我队在近几年的磷矿普查、勘探施工中,由于推广使用了钻进新工艺与新技术,使磷矿钻进效率与取心质量明显提高。过去因取心工艺落后,泥浆类型单一,漏失地层堵漏问题尚未解决,在钻进结构破碎、酥散、软硬夹层、粉状等磷矿层时,钻进效率低,取心质量难以达到地质要求,有的矿层需要偏斜补心,
In recent years, our team in phosphate rock census, exploration and construction, due to the promotion of the use of drilling new technology and new technologies, phosphate rock drilling efficiency and coring quality improved significantly. In the past, due to the lack of core technology, a single type of mud, lost formation plugging problem remains unresolved. When drilling structures such as crushed, crisp, hard and soft mezzanine, powder and other phosphate layers, the drilling efficiency is low and the coring quality is hard to achieve Geological requirements, and some strata need to offset the heart,
