在毛主席革命路线指引下,在深入开展工业学大庆运动的推动下,我队于一九七五年四月开展人造金刚石钻进试验.一九七六年钻成14个钻孔,累计5283.15米,平均孔深377米.最高月进尺672.58米,纯钻时间最高达51.9%.各项主要技术指标如表1、2. Guided by Chairman Mao’s revolutionary line and driven by the Daqing Industrialization Movement, our team conducted a synthetic diamond drilling test in April 1975. In 1976, we drilled 14 drilling holes totaling 5283.15 The average hole depth is 377 meters, the maximum monthly footage is 672.58 meters, and the maximum drilling time is up to 51.9%. The major technical indexes are shown in Table 1 and Table 2.
