阿波罗生物酶解堵技术在百色油田的应用

百色油田部分油井出砂、乳化、结蜡严重,地层存在堵塞现象,部分油井因井况、出砂等原因无法使用常规酸化解堵技术,因此引进较为新型的阿波罗生物酶解堵技术。通过对阿波罗生物酶解堵剂的作用机理进行分析探讨后,采用不动管柱施工方法,在百色油田13口油井上进行了14次施工,有12井次取得解堵增油效果,措施有效率达85.7%,累计增油270.6t,投入为32.5万元,产出为56.5万元,投入产出比为1∶1.74。

Application of Apollo Greenzyme Unblocking Technique in Baise Oilfield

It is serious in Baise oilfield that partial oil wells make sand flow,emulsification and wax deposit with formation plugging in oil layers.Conventional acidizing treatment can not be used in some oil wells because of the bad well condition and sand production.So Apollo Greenzyme unblocking techniques are introduced to apply in Baise.This paper gives a way of operating with original production string after analyzing and discussing the working mechanism of Greenzyme unblocking agent,14 experiments are done including 13 wells,of which 12 get the effect of unblocking and the increasing oil production.The efficiency of stimulation is 85.7% and the incremental oil arrives at 270.6t.Since the investment is 325000 yuan and the incoming is 565000 yuan,the input/output reaches 1:1.74.
