微生物清防蜡技术在黄场油田的应用

摘要

Wax precipitation of crude oil is the main cause for decrease of oil production.In practical production,it is necessary to select appropriate wax removal technique in line with water cut of oil wells,sand production rate and wax precipitation to achieve economic and desirable effect in wax removal.Microbial strains preparations for wax removal can fully replace chemical agents and avoid the damage on the stratum in well cleanup,thus increasing oil production.%原油结蜡是引起油井减产的主要原因。在生产实践中,应根据油井的含水、出砂及结蜡等情况选用合适的清蜡防蜡技术,才能使清蜡防蜡收到经济满意的效果。微生物清防蜡菌种制剂是由多种好氧及兼性厌氧菌组成的石油轻烃降解菌混合菌,使用它完全可以取代化学剂,还可以避免洗井对地层的伤害,起到一定的增油效果。
