Biological plugging agent BD-II is a biological oil field flooding product based on biosurfactants. It can be used alone or in binary and ternary composite oil displacement systems. It improves oil displacement efficiency by emulsifying remaining oil, improving wettability, reducing oil-water interfacial tension, expanding water flooding sweep volume, etc., and further Improve oil recovery.
Biological plugging agent BD-I is a biological oilfield deblocking product with biosurfactant as the main component. It can be used to remove plugging in oil wells and reduce pressure and increase injection in water injection wells. The oil well unblocking operation method does not move the production pipe string, squeezes in from the oil casing annulus, and starts pumping production after the well is blocked. The method of depressurizing and increasing injection of water wells is to use a high-pressure plunger pump to pump the deblocking agent into the formation along with the injected water.
