Abstract
Iimeko zangoku zexabiso le-oyile eliphantsi lihlaziye ugxininiso lokugrumba ukuze kugcinwe ixesha lokugrumba ioli kunye negesi kunye nokunciphisa iindleko zokusebenza.Ireyithi yokungena (i-ROP) imodeli sisixhobo esiphambili ekuphuculeni iiparamitha zokomba, ezizezi, ubunzima bebit kunye nesantya esijikelezayo kwiinkqubo zokomba ezikhawulezayo.Ngenoveli, yonke i-automated data visualization kunye ne-ROP modeling tool ephuhliswe kwi-Excel VBA, i-ROPPlotter, lo msebenzi uphanda ukusebenza kwemodeli kunye nefuthe lamandla elitye kwi-coefficients yemodeli ye-PDC Bit ye-ROP ezimbini ezahlukeneyo: i-Hareland ne-Rampersad (1994) kunye ne-Motahhari. okqhubekayo.(2010).Ezi zimbini PDC bit iimodeli zithelekiswa kwimeko yesiseko, ubudlelwane be-ROP ngokubanzi buphuhliswe nguBingham (1964) kwiindlela ezintathu ezahlukeneyo zelitye lentlabathi kwicandelo elithe nkqo le-Bakken shale ethe tye.Okokuqala, umzamo wenziwa wokwahlula isiphumo soguqulo lwamandla amatye kwimodeli ye-ROP coefficients ngokuphanda i-lithologies ngezinye iiparamitha zokomba ezifanayo.Ukongezelela, ingxoxo ebanzi ngokubaluleka kokukhetha imodeli efanelekileyo yemida ye-coefficients iqhutywa.Amandla e-rock, abalwe kwiimodeli ze-Hareland kunye ne-Motahhari kodwa kungekhona kwi-Bingham's, kukhokelela kumaxabiso aphezulu ophindaphindayo obuninzi beemodeli zemodeli zangaphambili, ukongeza kwi-RPM yexesha elikhulayo le-exponent yemodeli ye-Motahhari.Imodeli ye-Hareland kunye ne-Rampersad iboniswa iqhuba kakuhle kwiimodeli ezintathu ezinale datha yedatha.Ukusebenza kunye nokusetyenziswa komfuziselo we-ROP yemveli kubuzwa, njengoko imifuziselo enjalo ixhomekeke kwiseti ye-empirical coefficients ebandakanya isiphumo sezinto ezininzi zokomba ezingabalelwanga ekuqulunqweni kwemodeli kwaye zikhethekile kwi-lithology ethile.
Intshayelelo
Amasuntswana e-PDC (i-Polycrystalline Diamond Compact) lolona hlobo lubalaseleyo olusetyenziswa ekugrumbeni i-oyile kunye nemithombo yerhasi namhlanje.Ukusebenza kwesuntswana ngokuqhelekileyo kulinganiswa ngomlinganiselo wokungena (ROP), isalathiso sokukhawuleza kwequla eligrunjwayo ngokobude bomngxuma ogrunjwayo ngexesha leyunithi.Ukugrumba kakuhle bekuphambili kwii-ajenda zeenkampani zamandla amashumi eminyaka ngoku, kwaye kuzuza ukubaluleka ngakumbi ngexesha lemeko yexabiso le-oli ekhoyo ngoku (eHareland naseRampersad, 1994).Inyathelo lokuqala ekuphuculeni iiparamitha zokomba ukuvelisa eyona ROP inokubakho kuphuhliso lwemodeli echanekileyo enxulumene nemilinganiselo efunyenwe kumphezulu ukuya kwinqanaba lokomba.
