机井施工过程中,依国家供水规范的要求,应测量井孔和井管的垂直度。由于回转钻机的钻杆较粗,设备复杂直接测井斜有难度,使用测斜仪费用高,故多数施工队不测井斜,也不愿购买贵重的测斜仪。现提出自制木尺和钻杆测斜法,简单实用,便于机井工程监理和施工人员操作,效果良好。
During the construction of a well, the verticality of the borehole and the well pipe should be measured according to the requirements of the national water supply regulations. Due to the rough drill pipe drilling rig, complex equipment direct logging inclined difficult, the use of inclinometer cost is high, so most of the construction team not measured inclination, do not want to buy expensive inclinometer. It is proposed that self-made wooden ruler and drill-pipe inclinometer method is simple and practical, which is convenient for supervising of well engineering and construction personnel and has good effect.
