| Abstract: | The principle for well selection is introduced for using the technique of temporary plugging and acidization, the equation for the dosage of acid fluid and temporary plugging agent is given. A core evaluating test is conducted on the selected plugging agent, and its dissolution and temporary plugging intensity are detected. Field operations are made on 5 wells with success rate of 100%, the plugging efficiency is 87. 3%. |
