Abstract: In view of the problems of ND 26 well block in Ningdong oilfield after a long-term shutdown, such as the formation energy recovery, the pressure distribution and the productivity change, the research on the formation energy recovery degree, the pressure distribution regularity and the trial production characteristics during the shutdown period was carried out by comprehensive application of reservoir engineering and other methods. The results show that the formation pressure gradually recovers during the shutdown period. During the shutdown period, the formation fluid was redistributed and the remaining oil was enriched towards the high part of the structure. The oil-water interface had been raised by 10.0 m compared with the original state. The output of the reproducing wells at the high part of the structure recovered quickly and the water cut increased by a small margin. The shutdown and re-production of oil well not only save the energy and reduce the consumption, but also not change the final recovery rate of oil field. Besides that, it is helpful to restore the formation energy and prolong the development life of oilfield.
