Abstract

Geological reserves of natural gas in Xihu Sag for Donghai Basin,ZhuⅡ Depression for Pearl River Mouth Basin,Qiongdongnan Basin and Yinggehai Basin take up more than 70% of whole geological reserves of natural gas of offshore China.These basins and sags formed the gas-rich zone of offshore China.Gases in these basins or sags are mainly coal-formed gas.They were derived from humic or sapropelic-humic type source rocks.The main source rock is transitional coal-bearing source rocks,the secondary source rock is marine source rock whose organic matter mainly originated from terrestrial high plants.Paleoclimate in the Xihu Sag of Donghai Basin and northern South China Sea are wet and hot which is favorable for the terrestrial higher plants in the formation period of main source rocks.Under favorable climate,river-delta system is the main controlling factor for the formation of source rock of gas-rich zone in offshore China.River-delta system is favorable for the supply of nutritive material for the organisms,and the load of organic matter of terrestrial higher plants,and the formation of delta coal-bearing source rock and marine source rock.The development degree of river-delta system decides the development degree of source rock and its potential of hydrocarbon generation.
