Bridge plug provided with mounting anchoring mechanism and using method thereof

Abstract

The invention discloses a bridge plug provided with a mounting anchoring mechanism and a using method thereof. The bridge plug comprises a horizontally arranged bridge plug body, wherein the bridge plug body is composed of a drillable slip, a composite cone, a composite sheet and a combined rubber cylinder; the bridge plug body is sleeved with a fixed pipe body; connecting plates are fixedly connected to the top and the bottom of an inner cavity of the fixed pipe body; the other ends of the connecting plates are fixedly connected with the bridge plug body; a movable pipe body is sleeved with the fixed pipe body; a connecting pipe body is sleeved with the movable pipe body; and the bridge plug body is located in the connecting pipe body. Through mutual cooperation of a micro motor, a pinion, a large gear, a rectangular frame body, a round rod, a connecting rod, a rotating rod and other components, a fan-shaped plate can be unfolded, so that an anchoring rod can anchor and reinforce the fan-shaped plate, the falling of the fan-shaped plate caused by infirm mounting can be effectively prevented, and the working efficiency of the fan-shaped plate can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of bridge plugs, in particular to a bridge plug provided with an installation anchor mechanism and a method for using the same. Background technique [0002] The role of the bridge plug is to seal the oil and gas well, which has the characteristics of less construction procedures, short cycle time and accurate sealing position. It is divided into two types: permanent bridge plug and removable bridge plug. It is transported to the predetermined position of the wellbore by cables or pipe strings, the pressure generated by gunpowder blasting, hydraulic setting or mechanical setting tools acts on the upper slips, the pulling force acts on the tension rods, and the upper and lower cones are applied to the sealing rubber cylinder. Compression pulls two forces, and when the tension reaches a certain value, the tension rod breaks, and the setting tool is separated from the bridge plug. At this time, the locking dev...

AI Technical Summary

Problems solved by technology

[0003] However, the bridge plug of the prior art is inconvenient to adjust its position during installation, so that it cannot be installed in different environments, and it has the problem of unreliable installation, which causes it to fall off easily during use, affecting its use. We propose a bridge plug with mounting anchor mechanism and method of use thereof
