Abstract:

Structural fractures are not only seepage paths but also space for oil in metamorphic buried hill reservoirs. The theory of extending structure，isotopic dating, analysis of inclusion is applied to predict the forming period of fractures, then a better illustration for distributing characters of structural fractures in the margin of Liaohe basin is given, so good base for predicting the distribution of structural fractures in reservoir formation is made.

Key words: metamorphic buried hill reservoir, theory of extending structure, isotopic dating, analysis of inclusion, prediction of fracture
