综合利用大地电磁、重力、磁力物探资料，以地质理论为指导，将油气模型的大地电磁（MT）正反演计算作为地质-重磁电物探综合解释的关键环节，以古生界有利储层为主要研究对象，开展雪峰山盆-山过渡带综合物探解释工作和研究。结果表明雪峰山盆-山过渡带内下古生界作为区域性有利储层，早期背斜因受后期构造改造破坏严重，断裂较发育，导致油气逸散；而向斜构造内古生界保存完整，有利于油气运移、储集和保存。雪峰山盆-山过渡带内油气勘探应以构造改造较弱的宽缓向斜为主，以下寒武统碳酸盐岩为主要储层的海相油气成藏组合具有一定的油气勘探开发潜力。

Using the magnetotelluric (MT ),gravity and magnetic data and the geological theory, taking the magnetotelluric sounding forward and invert computation as the key link of integrated interpretation,and taking the Paleozoic favorable reservoirs as the main object of study,the authors carry out the integrated geophysical interpretations and surveys of the basin-range transition belt in Xuefengshan.The study results show that the lower Paleozoic sediments form the regional favorable reservoir of the Xuefengshan basin-range transition belt,but the anticline is destroyed deeply by the tectonic deformation and its faults develop,leading oil and gas to escape easily and vertically,and the Paleozoic strata in the syncline are perfectly preserved and favorable to the migration,storage and conservation of oil and gas.The direction of the oil and gas exploration in the Xuefengshan basin-range transition belt should focus on the wide-slow synclines subj ected by relatively weak tectonic deformation,and the marine hydrocarbon accumulation combination taking the carbonate rock of the Lower Cambrian as the main reservoir has a certain exploration and development potential of oil and gas .
