摘要
中国天然气藏（田）以烃类气藏（田）为主，还有少量二氧化碳气藏和极少量硫化氢气藏；气藏中的天然气成因类型繁多，以油型气型和煤成气型为主，还有生物气型、混合气型、硫化氢气型和无机成因型。占全国气田、油气田总数不到13％的大、中型气藏（田）的储量占天然气总储量的70％以上。无机成因的二氧化碳气藏（田）分布在中国东部的渤海湾、松辽、苏北、三水、东海、珠江口、芬歌海等含油气盆地。气藏（田）主要发育干盆地的生气中。心及其周缘。
Chinese natural gas poo1s (fields) are chiefly hydrocarbon gas pools (fields), with a few of CO2 and a tiny of H2S ones. The gas genetic types are multiple, dominated by oil-type gas and coal-formed gas types, and then followed by other types such as the biogas, mixed gas, H2S-rich gas and abiogenetic gas etc.. The medium-large sized gas pools (fields), in number, account for only 13% of the total gas and oil-gas fields in China, but they possess more than 70% gas reserves of the total. The abiogenetic CO2 gas pools (fields) are mainly located in the eastern oil-gas bearing basins, such as the Bohai Bay, Songliao,Subei, Sanshui, East China Sea and Zhujiangkou basins etc.. Natural gas pools (fields) tend to develop in or surround the gas generation centers of sedimentary basins.
