WELL PACKER FOR A PIPE STRING AND A METHOD OF LEADING A LINE PAST THE WELL PACKER

摘要

The invention concerns an external well packer ( 4, 4', 4 '') for a pipe string ( 2 ), and also a method of leading at least one line ( 18 ) seamlessly past at least one packer ( 4, 4', 4 '') along the pipe string ( 2 ). What is characteristic of the packer ( 4, 4', 4 '') is that it consists of a continuous inner packer ring ( 8 ) and a separate and continuous outer packer ring ( 10 ), which in the operating position encloses the inner packer ring ( 8 ) in a pressure tight manner. The fitting surface of at least one of the packer rings ( 8, 10 ) is provided with at least one through-going line slot ( 16, 16 '), which in the operating position encloses a line ( 18 ) in a pressure tight manner. This allows continuous lines ( 18 ) to be stretched out past several such packers ( 4, 4', 4 '').
