E faʻafefea ona iloa le iloiloga o PDC bit ROP faʻataʻitaʻiga ma le aʻafiaga o le malosi papa i luga o faʻataʻitaʻiga coefficients?

Pu'upu'u

Ole tau maualalo ole suau'u ile taimi nei ua toe fa'afou ai le fa'amamafaina ole viliina lelei ina ia sefe ai le taimi e viliina ai le suau'u ma kesi vaieli ma fa'aitiitia ai tau o galuega.Fa'ata'ita'iga o le fua o le penetration (ROP) ose meafaigaluega autu i le fa'asilisiliina o fa'amaufa'ailoga viliina, e ta'ua o le mamafa o le pa'u ma le saoasaoa fa'ata'amilo mo fa'agaoioiga vili vave.Faʻatasi ai ma se tala, faʻamatalaga faʻamatalaga faʻapitoa uma ma meafaigaluega faʻataʻitaʻiga ROP na fausia i Excel VBA, ROPPlotter, o lenei galuega e suʻesuʻeina faʻataʻitaʻiga faʻataʻitaʻiga ma le aʻafiaga o le malosi papa i luga o faʻataʻitaʻiga faʻataʻitaʻiga o faʻataʻitaʻiga PDC Bit ROP eseese e lua: Hareland ma Rampersad (1994) ma Motahhari ma isi.(2010).O nei mea e lua PDC bit fa'ata'ita'iga fa'atusa e fa'atatau i se mataupu fa'avae, fa'alapotopotoga lautele ROP na atia'e e Bingham (1964) i ni ma'a oneone eseese se tolu i le vaega tu'usa'o o se va'a fa'alava Bakken shale.Mo le taimi muamua, ua faia se taumafaiga e fa'aesea le a'afiaga o le malosi o papa i luga o fa'ata'ita'iga ROP coefficients e ala i le su'esu'eina o lithologies fa'atasi ai ma isi mea fa'atusa e viliina.E le gata i lea, o se talanoaga atoatoa i le taua o le filifilia o tuaoi faʻataʻitaʻiga talafeagai e faʻatautaia.O le malosi o papa, e fa'atatau i fa'ata'ita'iga a Hareland ma Motahhari ae le o Bingham's, e maua ai le maualuga o tau o fa'atusa fa'atele faifaipea mo fa'ata'ita'iga muamua, fa'aopoopo i le fa'atuputeleina o le fa'aupuga o le RPM mo le fa'ata'ita'iga a Motahhari.O le faʻataʻitaʻiga a Hareland ma Rampersad o loʻo faʻaalia e sili ona lelei mai faʻataʻitaʻiga e tolu ma lenei faʻamaumauga faʻapitoa.O le aoga ma le faʻaogaina o faʻataʻitaʻiga masani a le ROP ua fesiligia, ona o ia faʻataʻitaʻiga e faʻalagolago i se seti o faʻatusatusaga faʻapitoa e aofia ai le aʻafiaga o le tele o mea e viliina e le o faʻamatalaina i le faʻatulagaina o le faʻataʻitaʻiga ma e tulaga ese i se lithology faapitoa.

Folasaga

O fasi PDC (Polycrystalline Diamond Compact) o le ituaiga sili lea e fa'aaogaina i le suau'u ma le kesi vaieli i aso nei.Ole fa'atinoga ole bit e masani ona fua ile fua ole penetration (ROP), o se fa'aaliga o le vave e viliina ai le vaieli pe a fua ile umi ole pu e viliina ile iunite taimi.O le fa'ata'ita'iina o le viliina o lo'o ta'imua i fuafuaga a kamupani malosi mo le tele o tausaga i le taimi nei, ma o lo'o fa'ateleina le taua i le tau maualalo o le suau'u (Hareland ma Rampersad, 1994).O le la'asaga muamua i le fa'asilisiliina o tapula'a e viliina ina ia maua ai le ROP sili ona lelei o le fa'atupuina lea o se fa'ata'ita'iga sa'o e fa'atatau i fua fa'atatau e maua i luga ole fua ole viliina.

