孢粉颜色指数是油气勘探评价的一项重要指标,我室计划研制提供此项指标测定用的全套标祥。 确定生油岩成熟度和石油演化阶段是油气勘探中地质评价的重要任务之一。普查勘探中划分成岩阶段、确定生油岩有机质的变质程度和油、气生成与破坏的界限虽已有很多有机地球化学指标,但是孢粉的颜色指数却是其中最简单、实用和比较有效的,现已为各国石油公司普遍采用于评价生油岩的成熟度,只需有一台普通显微镜和一套孢粉色级标样就可建立这项指 Spore powder color index is an important indicator of oil and gas exploration and evaluation, I plan to develop room to provide this indicator for the determination of a full set of standard. Determining the maturity of the source rocks and the stage of petroleum evolution is one of the important tasks in the geological evaluation of oil and gas exploration. Although there are many organic geochemical indicators for the demarcation of diagenetic stage in census and exploration to determine the degree of organic matter deterioration and the generation and destruction of oil and gas in the source rocks, the color index of sporopollen is the simplest, practical and effective , Is now commonly used by oil companies in various countries to evaluate the maturity of oil-bearing rocks. An ordinary microscope and a set of sporopollen-grade standards can be used to establish this index
