本次勘查区位于潮水盆地北缘东段,属戈壁、干旱半沙漠地貌,为了更好的查明区内的煤系地层赋存情况及分布范围、地质构造情况、以及基底埋深深度及起伏形态等问题,进行了二维地震勘探与可控源音频大地电磁法( CSAMT法)相结合的综合勘探。两种方法综合分析、相互印证、相互参考,克服了单一物探方法的局限性,实现了优势互补,使解释结果更准确可靠。
本次勘查區位于潮水盆地北緣東段,屬戈壁、榦旱半沙漠地貌,為瞭更好的查明區內的煤繫地層賦存情況及分佈範圍、地質構造情況、以及基底埋深深度及起伏形態等問題,進行瞭二維地震勘探與可控源音頻大地電磁法( CSAMT法)相結閤的綜閤勘探。兩種方法綜閤分析、相互印證、相互參攷,剋服瞭單一物探方法的跼限性,實現瞭優勢互補,使解釋結果更準確可靠。

The exploration area is located in the eastern of northern Chaoshui basin.The comprehensive explorations of two-dimensional seismic exploration and controlled source audio magnetotelluric method ( CSAMT method) were used in the ex-ploration area.CSAMT method can solve the problems of overburden thickness, basement depth and substrate undulating morphology.2D seismic exploration can identify the occurrence of coal-bearing strata, burial depth, geological structures and undulating forms.The comprehensive exploration methods can overcome the limitations of a single exploration method and make the interpretation of exploration results more accurate and reliable.
