IMPORTANCE OF ZHUJIADUN GAS FIELD RESERVOIR RESEARCHES TO THE GAS EXPLORATIONS IN THE SOUTH BASIN OF THE SOUTH YELLOW SEA BASIN

The south basin of the South Yellow Sea basin is an extension of lower Yangtze platform to the northeast.The south basin is very similar to the Subei basin in regional structure and geological characteristics of oil and gas.Successful exploitation of Zhujiadun gas field in Subei basin provides experience for explorations in the south basin.The authors compared reservoir conditions of south basin with the Zhujiadun gas field based on analysis of reservoir characteristics in Zhujiadun gas field and found they were very alike.The authors concluded that south basin of the South Yellow Sea basin possesses good exploration prospect,the gas fields have ancient generation and young accumulation,and the target is the belt of deep depression on the side of large fault.
