AN APPARATUS FOR STOPPING A BLOWOUT FROM AN OIL OR GAS WELL

摘要

An apparatus for stopping an uncontrolled blowout from an oil or gas source, especially in connection with extinction of a burning oil well on land. The apparatus comprises a delimiting member (18) for placing on the ground (4) around the well opening (5), the delimiting member (18) having first and second passages (30 resp. 31) for through-flow of the fluid escaping from the well. Further, the apparatus comprises a rail means (2, 3, 13, 14) for temporary placing on the ground (4), for rail-controlled guiding of the delimiting member (18) to a centered position above the well opening (5) in which position the opening is aligned with the first passage (30), and a means (10) for controlled lowering of the delimiting member (18) to the ground (4) in the centered position. The delimiting member (18) is a solid block element which has a substantially weight and wherein there is installed a valve means (25) having a slide element (28) which is arranged to shut off the first passage (30) during simultaneous opening of the second passage (31).
