| Abstract: |
| In order to develop the acid systems for three special lithology rocks containing Yi-2 well volcanic rocks, Liping-1 well limestone rocks and Xi-3-69 well dolomite-mud rocks from Chagan oilfield, the dissolution rates of different special lithology cores in different acids are measured to determine the main acids, then the acid addictives including corrosion inhibitor, iron stability agent, clay stabilizer and discharge aiding agent are selected. In this way the acid systems adapting for three special lithology rocks are developed and they all have good acidizing and retarding effects by measurement of dissolution rates |
| Key words: special lithology, dissolution rate, acidizing, acid addictive |
