Discussion of KCLMudAffecting onLog

Abstract

Abstract: During the drilling process, it is difficult to collect the log data when the cave-in takes place.KCl drilling mud is one of the methods to protect side-wall fromcollapsing, nevertheless it reduce the response of log curve to strata characteristics and is not favorable for well log evaluation. Based on the actual data ofLiaohe Oilfield, it analyses the property of KCl mud,studies the influence of KClmud to resistivity curve,GRspectrumcurve and GR curve and the correction methods for GRcurve, discusses the way to eliminate these effect, and provides the evidence to KCl mud logging evaluation.

Key words: Kcl mud, resistivity, spontaneous gamma;energy spectrumlog, affecting factors, corrected method
