specific Embodiment

[0056] In practical applications, the user pushes the slider 4 to move upward through the hydraulic oil inlet and outlet port 5 and squeezes the second deformation part 22, wherein the elastic deformation part 222 in the second deformation part 22 is deformed, and the elastic deformation part 222 is deformed through transmission. The force convex head 223 squeezes the extruded sealing part 221, and the extruded sealing part 221 deforms to the side of the drill string 6, squeezes and hugs the drill string 6 to seal and realize blowout prevention, as attached image 3 As shown; the slider 4 continues to push upwards under the action of the oil inlet and outlet of the hydraulic oil inlet and outlet 5, wherein the first deformation part 21 is deformed, the sealing guide bowl 31 of the second sealing blowout prevention part 3 guides and moves, and the slider 4 moves and pushes The sealing guide bowl 31 moves and hugs tightly to realize blowout prevention.

Abstract

The invention discloses a composite metal material sealed inner blowout preventer, which comprises an inner blowout preventer body, the inner blowout preventer body includes a first seal blowout preventer and a second seal blowout preventer, the first seal blowout preventer The spray part is connected with the second sealing blowout prevention part, and both of them are in contact with the slide block provided on the inner blowout prevention tool body. The slide block is provided with a hydraulic oil inlet and outlet, and the hydraulic oil inlet and outlet push the oil in and out respectively. The slider moves up and down, and the slider stays in different positions, which can deform the first sealed blowout preventer and / or the second sealed blowout preventer to implement blowout prevention or release blowout prevention. The first sealed blowout preventer and the second seal blowout preventer The two sealing blowout prevention parts are casted from tin bronze. The present invention is made of tin bronze metal casting or machining, and the interior is a hollow structure. On the one hand, the size is accurate, the sealing pressure is accurate, and the sealing effect is good. On the other hand, it can be repeatedly disassembled and recycled. Adjust the size of the holding force according to your needs.

Description

technical field [0001] The invention relates to the field of internal blowout prevention tools, in particular to a composite metal material sealed internal blowout prevention tool. Background technique [0002] During the drilling process, when overflow kick occurs in the well, in order to prevent the formation fluid and drilling fluid from spraying up along the drill string water hole and damaging the hose and causing blowout, it is necessary to use the blowout prevention tool in the drill string to control the internal pressure of the drill string. [0003] At present, the blowout prevention tool in the oil pipe (drill pipe) is widely used in oil well operations. Blowout prevention tool in the tubing; the blowout prevention tool in the tubing is composed of the upper lifting short and the tubing cock valve connected to the lower part; the kelly cock valve, which belongs to the blowout prevention tool in the drill pipe, usually has two types: the upper cock valve and the lo...
