摘要

热气酸解堵技术是同时利用酸、热、气、表面活性剂可生成泡沫酸的酸化解堵技术。简要叙述了热气酸解堵的作用机理和在大庆油田的应用情况。结合现场实际,讨论了热气酸解堵技术对注水井近井污染解堵的适应性,对在砂岩地层条件下的选井选层、施工工艺等方面作了总结与分析,并取得了初步的认识。

Abstract

This paper briefly describes the plug removal mechanism of hot gas acid and its application in Daqing oil field. Based on the field application, this paper discusses the suitability of the technology to remove the near wellbore contamination. This paper also sums up and analyzes the well selection, layer selection, operation technology and so on when treating sandstone formation.
