Iindlela Zamazwe Ngamazwe Zokulawula Ukulahlekelwa Okubi Nokupheleleyo
Inkqubo yokujikeleza kwegazi elahlekileyo yeFoam Wedge, ekwaziyo ukuvala iimfanta ezifikelela kwi-40,000 microns, iphunyezwe ngempumelelo yiHalliburton kwizicelo zasentsimini kumazwe amabini aseMbindi Mpuma (i-Oman kunye ne-UAE).
Imingeni kwiNdalo yoKwaphuka/ukwakheka kweVugular
Ukujongana nokulahlekelwa okukhulu ukuya kuthi ga kwinani elipheleleyo leeseli eziqhekekileyo okanye eziqhekekileyo ngokwemvelo kube nzima ixesha elide, ingakumbi kuMbindi Mpuma. Izixhobo zokujikeleza kwegazi ezilahlekileyo (ii-LCM) zihlala zingaphumeleli ngenxa yokungaqiniseki ngobukhulu bomngxuma wokuqhekeka. Nangona kunjalo, iHalliburton's Foam Wedge System, edibanisa iHigh Fluid Loss Squeeze (HFLS) kunye neReticulated Foam LCM (RFLCM), ibonakalise ukuba iyasebenza, ixhaswa yimpumelelo evavanyiweyo.
Uyilo kunye novavanyo lonyango lwe-LCM lusekelwe kuvavanyo lwelebhu oluphumeleleyo, olubonisa ukuvalwa kwee-fractures ukuya kuthi ga kwi-40,000 microns.
I-HFLS kunye ne-RFLCM Dual Technology: Iziphumo zeLebhu kunye neMimandla kumazwe amabini aseMbindi Mpuma (i-Oman kunye ne-UAE)
Ezi nkcukacha ziquka iimpawu zokwakheka, ubungakanani be-wellboats, umthamo kunye noxinzelelo lwe-LCM udaka, kunye neendlela zokwenziwa kunye nokupompa ezisetyenzisiweyo. Impumelelo yokusetyenziswa ibonakaliswe ngamazinga okulahleka ngaphambi nasemva konyango phantsi kweemeko ze-wellboats ezizinzileyo nezitshintshatshintshayo, nto leyo egxininisa ixesha lokugrumba eligciniweyo.
E-Oman, injongo yayijongene nokulahleka okungashukumiyo okuya kuthi ga kwi-125 barrels ngeyure (bbl/hr) kunye nokulahleka okuguquguqukayo kwe-280 bbl/hr (550 gallons ngomzuzu, gpm) ukuya "kwilahleko iyonke." Ukwakheka kwaphawulwa yi-vugular porosity. Injongo yomthengi yayikukupompa isisombululo se-LCM esisebenzayo ukujongana nokulahleka ngokukhawuleza emva kokufikelela kubunzulu obupheleleyo (TD) kunye nokwenza imisebenzi yokugawula ngaphandle kwesidingo seeplagi zesamente, ngaloo ndlela konga ixesha lokubhoboza. Unyango lwe-HFLS kunye ne-RFLCM luxutywe emanzini, lwaphonswa kwi-circulating sub, kwaye lwafakwa kwinkqubo yokucofa ejikelezayo ngoxinzelelo olunyuka kancinci. Emva kokucofa, amazinga okulahleka okungashukumiyo kunye nokushukuma ancitshiswa ukuya kwi-zero, okuvumela imisebenzi ukuba iqhubeke ngokukhuselekileyo.
Kwi-UAE, ithagethi yayisebenzisa ulwelo lokugrumba olungenamanzi. Phantsi kweemeko ezizinzileyo, ilahleko zaziphakathi kwama-85 ukuya kuma-200 bbl/hr, ngelixa phantsi kweemeko eziguquguqukayo (amazinga okuhamba kwe-990–1250 gpm), izinga lokulahleka laliyi-150 bbl/hr. Ukwakheka kwaphawulwa kukuqhekeka okwendalo. Izixhobo ze-HFLS kunye ne-RFLCM zaxutywa kwi-oyile yesiseko, zapompelwa kwi-sub ejikelezayo, zaza zafakwa kwinkqubo yokucudiswa okujikelezayo ngoxinzelelo olunyuka kancinci kancinci. Emva kokucudiswa, izinga lokulahleka okuzinzileyo lancitshiswa laya kuma-2–15 bbl/hr, kwaye izinga lokulahleka okuguquguqukayo lancitshiswa laya kuma-25 bbl/hr (lehla laya kuma-5 bbl/hr ngexesha lokugrumba), okuvumela imisebenzi ukuba iqhubeke kwakhona.
Kwiimvavanyo zovavanyo lobuchwephesha, ukukwazi ukuvala ii-fractures/vugs ezilinganiswe elebhu ezineembobo ezifikelela kwi-40,000 microns kunike ukuzithemba kokuba indibaniselwano ye-LCM inokusingatha ubungakanani obungaqinisekanga bokuqhekeka/vug. Ukusetyenziswa kwentsimi okuphumeleleyo kusombulule ilahleko ezinkulu ukuya kwezipheleleyo, kuqinisekisa indlela ye-HFLS/RFLCM ephindwe kabini. Eyona nzuzo ibalulekileyo yetekhnoloji ye-LCM ephuculweyo kukunciphisa iindleko zokwakha izisele ngokunciphisa ixesha lokugrumba elinxulunyaniswa nokulawula ilahleko ezinkulu ukuya kwezipheleleyo.
Ukulinganisa inkqubo yokujikeleza kwegazi elahlekileyo engentla, inkampani yethu izenzele iimveliso ezimbini ngokuzimeleyo: iarhente ye-High Fluid Loss Squeeze (HFLS) i-FC-FLS kunye nearhente ye-Reticulated Foam LCM (RFLCM) i-FC-LCM, zombini ezisebenza ngokulinganayo neNkqubo ye-Foam Wedge Lost Circulation System yaseHalliburton.
