Some Dynamic Problems of Bottom Water Reservoirs Development in Qintong Depression,the North Jiangsu

Xinanzhuang oil field is a typical bottom water oil field of Qintong depression in north Jiangsu. Taking Xinanzhuang oil field as example,the paper makes dynamic analysis on critical production,bottom water coning,oil-water interface movement,and residual oil distribution during development and production of reservoirs with bottom water.It also makes proposals for further development and production of natural water drive reservoirs. Case history shows these can be a reference for the development of Qintong and similar reservoirs.
