AI Technical Summary

Technical Problem

The development of karst reservoirs is affected by the complexity of karst distribution patterns and multiple phases of tectonic activity, and existing technologies make it difficult to accurately determine the migration path of karst fluids.

Method used

By classifying reference minerals in the test area and detecting trace element content, the changes in trace element content in the initial mixing zone and fluid migration zone are determined using cathodic luminescence testing and in-situ laser ablation plasma mass spectrometry. Combined with the trace element distribution coefficient, the migration direction and path of karst fluid are determined.

Benefits of technology

It improves the accuracy of determining the migration path of karst fluids, reduces complexity, and enhances the development effect of karst reservoir oil reservoirs.

Abstract

The present disclosure relates to the technical field of geology, and particularly relates to a karst fluid migration path determination method, device, equipment, medium and program. The method comprises the following steps: classifying a plurality of reference minerals in a to-be-measured region to obtain a plurality of first minerals and a plurality of second minerals, at least part of the first minerals are located in an initial mixing area, and each second mineral is located in a fluid migration area; detecting the content of a plurality of trace elements in each reference mineral; determining the initial mixing area and the migration direction of the karst fluid in the fluid migration area according to the content of each trace element in each first mineral and the content of each trace element in each second mineral, the karst fluid flows through the minerals at a historical time to form the reference minerals; and determining the migration path of the karst fluid according to the initial mixing area and the migration direction. The migration path of the karst fluid can be determined according to the plurality of reference minerals in the to-be-measured region, the karst distribution rule can be obtained, and thus the development effect of the karst reservoir is improved.
