我场自一九五九年至一九六四年先后在场内钻了13眼自流井,进行深层取水试验。这些井孔所采用的管种各不相同,计有木管5眼,无缝钢管4眼,铸鉄管1眼,石棉水泥管3眼。 石棉水泥管一般用作为输水管,还未有人用作深层取水的井壁管,更不用说用于深层自流井的井管。为了节约钢材,降低凿井造价,加速开发利用地下水,厅领导指示厅钻探队在我场进行了以石棉水泥管代替钢管引取深层承压水的试验。
Our field has successively drilled 13 artesian wells in the field from 1959 to 1964 for deep water withdrawal tests. These wells are used in different pipe types, including 5 wood tube, 4 seamless steel tubes, casting tube 1, 3 asbestos cement pipe. Asbestos cement pipes are generally used as water pipes and have not been used as well wall tubes for deep water withdrawal, let alone for well tubes used in deep, artesian wells. In order to save the steel, reduce the cost of shaft sinking and speed up the development and utilization of groundwater, the Drilling Team of the Office of Lead Instruction of Office conducted a test in our field to introduce deep confined water with asbestos cement pipe instead of steel pipe.
