Abstract
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.
