四川盆地分布着面积达157000平方公里的白垩系和侏罗系的紫红色砂岩、泥岩,这通称为红层。我们十余年来在重庆、沪州、内江、简阳、成都和金堂等地红层分布区,为解决工农业用水而进行供水水文地质勘察和凿井实践,先后共完成35项工程,钻凿了112口井孔,总钻探进尺为6632.97米,找到的总水量为18338米~3/日。单井出水量最大的为1114.6米~3/日,但也有的是干孔。
The Sichuan Basin has 157,000 square kilometers of Cretaceous and Jurassic fuchsia sandstone and mudstone, commonly known as red beds. For more than ten years in Chongqing, Huzhou, Neijiang, Jianyang, Chengdu and Jintang red distribution areas, in order to solve industrial and agricultural water supply hydrogeological exploration and drilling practice, has completed a total of 35 projects, drilling A total of 112 wells were drilled. The total drilling footage was 6632.97 meters and the total volume of water found was 18338-3 / day. The largest single-well water output is 1114.6 m ~ 3 / day, but some dry holes.
