Abstract
Sposób ograniczenia powierzchni ekshalacji gazu ziemnego wokół odwiertu gazowego z zastosowaniem bariery izolacyjnej, na poziomie lustra wody podziemnej charakteryzuje się tym, że nad miejscem nieszczelności kolumny eksploatacyjnej (5), w warstwie wodonośnej (3), na powierzchni zwierciadła wody podziemnej, wykonuje się w kształcie pierścienia o promieniu wewnętrznym ok. 1 metra i zewnętrznym ok. 40 metrów, symetrycznie wokół odwiertu, ukośną barierę izolacyjną (7), która wytworzona jest poprzez przewiercenie się wiertniczo - iniekcyjnym przewodem wyposażonym w systemy dysz i zatłoczeniu na poziomie zwierciadła wody warstwy wodonośnej (2) cieczy iniekcyjnej z ditlenkiem węgla, natomiast powyżej ukośnej izolacyjnej bariery (7), w warstwie (3), będącej najpłytszą warstwą geologiczną, zalegającą pomiędzy powierzchnią terenu a zwierciadłem wody podziemnej, wykonuje się żwirową, odgazowującą studzienkę (6), o głębokości sięgającej do głębokości zwierciadła wody podziemnej, w której granulacja żwiru zawiera się w przedziale od 2 do 3 mm.The method of limiting the natural gas exhalation area around the gas well with the use of an insulating barrier at the groundwater level is characterized by the fact that above the leakage point of the operating column (5), in the aquifer (3), on the surface of the groundwater table, a ring with an internal radius of approx. 1 meter and external radius of approx. 40 meters, symmetrically around the borehole, a diagonal insulating barrier (7), which is made by drilling through a drilling and injection conduit equipped with nozzles and injection at the water level of the aquifer (2 ) of the injection liquid with carbon dioxide, while above the oblique insulating barrier (7), in the layer (3), which is the shallowest geological layer, lying between the ground surface and the groundwater table, a gravel degassing well (6) with a depth of up to depth of the groundwater table in which granulation and the gravel is in the range of 2 to 3 mm.
