A REVIEW ON ACID FRACTURING TECHNOLOGY IN CARBONATESTONE RESERVOIRS

本文综述了二氧化碳腐蚀的机理，分析了钢铁材料、ＣＯ２分压、温度、介质组成、ｐＨ、流速、钢铁表面膜和载荷等对二氧化碳腐蚀的影响，介绍了二氧化碳腐蚀的研究水平和研究趋势。

This is a review article on various acid fracturing technologies for carbonatestone reservoirs. The distinction between acid fracturing (fracturing acidization) and (matrix) acidizing is introduced. The acid fracturing technologies are divided into two classes: ordinary and depth. Nine types of depth acid facturing technologies are presented and discussed: pad acid fracturing, fracturing with gelled, chemically retarded, foamed, emulsified, and in situ crosslinked gelled acids, multifluid acid fracturing, closed fracture acidizing and equilibrium acid fracturing.
