COLLAR LOAD SUPPORT SYSTEM AND METHOD

摘要

A wellbore tubular handling system and method is provided for operation in holding and lowering tubulars, such as tubing strings, casing strings, pipe strings, and the various components thereof, at a rig site. The handling system utilizes a shock table (10) with a compressible support surface (20) that compressively moves with a selected compression rate in response to the weight of the wellbore tubular string (24). The shock table (10) preferably has a shock table body (16) mounted below the rig floor (12) and supports th e shock table (10) with a flange (14). A split-sectioned landing spear (30, wh en open, can allow large items such as collars of other string components to pa ss through the shock table (10). In a closed position, the landing spear (30) supports and upper collar (34) of the string (24) to thereby support the weight of the string (24) and apply the weight to the compressible support surface (20) of the shock table (10).
