位于湘中拗陷中部的邵阳凹陷是南方找油的重点地区之一。工区地表为低丘地形,出露下石炭系灰岩,潜水面较深,裂隙、溶洞发育,地表地震地质条件很差,但深部地震地质条件较好。进行地震攻关试验工作以来,初步获得了一些有意义的反射资料,为碳酸盐岩出露区地震工作提供了一些认识和分析的依据。 Shaoyang Sag, located in the central part of the Central Hunan Province, is one of the key areas for oil exploration in the south. The surface of the work area is a hilly terrain, exposed under the Carboniferous limestone, deep diving surface, fissures, karst cave development, surface geological conditions of the earthquake is poor, but deep geological conditions better. Since the earthquake research work, some meaningful reflection data have been obtained initially, which provides some basis for understanding and analyzing the seismic work in the outcrop area of ​​carbonate rocks.
