摘要
For the characteristics that the reserves produced degree and development effect of Ordovician fractured-cavity carbonate rock reservoirs in Tahe oilfield decrease gradually,we use vertical of Karstification and the sublevel development of Well,first proposed definition of dense layer in fractured-cavity reservoir.And using drilling core,well logging,vertical of Karstification development behavioral characteristics and seismic wave impedance inversion method,established the distinction criterion of resistive dense layer,studied the distribution of different dense layer in Tahe six & seven district.This technique has been applied to the Tahe Oilfield Development,and it has become one of the most useful methods of fine reservoir description and producing degree of reserves during the current 12th Five-Year Plan.
