摘要： A drill string shut-off valve system for controlling the mud circulation system for deepwater marine drilling operations is disclosed, the drill string shut-off valve having a valve body having a cylinder, a main flow path, and a drilling mud flow channel, an upper and a lower connector on the valve body for installing the drill string shut-off valve into a drill string, and a valve positioned to selectively interrupt in the main flow path through the valve body or to complete the main flow path through the drilling mud flow channel. A piston in the cylinder is operably connected to the valve to drive it from an open to closed position. The piston has a first pressure face, a port presenting pressure from the upstream side of the valve to the first pressure face, and a second pressure face on the back of the piston. Exhaust ports present pressure from the annulus to the second pressure face and a spring biases the drill string shut-of valve to a closed position, but balanced with the area of the first pressure face to ensure valve opening at normal pump operation pressures. A spring adjustment assembly whereby the tension of the spring can be readily adjusted to allow for different drilling conditions is also disclosed.

摘要： A one trip method for drilling a wellbore below a cemented casing is disclosed. An apparatus for use in performing the method is also disclosed. The method comprises lowering a drill bit into a casing cemented in the wellbore. The casing has float equipment connected therein. The drill bit is rotated in the casing above the float equipment so that it expands radially outwardly to a diameter greater than the inner diameter of the casing. The float equipment, which can be a float shoe or a float collar or any other type of float equipment known in the art, includes an outer case with a valve connected therein. The outer case is comprised of a drillable material. Thus, the drill bit utilized to drill the wellbore can begin its drilling operation above the float equipment and successfully drill a wellbore below the casing having a diameter greater than the inner diameter of the casing.

摘要： Apparatus and methods for a deployment valve used with an underbalanced drilling system to enhance the advantages of underbalanced drilling. The underbalanced drilling system may typically comprise elements such as a rotating blow out preventer and drilling recovery system. The deployment valve is positioned in a tubular string, such as casing, at a well bore depth at or preferably substantially below the string light point of the drilling string. When the drilling string is above the string light point then the upwardly acting forces on the drilling string become greater than downwardly acting forces such that the drilling string begins to accelerate upwardly. The deployment valve has a bore sufficiently large to allow passage of the drill bit therethrough in the open position. The deployment valve may be closed when the drill string is pulled within the casing as may be necessary to service the drill string after drilling into a reservoir having a reservoir pressure. To allow the drill string to be removed from the casing, the pressure produced by the formation can be bled off and the drill string removed for servicing. The drill string can then be reinserted, the pressure in the casing above the deployment valve applied to preferably equalize pressure above and below the valve and the drill string run into the hole for further drilling.

摘要： Methods and systems are provided for varying fluid pressure in a circulation system while circulating a kick out of a well bore 30 drilled through a subterranean formation using a drilling rig 25 and a drill string 50. The kick may be automatically circulated out of the well bore and/or a kill fluid may be circulated into the well bore. A controller 100 reduces the circulation rate by automatically controlling the rate of the pump 90 and the position of well bore choke 70. Various sensors interconnected with the controller may be used to maintain circulation system operation. The controller may control various components utilized in the circulation procedure to maintain a substantially constant bottom hole pressure on the formation while circulating the kick out of the well.

摘要： The present invention relates to bypass valves for use in wellbores, particularly but not exclusively to bypass valves used during the setting of hydraulic anchor packers. A bypass valve (2) is provided with a piston (30) slidably mounted adjacent a body member (4) having at least one opening (20) extending therethrough. The piston (30) is moveable between a first position establishing a passage from the interior of the body (4) to the exterior thereof via the at least one opening (20) and a second position isolating the interior of the body (4) from the exterior thereof. A second piston may be provided for increasing, in response to a predetermined fluid pressure differential across the length of the piston (30), the force exerted on the piston (30) by a given flow of fluid through the bypass valve (2) such that the resultant force on the piston (30) is insufficient to move the piston (30) to the second position. Thus, the bypass valve (2) is adapted to provide an indication at the surface of an imminent closure. Once the indication is received, the bypass valve (2) may be closed, without the need for remedial action, by simply increasing the rate of fluid flow.

摘要： A by-pass valve is part of an apparatus arranged to function as a serial element of a drill string. An arbor is attached to the top end of a tubular motor rotor and extends some distance along the generally central opening of the housing which is attached to the top end of the motor housing. A head on the arbor comprises a normally closed valve which is capable of conducting fluid from inside the housing to the well annulus outside the drill string by way of the bore of the tubular rotor. The valve is opened by downward movement, in excess of a selected amount, of the rotor of the motor. The excessive downward movement of the rotor indicates problems in the motor bearing structure, or disruptive failure elsewhere in the bottom hole assembly. The opening of the by-pass valve reduces standpipe pressure which is a signal detectable at the surface. The signal indicates disruptive failure in the down hole assembly.

摘要： A flow rate control device (18) placed at the bottom of an oil well in production comprises holes (24) formed in the production tubing (16), a closure sleeve (26) suitable for sliding over the holes (24) for controlling the flow rate, and a protective sleeve (34). The protective sleeve (34) is urged by a return spring (36) into a position in which it covers a sealing gasket (32). During closure of the device (18), the two sleeves come into edge-to-edge abutment and the closure sleeve (26) pushes the protective sleeve (34) back against the return spring (36). The sealing gasket (32) is never in direct contact with the fluid in the well. Preferably, the closure sleeve (26) is mounted on the outside of the production tubing (16).

摘要： A method of enclosing an oil drilling rig. A first step involves providing a base and a flexible sheet-form covering having a first edge and second edge. A second step involves securing the base to the oil drilling rig and securing the first edge of the covering around a perimeter of the base. A third step involves securing the second edge of the covering to the drilling rig in spaced relation to the base, thereby maintaining the covering in a substantially taut condition forming a tubular enclosure.
