| 摘 要： | 储集岩相是以基本标志反映储集岩的沉积相、成岩变化以及油气显示面貌的。采用的标志包括：岩石学标志(沉积相、镜质体反射率)，物性标志(三维孔喉比、配位数)以及有机地球化学标志(单有机包裹体光化学参数)。区分出的储集岩相类型不仅根据上述定量标志能进行自身评价，还可以编入相柱状图和古地理图进行预测和追索油气藏。依据由岩心或者岩屑制成双面抛光不加盖片的薄光片(岩心部分副样要浸注玫瑰红荧光剂并制成平行与垂直层理的三维薄光片)，用显微镜光度法、显微付里叶红外谱和激光拉曼谱确定以上标志。

| Abstract: | The reservoir rock facies, with its principal indicators, has recorded aspects of sedimentary facies, diagenetic change and oil gas indication. These indicators include ① petrological characteristics such as sedimentary facies and vitrinite reflectance; ② physical characteristics such as the pore/pore throat diameter ratio and the coordination number of pore throat connecting pore; and ③ organic geochemical parameters such as those photochemical parameters of individual organic inclusions. Based on these quantitative indicators, the defined reservoir rock facies not only can be used for evaluation of itself, but also can be put into facies columns or palaeogeographic maps to be used to predict and trace oil gas reservoirs. All these parameters can be determined with Microscopic photometry, micro FTIR and Laser Raman methods. The uncovered polished thin sections are commonly used for these analyses. For the convenience of studying pore throat structures, some duplicate core samples need to be soaked in the rose colour fluorescence liquid and then cut into three dimentional thin sections which are parallel and perpendicular to beddings. |
