摘要： The present invention discloses a cutting tool integrated in a drillstring for enlarging a borehole, where the cutting tool at least comprises: one or more side mills (12, 13, 14) arranged along the axis of said drillstring in a reamer housing (11), where the side mills (12, 13,14) are adapted to be rotated relative to the tool housing (11) by individual driving means. The self driven rotational side mills may be dome shaped cones where expand radially out of the reamer housing (11), or may be a special non-circular dome shaped cones where rotates without expanding.

摘要： The present invention concerns an apparatus for modifying sidewalls of a borehole. The apparatus includes a longitudinal housing adapted to fit inside the borehole. The housing includes a first end portion, a second end portion, and a side portion between said end portions, adapted to face the sidewalls of the borehole. Means are provides on the side of the housing for removing material from said borehole sidewall. The housing is adapted to be rotated with a controlled rotational speed in relation to said borehole sidewalls and to be fed in a controlled rate of longitudinal motion in relation to said borehole. Furthermore, the invention relates to a method for making a borehole with internal, helical grooves.

摘要： The present invention concerns an apparatus (1) for modifying sidewalls of a borehole. The apparatus includes a longitudinal housing (2) adapted to fit inside the borehole. The housing includes a first end portion (11), a second end portion (12), and a side portion (13) between said end portions (11, 12), adapted to face the sidewalls of the borehole. Means (5) are provides on the side of the housing (2) for removing material from said borehole sidewall. The housing (2) is adapted to be rotated with a controlled rotational speed in relation to said borehole sidewalls and to be fed in a controlled rate of longitudinal motion in relation to said borehole.
