摘　　要：以常规测井和储层参数岩心实测资料为基础,建立了储层物性参数单参数拟合模型和多元回归线性解释模型,基于岩电分析测试资料建立了阿尔奇含水饱和度解释模型,利用非线性BP网络法,构建了须家河组主力储层各参数精细解释模型.对多种储层参数解释模型进行优选.结果表明非线性的神经网络解释模型与实际测试资料吻合性最高,能对该地区复杂的致密储层参数进行准确解释.This paper takes the conventional logging data and the core test results of reservoir parameter as a foundation,establishes the corresponding reservoir natural parameter single parameter fitting model and the multi-dimensional return linearity explanation model.The Archy water saturation explanation models are set up based on the lithology electricity analysis data.Finally it selects the non-linear BP network method to construct the reservoir parameters fine explanation models of the brunt reservoir in Xujiahe Formation.This study,via a variety of reservoir parameter interpretation model for optimization,finds the nonlinear neural network model fits the actual test data well.This research can make a fine explanation for the reservoir parameter of the tight reservoir in this area.
