Shuanghe Oil Mine has experienced more than 20 years of production and development. At present, it has entered the middle and late stage of development, and the ground is decayed too quickly, resulting in the continuous increase of low-yield and low-efficiency wells under the jurisdiction of the oil wells under its jurisdiction. Since the beginning of this year, the mine has actively carried out on-site tests of microbial biomass extraction and oil production technologies, targeted microbial strains have been specifically selected, and pilot tests have been conducted on six oil well-injected strains one after another.
Microbial PIP technology is a technology that enhances oil recovery by introducing or stimulating microorganisms that can survive in the reservoir. Microbial oil recovery is another new method to increase oil recovery after water flooding, chemical flooding and polymer flooding. Field tests have proved that this technology has both oil-enhancing and maintenance effects on oil wells and is an effective process technology. It affects the production of oil wells and oil wells that are poorly connected with wells through the metabolism of oil thickening and wax deposition. , to reduce the blocking of debris particles on the rock pores, degrade, metabolize and absorb paraffin and other substances, making the crude oil easy to flow and exploit. This technology effectively increases crude oil production and has a wide range of applications for low-permeability oil fields.
Microbial oil production in Henan oilfield has obviously injected new vitality into the Shuanghe oil field that has entered the high water content
Recently, a new type of micro-organisms has been used to perform oil extraction technology on six wells in the Shuanghe oil field in Henan Oilfield. The implementation of this technology has injected new vitality into the Shuanghe oil field that has entered the high water content. In the production cycle of the past 3 months, these oil wells have a significant effect of increasing oil.
