相同或相近成熟度源岩形成的煤成气的甲烷及其同系物的δ~（13）C值比油型气的对应组份的δ~（13）C值重；

The δ ~ ( 13 ) C values of methane and its homologues of coaliferous gas are heavier than that of corresponding component of petroliferous gas from source rocks with the same or similar maturity .

浅层气藏是指埋藏深度小于1500m的气藏，主要包括生物气、煤成气、油型气、水溶气等。

Shallow gas reservoir is that buried depth is less than 1,500 meters , including biogas , coal formed gas , oil type gas and water soluble gas etc.

不同成因类型天然气的Ar40／Ar36比值、δ13C1值、甲烷同系物碳同位素组成以及氢同位素分布等地球化学指标，具有各自不同的特征，而且煤成气的组分以干气为主。

Different kinds of natural gas have different geochemistry characteristics which include Ar40 / Ar36 , δ 13C1 , carbon isotope of methane homologue and hydrogen isotope . The main composition of coal-formed gas is dry gas .

渤海湾盆地截止20世纪末已发现气田111个，探明气层天然气地质储量2716.98×108m3，按其成因分为下第三系烃源气和石炭&二叠系煤成气2种。

111 gas field have been found in Bohai Bay basin by the end of the twentieth century , Original natural gas reserves have been known to be 2 716.98 × 10 ~ 8 m ~ 3 , and is divided into petroliferous gas and Coal-derived gas according different origin .
