This study thoroughly inspects reciprocal method and leap-frog method of EDM trigonometric leveling along with relationship between EDM height, ellipsoid height, and orthometric height. An experimental area with 200m, 400m and 600m span intervals were set up with vertical angle error ±1.5〞and EDM error ±（2mm+2×10-6×Smm）.

本研究规划实验区实地针对200m、400m、600m三种测段长，采用之全测站仪之垂直角中误差为±1.5〞，测距中误差为±（2mm+2×10-6×Smm），进行EDM三角高程测量，并对测量方法及观测成果精度进行分析，实际探讨短距离EDM三角高程代替水准测量的可能性。

Due to high-quality requirements of scientific exploration well,long open-hole,long coring footage,and frequently changing lithology,the length of inner tube shoe was increased,the surface slippy degree between core catcher and inner tube sh...

针对科学探井对岩心质量要求高及该井裸眼井段长、取心进尺长、地层岩性变化频繁、取心施工难度较大等问题，采取加长刻刀座轴向长度，增加岩心爪与刻刀座表面光滑度，优选取心钻头，调整钻井液性能和选择配伍性好的钻头与刻刀座、合理的钻进参数等措施，保证了定向取心收获率，取心累计进尺103.66 m，收获率99.85%，为科学研究提供了可靠的岩心资料。
