Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-2 , One-time fracturing expansion tube, including shell 1 and first plug 2 and second plug 3 at both ends of shell 1. Both ends of shell 1 are provided with screw holes, and the center of second plug 3 is provided with a central hole. A plug 2 is completely sealed, which can separate the gas in the expansion tube from the gas outside the expansion tube. A gas generator 4 is provided in the casing 1, and the gas generator 4 is fixed inside the casing 1 through a bracket. A gas generating agent 5 is provided, a trigger device 6 is provided in the middle of the gas generator 4, and a wire 7 is connected to both ends ...

Abstract

The invention discloses a disposable fracturing expansion pipe and a fracturing method thereof, and belongs to the technical field of expansion pipes. The disposable fracturing expansion pipe mainly comprises a shell, and a first plug and a second plug at two ends of the shell; screw holes are formed in the two ends of the shell; a central hole is formed in the center of the second plug; a gas generator is arranged in the shell; a gas generating agent is arranged in the gas generator; a triggering device is arranged in the middle of the gas generator; two ends of the triggering device are connected with conducting wires; and the conducting wires penetrate through the two ends of the gas generator, pass through the central hole and extend out of the expansion pipe. During use, the expansionpipe is placed in a drilling hole, the drilling hole is blocked with a stopper, then the expansion pipe is inflated with gas, and finally, an exploder is started to ignite the gas generating agent, so that the expansion pipe is exploded. The disposable fracturing expansion pipe provided by the invention has the characteristics of being small in size, convenient to transport, safe in use, and controllable in power, the fracturing method is simple, and fracturing expansion pipe is applied to the fields of mining, oil exploitation, hydraulic engineering construction and electric power engineering construction, and the like.

Description

Technical field [0001] The invention relates to the technical field of an expansion tube and a cracking method thereof, in particular to an expansion tube for disposable cracking and a cracking method thereof. Background technique [0002] Traditional blasting uses explosive blasting, and its energy is rapidly released in a limited space, generating a shock wave with extremely high pressure (up to thousands of MPa) and spreading outward. The shock wave propagates to a distance and attenuates into a seismic wave. The energy of blasting vibration waves accounts for about 2% to 6% of the explosive energy released by explosives. Severe blasting seismic effects can cause damage to rock structures (such as slopes) and building structures, affecting the lives of nearby buildings and personnel. [0003] At present, the main rock breaking method from mine mining to bridge building and road construction and urban infrastructure construction also includes a technology that uses carbon dioxide...
