FC-FR220S Ilahleko yolwelo izongezo zoLawulo
I-fluid loss control sulphonate copolymer (i-drilling fluid) i-FC-FR220S ithatha ingcamango yoyilo lwesakhiwo se-molecular ukuphucula ukuqina kwe-molecule ye-copolymer.Iyunithi yokuphinda i-monomer yaziswa inomthamo omkhulu wendawo, enokunyusa ngokufanelekileyo isithintelo se-steric kunye nokuphucula umphumo wemveliso ekulawuleni ilahleko ye-HTHP yamanzi;Kwangaxeshanye, ukukwazi kwayo ukumelana nobushushu kunye netyuwa ye-calcium iphuculwa ngakumbi ngokulungiswa kobushushu kunye neemonomers ezinyamezela ityuwa.Le mveliso yoyisa iziphene zolawulo lokulahleka kolwelo lwepolymer oluqhelekileyo, olufana nokunganyangeki kakuhle kwe-chear, ukunganyangeki kwekhalsiyam yetyuwa, kunye nesiphumo esingonelisiyo sokulawula ukulahleka kolwelo lwe-HTHP.Lulawulo olutsha lwe-polymer fluid.

1. I-FC-FR220S inamandla okuxhathisa ityuwa.Ngokusebenzisa iimvavanyo zangaphakathi, lungisa umxholo wetyuwa wenkqubo ye-drilling fluid esetyenziselwa ukuvavanya ukuphanda ukuxhathisa ityuwa ye-FC-FR220S yemveliso emva kokuguga kwi-200 ℃ kudaka olusisiseko olunomxholo ohlukeneyo wetyuwa.Iziphumo zovavanyo ziboniswe kuMfanekiso 1:
Phawula: Ukubunjwa kwesiseko se-slurry yokuvavanya: 6% w / v umhlaba we-sodium + 4% w / v wokuvavanya umhlaba + 1.5% v / v isisombululo se-alkali (40% yoxinaniso);
Ilahleko yolwelo lwe-HTHP iya kuvavanywa kwi-150℃ kwi-3.5MPa.
Inokubonwa kwiziphumo zovavanyo kwi-Figure 1 ukuba i-FC-FR220S inomsebenzi ogqwesileyo ekulawuleni ilahleko ye-HTHP yamanzi phantsi kwezinto ezahlukeneyo zetyuwa, kwaye inomsebenzi ozinzile kunye nokuxhathisa ityuwa.
2. I-FC-FR220S inozinzo oluhle kakhulu lwe-thermal.Uvavanyo lwangaphakathi lwenziwa ukuphanda umda wokuxhathisa ubushushu bemveliso ye-FC-FR220S kwi-30% ye-brine slurry ngokunyusa ngokuthe ngcembe iqondo lobushushu le-FC-FR220S.Iziphumo zovavanyo ziboniswe kuMfanekiso 2:
Phawula: Ilahleko ye-HTHP yolwelo ivavanywa kwi-150 ℃ kunye ne-3.5MPa.
Inokubonwa kwiziphumo zovavanyo kuMfanekiso 2 ukuba iFC-FR220S isenendima entle ekulawuleni ilahleko ye-HTHP yolwelo kwi-220 ℃ ngokunyuka kwamaqondo obushushu, kwaye inokumelana nobushushu obugqwesileyo kwaye ingasetyenziselwa iqula elinzulu kunye ne-ultra deep well. ukugrumba.Idatha yovavanyo iphinda ibonise ukuba i-FC-FR220S inomngcipheko we-desorption ephezulu yeqondo lokushisa kwi-240 ℃, ngoko ke akukhuthazwa ukuyisebenzisa kule bushushu okanye ngaphezulu.
3. I-FC-FR220S inokuhambelana kakuhle.Ukusebenza kwe-FC-FR220S emva kokuguga kwi-200℃ kumanzi olwandle, i-compound brine kunye ne-saturated brine drilling fluid systems iyaphandwa ngeemvavanyo zaselabhorethri.Iziphumo zovavanyo ziboniswe kwiThebhile 2:
Itheyibhile yesi-2 yoVavanyo loMsebenzi weZiphumo ze-FC-FR220S kwiiNkqubo eziDidifferent Drilling Fluid
| Into | AV mPa.s | FL API ml | FL HTHP ml | Phawula |
| Ulwelo lokwemba amanzi olwandle | 59 | 4.0 | 12.4 | |
| I-Compound brine yokomba ulwelo | 38 | 4.8 | 24 | |
| Ulwelo lokugrumba i-brine egcweleyo | 28 | 3.8 | 22 |
Inokubonwa kwiziphumo zovavanyo kwiThebhile 2 ukuba i-FC-FR220S inokuhambelana kakuhle kwaye lulawulo olubalaseleyo lwelahleko yolwelo lokulawula ukulahleka kolwelo lweHTHP lweenkqubo zokomba zokomba ezifana namanzi olwandle, i-compound brine kunye ne-saturated brine, njl.
