Abstract

Abstract

The Yichuan-Xunyi area lies on southeast margin of the Ordos Basin. Bore core and slice observation and accounting, along with image logging data analysis, reveal main E-W orthogonal fractures in the studied area. The study of homogenization temperature of fluid inclusions in fractures, sedimentary history, and structural evolution in the studied area indicates that the fractures of the Yanchang Formation was mainly formed at terminal Jurassic- Early Cretaceous. R/S fracture analysis, a useful method for prediction of fracture distribution, has been utilized to identify fractures distribution areas.
