摘要： Cuttings are removed from air drilling fluid used in an air drilling system by delivering the cuttings and air drilling fluid into an air-tight enclosure (22), decreasing the flow rate of the air through the enclosure (22) to allow the cuttings to settle and separate from the airflow and be contained within the enclosure (22). The air, substantially devoid of the cuttings, is discharged. The enclosure (22) is positioned at an angle to facilitate the discharge of the contained cuttings. Preferably, the enclosure (22) is of a size which will allow it to be transported on public highways without special movement permits, and the exhilarating equipment used may be contained within the enclosure (22) during transportation.
