Abstract:

Four kinds of typical wells,namely paying,stripped,deficient,and barren wells are recognized in the Block 11 of Tahe oilfield through integrated research of geology,geophysics,and reservoir dynamics.A development plan,which gives first priority to paying wells followed by stripped wells,minimizes deficient wells and eliminates completely barren wells,was proposed based on an analysis of the specific geophysical features and performances of the reservoirs encountered by these wells.The practice shows that the plan is quite effective in improving drilling success ratio and economic returns.
