摘　　要：针对七里村采油厂原油(延50-1,郑597-5)组分特点,进行清防蜡菌种选育,最终优选出适合采油厂油井生产的清防蜡菌种DM-1,并结合采油厂进行现场试验,总结出一套符合采油厂油井地质情况和蜡质特性的微生物清防蜡配方和施工工艺。现场应用结果表明,采用该项微生物清防蜡工艺能有效解决七里村油田的清防蜡问题,具有一定的推广应用价值。The microbial wax inhibition/removal technology was introduced using the group of microbe DM--1 selected according the components of wax--bearing crude oil and the properties of reservoir in qili--country oilfield. Applications in more 20 wells showed that the pump inspection period could be prolonged to two times and the average workover cost of single well is depressed more 1000 RMB which is lower 20-30% than that of using chemicals. The effects of paraffin inhibition and wax removal have been improved efficiently in this oilfield.
