China Petroleum & Chemical News Network reported that a long shut-in well that has been shut in for more than 10 years, after the "multi-stage temporary plugging and staged fracturing process" by the scientific research personnel of the Fracture Institute of Shengli Petroleum Engineering Technology Research Institute, has recently revived and achieved the highest daily oil production.
The 15-ton increase in production has successfully realized the stop of the old well
.
Well Yong 1-45 is a long-stop well in Yongan Oilfield of Dongxin Oil Production Plant
.
The well was fractured and put into production in June 2000, and ceased production in December 2010, with a cumulative output of 13,000 tons of fluid and 9,600 tons of oil.
This technology can deliver high-strength water-soluble temporary plugging agents into the interval one or more times to form a filter cake to temporarily plug the previous fractures, forcing one or more new fractures to be opened in the interval, thereby achieving better performance than conventional fracturing.
Larger single well productivity can also realize natural selection of fill points and separate transformation of multiple sections
.
During the on-site implementation, the technicians evaluated the longitudinal reservoir oiliness, energy distribution, effectiveness of injection-production well groups, and in-situ stress steering, etc.
At present, the well has been pumped for 3 months, with a daily output of 17.
3 tons of fluid and 13.
1 tons of daily oil.
The cumulative oil production is nearly 1,000 tons, and the effect is gratifying
