间12断块微生物驱油工艺技术的应用

随着油田的开发,三次采油技术越来越多地应用于矿场试验。近年来,微生物采油技术也得到不断的完善,从单井吞吐发展到微生物水驱,该项技术已趋于成熟。详述了微生物水驱的机理,以及微生物的室内筛选评价和矿场应用效果。认为微生物水驱优于单井吞吐,驱油效率高,处理区域广,并同时作用于油水井,有较好的增注效果。且投入产出比高,经济效益好。

Application of Microbe Drive Technology in Jian 12 Block

With the development of an oil field, more and more tertiary recovery technologies have been put into field test. Microbe recovery technology has also been made perfectly vecently. The technology is developed from single well gulp and puff to microbe drive, so that it has been a ripe technology. The paper details the microbe drive mechanism, the evaluation of laboratory screening test and the field application result. It is believed that the microbe drive is better than the single well gulp and puff because the previous one has higher sweep efficiency and large treatment area. It has actions in both oil and water wells. The water injecti on offiiency can be improved after a flooding well is treated. The result shows better benefits for operators.