E tele fa'ata'ita'iga a le ROP, e aofia ai fa'ata'ita'iga na fa'atupuina fa'apitoa mo se ituaiga vaega, ua fa'asalalauina i tusitusiga.O nei fa'ata'ita'iga ROP e masani lava ona i ai le tele o fa'amaufa'ailoga fa'apitoa e fa'alagolago i le lithology ma e ono fa'aleagaina ai le malamalama i le va o ta'aloga vili ma le fua o le ulu.O le fa'amoemoega o lenei su'esu'ega o le su'esu'eina lea o le fa'atinoga o fa'ata'ita'iga ma pe fa'afefea ona tali atu fa'ata'ita'i fa'ata'ita'iga i fa'amaumauga o fanua ma fa'asologa eseese o le viliina, aemaise le malosi o papa, mo le lua.PDC bit faʻataʻitaʻiga (Hareland ma Rampersad, 1994, Motahhari et al., 2010).O fa'ata'ita'iga fa'atusa ma fa'atinoga e fa'atusaina fo'i i se fa'ata'ita'iga ROP fa'avae (Bingham, 1964), o se fa'aoga faigofie na avea ma fa'ata'ita'iga muamua ROP fa'aoga lautele i totonu o alamanuia ma o lo'o fa'aogaina pea.E su'esu'eina le su'eina o fa'amaumauga o fanua i ma'a oneone e tolu ma le malosi o ma'a eseese, ma fa'atusatusa fa'atusa mo nei fa'ata'ita'iga e tolu ma fa'atusatusa le tasi i le isi.O lo'o fa'apea o fa'atusatusaga mo fa'ata'ita'iga a Hareland ma Motahhari i fa'avae papa ta'itasi o le a lautele atu nai lo fa'ata'ita'iga fa'ata'ita'i a Bingham, ona e le o fa'ailoa manino mai i le fa'asologa mulimuli.O faʻataʻitaʻiga faʻataʻitaʻiga o loʻo iloiloina foi, e taʻitaʻia ai le filifiliga o le ROP sili ona lelei mo le Bakken shale region i North Dakota.

O faʻataʻitaʻiga ROP o loʻo aofia ai i lenei galuega e aofia ai faʻataʻitaʻiga e le mafai ona faʻaogaina e fesoʻotaʻi ai ni nai faʻamaufaʻailoga viliina i le fua o le viliina ma o loʻo i ai se seti o faʻamalosi faʻamalosi e tuʻufaʻatasia ai le aʻafiaga o faiga faʻataʻitaʻiga faigata, e pei o hydraulics, cutter-rock interaction, bit. mamanu, uiga potopotoga pito i lalo-pu, ituaiga palapala, ma le faamamaina o pu.E ui lava o nei fa'ata'ita'iga masani ROP e masani ona le lelei pe a fa'atusatusa i fa'amaumauga o fanua, latou te maua ai se la'a taua i faiga fa'atusa fou.O faʻataʻitaʻiga faʻaonaponei, sili atu ona mamana, faʻavae faʻamaumauga faʻatasi ma faʻateleina fetuutuunai e mafai ona faʻaleleia le saʻo o le ROP faʻataʻitaʻiga.Gandelman (2012) ua lipotia mai le faʻaleleia atili o le ROP faʻataʻitaʻiga e ala i le faʻaogaina o fesoʻotaʻiga neural faʻapitoa nai lo faʻataʻitaʻiga ROP masani i vaieli suauʻu i totonu o pesini masima i fafo atu o Pasila.O feso'ota'iga neural fa'akomepiuta o lo'o fa'aogaina lelei fo'i mo valo'aga a le ROP i galuega a Bilgesu et al.(1997), Moran et al.(2010) ma Esmaeili et al.(2012).Ae ui i lea, o le faʻaleleia atili o le ROP faʻataʻitaʻiga e sau i le faʻaaluina o faʻataʻitaʻiga faʻamatalaina.O le mea lea, o fa'ata'ita'iga ROP fa'aleaganu'u o lo'o talafeagai pea ma tu'uina atu se auala lelei e iloilo ai pe fa'afefea ona a'afia le fua o le fa'aosoina e se vaega vili fa'apitoa.

ROPPlotter, o se fanua faʻamatalaga faʻamatalaga ma ROP faʻataʻitaʻiga polokalama faʻapipiʻi i le Microsoft Excel VBA (Soares, 2015), o loʻo faʻafaigaluegaina i le faʻatusatusaina o faʻataʻitaʻiga faʻataʻitaʻiga ma faʻatusatusa le faʻatinoga o faʻataʻitaʻiga.
