摘　　要：在实际地层中组成地层的骨架成分可能有多种,单一的解释模型可能不能反映地层的真实岩性,不能精确评价储层。地层组分分析根据物理模型和测井响应特征建立方程组,求取地层剖面和测井响应理论值。以地层组分分析得到的岩性剖面为模型,通过对理论测井曲线与实际测井曲线的误差进行归一化计算得到模型权系数,同时根据地区经验确立模型误差法和人工权系数法的组合方式。该方法在实际资料处理中取得了理想效果,达到了精细评价地层的目的。There might be a variety of frame components in actual formation,while a single interpretation model might not reflect the true lithology of the formation or accurately evaluate the reservoir.For formation component analysis,equations were established based on the physical model and the logging responses characteristics,by which the theoretical value of formation profiles and log responses were derived.In this paper,the lithology profile calculated from the formation component analysis was applied as a model,the model weight coefficients were calculated by normalizing the error of the theoretical curves and the measured curves,a combination mode of model error method and artificial weight coefficients method were established according to the regional experience.This method is used for data process,and good result is obtained,it is favorable for fine reservoir evaluation.
