STUDY ON MICROBIAL BUFF AND PUFF TESTING OF GUAN69-19 WELL

According to the stratum character of Guan69-19 well, a best-liking high temperature(65~100℃) bacterium and a new nutriment system aim at high salt oil reservoir have been filtrated out through improving on the traditional methods of filtrating petroleum microorganism. Using the bacterium, wellbore and near wellbore area microbial testing has been done to validate the effect. The accumulate experience for the cosmically application on high temperature and high salt oil reservoir. The result indicates that the production has been rise from 3.17 tons per day to 5.3 or 5.04 tons per day. All that shows the testing is successful and it will be benefit to expand application in high temperature and high salt oil reservoir.
