Problems solved by technology

[0004] Microbial enhanced oil recovery technology has produced good results in increasing production and efficiency, but there are still some limitations in specific operations: 1. Since bacterial reproduction requires a process, the effect is relatively slow
2. For relatively thick crude oil plugging removal, the effect of microbial oil recovery is general

Abstract

The invention provides a biological activator for a compound production promoter used in oil production. Based on the total weight of the biological activator, the biological activator comprises 15 to 30 percent of rhamnolipid, 10 to 30 percent of trehalose glycolipid, 4 to 25 percent of alkyl glycoside, and the balance of water. The biological activator of the invention has a certain water and crude oil solubility and good wettability on the surfaces of oil-containing rocks, can remove an oil film and disperse the crude oil, and possesses a strong crude oil emulsifying capability, and by a cooperation with microorganisms, the biological activator can achieve high applicability, long period of validity and rapid action effect.

Description

technical field [0001] The invention relates to the technical field of microbial oil recovery, in particular to a bioactive agent in a compound production-stimulating agent for oil recovery. Background technique [0002] Microbial Enhanced Oil Recovery (MEOR) is an important part of the four key technologies for enhanced oil recovery (chemical, thermal, gas flooding, and microorganisms), and its research began in the 1920s. The method of microbial enhanced oil recovery refers to Inject the microbial solution and nutrient solution isolated and cultivated on the ground into the oil layer, or simply inject the nutrient solution to activate the microorganisms in the oil layer, make them grow and reproduce in the oil layer, and produce metabolites that are beneficial to improve the recovery rate. By screening the characteristics of the bacteria, Function, function and adaptability, change the nature of crude oil and reservoir environment. Its main mechanism is to use microorgani...
