ABSTRACT:
A well tool positioner is adapted for positioning the tool in a desired relation within a well pipe. The positioner includes a generally cylindrical resilient body adapted to be closely mounted around a tool with the major outside diameter of the body being substantially no larger than the outside diameter of the tool. At least three support vanes are formed with the body as an integral member with each vane being generally ellipsoidal in cross-section and extending perpendicular from the axis of the body and with the major axis of the generally ellipsoidal shape extending along the axis of the body. The body defines an exterior annular recess in the vicinity of the support vanes such that the recess provides an increase in effective flow area between the body and the outer tips of the vanes which at least partially compensates for the decrease of such flow area as caused by the total thickness of the vanes.
