摘要
意大利斯戈宝(Scorpio)干式水平定向钻机是全球首台无泥浆干式定向钻机,它的诞生改变了水平定向钻进工业的轨迹,是世界水平定向钻机的一个革命性的里程碑.
Most drilling systems use drilling mud / bentonite, but the financial and social costs can be high. Scorpio dry-rock directional drilling rigs use high powered compressed air with a biodegradable additive, leaving no fluid residue and costly clear-up / recycling operations. This results in a complete dry drilling process, unlike wet drilling systems.
