Based on analysing sedimentary characteristics of the Chang 6 oil bearingbeds in the Chuankou oil field, the author has studied petrological characteristics,diagenesis and porosity structure and suggest that the evolution of the environment during deposition the Chang 6 oil bearing beds represents the history when the water platform delta was gradually transformed into a terrestrial plain.

Chuankou oil field in North Shaanxi is made of the Chang 6 oil bearing formation of the Yanchang group in the upper Triassic, which was filled with the sedimentary sequences in sandstone and mudstone check.
