Kungani I-Dissolvable Frac Plugs Iba Ibalulekile?

Amapulaki e-frac ancibilikayo, naphezu kwezinzuzo zawo ezingaba khona ekusebenzeni kahle nokonga kwezindleko, okwamanje abambe ngaphansi kuka-20% wesabelo semakethe endleleni yokuqedela ipulaki ne-perf. Izithiyo ezivame ukucashunwa zihlanganisa ukuguguleka kwe-casing kanye nezilinganiso zokuhlakazeka ezingalindelekile, okuholela ekukhuphukeni kwezindleko kanye nezikhathi zokuqeda isikhathi eside. Kodwa-ke, ukuthuthuka kwemiklamo eyenziwe lula ye-frac plug ihlose ukunciphisa lezi zinselele futhi kuthuthukise ukusebenza kahle, ikakhulukazi emidlalweni emikhulu engajwayelekile emhlabeni jikelele.

Omunye umkhawulo obalulekile wamapulagi endabuko e-frac usekusetshenzisweni kwama-elastomer. Nakuba ama-elastomer esetshenziselwe kabanzi ukuhlukaniswa kwendawo kuwo womabili amapulagi e-frac ayinhlanganisela nahlukaniseka, ajwayele ukwehluleka ngaphansi kwezimo zokushisa eziphezulu nezinga lokushisa, okuholela ekugugulekeni nasekugugulekeni kwe-casing. Izindlela zokulwa nokukhishwa kwe-anti-extrusion, ezifana namapuleti agqagqene noma izindandatho, zifakwe kumiklamo esekelwe ku-elastomer ukuvimbela ukukhishwa. Kodwa-ke, lezi zindlela zingase zehluleke noma zingasebenzisi ngokugcwele ezimweni eziyinkimbinkimbi zemigodi, zibeke engcupheni ubuqotho bokuzihlukanisa.

Ukubhekana nalezi zinkinga, ama-metal-seal dissolvable frac plug avele njengenye isixazululo. Ngokusebenzisa i-metal-to-metal seal, lawa mapulaki ahlinzeka ngokuhlukaniswa okuthembekile ngaphandle kwesidingo sezinqubo eziyinkimbinkimbi zokulwa ne-extrusion. Lokhu kwenza ukwakheka kwepulaki kube lula, kunciphisa inani lezingxenye, futhi kuthuthukise ukusebenza kahle kokuhlanza. Ukwengeza, izigxivizo zensimbi zisusa izingozi ezihamba ngesivinini esiphezulu se-annular, zithuthukisa ukuphepha kokusebenza.

Ezimweni eziyinselele, izigxivizo ezihlanganisiwe ezihlanganisa izindandatho ze-elastomer nezindlela zensimbi-seal zinikeza isisombululo esisebenzayo. I-elastomer ekuqaleni isebenza njengesithiyo sokucindezela ngesikhathi sokuvuselela, kuyilapho uphawu lwensimbi lusebenzisana nodonga lwe-casing ngaphansi kwengcindezi eyandayo, iqinisekisa ukuhlukaniswa okuqinile kanye nezakhiwo zokulwa nokukhishwa.

Ngokuphambene, amapulagi e-frac ancibilikayo endabuko ngokuvamile ahlanganisa izingxenye eziyinkimbinkimbi ezisengozini yokuhluleka, ikakhulukazi ngaphansi kwezimo zokushisa nezimo zengcindezi. Ukwengeza, izilinganiso zabo zokuchithwa ezenziwe ngokwezifiso zingaba inselele ukubikezela nokulawula, zikhawulele ukuhlukahluka kwazo kuzo zonke izindawo zemithombo ehlukene kanye nezimo zokukhiqiza.

Ukuze unqobe lezi zinselele, ukucatshangelwa okuphelele kwezidingo eziqondene nohlelo lokusebenza kanye nezimiso zobunjiniyela kubalulekile ekuklameni amapulaki ahlakazekayo. Abahlinzeki bamathuluzi kufanele bahlaziye ngokucophelela imininingwane yokusebenza, balingise izimo ze-downhole, futhi bathuthukise ukusebenza kwepulaki ukuze bathole imiphumela efiselekayo. Ukuthola ibhalansi phakathi kokuthembeka kwamathuluzi nezici zokuhlakazeka kubalulekile empumelelweni kuzo zonke izinhlelo zokusebenza nezindawo ezahlukahlukene.

Sengiphetha, nakuba ama-frac plugs angancibilika enikeza izinzuzo ezibalulekile ezingaba khona, ukuqaliswa kwawo ngempumelelo kuncike ekubhekaneni nemikhawulo eyinhloko ngokusebenzisa idizayini emisha, ubunjiniyela obuqinile, kanye nokuhlela okuphelele kokusebenza. Ngokusebenzisa ubuchwepheshe obuthuthukisiwe nezisombululo ezihambisanayo, imboni ingavula amandla aphelele ama-frac plugs ancibilikayo ekuthuthukiseni ukusebenza kahle kokuqedwa nokusebenza kahle.

Ipulaki ye-frac encibilikayo evela ku-Vigor ingenziwa ngokwezifiso ngokuvumelana nezidingo zekhasimende, futhi ingancibilika ngokuphelele ngo-100%, uma unesithakazelo emikhiqizweni yethu yochungechunge lwamapulaki ebhuloho, sicela ungangabazi ukuthintana nathi.
