摘要
在超深地热井施工中,深部的煤系地层是事故的多发层段。利用高压喷射快速钻井技术和适合的聚合物泥浆体系,顺利的钻过埋深超过2 000多m和3 000多m的煤系地层,防止了事故的发生,提高了钻进效率。
During the ultra deep geothermal drilling operation,the deep part of coal measures strata is the sector of accident frequently happened.To use the high pressure jetting fast speed drilling and suitable polymer drilling fluid can smoothly drill through more than 3000m coal measures strata under 2000m depth.The technology can prevent accident and increase drilling efficiency.
