摘要
缩短钻井周期是降低深井钻井成本和钻井风险的关键,这需要钻井新技术、新工艺、新材料、新工具的研究与应用,这必然要很大程度上依赖于大量的室内试验。斯伦贝谢Terra Tek钻完井实验室有全球最先进的全尺寸钻井模拟试验装置,在30多年间做了大量的模拟试验,试验结果对钻井技术发展、钻头设计、钻井液体系优选及性能优化起到了积极的促进作用。在介绍Terra Tek全尺寸钻井模拟试验装置的组成及主要功能的基础上,分析了该实验室在美国岩石力学协会钻井论坛、冲击钻井及深井钻井模拟试验中取得的主要成果,并介绍了该实验室在页岩气地层特点、开发技术和井眼稳定等方面取得的研究进展。
Deep-well drilling is essential for oil and gas recovery,and in many ways drives the advancement in energy recovery for unconventional and difficult reservoirs. Furthermore, as the world moves more toward unconventional oil and to gas,more and more reliance is placed on drilling. This is particularly true for gas ,as more length of drilled hole-much greater lengths of drilled hole-will be required for the same amount of BTU＇s recovered. Drilling is often the key to economic success and risk reduction. Advancements are being made in drill bits,in drilling muds,and drilling techniques. Unfortunately we cannot ＂see＂ the drilling operation at great depths, and must rely on experimentation trial-and-error to a large extent. The field drilling is to some extent a ＂free＂ laboratory, and indeed advancements are being made via this field laboratory and trial-an-error experimentation. Unfortunately, there are limitations with this approach, and the introduction of new innovations tends to be slow and limited. However, the Schlumberger TerraTek Drilling and Completions Laboratory offers an opportunity for quantitative measurements that greatly add to the field laboratory observations. The TerraTek Drilling and Completions Laboratory is the most advanced facility in the world for full-scale drilling experimentation, simulating great depths. The TerraTek facility has been operated for nearly three decades and is well recognized for its contributions to drilling advancements. This paper reviews this world recognized facility, and notes some important observations.
