摘　　要：针对龙岗地区沙溪庙组和凉高山组致密油层的特征,建立了储层品质的测井表征方法,形成了有效的致密油测井评价技术。结果表明:衍生反映岩性纯度的特征参数TPI,结合反映物性的AC曲线和含油性的Rt曲线,构建识别致密油层的产油指数法,较以往常用的图版法在识别致密油层方面效果更明显。According to characteristics of two tight reservoirs of both Shaximiao Formation and Lianggaoshan Formation in Longgang area,we developed a method for well- logging characterization of reservoir quality,and formed some effective well- logging evaluation technologies for tight oil. Results show that( 1) derivation can reflect TPI,a characteristic parameter of lithologic purity;( 2) combining with AC curves reflecting physical properties and Rtcurves reflecting oil- bearing property,the method of oil- producing index can be constructed to recognize tight oil reservoir. The index method is more obvious to recognize tight oil reservoir than the commonly- used plot method in the past.
