ABSTRACT:
There is disclosed a well drilling tool having a body which is connectible as part of a drill string and which includes inner and outer members which are supported for rotation with respect to one another by bearing means contained within a lubricant chamber in an annular space between the members. A series of annular, vertically stacked buckets are carried by the inner and outer members within an annular space above seal means at the upper end of the lubricant chamber, and a body of material which acts as a liquid and is contained within each of at least the upper buckets has a specific gravity substantially greater than that of drilling fluid which is circulated through a portion of the annular space above the lubricant chamber.
