我队自1982年开展砂钻工作以来，6年间累计完成砂钻有效工作量14543.34m，仅1987年就完成5068.20m，为1982年的9.61倍，效率提高2.7倍。但是，长期以来，砂矿钻探劳动强度大、管材损耗严重、搬迁工作繁重的问题，一直未得到圆满解决，影响了砂矿钻探的更大发展和经济效益的提高。为解决这些问题，经队行家们一致研究讨论指出：要是能避 Since our team commenced drilling sand drilling in 1982, the effective work volume of sand drilling completed in 6 years was 14,543.34m, which was 5068.20m in 1987, 9.61 times that in 1982, and the efficiency increased by 2.7 times. However, for a long time, the problem of heavy labor in sand drilling, serious pipeline loss and heavy relocation work has not been satisfactorily solved, which has affected the greater development of sand drilling and the improvement of economic benefits. To solve these problems, the team members unanimously study and discuss pointed out: if we can avoid
