Abstract:

Karamay Oilfield has been producing many years with water injection，by cased hole formation resistivity logging，the potential netpay reservoirs can be explored，improvement of reservoir recovery put forward.The authors analyze over 20 welllogging data of northwest and east oilfield of Junggar Basin，the main influencing factors of the cased hole formation resistivity logging application include vibrating of instrument while measuring，cementation quality，well bore waxing，case deformed，salinity of mud and injected water，the resolution on thinner layer，reservoir pollution etc..Based on the analysis of the application for lowpermeability sandstone and conglomerate reservoir，the authors give the conclusion，on the one hand，the heterogeneity of reservoir is key factor for evaluation on remaining oil，on the other hand，in general，measured interval should not be more than 400 meters.Although there are some shortness，it is believed that the casd hole formation resistivity logging application is prospective in Karamay Oilfield.

Key words: low permeable reservoir, cased hole formation resistivity logging, depletion index, remaining oil saturation, influencing factor, Junggar Basin 
