目前西部沙漠区块施工中,沙驼钻机的泥浆钻井是重要的施工手段,特别是井深超过30m以后,泥浆钻井施工能力强、效率高的优势非常明显。但同时,泥浆钻井需要大量的水源,沙漠地区干旱缺水,钻机钻井取水困难一直是沙漠地区施工生产的一大困扰。近几年施工的皮山、豫北、董二井等项目都遭遇了同一问题,极大地影响了钻井效率。通过尝试使用MAN钻机进行深井取水作业并取得成功,找到了解决这一问题的办法,极大地提高了我们的生产实效、降低了项目成本。
At present, in western desert block construction, mud drilling of Shala drilling rig is an important construction method. Especially when the depth is more than 30m, the advantage of strong drilling mud construction and high efficiency is very obvious. But at the same time, mud drilling requires a large amount of water resources. Drought and water shortage in desert areas and drilling rig drilling water intake difficulties have always been a major disturbance in the construction of desert areas. In recent years, the construction of Pishan, North Henan, Dong Erjing and other projects have encountered the same problem, which has greatly affected the drilling efficiency. By trying out and succeeding with the deep drilling operation of MAN rigs, we have found a solution to this problem, which has greatly enhanced our production efficiency and reduced the project cost.
