Novel flue gas thermal oil recovery equipment

Abstract

The invention discloses novel flue gas thermal oil recovery equipment. The novel flue gas thermal oil recovery equipment comprises a waste heat recovery heat-exchange system, a flue gas pressurizing system, a cooling system, a purification filtering system, a gas mixing system and a flow adjusting and control system; an inlet of the waste heat recovery heat-exchange system communicates with a fluegas outlet of an engine; the flue gas pressurizing system is connected with the engine and connected with the waste heat recovery heat-exchange system; an outlet of the waste heat recovery heat-exchange system is sequentially connected with the cooling system and the purification filtering system; and an inlet of the gas mixing system is connected with a second flow path outlet of the waste heatrecovery heat-exchange system and the outlet of the flue gas pressurizing system, an inlet of the flow adjusting and control system is connected with the flue gas pressurizing system, and an outlet ofthe flow adjusting and control system is connected with the waste heat recovery heat-exchange system and the gas mixing system. The novel flue gas thermal oil recovery equipment utilizes flue gas generated by the engine in a power system of the novel flue gas thermal oil recovery equipment to be recovered for incremental oil production operation, a flue gas generation device is omitted, and energy reutilizing and zero emission of exhaust gas are achieved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment and oil recovery, in particular to a novel flue gas thermal oil recovery equipment. Background technique [0002] At present, oilfield flue gas drive technology has been widely used in oil production stimulation operations, but the conventional technology needs to provide a separate flue gas generating device (such as a boiler), purification device, cooling device, booster device (such as a diesel engine driven booster machine), etc., the power components of these devices not only need to consume a large amount of fossil fuels and produce high-temperature gas pollutants, but also have a relatively large structure and a relatively complicated process flow. At present, there is no literature report on the use of engine flue gas thermal injection well production. Contents of the invention [0003] The object of the present invention is to address the defects of the prior art, and provi...
