为充分利用现有设备,改造提高上万眼需要更新筒井和新打筒井的质量,同时也为了增加筒井深度和井下蓄水深度,使不完整井变成完整井,以利于解决枯水年和冬季筒井供水不足的问题,解决施工的机械化问题。我们利用现有 SPJ—300型水井钻机,组装了拖车深筒井钻机(简称拖钻),经过八二、八三两年在西苏旗试验生产,效果良好,到目前为止已打筒井19眼,总进尺62.852米。下水泥管344.30米,成井13眼干孔6眼。按施工期直接费用为70元/米,加上管理费
In order to make full use of the existing equipment, it is necessary to upgrade the quality of thousands of wells needed to update the silos and new drums, as well as to increase the depth of the silos and the depth of underground water storage so as to make the incomplete wells into complete wells to help solve the dry years and The problem of insufficient water supply in winter tube wells solved the mechanization of construction. We have used the existing SPJ-300 water well drilling rig to assemble the towed deep-hole drilling rig (referred to as the tow drill). After eight years and 83 two years in the West Su Qi pilot production, we have achieved good results. So far, 19 wells have been drilled, The total footage of 62.852 meters. Under the cement pipe 344.30 meters, into wells 13 dry eye 6 eyes. According to the construction period direct costs of 70 yuan / m, plus management fees
