摘　　要：冀东油田高尚堡中深层和柳赞深层原油含蜡量高,区块大部分油井属于低产低效油井,井筒结蜡严重,热洗作业频繁,造成地层污染严重,而且清蜡费用高。从20世纪90年代开始,油田逐步采用了微生物清防蜡技术。室内分析和现场监测表明,微生物能够有效降解石蜡,阻止蜡晶生长;抽油机负荷和回压明显降低,减少检泵次数,延长免修期,对油井的正常生产有较好的维护作用。The crude oil from Gaoshangbao middle and deep deposits in Jidong Oil Field contains higher amount of paraffin and most the wells are low production wells.The well tubing with heavy wax deposition need to be frequently hot washed,which pollutes the strata and the cleaning cost is high.Ever since 1990s ,the microbial wax - removing technology has been applied in the oil field. Both indoor analysis and outdoor monitoring results have confirmed that the microbial has effectively decomposed wax formation and pr...
