Abstract
The Daqing oilfield was put into development in 1960. At present, it is in the late stage of ultra-high water cut period. Various displacement modes coexist, and the reservoir development and management is complex and difficult. In order to control the decline of production, the number of new drilling wells increases year by year, the surface and underground conditions are complex, and the management is difficult. The drilling shut in affects the production year by year. The formation pressure decreases greatly during the drilling shut in process, which affects the development situation. In order to reduce the impact of drilling shut in on production, control the decline of formation pressure, and explore the management methods and methods of drilling shut in. In order to reduce the impact of drilling shut in on production and control the decline of formation pressure, we explore the management methods of drilling shut in.
