高效、低成本一份英格索兰公司报告说:“在美国,要钻穿钻井上部井段的坚硬而复杂岩层时,如果采用潜孔锤钻进,能节省大量的时间和费用。”舍菲尔德国际石油服务公司,在钻进上部井段时,地层条件相同,他们作过一定对比,采用潜孔锤(英格索兰公司的DHD-112型)钻进,比用传统的三牙轮钻头和冲击回转钻具钻进,可节省三分之二的工时。他们曾在宾夕尼亚西南部地区钻凿了30口钻井,钻孔的孔径为15英寸,上部井段(对比试验用)设计深度为236英尺,每一钻井旁另外
High Efficiency and Low Cost Ingersoll Rand Company reports: “In the United States drilling and piercing through a hard and complex rock formation in the upper wellbore can save a lot of time and money.” "Sheffield International Petroleum Services, drilling in the upper section, the same stratigraphic conditions, they made a certain comparison, the use of down-hole hammer (Ingersoll Rand’s DHD-112 type) drilling, with the traditional three Tricone bits and percussion rotary drilling tools can save two-thirds of man-hours. They drilled 30 wells in the southwestern part of Pennsylvania with holes 15 inches in diameter and a design depth of 236 feet in the upper section (for comparison tests)
