在钻探施工中,对付复杂地层的办法,一是采用泥浆钻进,二是下套管.近几年603队开动钻机最多达15台,每年完成钻探任务3～3.3万米.每年泥浆费用(据不完全统计)就达8万多元,还丢弃数百米套管,并且往往因泥浆供不上和起拔套管耽误生产时间.针对这种情况,1974年公司在603队组成复杂地层防坍堵漏小组,进行了水泥和氰凝灌浆试验.由于氰凝成本高,货源不足,重点 In the drilling construction, the way to deal with complex formations is to use mud drilling, and the second is the casing.In recent years, 603 teams start up to 15 rigs, drilling tasks completed each year 3 to 33000 meters annual mud costs According to incomplete statistics) reached more than 80,000 yuan, but also discarded hundreds of meters casing, and often because of the mud can not afford to pull up the casing and delay the production time.In response to this situation, in 1974 the company composed of complex formation 603 Anti-slump plugging team conducted a cement and cyanidation grouting test due to the high cost of cyanidation, lack of supply, the focus
