Abstract: 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.
