测井储层流体识别方法及其在低渗透油藏描述中的应用

Log reservoir fluid identification method and its application to low permeability reservoir description

针对大庆外围西部地区储层流体识别难度大的实际,研究了各套含油层系储层地质特征及测井响应特点,建立了油水层识别模型.该模型在新站、新肇、葡西等油田应用,测井解释符合率达87.7%.

In view of the fact that the reservoir fluid in the western periphery of Daqing oilfield is difficult to recognize, we have studied the geological features and the logging response characteristics of the various oil-containing formations and established models for the oil and water layer recognition. The application of the models to Xinzhan, Xinzhao and Puxi oilfields proved that the well-logging interpretation accuracy rate is 87.7%..
