Abstract

En fremgangsmåte for å frigjøre en styreledning for en sikkerhetsventil som er fjernbart anbrakt i et brønnhulls produksjonsrørs nippel ( 9 ), som omfatter trinnene: å fjerne sikkerhetsventilen fra nippelen; å sette et tetningsverktøy ( 41 ), som tettende forbinder styreledningen ( 10 ) og et minirør ( 42 ) som løper ned inne i produksjonsrøret, inn i nippelen; å øke trykket av et fluid inn i minirøret for å forårsake at fluid strømmer inn i styreledningen gjennom tetningsverktøyet.A method of releasing a control valve for a safety valve removably disposed in the nipple (9) of a wellbore, which comprises the steps of: removing the safety valve from the nipple; inserting a sealing tool (41) sealingly connecting the guide wire (10) and a mini-tube (42) running down the production tube into the nipple; increasing the pressure of a fluid into the mini-tube to cause fluid to flow into the control line through the sealing tool.
