Zhangtianqu oilfield locates in the center of Yixia west slope, Ordos Basin. The field has a complex hydrocarbon-bearing bed set. On principle that lithology and reservoir can be identified, geologic parameters such as shale content, porosity, and oil saturation can be determined and be used to distinguish oil-bearing formation from water formation, as well as costeffectiveness, an improved logging interpretation model has been established. The model extends conventional single porosity interpretation methodology to identify various lithologies (such as coal seam, radioactive sandstone, carbonate rock besides sandstone and shale) by comprehensively analyzing the logging responses of sand reservoirs on economic logging set of acoustic logs and induction logs. Applications on real data show the improved model is superior in identifying complex lithology with conventional logging data.

张天渠油田位于鄂尔多斯盆地伊陕斜坡西部中段，该油田含油层系复杂，在岩性地质特征分析时，本着&能确定岩性，划分储层，提供泥质含量，孔隙度，含油饱和度等地质参数，区分油层，水层，以及经济适用&的原则，选用经济适用的声感组合测井系列，通过综合分析砂岩储层的测井响应特征，对传统单孔隙度解释方法进行改进，增加识别多种岩性成份(除砂岩，泥岩外，局部含有煤岩，放射性砂岩，碳酸盐岩等复杂岩性)的功能，建立了适合该油田的测井解释模型，提高了利用常规测井资料识别复杂岩性的能力和测井参数的解释精度，为油田勘探开发提供依据。
