我队广大职工，经过无产阶级文化大革命和深入批林批孔，大胆采用“盲管抽水”，经过两年来的生产实践，取得了良好成果，对深层水的勘探，可以保证抽水质量，节省大量管材，免除了起拔套管的困难，缩短了时间，是一种可取的方法。一、适用范围第四纪松散地层中的一般勘探孔、深部含水层的勘探孔、以及“探采结合”孔，均可适用盲管抽水（深部含水层虽然不须成井，但必须进行抽水试验）。 After a proletarian cultural revolution and thorough appraisal of bore holes, we bravely adopted “blind pipe pumping” and achieved good results after two years of production practice. The deep water exploration can ensure the quality of pumping and save a lot of Pipe, eliminating the difficulty of pulling the casing, shorten the time, is a desirable method. First, the scope of Quaternary unconsolidated strata in general exploration holes, deep aquifer exploration holes, and “exploration and mining combined with” holes, are applicable to blind pipe pumping (although deep aquifers do not need to make a well, but must be pumping test ).
