The characteristics and identification of “oil bright spot” in Chepaizi

The hydrocarbon exploration in the east of China has developed to that of subtle reservoir. The geophysical technique as the key exploration method of subtle reservoir focuses on identifying and describing reservoir, especially on sand body. For the continental facies fault basin with various complex subtle reservoirs, a series of techniques suitable for channel sand body, glutenite, turbidite, beach bar, stratigraphy, complex buried hill and so on have been developed and applied in the subtle reservoir identification and description and have made great progress in actual exploration.
