Abstract

The invention discloses a full-metal single-slip soluble large-drift-diameter bridge plug. The full-metal single-slip soluble large-drift-diameter bridge plug comprises an adaptor. The full-metal single-slip soluble large-drift-diameter bridge plug is characterized in that the adapter (1) is connected to one end of the bridge plug and penetrates through a central pipe; the bridge plug comprises apush ring (2), a slip (3), a cone (4), a first clamp ring (5), a second clamp ring (6), a joint (8), a fixing wire (9), a center pipe (10), a shear nail (11), a left hoop ring (12) and a right hoop ring (13); the shear nail (11) is connected with the adapter (1) and a central pipe (10); and the fixing wire (9) fixes the joint (8) and the central pipe (10). The full-metal single-slip soluble large-drift-diameter bridge plug has the advantages of convenient and simplified construction process, simple structure, small volume, intelligent water dissolution, cost saving, precise positioning, prevention of setting in advance, safety and high quality performance. The invention is mainly used for oil and gas well exploitation, in particular to the full-metal single-slip soluble large-drift-diameter bridge plug for horizontal wells and vertical wells.
