弱含水地层青山组火山岩地下水分布规律及解决缺水问题探讨

DISCUSSION ON THE LAW OF GROUNDWATER DISTRIBUTION AND RESOLVING THE PROBLEM OF WATER LACK IN THE REGION OF THE VOLCANIC STRATA OF QINGSHAN FORMATION

白垩系青山组火山岩是弱含水岩层,但在有利的岩性与构造的作用下,可以形成相对富水地段,通过物探固定小MN装置测深法与地质分析相结合,已打出一批好机井,从而解决了该区严重缺水问题。

The volcanic strata of the Cretaceous Qingshan Formation is a kind of weak groundwater aquifer,but it can also form some sections in which the groundwater is relative abundant under favourahle lithological and structural conditions.By combining geophysical depth sounding using the fixed miniature MN installation with general geological analysis,a number of pumped wells with good water pumpage have been drilled, thus the problem of great lack of water in the region has been resolved to a certain de-
