Element Logging Method for Complex Lithology Identification Based on Multi-Mineral Model:A Case Study of the Ordovician in Weiyuan Area
摘要
Abstract
The new drilling technique tends to produce finely fragmented or even powdered cuttings from downhole.Given the complex lithology of the Ordovician formation and the limitations of conventional cuttings identification methods,previous interpretations of the original lithological profiles in multiple wells in the Weiyuan area have been found to be inaccurate.To address this issue,we propose utilizing element logging data to establish an element-mineral conversion model and create element lithology identification charts for lithology identification in the study area,with verification through thin section analysis.Test results demonstrate that the element logging method based on a multi-mineral model achieves high accuracy in identifying complex lithology.This method has been successful-ly applied to correct the lithological profiles of 21 wells in the Weiyuan area,thereby providing a reliable litholog-ical basis for the subsequent redevelopment of existing wells.关键词
