Logging Characteristics and Identification Methods of Low Resistivity Oil Layer: Upper Cretaceous of the Third Member of Qingshankou Formation, Daqingzijing Area, Songliao Basin, China

<div>Standard identification of calcareous interlayers (sharp-high amplitude logfacies). (a) Cross plot of the parameters RILD and AC is invalid to identify low amplitude, middle amplitude, and sharp-high amplitude logfacies. (b) Cross plot of the parameters JRT and JAC is effective to identify sharp-high amplitude type from those three logfacies.</div>
