复杂地层的护壁与堵漏，长期以来，一直是我局钻探工作的技术关键之一。它不仅影响钻探生产的效率，同时也影响钻探工程的质量。特别是小口径钻进，如何顺利通过复杂地层，充分发挥小口径金刚石钻进优质、高效的特点，更具有现实意义。1976年潜山会议以来，复杂地层钻探施工本着“因地制宜，综合治理，防治结合，讲求实效”的原 The protection of the walls and plugging of complex formations has long been one of the key technologies for the drilling work of our bureau. It not only affects the efficiency of drilling production, but also the quality of drilling engineering. In particular, small diameter drilling, how to successfully pass through complex formations, give full play to small diameter diamond drilling high quality and efficient features, more practical significance. Since the buried hill conference in 1976, the drilling of complicated strata has been carried out according to the principle of “according to local conditions, comprehensive management, combination of prevention and treatment, stressing practical results”
