Abstract

1,270,056. Drilling wells. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 30 June, 1970 [7 July, 1969], No. 31595/70. Heading E1F. A well head packing suitable for underwater wells comprises movable seals 11 adapted to engage about he whole circumference of a drill pipe 3 or other member passing through the well head, and a pair of seals 12 connected to each of the seals 11 and arranged to seal the junction between the seals 11 when these are engaged with the pipe or member. The seals 11 and 12 are urged into sealing position by rams 17, resilient members 25, 15 permitting the pairs of seals 12 to yieldably engage one another before the seals 11 yieldably engage the pipe or member, the seals 12 and one another. The drill pipe may be a flexible one. (For Figures see next column)
