Metal leakage preventing component and method thereof, and oil exploitation device

Abstract

The invention discloses a metal leakage preventing component and a method thereof, and an oil exploitation device. The metal leakage preventing component is arranged between any two adjacent flange devices, and each flange device is provided with a bolt. When the bolt is tightened, the adjacent flange devices are in a compression state, and the metal leakage preventing component generates metal extrusion to deform to form a leakproof function. The metal leakage preventing component adopts metal extrusion deformation to form a leakage preventing effect; the metal can be used for leakage prevention in a limited space by freely adjusting the size, or combined with a standard steel ring to form two protections under special circumstances. The metal leakage preventing component can also be usedunder high pressure. In the case of fracturing or poor working conditions, the surface of the leakage preventing component can achieve the sand-proof, anti-corrosive and anti-scouring effects under the condition that only two connecting members are pressed tightly. The installation is simple. The metal leakage preventing component has a simple structure and reliable form. The installation is quick and convenient, and the metal leakage preventing component can effectively prevent leakage, thus meeting the requirements of special oil fields.

Description

technical field [0001] The invention relates to the field of oil exploitation, in particular to a metal anti-leakage component, its method and oil exploitation equipment. Background technique [0002] Leakage-proof components are the most important and important components in the entire oil extraction equipment, and mainly play a role of sealing. There are R steel ring, RX steel ring and BX steel ring for conventional metal seal leak-proof, all of which are designed in accordance with API standards. [0003] Such as figure 1 As shown, in the prior art, the R steel ring sealing method or the RX steel ring sealing method is usually used in oil extraction equipment (such as the connection between two four-way components). The specific method is: first install the lower flange device 1, and then Place the R steel ring 40 / RX steel ring 40 on the upper end of the upper flange device 1, then install the upper flange device 3, and finally tighten the bolt 2, so that the upper and ...

AI Technical Summary

Problems solved by technology

[0005] Usually there is only one seal between two four-way connections, and the size is specified. In this kind of structural design, if the space is not enough, the effect of metal leakage prevention cannot be guaranteed, and a metal seal may exist in the case of fracturing. Failure, leakage, serious impact on safety
