在深入开展工业学大庆的群众运动中，我队应用尿醛树酯进行钻孔堵漏，解决了钻探施工中坍塌漏水的问题。保证了钻探生产的正常进行。我队施工的部分矿区，由于地层复杂，钻孔坍塌漏水严重，长期以来，成为影响生产的一个关键问题。遵照毛主席关于“我们必须打破常规，尽量采用先进技术”的教导，在省局的大力支持和队党委的直接领导下，学习兄弟队的先进经验。从去年四月份开始试用尿醛树酯进行钻孔的护孔和堵漏。通过半年多的生产实践，在钻孔堵漏方面，取得了较好的效果，先后在两个矿区，六个钻孔十多个漏水孔段进行堵漏试验，绝大多数都获得了成功，保证了生产的顺利进行，到目前为止，只有一个孔段由于地层裂隙较大，漏水特别严 During the mass movement of Daqing in industrial science, our team used urea-formaldehyde resin to plug the holes and solve the problem of collapsing and leaking during drilling. Ensure the normal drilling production. Due to the complex strata and the serious water leakage caused by the collapse of drilling holes, some of the mines under construction by our team have become a key issue affecting production for a long time. Following Chairman Mao’s teaching on “We must break the routine and try to adopt advanced technologies”, we should learn from the advanced experience of Brotherhood under the direct support of the provincial bureau and the party committee of the party. Since April last year, urine urea formaldehyde test drilling holes and plugging. Through more than half a year of production practice, we achieved good results in drilling plugging. We conducted plugging tests successively in more than 10 water leakage holes in two mining areas and six drilling holes, most of which were successful. To ensure the smooth progress of production, so far, only one hole due to the formation of cracks larger, particularly leaking
