发明名称 EXTENDED REACH PLACEMENT OF WELLBORE COMPLETIONS
摘要 A self-actuated cyclical flow interruption valve on a deployment tool is positioned at a proximal end of a well completion assembly. Fluid is pumped though the self-actuated cyclical flow interruption valve and vented immediately distal of the valve, to return to surface of the well. A water hammer pulse is generated each time the self-actuated cyclical flow interruption valve closes, thereby generating an impact force that acts to push the completion equipment distally into the well. The continuous cyclic force of the impact facilitates placement of the completion equipment where desired in the well, including within a horizontal extension of the well. Fluid discharged through the self-actuated cyclical flow interruption valve circulates up to the surface through a vertical and inclined section of the well.
