摘要
介绍了光电测距仪直接在井筒中测定井深导入高程和激光投点代替钢丝投点的试验研究 ,并和传统方法进行比较 ,结果令人十分满意。
The research of well depth direct measuring by electrophoto ranger and laser pointing instead of trans ferred heights by steel wire method are discussed. The new methods are compared with the traditional ones, and results are satisfied.
