摘要
空气钻井在提高机械钻速、缩短钻井周期、降低钻井成本、发现保护气田和提高产能有着重大贡献。但在井斜控制方面的研究还很欠缺。文中介绍了目前空气钻井在井斜控制上的一些措施,尤其重点阐述了空气锤和空气螺杆钻井技术。空气锤技术在四川地区现场试验中,取得了显著效果,防斜成功率在95%以上,是目前最有效最可行的防斜打快技术。空气螺杆技术较空气锤技术不成熟,效果不明显,还要不断研究和摸索。
Air drilling has many merits, such as improving drilling rate, shortening drilling cycle, reducing drilling cost, protecting gas field and enhancing productivity etc. But the research on borehole deviation control is very few. Air Drilling Co. of Sichuan Drilling & Production Technology Research Institute has carried out lots of research and test to borehole deviation control technique of air drilling, an effective borehole deviation control technique was formed. The paper analyzed the reasons of hole deviation, presented the field application of borehole inclination control technique and applied effect.
