Formation fluid discrimination method, computer equipment and readable storage medium

The invention provides a formation fluid distinguishing method, computer equipment and a readable storage medium. The method comprises the following steps: performing equal-interval processing and data extraction on logging data of a target interval of a tested oil well in a target area to obtain a plurality of groups of time period data; each group of time period data is processed, the increasing rate of the temperature along with the time is obtained, and the processing comprises time standardization processing and cumulative time item adding; setting a unified cumulative time-temperature starting point; carrying out correlation analysis on accumulated time and temperature; integrating a plurality of groups of increasing rates, and establishing a discrimination standard in combination with oil testing data. The computer equipment comprises at least one processor and a memory in which program instructions are stored, wherein the program instructions are used for executing the instructions of the method.
