南海西部海域复杂流体识别方法研究及应用

Research and application of complex fluid identification method in western South China Sea

在研究南海西部复杂流体性质测井、录井响应特征的基础上,优选识别流体性质的敏感参数,编制交会图版,定性识别复杂流体性质;根据敏感参数,形成多条曲线交会,分析层内流体的变化规律;同时通过气测参数计算气油比,定量识别复杂流体性质。

On the basis of studying the response characteristics of complex fluid properties logging and logging in the west South China Sea,this paper selects the sensitive parameters to identify the fluid properties,makes the intersection chart,and qualitatively identifies the complex fluid properties.According to the sensitive parameters,a number of curves are formed and intersected to analyze the changing law of the fluid in the layer.At the same time,the gas-oil ratio is calculated by gas measurement parameters,and the complex fluid properties are identified quantitatively.
