TOOL AND METHOD FOR USE IN SUPPORTING A SUCKER ROD STRING IN AN OIL OR GAS WELL

摘要

A tool for use in suspending operation of an oil or gas well driven by an artificial lift with a polished rod connected to a sucker rod in a tubing string includes a body having a lower narrow portion dimensioned to fit within the interior cavity of a tubing string inlet or an upper extension thereof; an upper wide diameter portion defining a substantially horizontal landing surface dimensioned to rest upon the top edge of the tubing string inlet or the upper extension thereof; one or more sucker rod-engaging structures; and one or more longitudinal slots extending through the lower narrow portion and the upper wide diameter portion to allow passage of fluid or gas through the tool when the tool is supported on the top edge of the tubing string inlet or the upper extension thereof.

1. A method for supporting a sucker rod string and associated downhole pumping equipment on a tubing string inlet or an upper extension thereof, during preparation of a wellhead for suspension of an oil or gas well, the method comprising:
a) lifting and supporting the sucker rod string and partially disassembling the wellhead to expose an uphole end of the sucker rod assembly; b) engaging a support tool to a portion of the uphole end of the sucker rod assembly, the support tool having:
i) an upper wide diameter portion with a substantially horizontal landing surface wider than the inner diameter of the tubing string inlet or the upper extension thereof; andii) a lower narrow portion configured to fit inside the tubing string inlet or the upper extension thereof; and c) lowering the sucker rod string into the tubing string inlet or the upper extension thereof, until the lower narrow portion enters the tubing string inlet or the upper extension thereof, and the landing surface of the support tool rests upon the top edge of the tubing string inlet or the top edge of the upper extension thereof.
