Embodiment Construction

[0024] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0025] The structure of composite material speed drilling bridge plug, such as Figure 1-3 As shown, the shaft 1 has a length of 622.5mm, an outer diameter of 75mm, and an inner diameter of 25mm. An end shaft 8 is provided on the outer surface of the bottom end of the shaft 1, and the outer diameter of the end shaft 8 is 112mm. A plug 9 is installed in the pin 13 at the top of the shaft 1. The plug 9 and the shaft 1 are sealed by a sealing ring 10, the size of the sealing ring 10 is 25×2.65mm; the first slip seat 4 and the second The slip seat 6 is fixed on the shaft 1 by four set screws 11, the sealing ring 12 is installed between the first slip seat 4 and the second slip seat 6, and the sealing ring 12 is connected to the first slip seat 4 , The second slip seat 6 is provided with a transition shoe 5, the first slip seat 4 is connected to one end of the fir...

Abstract

The invention discloses a fast drilling bridge plug made of a composite material, belonging to the technical field of oil and gas field exploitation. The fast drilling bridge plug comprises a shaft lever made of a epoxy glass fiber composite material, wherein an end shaft is arranged on the outer surface of the bottom end of the shaft lever; a plug is arranged at the axis of the top end of the shaft lever; the plug and the shaft lever are sealed by a sealing ring; a first slip bowl and a second slip bowl are fixed on the shaft lever; the sealing ring is mounted between the first slip bowl and the second slip bowl; transition tiles are arranged among the sealing ring and the first slip bowl as well as between the sealing ring and the second slip bowl; the first slip bowl is connected with one end of a first slip made of a metal material; the other end of the first slip is connected with a thrust ring; the second slip bowl is connected with one end of a second slip made of a metal material; and the other end of the second slip is connected with the end shaft. According to the bridge plug disclosed by the invention, the problems in the prior art that drill beating and jamming of a drilling tool easily occur during bridge plug drilling, the bridge plug chips cannot flow back easily and the construction efficiency is low are solved.

Description

Technical field [0001] The invention belongs to the technical field of oil and gas field exploitation and relates to a composite material speed drill bridge plug. Background technique [0002] At present, after large-scale exploitation of domestic oil and gas fields, oil-rich areas have been scarce or even exhausted, leaving a large number of low-permeability oil areas without large-scale exploitation. The main reason is that the oil production is low and the income is not enough. In recent years, the use of hydraulic fracturing technology for shale gas exploitation and secondary development of low-permeability oil areas has greatly increased the amount of bridge plugs used. Because they are consumables that can only be used once, the amount is huge. At present, the main metal bridge plugs used in China have been used for more than half a century and have made a great contribution to my country's oil production, but there are also many problems. [0003] 1. Card, drill. When the ...
