Isishwankathelo
I-OBF-FLC22 ithatha ingqikelelo yoyilo lwemolekyuli yokuphucula ukuqina kweemolekyuli ze-copolymer, kwaye iyunithi yokuphinda ye-monomer yaziswa inomthamo omkhulu wendawo, enokwandisa ngokufanelekileyo umqobo we-steric kunye nokuphucula isiphumo sokunciphisa ilahleko yokucoca i-HTHP yemveliso.Kwangaxeshanye, ngokukhethwa kwemonoma yobushushu kunye netyuwa enganyangekiyo, amandla obushushu kunye netyuwa enganyangekiyo nge-calcium yandiswa ngakumbi.Imveliso yoyisa iziphene zesinciphisi sokulahleka kolwelo lwepolymer oluqhelekileyo, olufana nokunganyangeki kakuhle kwe-chear, ukunganyangeki kwe-calcium yetyuwa kunye nesiphumo esinganelisiyo sokunciphisa ilahleko ye-HTHP.Yinto entsha yokunciphisa ilahleko ye-polymer fluid.

Iimbonakalo
I-OBF-FLC22 inamandla okuxhathisa ityuwa.Ngokusebenzisa iimvavanyo zaselabhoratri, umxholo wetyuwa wenkqubo ye-drilling fluid esetyenziselwa ukuvavanya wahlengahlengiswa, kwaye ukuxhathisa kwetyuwa ye-OBF-FLC22 imveliso yaphandwa emva kokuguga kwi-200 ℃ kwisiseko se-slurry esinomxholo ohlukeneyo wetyuwa.
I-OBF-FLC22 inozinzo oluhle kakhulu lwe-thermal.Kuvavanyo lwaselabhoratri, ubushushu bokuguga be-OBF-FLC22 bonyuswa kancinci kancinci ukuze kuphandwe umda wokuxhathisa ubushushu beemveliso ze-OBF-FLC22 kwi-30% yodaka lwetyuwa.
I-OBF-FLC22 inokuhambelana kakuhle.Ukusebenza kwe-OBF-FLC22 eneminyaka engama-200 ℃ kumanzi olwandle, ityuwa ehlanganisiweyo kunye neenkqubo zolwelo zokwembiwa kwe-saturated saline yaphandwa ngovavanyo lwaselabhoratri.
| 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 |
