摘要： A method for severing a tubular of a wellbore is provided. The method involves positioning a blowout preventer about a tubular, the blowout preventer having a plurality of rams slidably positionable therein and a plurality of blades carried by the rams for engaging the tubular. The method further involves piercing the tubular with a piercing point of at least one of the blades such that a portion of the tubular is dislodged therefrom, and raking through the tubular with a cutting surface of at least one of the blades.

摘要： The invention relates to techniques for severing a tubular. A blowout preventer is provided with a housing having a bore therethrough for receiving the tubular, an actuator positionable in the housing, and a plurality of cutting tools positionable in the housing and selectively movable into an actuated position with the actuator. Each of the cutting tools have a base supportable by the actuator and selectively movable thereby, and a cutting head supported by the base. The cutting head comprising a tip having a piecing point at an end thereof and at least one cutting surface. The piercing point pierces the tubular and the cutting surfaces taper away from the piercing point for cutting through the tubular whereby the cutting head passes through tubular.

摘要： Techniques for shearing a tubular of a wellbore penetrating a subterranean formation with a blowout preventer are provided. The blowout preventer has a housing with a hole therethrough for receiving the tubular. The techniques relate to a blade assembly including a ram block movable between a non-engagement position and an engagement position about the tubular, a blade carried by the ram block for cuttingly engaging the tubular, and a retractable guide carried by the ram block and slidably movable therealong. The restractable guide has a guide surface for urging the tubular into a desired location in the blowout preventer as the ram block moves to the engagement position.

摘要： Techniques for severing a tubular of a wellbore penetrating a subterranean formation are provided. A blade is extendable by a ram of a blowout preventer positionable about the tubular. The blade includes a blade body having a front face on a side thereof facing the tubular. At least a portion of the front face has a vertical surface and at least a portion of the front face has an inclined surface. The vertical surface is perpendicular to a bottom surface of the blade body. The blade body includes a loading surface on an opposite side of the blade body to the front face. The loading surface is receivable by the ram. The blade also includes a cutting surface along at least a portion of the front face for engagement with the tubular, and a piercing point along the front face for piercing the tubular. The piercing point has a tip extending a distance from the cutting surface.
