简介了美国Apollo分离技术公司的酶解堵剂greengyme的生产原理和性能特点 ,初步探讨了解除出砂稠油井堵塞的机理 (greengyme的主要作用是将造成堵塞的细砂与稠油充分分离 ) ,介绍了现场解堵时的选井条件、酶解堵剂用量、施工工艺 ,永 8 5 2井基本情况和酶解堵施工效果。永 8 5 2稠油井在实施机械防砂后 ,产出的稠油与细砂混合造成堵塞而不能正常生产 ,用酶解堵后日产液、日产油、动液面大幅上升 ,含水急剧下降 (由 30 %～ 5 0 %降至4%～ 2 %)。
The production principle and performance characteristics of the greengyme, an enzymatic decontamination agent from Apollo Separation Technology Company, were introduced. The mechanism of decontamination of heavy oil wells in sands was primarily discussed (the main role of greengyme was to separate the fine sand and heavy oil that caused the blockage) This paper introduces the well selection conditions, the dosage of enzyme blocking agent, the construction technology, the basic conditions of Yong 8 5 2 well and the construction effect of enzymatic plugging. Yong 8 5 2 heavy oil wells in the implementation of mechanical sand control, the output of heavy oil mixed with fine sand caused by clogging and can not be normal production, with the enzymatic plugging after the Nissan liquid, Nissan oil, moving liquid level rose sharply, water drastic decline 30% ~ 50% down to 4% ~ 2%).
