南通地区地处长江三角洲前缘，水质优良的深层地下水是本区经济发展的重要支柱。根据该区的地质情况及地层岩性的物性特征，通过合理选择自然伽马、视电阻率及自然电位等物探测井参数来确定地层中含水层的赋存情况，并确定咸淡水层界面。%Nantong is located in the Yangtze River delta, where deep groundwater is an important pillar of economic development. According to the geological conditions and the characteristics of the stratigraphic lithology, the occurrence of water-bearing strata in the formation can be determined based on natural gamma radiation, apparent resistivity and natural potential.
