【Abstract】 Cased Hole Formation Resistivity Logging(CHFR) is a new resistivity tool in cased holes developed by Schlumberger company. The CHFR’s measuring theory and specifications, cement′s effects on CHFR values and their corrections are introduced. Applications in some oilfields in China are described in detail, which include identification of "dead oil zone", qualitative evaluation of flooded reservoirs and quantitative computation of residual oil saturation. Log examples show that CHFR logging has better practical result and will be widely used in casedhole logging evaluations.更多还原
