The method of extracting hydrocarbons from a shale gas deposit and a device for extracting hydrocarbons from a shale gas deposit

Abstract

A device and method of extracting gas from the gas shale deposit by the partial combustion of hydrocarbons in the deposit in air is described. The method and device uses a gas extraction process and a pyrolysis process. The amount of air is controlled during the pyrolysis process to manage the process and to discharge effluent from the deposit.

         5 . A method of extracting hydrocarbons from a shale gas deposit involving the supply of air to the deposit, then igniting the deposit in order to bring about the effect of pyrolysis through partial combustion of hydrocarbons and then extracting the gas to the surface of the earth, comprising:
 a process of supplying flammable materials and air to the shale gas deposit and next discharging products of evaporation and pyrolysis of shale gas deposit is carried out with use of a single transporting conduit, favorably a pipeline or a supply shaft; wherein amount of air supplied through the single transporting conduit to the shale gas deposit is adjusted so as to ensure conversion of hydrocarbons in a liquid state into a gaseous state and hydrocarbons in a solid state into a gaseous and liquid state.   
     
     
         6 . A method according to  claim 5 , wherein the amount of air supplied through the pipeline or the supply shaft, which air is used to support partial combustion of hydrocarbons and the amount of hydrocarbons discharged from the shale gas deposit by this pipeline is controlled alternately by means of a valve installed on the pipe and a valve installed on the pipe. 
     
     
         7 . A device for extracting hydrocarbons from the shale gas deposit comprising: a pipeline wherein the pipeline has an air-tight permanent forefoot and is equipped with an air-tight hatch, through which a combustible material is provided to start the burning of hydrocarbons within the shale gas deposit, then with the pipe supplying air at increased pressure equipped with a valve controlling the amount and pressure of air supplied, with the pipe discharging the products from the shale gas deposit resulting from the partial combustion of hydrocarbons equipped with a pressure gauge valve, additionally the pipeline, has the openings facilitating the supply of air to the shale gas deposit and facilitating the discharging of the products of partial combustion of the shale gas deposit to the surface of the earth. 
     
     
         8 . A device according to  claim 7 , wherein the transporting shaft performs the functions of the pipeline.
