摘　　要：横波资料在储集层识别、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,这给储集层研究带来了困难。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,建立了该地区横波时差参数计算模型,以期为同类储集层横波时差的计算提供参考。Shear-wave information play an important part in reservoir identification, engineering parameter calculation, geophysical prediction, etc. However, few S-wave data collected from the logging information lead to difficulties for the later studies on the reservoir. Taking the lithologic reservoir in Shengbei area of Tuha oilfield as an example, the relations of compensated neutron, compensated density, resistivity curves and the lithology in studying conventional logging data are conducted, by which the S-wave moveout data from existing standard wells are collected, and the model for moveout parameter calculation in this area is developed, in order to provide reference for such a calculation of similar reservoirs.
