摘要
摘要:楚雄盆地由于其复杂的地质构造，基底深度及内部构造隆拗深度一直不明了.本文以楚雄盆地区域重力及航磁数据为基础，依据横贯东西的两条重磁电震剖面定量反演解释结果，并以云参1及楚参1钻井作为约束，分西区、中区及东区三个区块反演得到了楚雄盆地三叠系顶底界面深度，进而得到三叠系厚度分布特征.本次取得的成果为研究楚雄地区深部地质构造和主要沉积盆地厚度以及盆地基底深度提供了较为可靠的资料，可作为楚雄盆地油气评价的重要依据；同时也为复杂盆地地球物理-地质结构模型的构建提供了一条可行的思路.

Abstract:Because of complex geological structure, the depth of the basement and the internal structure of the Chuxiong basin remain unclear. In this work, we use the regional gravity and aeromagnetic data to make interface inversion in three blocks with constraints of integrated geophysical sections and geological interpretations of two gravity-magnetic-MT-seismic profiles. In this process, we also use drilling data(Yuncan 1 and Chucan 1) as constraints. Lasting this way we obtain the depth of Triassic top and bottom interface, and the thickness distribution of Triassic strata in this basin. These results provide detailed inversion data for study of the geological framework of the Chuxiong basin and a strong basis for breakthrough in the oil and gas evaluation in the basin. It also suggests a method for the construction of geophysical-geological structure models in complex basins.
