摘要： There is provided a downhole tool that can be used to grind down and remove scale and debris that has built up within a wellbore. The downhole tool has a drill bit that has an outer surface for engaging a wellbore and defines a bit bore. The drill bit has a first end defining a bit face and a second end adapted to engage a drive pipe. The drill bit also has a projection coupled to the outer surface of the drill bit, the projection being adapted to remove debris from a wellbore. In some cases, the projection comprises a plurality of projections. Generally, the scale and debris are at least partially removed from the wellbore when ground down by the downhole tool comprising the projection.

摘要： There is provided a tubing joint for use in breaking up scale and debris in fluids circulating within an oil, gas, water or other well to prevent clogging. The tubing joint has a tubular that defines a bore through which fluids flow, and a projection coupled to the tubular and extending into the bore. In some cases, the projection comprises a plurality of projections. The projection forms a partial obstruction within the bore of the tubing joint, against which scale and debris impact as they are carried by the fluid through the bore. Generally, the scale and debris break apart into smaller pieces upon impact, preventing the scale and debris from building up and causing a clog within the oil, gas water or other well.
