摘　　要： 套管钻井测井系列和测井环境与裸眼井相比发生了很大的变化,必须研究新的解释模型和评价方法。分析了套管钻井测井资料在储层中的响应特征,对比分析了裸眼井与套管井测井资料之间的响应关系,提出了套管钻井测井资料的校正方法;利用套管井校正后的自然伽马、套管补偿中子、RMT测井资料,建立了储层泥质含量、孔隙度、流体饱和度参数模型;以裸眼井解释结论为基础,通过套管井计算的泥质含量、孔隙度和饱和度的交会图分析,建立了套管钻井测井储层流体定性、定量解释标准。通过对2口新钻套管钻井测井资料的处理,证实该方法是有效的。 Because of the well logging series and environment changes in casing drilling logging compared to open hole logging,it was necessary to study new interpretation methods and models for the casing drilling logging.The corresponding characteristics of the casing drilling logging data in the reservoirs were analyzed and corresponding relation of open hole logging and casing well logging data were contrasted,the method of correcting casing drilling logging was developed.A parameter model of shale content,porosity and saturation was established by using the corrected GR、CNL and RMT logging data.Through the analysis of the cross plot of shale content,porosity and saturation which calculated by the casing drilling logging data,the qualitative and quantitative interpretation standard for distinguishing reservoir fluid characters is established.The effectiveness of the method is demonstrated by processing the data in 2 new casing wells.
