Method for delivering or for preparing the delivery of fluid media

Abstract

The present invention relates to a method for recovering or preparing to recover fluid media from underground reservoirs, which enables hitherto non-profitable reservoirs (mini-cavities) containing fluid media to be joined up underground to form a commercially viable reservoir. This object is established according to the invention by a method, is set forth in claim 1. for recovering or preparing to recover fluid media from underground reservoirs and comprising the following steps: sinking at least two substantially vertical boreholes or shafts into the earth's surface introducing at least one pipe consisting of at least one section into each of the vertical boreholes or shafts, the at least one section of pipe having at least one opening in the lower portion of its wall, the openings in the sections of the at least two pipes each being aligned with a selected point between two pipes and this point being located between the at least two substantially vertical boreholes. lowering an explosive charge to a desired depth in the pipe and detonating the explosive.

1 : Method for recovering or preparing to recover fluid media ( 1 ) from underground reservoirs ( 2 ), at least two vertical boreholes ( 3 ) or shafts ( 4 ) being sunk into the earth's surface ( 5 ) and at least one pipe ( 6 ) comprising at least one section ( 6   a - 6   c ) being introduced into each of the vertical boreholes ( 3 ) or shafts ( 4 ), comprising the steps of:
 lowering an explosive charge ( 10   a ) to a desired depth ( 11 ) in the pipe ( 6 ) of the respective borehole, the at least one section ( 6   a ) of the pipe ( 6 ) having an opening ( 8 ) in the lower portion of its wall ( 7 ), the openings ( 8 ) in the sections ( 6   a ) of the at least two pipes each being aligned with a selected area ( 9 ) between two pipes, this area ( 9 ) being located between the at least two vertical boreholes ( 3 ) and the desired depth ( 11 ) being the depth of the at least one opening ( 8 ) in the at least one section of the pipe ( 6   a ) inserted in each case into the vertical borehole or shaft, and   detonating the respective explosive charge ( 10   a ).   
     
     
         2 : Method for recovering or preparing to recover fluid media ( 1 ) from underground reservoirs ( 2 ), at least two vertical boreholes ( 3 ) or shafts ( 4 ) being sunk into the earth's surface ( 5 ), comprising the steps of:
 introducing a wall liner into each of the vertical boreholes ( 3 ) or shafts ( 4 ),   sinking of a first explosive charge ( 10   b ) to a desired depth ( 11 ) in each of the boreholes ( 3 ) or shafts ( 4 ), the desired depth being the depth at which it is intended to subsequently detonate the second explosive charge for horizontal propagation of the pressure wave,   detonating the first explosive charge ( 10   b ) at the desired depth ( 11 ) in such a manner that holes are created in the wall liner by the detonation of the first explosive charge,   lowering a second explosive charge ( 10   a ) to the desired depth ( 11 ) in each of the boreholes ( 3 ) or shafts ( 4 ), and   detonating the second explosive charge ( 10   a ) at the desired depth ( 11 ).   
     
     
         3 : Method according to  claim 1 , wherein the fluid media ( 1 ) are liquid or gaseous organic hydrocarbon compounds ( 13 ). 
     
     
         4 : Method according to  claim 1 , wherein the explosive charge ( 10   a ;  10   b ) is lowered in a blasting device ( 18 ). 
     
     
         5 : Method according to  claim 4 , wherein the blasting device ( 18 ) is reinforced, at least at the top or bottom thereof, with a blast-resistant or explosion-proof material ( 14 ). 
     
     
         6 : Method according to  claim 4 , wherein the blasting device ( 18 ) comprises a bleat-resistant or explosion-proof material ( 14 ) or is reinforced completely with a blast-resistant or explosion-proof material ( 14 ), and wherein the blasting device ( 18 ) is adapted, at least in part, to the internal geometry of the pipe ( 6 ) or of the wall liner ( 12 ) and has at least one blast opening ( 19 ). 
     
     
         7 : Method according to  claim 1 , wherein the step of detonating the explosive ( 10   a ) in the at least two substantially vertical boreholes ( 3 ) or shafts ( 4 ) is mutually coordinated. 
     
     
         8 : Method according to  claim 2 , wherein, after the step of introducing a Wall liner ( 12 ), said wall liner ( 12 ) is partially reinforced with a blast-resistant or explosion-proof material ( 14 ) in the area of the desired depth ( 11 ). 
     
     
         9 : Method according to  claim 1 , wherein the section ( 6   c ) of the pipe ( 6 ), which has at least one opening ( 8 ) in the lower portion of its wall ( 7 ), is at least partially reinforced with a blast-resistant or explosion-proof material ( 14 ). 
     
     
         10 : Method according to  claim 1 , wherein the section ( 6   c ) of the pipe ( 6 ), which has at least one opening ( 8 ) in the lower portion of its wall ( 7 ), comprises a blast-resistant or explosion-proof material ( 14 ).
