摘要

介绍了液体转向酸化技术的转向机理,转向酸化室内静态试验和动态流动模拟试验成果,以及该技术在现场的应用情况。结果表明:液体转向酸化技术是改善注水井(油井)的吸水剖面(产油剖面),实现均匀布酸的极为有效的手段。

Abstract

This paper introduces the steering mechanism of the liquid steering acidizing technique,the results of the static lab experiment of steering acidizing and the simulation experiment of dynamic now,as well as the field application of the technique. Field application results indicate:the liquid steering acidizing technique is a very effective means for improving the injectivity profile (oil producing profile)of the injectors (producers) and distributing the acids evenly.
