摘要
Abstract
Using time-frequency electromagnetic data and logging data constraints to improve the resolution of electromag-netic inversion results,the deep electrical structure and oil and gas distribution areas of Bashkbulak Belt and Upoer Structural Zone in the southwest and western regions of Taxian were discussed.This area's topography,shallow surface morphology,and deep geological structure are relatively complex,and effective seismic data cannot be obtained,which seriously restricts the oil and gas exploration of the target layer.Time-frequency electromagnetic has the advantages of large exploration depth,high sig-nal-to-noise ratio,and is not subject to high-resistance shielding.The main faults and folds in this area were effectively identi-fied through the processing and interpretation of the time-frequency electromagnetic data of the Bashibulak-Upor region.The inverted resistivity profile and polarizability profile in the north-south and northwest directions show the electrical,structural characteristics of the southwest depression of the tower being extruded by the South Tianshan Mountain and Kunlun Mountain simultaneously.The two sides form a thrust pushover in the form of a hedge structure,covering the southwest depression of the tower,and the pusher on both sides develops multiple rows of thrust faults,which are distributed in a shingle pattern;the south side is the Wupoer tectonic belt,the north side is the Bashkbulak tectonic belt,and the basin shows obvious fault contact relationship,and the north and south sides are regional large faults.关键词
