Apparatus for rapidly terminating flow through a well upon sensing of an unsafe well condition. A housing surrounds the well casing and defines a chamber within which a blade is located with its cutting edge adjacent the well casing. An explosive charge positioned against the blade is electrically connected to sensors in the area of the well outlet. When a sensor detects an unsafe condition, the explosive charge is initiated, driving the blade through the well casing without crushing of the casing. When the unsafe condition is corrected, a plug is withdrawn, permitting retraction of the blade and replacement of the explosive charge, thus making the apparatus ready for reuse.

The invention relates to a marine apparatus which includes a clamping device that is submergible beneath the water''s surface to be aligned with, and to squeezably deform the upstanding well casing of an uncontrollably flowing well. The apparatus includes a clamping yoke having spaced apart arms which define an opening or slip for registering about the upstanding well casing. A pair of displaceable cross members extend from the termini of the arms to interlock with each other and to engage the well casing. A hydraulic cylinder carried on the yoke is adapted to urge the clamping device into contact with the casing whereby to deform and crush the latter against the interlocked cross members.

A blow-out preventer comprising a relatively large body means which is placed in a well bore. The body means is provided with a bore through which drill pipe and the like can extend. Traversing the bore through the body is a slideway in which is mounted a slide or blocking means. Using a suitable means of propulsion, the slide or blocking means can be moved from a position from within the slideway of non-engagement with the bore extending through the body to a position where the slide completely intersects or blocks the bore in the body. The propulsion means can be activated automatically or manually from the surface or automatically from below the surface. When the blowout preventer is used in well bores wherein drill strings or production tubing extend through the body, the apparatus is provided with a severing means which first acts to sever the pipe extending through the bore at which point the slide or blocking means is forced through the space between the severed end to completely seal off the well bore. In cases where no drill pipe or the like extends through the bore of the body means, the severing means can be dispensed with and the well bore blocked off simply by propelling the slide into the closed position, i.e. intersecting the bore.

Uncontrolled flow of oil and gas from petroleum wells located in a body of water, is stopped by a procedure performed below the water surface at a location which is free from wave action and is safe from the danger of fire or explosion. An access conduit line is hot-tapped into the production tubing through access windows formed in the well casing. The production tubing is then crimped above the hot tap and solid particles are then introduced into the production tubing through the access line where they are carried upwardly by the flowing well fluids to lodge within the restriction and form a plug. Heavy, noncombustible ''''mud'''' is then pumped into the tubing through the access line until the weight of the injected mud overcomes the formation pressure, thus terminating well flow. Where the well is located on land, the method of the present invention may be practiced by obtaining access t the well structure at the point below the land surface for formation of the hot tap and crimp.

A hinged housing can be opened and then closed around a well casing with a tight seal. A rotary cutter disc is slidably mounted in the housing and operates to cut through the well casing within the housing and to polish the upper end of that part of the severed casing extending into the well. Hydraulic means are then actuated to press a face of the cutter disc against the polished end of the casing to positively close and seal the well.

A knife blade is carried by each of the two rams of the ram assembly of a blowout preventer. The knife blades overlap when the rams are closed with the cutting edge of one knife blade passing just below the cutting edge of the other knife blade to shear a pipe string extending through the preventer. Each knife blade engages a seal member on the other ram, when the rams are closed, to form two vertically spaced seals between the engaging faces of the rams.

A safety valve assembly for extradition of hydrocarbons includes a valve body including a passage duct, configured to be traversed by a production and/or drilling line. The valve body includes housings for a punch and counter-punch, arranged diametrically opposite to one another with a common longitudinal axis substantially perpendicular to the longitudinal axis of the valve. The punch slides linearly in a controlled manner in the housing along the axis which intersects the longitudinal axis of the pipe, and the counter-punch slides linearly in a controlled manner in the housing along the axis which intersects the longitudinal axis of the pipe. The punch and counter-punch are configured to allow the counter-punch to slidingly receive the punch in its interior to create two different shearing planes. The counter-punch includes a hollow part to slidingly receive the section of tubular material and the punch, in the linear movement during the shearing operation. |
