摘要
Abstract
The types of oil and gas reservoirs in Qinghai oilfield are abundant with obvious the geological characteristic differences and different development modes and development status,so the process of saturation logging in cased hole should be applied for reservoir conditions.At present,PNN pulse neutron and PSSL full spectrum logging are mainly used in Qinghai oilfield through nuclear logging,the annual logging capacity is about 80 wells.Through the application of more than 600 w ells,T he mature saturation logging technology and interpretation method of four kinds of typical oil and gas reservoirs are gradually formed.In the middle and high water flooded oilfield,this paper proposes a method of combination of capture cross section interface curve in PNN logging and the compensated neutron curves for the purpose of qualitative identification of watered out layers.In low salinity oilfield,oil and water layer identification uses carbon oxygen logging in PSSL;In low resistivity gas field,gas and water layer interpretation uses PNN and PSSL;PNN time lapse logging is used to monitor the gas-liquid interface migration in gas injection oilfield,w hich provides a scientific basis for the development of oilfield.关键词
