ActiveCN120211643Bshort response timeImprove blowout prevention abilityDrilling rodsDrilling casingsPetroleum oilMechanical engineering
This invention relates to the field of oil extraction technology and discloses an oil extraction drill pipe fixing device, including a support base. A limiting block is fixedly connected to the side wall of the support base. During the placement of the slips, the slider is subjected to the squeezing force from the support base, and the slip slides relative to the support base. After sliding along the inclined surface, the horizontal straight distance between the bottom of the slider and the limiting block becomes shorter, and the limiting block can just hold the bottom of the slider. After placement, the limiting rod is pushed to slide into the limiting groove, so that the limiting can be performed at the same time as the slip is installed. When it is removed after use, the operation can be reversed. This avoids the slip being subjected to a large upward impact force that would quickly push the slip out of the wellhead when the well pressure is too high or during a blowout, thus reducing the response time and improving the slip's blowout prevention capability and extending the response time.
