Recognizing watered-out zones by using traditional well logs

SONG Zi qi, ZHAO Lei, WANG Rui fei, et al (College of Petroleum Engineering, Xi'an Shiyou University, Xi'an 710065, Shaanxi, China)  
The techniques and characteristics of recognizing watered out zones by using natural potential log, resistivity, dual frequency dielectric, induced polarization, acoustic move out, neutron gammar ray, natural gammar ray, thermal neutron lifetime and carbon to oxygen ratio log curves are presented. The recognition of the watered out zones of sand shale profile and old cased well is discussed according to the characteristics of single log curve and the compound characteristics of several log curves.
