Embodiment Construction
[0036] The following examples describe the present invention in more detail.
[0037] 1) First, the nano-aluminum powder is transported to the gas reservoir layer through the nano-aluminum powder delivery system in the drilling pipeline, and sprayed onto the surface of the gas reservoir layer through the injection device of the delivery system;
[0038] 2) The aluminum powder is ignited under the action of the ignition system, so that the aluminum powder and ice start to react, forming an initial reaction field.
[0039] 3) The initial reaction field forms a high-temperature zone, which makes the local temperature of the gas reservoir layer rise to 2000K or higher, the equilibrium condition of the gas reservoir on the surface of the reaction zone is destroyed, and the natural gas is decomposed.
[0040] 4) At the same time, the injection device of the conveying system will continuously spray aluminum powder to the reaction zone. During the spraying process, the aluminum powder...
