FC-FR220S Izithasiselo zokulawula ukulahleka koketshezi
Ukulawulwa kokulahlekelwa uketshezi lwe-sulphonate copolymer (uketshezi lokubhoboza) i-FC-FR220S yamukela umqondo womklamo wesakhiwo samangqamuzana ukuze kuthuthukiswe ukuqina kwe-molecule ye-copolymer.Iyunithi yokuphinda ye-monomer eyethulwe inevolumu yesikhala esikhulu, engakhuphula ngempumelelo isithiyo esibulalayo futhi ithuthukise umphumela womkhiqizo ekulawuleni ukulahlekelwa uketshezi lwe-HTHP;Ngesikhathi esifanayo, ikhono layo lokumelana nezinga lokushisa kanye ne-calcium kasawoti lithuthukiswa ngokwengeziwe ngokulungiswa kwezinga lokushisa kanye nama-monomers abekezelela usawoti.Lo mkhiqizo unqoba ukushiyeka kokulawulwa okujwayelekile koketshezi lwe-polymer, njengokungazweli kahle kwe-shear, ukumelana ne-calcium kasawoti okungekuhle, kanye nomthelela ongagculisi wokulawula ukulahleka koketshezi lwe-HTHP.Isilawuli esisha sokulahlekelwa uketshezi lwe-polymer.

1. I-FC-FR220S inokumelana nosawoti okuqinile.Ngokuhlolwa kwangaphakathi, lungisa okuqukethwe kukasawoti wesistimu yoketshezi lokumba olusetshenziselwa ukuhlola ukuze kuphenywe ukumelana kukasawoti womkhiqizo we-FC-FR220S ngemva kokuguga ku-200 ℃ odakeni oluyisisekelo olunosawoti ohlukile.Imiphumela yokuhlolwa iboniswa kuMfanekiso 1:
Phawula: Ukwakhiwa kwe-base slurry ukuze kuhlolwe: 6% w/v inhlabathi yesodium+4% w/v yokuhlola inhlabathi+1.5% v/v isixazululo se-alkali (40% ukugxila);
Ukulahlekelwa uketshezi lwe-HTHP kuzohlolwa ku-150℃ ku-3.5MPa.
Kungabonakala emiphumeleni yokuhlola kuMfanekiso 1 ukuthi i-FC-FR220S inokusebenza okuhle kakhulu ekulawuleni ukulahlekelwa uketshezi lwe-HTHP ngaphansi kokuqukethwe okuhlukile kukasawoti, futhi inokusebenza okuzinzile kanye nokumelana nosawoti okuhle kakhulu.
2. I-FC-FR220S inokusimama okuhle kakhulu kwe-thermal.Ukuhlolwa kwangaphakathi kwenziwa ukuze kuphenywe umkhawulo wokumelana nezinga lokushisa lomkhiqizo we-FC-FR220S ku-30% we-brine slurry ngokukhuphula kancane kancane izinga lokushisa lokuguga le-FC-FR220S.Imiphumela yokuhlolwa iboniswa kuMfanekiso 2:
Phawula: Ukulahlekelwa uketshezi lwe-HTHP kuhlolwa ku-150 ℃ naku-3.5MPa.
Kungabonakala emiphumeleni yokuhlola kuMfanekiso 2 ukuthi i-FC-FR220S isenendima enhle ekulawuleni ukulahlekelwa uketshezi lwe-HTHP ku-220℃ ngokukhuphuka kwezinga lokushisa, futhi inokumelana nezinga lokushisa okuhle kakhulu futhi ingasetshenziselwa umthombo ojulile kanye nomthombo ojulile kakhulu. ukubhoboza.Idatha yokuhlola iphinda ibonise ukuthi i-FC-FR220S inengcuphe ye-desorption ephezulu yezinga lokushisa elingu-240℃, ngakho-ke ayinconyiwe ukuyisebenzisa kuleli zinga lokushisa noma ngaphezulu.
3. I-FC-FR220S inokuhambisana okuhle.Ukusebenza kwe-FC-FR220S ngemva kokuguga ku-200℃ emanzini olwandle, amanzi axutshwe ne-brine kanye nezinhlelo zoketshezi zokumba amanzi agcwele amanzi kuyaphenywa ngokuhlolwa kwaselabhorethri.Imiphumela yokuhlolwa ikhonjiswe kuThebula 2:
Ithebula 2 Lokuhlola Ukusebenza Kwemiphumela ye-FC-FR220S Ezinhlelweni Ezihlukene Zokubhoboza Uketshezi
| Into | I-AV mPa.s | I-FL API ml | FL HTHP ml | Phawula |
| Uketshezi lokumba amanzi olwandle | 59 | 4.0 | 12.4 | |
| Uketshezi lokumba lwe-brine oluhlanganisiwe | 38 | 4.8 | 24 | |
| I-saturated brine drilling fluid | 28 | 3.8 | 22 |
Kungabonakala emiphumeleni yokuhlola kuThebula 2 ukuthi i-FC-FR220S inokusebenzisana okuhle futhi iwukulawula okuhle kakhulu kokulahlekelwa uketshezi lokulawula ukulahlekelwa koketshezi lwe-HTHP lwamasistimu oketshezi okumba njengamanzi olwandle, i-compound brine kanye ne-saturated brine, njll.
