根据21眼地质勘探孔、水文地质勘探孔及28个地面核磁共振(SNMR)勘探点资料,对比分析了钻孔揭露的含水层厚度与SNMR解译的含水层厚度、钻孔抽水试验所得含水层导水系数与SNMR解译的导水系数的差异,据此绘制出西辽河冲淤积平原潜水含水层厚度与导水系数分布图。结果表明,在SNMR试验噪音较小时SNMR解译的含水层厚度、导水系数与钻孔揭露的含水层厚度及水文地质试验结果吻合较好。利用SNMR技术解译含水层厚度、导水系数并通过少量钻孔及抽水试验予以校正,不仅可以节省大量勘探工作量,而且精度及可行度也较高。
According to the data of 21 geological exploration holes, hydrogeological exploration holes and 28 ground-based nuclear magnetic resonance (SNMR) exploration points, the thickness of aquifer exposed by SND and the thickness of aquifer exposed by SNMR are comparatively analyzed. The aquifer According to the difference between the water conductivity coefficient and the water conductivity coefficient interpreted by SNMR, the distribution of the aquifer thickness and water conductivity of the scour silting plain in the Xiliaohe River was plotted. The results show that SNMR interpretation of aquifer thickness, water conductivity coincides well with the thickness of the exposed aquifer and the hydrogeological test when the SNMR test noise is small. Using SNMR technology to interpret aquifer thickness and water conductivity and calibrating it with a few drilling and pumping tests not only saves a lot of exploration workload, but also has higher accuracy and feasibility.
