摘要
The large oil-gas oilfield,discovered in the Tarim Basin of Xinjiang,has more than 0.1 billion tons OOIP.The ancient caves’ logging response characteristic with different filling degree and filler in the conventional well logs,electric array acoustic imaging,array sonic image and cross-plot analysis to identify the character of the cave filling are analyzing in conjunction with identifier such as drilling,logging,well testing and seismic in the paper.It is concluded that the cave reservoirs can be divided into completely filled,half filled and unfilled types according to the analysis.
