  • APPARATUS, METHOD AND SYSTEM FOR REGULATING ANNULAR FLUID FLOW AROUND A TOOL STRING
    Publication number: 20180363396
    Abstract: A downhole tool velocity control apparatus includes a body having a portion with static circumferential diameter and a portion with a variable circumferential diameter. The portion with variable circumferential diameter has at least one velocity control member extendible radially beyond the portion with the static diameter. A method of varying the force applied by a fluid to a tool string includes traversing a tool string through a well bore using a pump fluid, the pump fluid applying a force on the tool string, monitoring a tool string characteristic, and actuating a downhole tool velocity control apparatus of the tool string to variably expand radially in response to a change in the tool string characteristic.
