| 摘 要： | 钻井过程中,井壁垮塌时常发生,给资料录取带来困难,KCl钻井液是为了保护井壁而采取的一项措施,但是却降低了测井曲线对地层特性的反应,给测井评价造成了不利影响。从辽河油田实际资料出发,分析KCl钻井液特性,研究KCl钻井液对电阻率曲线、能谱曲线和对自然伽马的影响,以及自然伽马曲线的校正方法,探讨消除其影响的方法,为KCl钻井液测井评价提供依据。

| 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 from collapsing, nevertheless it reduce the response of log curve to strata characteristics and is not favorable for well log evaluation. Based on the actual data of Liaohe Oilfield, it analyses the property of KCl mud, studies the influence of KCl mud to resistivity curve, GR spectrum curve and GR curve and the correction methods for GR curve, discusses the way to eliminate these effect, and provides the evidence to KCl mud logging evaluation. |
