Izindlela Zamazwe Ngamazwe Zokulawula Ukulahlekelwa Okukhulu Nokuphelele
Uhlelo Lokujikeleza Olulahlekile Lwe-Foam Wedge, olukwazi ukuvala ama-fracture afinyelela kuma-micron angu-40,000, lusetshenziswe ngempumelelo yiHalliburton ezinhlotsheni zasensimini emazweni amabili aseMpumalanga Ephakathi (i-Oman ne-UAE).
Izinselele Ekwakhekeni Kwemvelo Kokuphuka/Ukuqhekeka Kwesikhumba
Ukubhekana nokulahlekelwa okukhulu kuya kokuphelele ekwakhekeni okuqhekekile ngokwemvelo noma okuqhekekile sekuyisikhathi eside kuyinselele, ikakhulukazi eMpumalanga Ephakathi. Izinto zokujikeleza kwegazi ezilahlekile ezivamile (ama-LCM) zivame ukwehluleka ngenxa yokungaqiniseki ngobukhulu bokuvuleka kokuqhekeka. Kodwa-ke, i-Halliburton's Foam Wedge System, ehlanganisa i-High Fluid Loss Squeeze (HFLS) kanye ne-Reticulated Foam LCM (RFLCM), ibonakale isebenza kahle, isekelwa yimpumelelo evivinywe ensimini.
Ukwakhiwa nokuhlolwa kokwelashwa kwe-LCM kwakusekelwe ekuhlolweni kwelebhu okuphumelelayo, okubonisa ukuvalwa kwama-fractures afinyelela kuma-microns angu-40,000.
Ubuchwepheshe Obumbili be-HFLS kanye ne-RFLCM: Imiphumela Yelebhu kanye Neyensimu Emazweni Amabili aseMpumalanga Ephakathi (i-Oman kanye ne-UAE)
Le mininingwane ifaka phakathi izici zokwakheka, usayizi we-wellbor, ivolumu kanye nokuhlushwa kodaka lwe-LCM, kanye nezindlela zokwakheka kanye nokupompa ezisetshenzisiwe. Impumelelo yokusetshenziswa iboniswe amazinga okulahlekelwa ngaphambi nangemva kokwelashwa ngaphansi kwezimo ze-wellbor ezimile neziguquguqukayo, okugqamisa isikhathi sokubhoboza esilondoloziwe.
E-Oman, inhloso ihlangabezane kahle nokulahlekelwa okungaguquki kwama-barrel angu-125 ngehora (bbl/hr) kanye nokulahlekelwa okuguquguqukayo kwama-280 bbl/hr (amagaloni angu-550 ngomzuzu, gpm) "ekulahlekelweni okuphelele." Ukwakheka kwabonakala nge-vugular porosity. Umgomo weklayenti kwakuwukupompa isisombululo se-LCM esisebenzayo ukuze sibhekane nokulahlekelwa ngokushesha ngemva kokufinyelela ekujuleni okuphelele (TD) kanye nokwenza imisebenzi yokusika izingodo ngaphandle kwesidingo sama-plug esimende, ngaleyo ndlela kongiwe isikhathi sokubhoboza. Ukwelashwa kwe-HFLS kanye ne-RFLCM kwaxutshwa emanzini, kwapompelwa nge-sub ejikelezayo, futhi kwafakwa inqubo yokucindezela okujikelezayo ngokucindezela okwanda kancane kancane. Ngemva kokucindezela, amazinga okulahlekelwa okungaguquki kanye nokuguquguquka ancishiswa abe yi-zero, okuvumela imisebenzi ukuthi iqhubeke ngokuphephile.
E-UAE, ithagethi lisebenzise kahle uketshezi lokubhoboza olungenamanzi. Ngaphansi kwezimo ezimile, ukulahlekelwa kwakusukela ku-85 kuya ku-200 bbl/hr, kuyilapho ngaphansi kwezimo eziguquguqukayo (amazinga okugeleza angu-990–1250 gpm), izinga lokulahlekelwa lalingu-150 bbl/hr. Ukwakheka kwabonakala ngokuqhekeka okuthuthukiswe ngokwemvelo. Izingxenye ze-HFLS kanye ne-RFLCM zaxutshwa ku-oyili oyisisekelo, zaphonswa nge-sub ejikelezayo, futhi zafakwa enkambisweni yokucindezelwa okujikelezayo ngokucindezela okwanda kancane kancane. Ngemva kokucindezelwa, izinga lokulahlekelwa okungaguquki lehliswa laya ku-2–15 bbl/hr, kanti izinga lokulahlekelwa okuguquguqukayo lehliswa laya ku-25 bbl/hr (lehla laya ku-5 bbl/hr ngesikhathi sokubhoboza), okuvumela imisebenzi ukuthi iqhubeke.
Ekuhlolweni kokuhlola kobuchwepheshe, ikhono lokuvala ama-fracture/vug alinganiswe elebhu anezimbobo ezifika kuma-micron angu-40,000 linikeze ukuqiniseka kokuthi inhlanganisela ye-LCM ingabhekana nobukhulu bokuqhekeka/vug obungaqinisekile. Ukusetshenziswa kwensimu okuphumelelayo kuxazulule ukulahlekelwa okukhulu kuya kokuphelele, kuqinisekisa indlela ye-HFLS/RFLCM ephindwe kabili. Inzuzo ebaluleke kakhulu yobuchwepheshe be-LCM obuthuthukisiwe ukunciphisa izindleko zokwakha imithombo ngokunciphisa isikhathi sokubhoboza esihlotshaniswa nokuphatha ukulahlekelwa okukhulu kuya kokuphelele.
Ilinganisa uhlelo lokujikeleza kwegazi olulahlekile olungenhla, inkampani yethu ithuthukise imikhiqizo emibili ngokuzimela: i-High Fluid Loss Squeeze (HFLS) agent FC-FLS kanye ne-Reticulated Foam LCM (RFLCM) agent FC-LCM, zombili ezisebenza kahle njenge-Halliburton's Foam Wedge Lost Circulation System.
