    摘要： A method of constructing a borehole (10) drilled with a drilling apparatus (16), the method comprises:
    connecting a flexible tubular liner sleeve around the outside of the drilling apparatus and connecting the sleeve (22) around an upper opening of the borehole so as to pass into the borehole; progressively extending the sleeve into the borehole as drilling progresses while maintaining connection to the drilling apparatus and borehole opening; at a predetermined point in the drilling, expanding the sleeve so as to contact the borehole wall; and setting the sleeve so as to be fixed to the borehole wall after expansion. Apparatus for use in such a method comprises: a flexible, expandable sleeve; a first connector for connecting the sleeve around the outside of a drilling assembly; and a second connector for connecting the sleeve around the opening of the borehole; wherein the sleeve is arranged to extend through the borehole between the connectors as drilling progresses.

    摘要： A method of stabilising an unconsolidated zone (18) of a borehole, including the steps of: forming a region of the borehole having enlarged diameter (22) in the unconsolidated zone when compared to the adjacent region above; positioning a fluid-filled casing (26) in the borehole extending across the unconsolidated zone and into the adjacent region above, the liner having a pipe (28) extending therethrough into a lower portion and being connected to a cement supply at the surface; pumping cement from the surface inside the pipe so as to exit the liner at the lower portion and flow upwards to fill the annulus (44) formed between the outside of the liner and the borehole in the unconsolidated zone and to extend into the adjacent region above; withdrawing the pipe (28) from the casing while pumping fluid therethrough so as to maintain the liner substantially fluid-filled and to displace cement above the liner in the adjacent region; and drilling through the cement and liner in the unconsolidated zone after the cement has set to form a borehole of substantially similar diameter to that of the adjacent region above.
