The research on tectonization intensity plays an important role in the analyses of basin evolution and hydrocarbon accumulation． At present，methods in this field are almost qualitative，and the quantitative one is still rarely reported． In this study，a quantitative research method for tectonization intensity is proposed． The research result on Tahe-Lunnan oilfield shows that this method can not only quantitatively express the tectonization intensity，but also qualitatively reflect the macroscopic deform property and the evolution history of strata． Therefore，it is an effective method for analyzing the characteristics of tectonization． In addition，the realization of the method also can provide qualitative information for studying the influence and control of tectonization on hydrocarbon accumulation．
