摘　　要：本次工作地区为重庆市武隆县周围,工作主要任务目标,利用重力和大地电磁测深MT,初步揭示武隆区块震旦系-下古生界等重点层系地层特征及构造样式,基本查明浅部构造与深部构造之间的关系,从构造角度分析武隆区块油气保存状况.我们在工区布置了2条测量剖面,位于武隆县南部,贵州道真县北部.两条剖面长度分别30km和50km,总长度为80km.主要的工作方法大地电磁测深MT和重力,其中MT点距为500m,重力点距为50m.经过野外数据采集、数据处理和分析等手段,对两条剖面进行了定性和定量解释并推断了3条断层、有利于油气保存条件的地层.In this paper, mainly discuss about effect of non-seismic geophysics method on Wulong area in Chongqing provence. The main task of work, to explain the strata characteristics and tectonic style of sinian system-lower palaeozoic layer and find out between surface and deep structure of earth to analysis oil and gas preservation. We finished two section of survey profile ,one is 30kin length and another 50km length. The main methods of work the magnetotelluric sounding MT , distance between each point is 500 meter, gravity method and distance between each point is 50m. After field data acquisition, data processing and analysis, and other means, to two profiles are the qualitative and quantitative interpretation and concluded that the article three fault, and potential layer to preserve oil and gas.
