低渗透砂岩储层分步溶离酸化改造技术的研究及应用分析

摘要

本文以462井低渗透砂岩储层为例，制定出低渗透砂岩储层分步溶离酸化的改造技术，并且对其改造过程进行现场跟踪，最后做出综合评价。%A Stepwise resolution acidization technology in low permeability sandstone reservoir is presented in this paper citing the example of Well-462 along with the on site tracking on the process of upgrades to make a comprehensive evaluation.
