摘　　要：横波资料在储层识别、工程参数计算、地球物理预测等方面具有非常重要的作用,但通过测井资料采集到的横波资料很少,这给储层后期研究带来了困难。以吐哈油田胜北地区岩性油气藏为例,在研究常规测井资料中补偿中子、补偿密度和电阻率曲线特征与岩性关系的基础上,通过提取现有标准井横波时差资料,建立该地区横波时差参数计算模型,以期为同类储层横波时差的计算提供参考。Shear- wave data plays a very important part in reservoir identification, engineering parameter calcula- tions, geophysical prediction, etc.. However, logging data collected from the logging information is little, which leads to difficulties for the later studies on the reservoir. Take the lithological reservoir in Shengbei area of Tuha oil- field as an example, based on the relations of compensated neutron, compensated density, resistivity curves and the lithology in studying conventional logging data, through collecting the shear - wave slowness data of existing stand- ard wells, parameter calculation model on shear- wave slowness in the region is established, it provides reference for the calculation of shear - wave slowness of similar reservoirs.
