原生生物成因白云岩的识别方法
摘要：
本发明提供了一种原生生物成因白云岩的识别方法，所述原生生物成因白云岩的识别方法包括：在待测白云岩样品的表面镀一导电膜；对镀有导电膜的所述待测白云岩样品进行能谱面分析，获取所述待测白云岩样品的镁元素面分布图；根据所述镁元素面分布图判断所述待测白云岩样品是否为原生生物成因类型。利用本发明提供的识别方法，可以判断白云岩是否原生生物成因类型。利用本发明提供的方法可以快速、可靠地判断白云岩是否为原生生物成因类型，对寻找致密碳酸盐岩储层中相对优质的白云岩储层具有重要指导意义。
摘要（英）：

The invention provides a recognition method of primary biogenic dolomite. The recognition method of the primary biogenic dolomite comprises steps as follows: the surface of a to-be-tested dolomite sample is coated with a conductive film; the to-be-tested dolomite coated with the conductive film is subjected to energy spectrum surface analysis, and a surface distribution diagram of magnesium elements in the to-be-tested dolomite is obtained; whether the to-be-tested dolomite sample is in the primary biogenic type according to the surface distribution diagram of the magnesium elements is judged. With the adoption of the recognition method, whether the dolomite is in the primary biogenic type can be judged quickly and reliably, and the method plays an important instructive role in searching of relatively high-quality dolomite in a compact carbonate reservoir.
