In-situ micro-area fluid tracing method and device, storage medium and computer equipment

The invention provides an in-situ microcell fluid tracing method and device, a storage medium and computer equipment. The method comprises the following steps: acquiring the types of elements contained in filling minerals in a target reservoir and the content of each element; pre-judging at least one mineral type contained in the filling mineral according to the element types and the content of each element in combination with the morphological characteristics of the filling mineral; and performing internal structure component phase analysis on each type of filling mineral, and determining the diagenesis evolution process of the type of filling mineral according to an analysis result. By means of the method, the diagenesis evolution process of the filling minerals in the reservoir can be accurately determined. 本发明提供一种原位微区流体示踪方法、装置、存储介质和计算机设备。该方法包括以下步骤：获取目标储层中的充填矿物所包含的元素种类及每种元素的含量；根据所述元素种类及每种元素的含量，结合所述充填矿物的形貌特征，预判所述充填矿物所包含的至少一种矿物类型；对每种类型的充填矿物进行内部结构成分相分析，根据分析结果确定该种类型充填矿物的成岩演化过程。通过本发明的方法能够准确确定储层中充填矿物的成岩演化过程。
