RB50车载钻机是德国宝峨公司生产的全液压顶驱钻机,它具有扭矩大,可施工大口径水源井、瓦斯抽放井及煤层井的能力,同时具备绳索取心、空气潜孔锤和气举反循环钻井等功能。以该钻机的装备、性能及参数为基础,着重介绍了它在空气潜孔锤正循环钻井、泥浆常规钻井、两套空气压缩机并车的空气潜孔锤钻井和双壁管气举反循环钻井方面的施工工艺,并对各工艺中钻进参数及施工中的注意问题进行了必要的说明。提出了该钻机可在水平井施工和贯通式潜孔锤气举反循环钻井方面发展的思路。
RB50 car drilling rig is the full hydraulic top drive drilling rig produced by Germany Bao E Company. It has the ability of torque, large diameter water well, gas drainage well and coal seam well. At the same time, it has the advantages of rope coring, air DTH and gas lift Reverse circulation drilling and other functions. Based on the equipment, performance and parameters of the drilling rig, this paper focuses on its application in the air DTH positive circulation drilling, conventional mud drilling, two sets of air compressor and DTH drilling and double-wall gas lift countercurrent Drilling aspects of the construction process, and the process of drilling parameters and construction of the attention issues were the necessary instructions. The idea that this drilling rig can be developed in horizontal well construction and through-hole downhole hammer gas lift countercurrent drilling is proposed.
