Making use of the ideas and methods for interpretation of cracks,the authors employed the multi-information gravity and magnetic and remote sensing technology. The concept of linear body field of remote sensing was introduced into the interpretation of linear anomalies and linear structures of the geophysical field. The study areas are two carbonate oil fields: the Zhanazhol, Kenkiyak oilfields located in the east part of Precaspian Basin, western Kazakhstan, and the Yurubcheno-Tokhomskoye oilfields located in the west of Baykit Basin in eastern Siberia. The characterization significance of macro-cracks and fractures of the geophysical linear body is explained, the quantitative method is analyzed, the distribution features of the geophysical field and linear body of Aktobe region are studied,and the development pattern of macro-cracks in this area is established.
