Coalbed gas development was made great success in Dacheng highs within Cangxian uplift. As the same setting, on the southern parts of Cangxian uplift, coaly beds in upper Paleozoic are preserved in good condition and stable distribution in Dagang fields. The coaly beds area less than 2 000 m is about 1 500 km2. The estimate of benefit coalbed gas resources is 3 228×108 m3, so that there is great potential of coalbed gas in Dagang oil field.
Key words: Cangxian uplift; Dagang fields; Coalbed gas; Gas content; Gas saturation; Permeability.
