本文主要针对某油田有机堵塞严重,应用生物醇吞吐解堵技术进行现场试验,通过该药剂的亲水憎油特性,剥离岩石表面原油,改变固体润湿性,降低原油与岩石的界面张力,增大油流通道,试验初期单井日增液0.7t,日增油0.7t,现场试验取得了较好效果。
In this paper, aiming at the serious organic blockage in an oilfield, a field experiment was conducted using bio-alcohol swallow plugging technology. By virtue of the hydrophilic and oleophobic properties of the agent, the crude oil on the rock surface was stripped, the solid wettability was changed, the interfacial tension between the crude oil and the rock was decreased, Large oil flow channel, the initial single-well liquid test early 0.7t, increasing oil 0.7t, field tests achieved good results.
