Shale khase - eketsehileng mohloli oa matla le mathata

khase Shale ke mofuta oa khase ea tlhaho, e entsoe ka likaroloana bogolosegolo ea methane e le concentrated shales.

Shale lefika bitsoa phutha dikarolo 'maloa e tšoanang le ho ea liminerale tlaase mocheso (chlorite, sericite, actinolite, muscovite et al a.).

Tsena majoe bokhoni ba bath ho habonolo aroha lipoleiti eaba ba etsa sebaka (babokelli) pakeng tsa tse bakoang ke khase shale.

babokelli ba motho ka mong ha mehloli khase ea ruileng, empa, leha ho le joalo, ba ile ba ba lekaneng ho hlophisa tlhahiso ea khoebo.

mobung Shale fumana mong le e mong le k'honthinente, hore naha ka etsa leha e le efe e seng ea hloka botsitso, ho fana ka maruo hlokahala.

Tse qotsitsoeng ea theko ena khase e phahameng ka lebaka la ho 'nete ea hore qalong e neng e amana le se qalang tsa libakeng tse khōlō, ho sebelisoa haeteroliki fracturing thekenoloji (haeteroliki pokello) le ho cheka kamehla mekoti e telele ka bongata, ho bōpa ka ho bona sa khoa tsa khase pompa.

tlhahiso ea khase

Pele khoebo tlhahiso ea khase e tsoang mobung shale United States phethile.

Hamorao ba ntlafala theknoloji, kopantseng paatsepama le rapaletseng cheka, e fokolitse litšenyehelo tsa khase.

Kajeno shale khase tse hlahisoang ke ho phetha ho cheka liliba paatsepama kapa tse tshekaletseng sebelisa multiotvodov ka botebo e tšoanang le liliba multistage (tshekaletseng) ka le sehokelo ho fihlela ho km tse tharo.

Technology fana shale khase ente liliba e ile ea fata ka motsoako oa metsi, ho lata lehlabathe le lik'hemik'hale. Metsi hamore le hlaha, e leng ho roba fatše marako khase pokello, e leng lumella ho di-pump ho holim 'a khase tsohle fumaneha.

Horizontal cheka thekenoloji sebedisa e popontshwa le mokhoa 3DGEO litšisinyeho tsa lefatše modelling, e kopanya lithuto tsa Geological le dimmapa le ho e lokisa ya khomphuta ya hao ya tlhahisoleseding, ho akarelletsa le lits'oants'o.

Shale khase thepa

Litšenyehelo tsa tlhahiso ea khase e laolwang ke litsupa joalo:

- dikahare tsa lehlabathe o boima oa letsopa, e khona ho monya matla ea fracture le, e leng eketsa ka tjhelete e ya lik'hemik'hale sebelisoa le ama theko;

- sebabole dioxide e (ka tlaase sekhahla kenyelletsoa ha lintlha tsa khase sebabole dioxide e eketsa sekhahla ka ho kenya tshebetsong le);

- kerogen dikahare;

- ditjeo tlhahiso ea ka shales teteaneng le thermally matla bao e leng Paleozoic le Mesozoic nako;

- pontšo ea litaba tse ka hare ya silica (e phahameng ha e le shale feta brittle le theola litšenyehelo).

- shale liliba tse ka tlaase ho moo tsoarellang ka sebelisoa ho feta tloaelehileng;

- e ile ea fata liliba fokotsa sekhahla phallo ka potlako haholo - ka 30-40% ka selemo;

- ea boholo-holo shale mobung na maemo a phahameng a le mahlaseli a sa gamma, e leng eketsa ea semelo sa mahlaseli ka lebaka la fracture ena.

Tikoloho le shale khase

Ha shale khase ke thekenoloji o teng e ke ke ea e solofetsang mefuta e meng ea ho tlhaho.
