复杂地层金刚石绳钻提高效率的技术对策

Technical Measures of Raising Efficiency by Use of Diamont Line Drill in the Complex formations

从套管的使用及处理技术、重型绳索取心钻进技术的应用、优质无固相泥浆及排粉系统的改进、提高纯钻率及时效的几点作法等四个方面进行了讨论,得出了复杂地层用金刚石绳钻是能够提高效率的结论,提出了相应的技术对策。

This article discusses the use and treatment of casing, application of heavy rope coring and drilling technique, improvement of high—quality non—solid mud and dust—cleating system, and increase of net drilling efficiency and effectiveness. It is conluded that the use of diamond line drill can raise the efficiency. The associated technical measures are also put forward.
