在毛主席革命路线的指引下,坚持“独立自主,自力更生”的伟大方针,胜利油田为了加快勘探开发速度,油田党委提出一个钻头打一口2300～2500米中深井的指示,从1972年底开始组织金刚石刮刀钻头攻关,在各级党委的正确领导下,在兄弟单位大力协作下,经过两年来的反复试验,大颗粒聚晶人造金刚石刮刀钻头试验初见成效。1974年三季度以来,先后在3252钻井队,×123井和××12—24井,试验了两只金刚石刮刀钻头,第一只钻头从井深59米打到井深2319.64米,进尺2260.64米,机械钻速42.77米/小 Under the guidance of Chairman Mao’s revolutionary line, adhering to the great principle of “independence and self-reliance”, Shengli Oilfield Party put forward a drill bit to instruct medium and deep wells of 2,300 to 2,500 meters in order to speed up exploration and development. From the end of 1972, the organization of diamond scrapers Under the correct leadership of the party committees at all levels and with the concerted efforts of their brother units, after two years of trial and error, large-particle polycrystalline man-made diamond blade trials have achieved initial success. Since the third quarter of 1974, two diamond blade drills have been tested in 3252 drilling crew, × 123 well and ×× 12-24 well. The first drill drilled 2319.64 meters from the well depth to well depth of 2260.64 meters and the machinery ROP 42.77 m / small
