Abstract

In order to determine the drilling gas drainage radius, several different spacing drilling group were set up, and the relationship between drill pumping rate and the drainage time was solved through the relationships between drill gas flow and drainage time. Then on the basis of objective standards in line with drainage index for judging the pre-pumping rate, the drill group can be distinguished at the predetermined time to meet the target pre-drainage pumping rate, and the drilling gas drainage radius could be determined. By the field test study, it shows that the drill gas flow method is as practicable for measuring drainage radius.
