摘　　要：我国高含蜡原油丰富。在原油采出的过程中,原油通过近井地带向井筒运移,温度逐渐下降,会造成石蜡结晶,石蜡从原油中析出,析出蜡聚集在近井地带,造成井筒的堵塞,这是引起油井减产的主要原因。保证高含蜡油井能够正常生产的重要手段之一是对油井实施有效地清防蜡措施。微生物清防蜡技术作为微生物采油技术的分支,其有许多突出的优点,如施工方法简单,作用周期较长,操作费用较低,不影响油的品质,对地层无任何污染伤害等。Waxy crude oil is very abundant in China. During the production of crude oil, the oil-gas migration from near wellbore area to well bore makes the oil temperature reduce, which can result in the precipitation of wax crystals, and precipitated wax crystals will deposit on the pipeline to cause blockage of the well bore. Therefore, to implement the measures of paraffin removal is the primary means to ensure the normal production of oil wells. Microbial treatment has many outstanding advantages： simple construction, low operating cost, long action cycle and so on.
