液动螺杆钻及其钻井方法是六十年代中期发展起来的一种新钻具和新技术。一九五五年美国史密斯国际公司的子公司史密斯工具公司根据单螺杆泵原理开始研究螺杆钻,经过九年取得成功,定名为“戴纳钻”。1964年小批量生产(生产一种规格的钻具六台),同时成立“戴纳钻井公司”,专门从事研究和生产戴纳钻、有关附属工具及钻井工艺。至今产品已系列化,并生产了各种规格的戴纳钻一千余台,目前有400~500台在西欧、中近东、东南亚、印尼、澳大利亚、加拿大、美国、墨西哥和拉丁美州等地应用,累计钻井超过300万米,最大钻井深度6900米。
Hydraulic screwdriver and its drilling method is a new drilling tool and new technology developed in the mid-1960s. In 1955, Smith & Sons, a subsidiary of Smith & Sons USA, started to research screw drills according to the principle of single screw pump. After nine years of success, it was named “Dana Drill.” Small-batch production in 1964 (production of a set of six drill rigs), and the establishment of “Dana Drilling Company”, specializing in the research and production of Dana drill, the related tools and drilling technology. Up till now, the products have been serialized, and more than 1,000 sets of Dana drill have been produced. At present, there are 400 ~ 500 units in Western Europe, Middle Near East, Southeast Asia, Indonesia, Australia, Canada, USA, Mexico and Latin America Application, total drilling more than 3 million meters, the maximum drilling depth of 6900 meters.
