Abstract

The invention discloses a steam injection boiler and an anti-explosion method and device thereof. The steam injection boiler comprises a furnace chamber, an ignition part, a gas conveying pipe, a flow meter and a controller. The furnace chamber is used for providing a burning place of combustible gas. The ignition part is used for igniting combustible gas in the furnace chamber. The gas conveying pipe is used for inputting the combustible gas into the furnace chamber. The gas conveying pipe is communicated into the furnace chamber. The flow meter is arranged on the gas conveying pipe. The flow meter is used for measuring gas flow in the gas conveying pipe when the steam injection boiler is not ignited. The controller is connected with the flow meter and can obtain the gas flow in the gas conveying pipe measured by the flow meter. When the gas flow obtained by the controller is not smaller than 50 cubic meters per hour, the control can forbid ignition of the ignition part. According to the steam injection boiler and the anti-explosion method and device thereof, the problem that in the prior art, potential safety hazards generated by combustible gas leakage of a steam injection boiler can be effectively solved.

Description

technical field [0001] The present application relates to the field of oil exploitation, in particular to a steam injection boiler and its explosion-proof method and device. Background technique [0002] At present, steam oil recovery is a technology widely used in the exploitation of heavy oil and super heavy oil. Steam oil recovery is to inject saturated steam into the oil layer to heat the oil layer, so that the viscosity of the heavy oil is reduced and it is easy to flow, and the injected steam can Provide driving force for heavy oil to flow into the wellbore. The steam required for steam injection oil recovery is produced by burning fuel in a steam injection boiler to heat water. [0003] The fuel of the steam injection boiler is usually natural gas, and its structure usually includes a furnace, an ignition part, a gas pipeline and a gas source. The ignition part protrudes into the furnace to ignite the combustible gas in the furnace. The gas delivery pipe can transp...
