Energy-saving and carbon-reducing process for oil field steam-injection boiler

Abstract

The invention discloses an energy-saving and carbon-reducing process for an oil field steam-injection boiler, and particularly relates to the technical field of oil field processing, which comprises the following steps of: 1, inputting water entering the boiler into a flow guide pipe through a multi-stage centrifugal pump to accelerate and self-clean an inlet; 2, inputting the accelerated water in the step 1 into a comprehensive processor for cluster breaking and chemical combination treatment; thirdly, sacrificial anodic protection treatment is conducted on the water subjected to cluster breaking and chemical combination in the second step; 4, enabling the liquid treated in the step 3 to flow through a magnetic line field for physical key breaking treatment; and 5, inputting the water treated by the magnetic line field in the step 4 into an oil field steam-injection boiler for use through parallel rectification. Passive energy absorption of water molecules is changed into active energy absorption; through three-stage treatment of the comprehensive treater, the sacrificial anode protection and the magnetic line field, cluster breaking and chemical combination of water are realized, generation of adsorptive and superimposed scales can be prevented, oil-water compatibility can be improved, and oil-water fluidity can be improved.

Description

technical field [0001] The invention relates to the technical field of oilfield processing, and more specifically, the invention relates to an energy-saving and carbon-reducing technology for an oilfield steam injection boiler and a processing technology thereof. Background technique [0002] With the increasing shortage of national oil resources, the scale of heavy oil development and production has increased accordingly. The use of hot steam huff and puff technology to develop heavy oil is one of the main forms of heavy oil production at home and abroad. The principle of this technology is to use a wet steam generator to generate high-temperature and high-pressure hot steam. The hot steam is injected into the oil-bearing formation, heating the formation to make the viscous oil thinner, and then extracted. The special steam injection boiler for oil field is the key equipment for the thermal recovery of heavy oil, and the safe operation of the steam injection boiler has beco...
