潍坊市南部缺水地区找水定井综合物探方法研究

Study on comprehensive geophysical prospecting method for water exploration and well fixing in water shortage area in the south of Weifang

本文主要依据含水介质的性质,同时参考其他相关因素,将研究区地下水赋存环境划分为沉积孔隙型、风化裂隙型、构造裂隙型、岩溶裂隙型和层间裂隙型共5种类型;针对不同的地下水赋存类型,选择不同的物探方法组合,得到了不同的勘查技术流程,提高了找水定井的准确性和工作效率,更好地保障农村粮食生产安全和城镇饮水安全。今后山区找水的难度将会愈来愈大,在一些找水难度大的地区,必须采用更全面的综合物探方法,采集多种地质-地球物理信息,结合实际场地特征,进行综合比对分析,提取分析不同信息之间的相关性,进一步提高该技术的成功率和适用性。

Based on the properties of water bearing media and other relevant factors,the groundwater storage environment in the study area is divided into five types:sedimentary pore type,weathering fracture type,structural fracture type,karst fracture type and interlayer fracture type.According to different groundwater occurrence types,different combinations of geophysical exploration methods are selected to obtain different exploration technical processes,improve the accuracy and work efficiency of water prospecting and well location,and better ensure the safety of rural food production and urban drinking water safety.In the future,it will be more and more difficult to find water in mountainous areas.In some areas with great difficulty in finding water,we must adopt more comprehensive comprehensive geophysical exploration methods,collect a variety of geological geophysical informa-tion,conduct comprehensive comparison and analysis in combination with the actual site characteristics,extract and analyze the correlation between different information,and further improve the success rate and applicability of this technology.
