Water Cut Rising Rules on Block Fracture Reservoir with Bottom Water and Measure to Stabilize Oil Production and Control Water Cut

It is a fundamental work for stabilizing oil production,controlling water cut and improving the whole developing effect to properly recognize and forecast oilfield water cut raising rules.X oilfield belongs to type of reef stratigraphic trap block reservoir with fracture,sufficient power of bottom water and high oil water viscosity ratio.Early water breakthrough and high rate of water cut are main recovery characteristics.On a basis of PVT and dynamic data in the oilfield,water cut increase rules are deeply researched shows that whole coning control can greatly enhance oil production rate,reduce the rate of water cut and effectively improve oilfield development effect,which is of importance for X oilfield to make out measure to stabilize oil production and control water cut and for development of other similar oilfields.
