美国Grey Wolf公司成功开发了一种新型钻井系统。它是为由独立垫块钻井井场钻多井眼而专门设计制造的。因垫块钻井可在一个较大的地区打多口井,可避开湖泊、城市、原始森林和野生动物保护区,所以它对周围环境的影响最小。与定向钻井技术相结合,该种新型多井眼垫块钻井系统可减 United States Grey Wolf successfully developed a new drilling system. It is specifically designed for drilling multiple boreholes from independent pad drilling well sites. Because pad drilling allows multiple wells to be drilled in a larger area, avoiding lakes, cities, primeval forests and wildlife reserves, it has the least impact on the surrounding environment. Combined with directional drilling technology, this new multihole well block drilling system can be reduced