Iimodeli ezininzi ze-ROP, kubandakanywa iimodeli eziphuhliswe ngokukodwa uhlobo oluthile oluthile, zipapashiwe kuncwadi.Le mifuziselo ye-ROP idla ngokuqulatha inani lee-empirical coefficients ezixhomekeke kwi-lithology kwaye zinokuphazamisa ukuqonda kobudlelwane phakathi kweeparamitha zokomba kunye nesantya sokungena.Injongo yolu phononongo kukuhlalutya imodeli yokusebenza kunye nendlela ii-coefficients zemodeli eziphendula ngayo kwidatha yendawo kunye neeparamitha zokomba ezohlukeneyo, ngakumbi amandla amatye, amabini.PDC bit iimodeli (iHareland kunye neRampersad, 1994, Motahhari et al., 2010).Imodeli ye-coefficients kunye nokusebenza kwakhona kuthelekiswa nesiseko se-ROP imodeli (Bingham, 1964), ubudlelwane obulula obusebenza njengemodeli yokuqala ye-ROP esetyenziswa ngokubanzi kulo lonke ishishini kwaye isasetyenziswa ngoku.Ukugrumba idatha kwimizobo emithathu yelitye lentlabathi enamandla okwahluka-hlukeneyo yamatye kuyaphandwa, kwaye imodeli yomlinganiso womlinganiso wale mifuziselo mithathu iyabalwa kwaye ithelekiswe ngokuchasene nenye.Kuqikelelwa ukuba i-coefficients yeemodeli ze-Hareland kunye ne-Motahhari kulwakhiwo ngalunye lwamatye luya kubala uluhlu olubanzi kune-coefficients yomzekelo we-Bingham, njengoko amandla amatye ahlukeneyo angabalwa ngokucacileyo kuqulunqo lwamva.Ukusebenza komzekelo kukwavavanyiwe, okukhokelela ekukhetheni eyona modeli ingcono yeROP yengingqi yaseBakken shale eMntla Dakota.
Iimodeli ze-ROP ezibandakanyiweyo kulo msebenzi ziquka i-equations engaguqukiyo ehambelana neeparameters ezimbalwa zokomba kunye nesantya sokomba kwaye iqulethe isethi ye-coefficients yamandla edibanisa impembelelo yeendlela zokomba ezinzima, ezifana ne-hydraulics, i-cutter-rock interaction, bit. uyilo, iimpawu zendibano yomngxuma ongezantsi, uhlobo lodaka, kunye nokucoca umngxuma.Nangona ezi modeli zeROP zemveli zingasebenzi kakuhle xa zithelekiswa nedatha yendawo, zibonelela ngelitye elibalulekileyo lokunyathela kubuchule obutsha bokubumba.Iimodeli zanamhlanje, ezinamandla ngakumbi, ezisekelwe kumanani kunye nokunyuka kokuguquguquka kunokuphucula ukuchaneka kwe-ROP modeling.I-Gandelman (2012) inike ingxelo yophuculo olubalulekileyo kwimodeli ye-ROP ngokusebenzisa uthungelwano lwe-neural eyenziweyo endaweni yeemodeli ze-ROP zemveli kumaqula e-oyile kwizitya zangaphambili zetyuwa kude nonxweme lwaseBrazil.Uthungelwano lwe-neural eyenziweyo lukwasetyenziswa ngempumelelo ukuqikelela iROP kwimisebenzi kaBilgesu et al.(1997), uMoran et al.(2010) kunye no-Esmaeili et al.(2012).Nangona kunjalo, ukuphuculwa okunjalo kwimodeli ye-ROP kuza kwindleko yokutolika imodeli.Ngoko ke, iimodeli ze-ROP zendabuko zisafanelekile kwaye zibonelela ngendlela esebenzayo yokuhlalutya indlela iparameter ethile yokumba ichaphazela izinga lokungena.
I-ROPPlotter, i-data visualization ye-field data kunye ne-ROP modeling software eyenziwe kwi-Microsoft Excel VBA (i-Soares, i-2015), iqeshwe ekubaleni i-coefficients yemodeli kunye nokuthelekisa ukusebenza kwemodeli.
