Abstract

The invention discloses an all-metal double-slip soluble large-drift-diameter bridge plug comprising an adapter. The bridge plug is characterized in that the adapter is connected with one end of the bridge plug and penetrates through a center pipe; the bridge plug comprises a push ring (2), an upper slip (3), a cone (4), a lower slip (5), a joint (6), a fixed wire (7), a center pipe (8), a shear pin (9) and a friction bean (12). The shear pin (9) is connected with the adapter (1) and a center pipe (10). The fixed wire (7) is connected with the joint (6) and the center pipe (10). The all-metaldouble-slip soluble large-drift-diameter bridge plug has the advantages that magnesium-lithium cone replaces traditional rubber sealing material, cost is reduced, green and environmental protection effects are achieved, the structure is simple, and the size becomes smaller.

Description

technical field [0001] The invention discloses a bridge plug, which is mainly used in the fields of medicine, chemical industry, aerospace industry and oil well exploitation, and particularly relates to an all-metal double-slip soluble large-diameter bridge plug used in horizontal wells and vertical wells. Background technique [0002] The middle seal expansion part of the soluble bridge plug on the market is used for soluble rubber, and the rubber itself is poisonous, which will pollute underground oil and water sources. The product structure is complex and there are many components, resulting in long production time, high cost, complex assembly and other shortcomings. Contents of the invention [0003] In order to solve the shortcomings of existing problems, the present invention discloses an all-metal double-slip soluble large-diameter bridge plug, the adapter connects one end of the bridge plug and passes through the central tube; the bridge plug includes a push Ring ...
