicability, universality and application range are not wide. [0003] For example, the fuel gas...

AI Technical Summary

Problems solved by technology

[0005] 1. It is not possible to use two or more energy sources of associated gas and electricity for complementary utilization. When the associated gas source is insufficient, the heating furnace will be in a shutdown state

[0006] 2. The heat utilization rate of the traditional heating furnace is low, and the heat utilization rate is generally 60-70%, resulting in energy loss

[0007] 3. Most of the heating furnaces are large in size, and the internal structure does not use enhanced heat transfer elements, which are bulky, not compact, and high in operating costs.

[0008] 4. The exhaust gas produced by the heater, such as particulate matter, sulfur dioxide, nitrogen oxides, etc., is not up to standard and is restricted for use
