Patent ID: 11879309

Abstract:
A method is described for supply of liquid from a liquid storage to a casing string (10,12, 14..) which from a deck (16) on an installation is conveyed down in a well with the help of a pipe handler comprising an elevator, where the liquid is supplied via an uppermost casing (10) which is added to the casing string, and the liquid is supplied through a filling pipe (30) via an outlet nozzle (36) to the top of the casing (10) already during the pipe's (10) screwing into the casing string (10, 12, 14..) where the filling pipe is extended during the liquid supply until the casing string is being lowered down to a position where it is securely locked to the deck (16), and liquid is added to a suitable level in the casing string. The method is characterised in that the filling pipe (30) is extended in that it comprises a telescopic axially moveable pipe end part (35) with a constricted outlet (36) which leads to the pipe end part (35) being pushed axially outwards and extends the filling pipe (30) when the liquid is supplied under pressure, and the pipe end part (35) is pushed outwards under the counter effect of a prestressing force, and pulled back under the influence of said prestressing force when the liquid supply stops. Also described is a device as given in claim 10.
