目前微生物单井处理技术已在胜利油田广泛应用,但其选井条件还需要进一步完善。利用自制的油套环空模拟器,加入同比缩小量的菌液,观察在不同油井沉没度时细菌运动规律,掌握在不同油井沉没度时细菌运移到抽油泵吸入口的时间,从而优化了微生物单井处理技术的选井条件。微生物单井处理技术应选择沉没度为300～800m沉没度的油井。 At present, single-well microbial treatment technology has been widely used in Shengli Oilfield, but its well selection conditions need to be further improved. By using homemade oil loop annihilation simulator, the amount of bacteria in the reduced volume was added to observe the movement of bacteria in different submerged wells, and the time that the bacteria migrated to the suction port of the pump when different submerged wells were grasped to optimize Well selection conditions for single-well microbial treatment. Microbial single-well treatment technology should be selected sunk degree of 300 ~ 800m sunk well.
