In this paper, the genetic types and origin of the found gases in the Liaodong Bay, Bohai Bay basin was studied. The results showed that the found gases in Liaodong Bay are mainly wet gas, and could be classified into two genetic types, which are petroliferous gas and humic-prone gas, based on δ¹³C. The two genetic types are correspond to organic materials of type Ⅱ₁ and type Ⅱ₂. The petroliferous gas distributes in hydrocarbon fields of JZ21-1, JZ25-1 and JZ25-1S.And the humic-prone gas distributes in JZ20-2 hydrocarbon field. It is concluded that the source rocks with bigger than 0.6% (Ro) in Liaodong Bay area could serve as effective gas source rocks.
