吉林油田某区测井精细解释模型的建立及应用

针对吉林油田×区油水分布复杂、油水识别难度大、测井解释符合率偏低的特点开展了测井精细解释研究。建立了分层位的孔隙度、渗透率高精度解释模型 ,其模型的相关系数较高 ,相对误差较小 ;建立了分层位的深侧向与声波时差以及与密度、深感应与声波时差以及与密度的交会识别图版 ,给出判别油水层的电性标准 ,4种饱和度模型结合使用可以比较准确地识别油水层。将所建立的模型应用到CLASS处理程序中。实际应用对一些老探井进行重新处理 ,处理结果证实其解释方法适合实际地质情况

Fine Log Interpretation Model of an Area in Jilin Oilfield and Its Application

This paper shows how a fine logging interpretation research was done according to the complex oil and water distribution, difficult oil and water layers identification and poor logging interpretation fitting rates. It also presents an interpretation model with high-resolution parameters and a resistivity property standard for oil and water layers. The model is used into CLASS processing program to process oil exploration well data and is verified that it is adaptable to the actual geological case very well. The paper has also provided evidence for oil and gas reservoir evaluation, reserve calculation and production design.
