摘　　要：哈拉哈塘地区位于塔北隆起轮南低凸起上,该地区具有良好的油源条件,是塔北地区近期油气勘探的重点区带。目前在哈拉哈塘地区已部署钻井上百余口,普遍在二叠系都钻遇火成岩,厚度变化大,岩性变化复杂,严重影响到本区的油气勘探进程。本文利用多属性分析技术对该地区火山岩的断裂构造进行了研究,研究发现基于波阻抗反演的相干属性、到下一个CDP相关时窗的滑动时间属性以及相关长度属性对工区内的地质构造反应敏感,可以清楚地呈现出构造的形态。在此基础上,对三种敏感属性进行叠合分析,叠合图融合了各属性的优势,使构造结构得到了更加清晰的刻画。HLHT area,located in Lunnan low uplift of Tabei uplift,has good conditions for oil source, and recently it＇s the focused band of Tabei area to exploit oil and gas resource. At present, there have been more than one hundred wells deployed in HLHA area,which commonly encounter igneous rocks. Seriously, the igneous rocks affect the process of oil and gas exploration, which have a big variation in thickness and complex changes in lithology. In this paper, a multi-attribute analysis technology is used for predicting fractures in the area. The results show that the ESP Based on Impedance Inversion, Correlation Window Time Shift to Next CDP and Correlation Length are sensitive attributes to the geological structures in work area, which can show the morphology of configuration clearly. On this basis, the three sensitive attributes are analysized in a superimposed way, which fuses the advantages of each attribute and portrays tectonic structures more clearly.
