Abstract

The invention discloses a gas-fired heater for oil-gas separation. The key points of the technical scheme of the invention are that the gas-fired heater for oil-gas separation comprises a gas heater and a filter, wherein the upper end of an oil-gas separation chamber of the gas heater is led out of a gas pipeline to be connected with a gas inlet of the filter; the lower end of a heat conducting cavity of the gas heater is led out of the gas pipeline to be connected with a gas outlet of the filter; the middle part of the gas heater is provided with the heat conducting cavity; the outer edge of the heat conducting cavity is provided with the oil-gas separation chamber; the oil-gas separation chamber is separated from the heat conducting cavity through a heat conducting pipe. According to the gas heater, the problem of separation equipment heated by using crude oil or the problem of a gas source for heating gas is solved, and further the problem of crude oil heating of oil delivery pipelines of edge wells and single wells is solved.

Description

Technical field [0001] The invention relates to a heating device for oil and gas separation, in particular to a gas heater for oil and gas separation. Background technique [0002] The oil in the oil pipeline in the oil field needs to be heated when the temperature is low. In the past, electric heaters were used to heat the oil in the pipeline. Recently, gas heaters have appeared, which use the associated gas in the casing to heat the crude oil, avoiding the accompanying gas in the casing. The emission of anger into the air causes a waste of resources and saves electricity. However, in view of the shortage of casing gas in old oil wells in my country’s oil fields for many years, it is impossible to use casing gas as an energy source for heating crude oil in pipelines. It is necessary to develop gas heaters for oil and gas separation to solve the current problem of edge wells and single The problem of the heat source for heating the crude oil in the well. Summary of the invention...
