Problems solved by technology

This heating method mainly has the following problems: 1. The natural gas produced by a single well is unstable, and it cannot meet the heating needs of the oil storage tank from time to time.
2. The crude oil produced by a single well has high water content or high viscosity, and the furnace combustion is unstable. The furnace is often extinguished and the fuel pipe is often blocked, so the normal operation of the furnace cannot be guaranteed.
3. The temperature of the heat medium rises slowly, and the heat transfer is slow. The temperature of the crude oil in the oil storage tank cannot rise by one degree after heating for one day. It often happens that the oil truck comes and cannot put in the oil, and returns empty, causing the oil storage tank to be full and close the well, which is serious. Affect the normal production of oil wells

Embodiment Construction

[0014] In order to further disclose the technical solution of the present invention, below in conjunction with the accompanying drawings, the following examples are described in detail:

[0015] The invention consists of a coal-fired hot air heating furnace, a hot air circulation coil 11 and an oil storage tank 12, and is characterized in that the air outlet of the coal-fired hot air heating furnace is connected to the inlet of the hot air circulation coil of the oil storage tank through a hot air pipe and an induced draft fan , the outlet of the hot air circulation coil is connected with the air return port of the coal-fired hot air heating furnace.

[0016] When applying the present invention, at first open the flue gas regulating valve 8, start the stove, coal ash falls into the ash storage chamber 1, the flame of the combustion chamber 2 and the flue gas pass through the labyrinth exhaust flue 3, and the flue dust is filtered layer by layer, Regularly remove or backwash. T...

Abstract

An oil tank heated air circulation heating device comprises a coal hot-blast heater, a heated air circulation coil and an oil tank, characterized in that, the uptake of the coal hot-blast heater is connected with the heated air circulation coil inlet of the oil tank through the hot wind pipe and the draught fan, and the outlet of the heated air circulation coil pipe is connected with the air return hole of the coal hot-blast heater. The coal burning way is adopted for heating, which ensures to heat the oil tank normally. The heated air circulation furnace heats through the heated air circulation, which has fast rate of heat transfer, fast crude oil temperature rise and high thermal efficiency.

Description

1. Technical field [0001] The invention relates to a crude oil heating device for a single well pulling oil storage tank, in particular to a hot air circulation heating device for an oil storage tank. 2. Background technology [0002] At present, oil storage tanks are heated for single wells in oil fields, some are heated by hot water circulation, some are heated by superconducting liquid circulation, the heating furnace and oil storage tank are separated, and some are integrated, most of which are heated by natural gas or crude oil in the well. This heating method mainly has the following problems: 1. The natural gas produced by a single well is unstable, and it cannot meet the heating needs of the oil storage tank. 2. The crude oil produced by a single well has high water content or high viscosity, and the furnace combustion is unstable. The furnace is often extinguished and the fuel pipe is often blocked, so the normal operation of the furnace cannot be guaranteed. 3. Th...
