Isishwankathelo
I-OBF-VIS yenziwe ngeentlobo ngeentlobo zebiopolymers kwaye isebenzisa ubuchwepheshe bokusasazwa kobunini ukuphucula kakhulu ukusasazwa kwemveliso kunye nokuthintela "amehlo eentlanzi".Imveliso ayingcolisekanga lula ngeeyoni ezinyityilisiweyo kwaye ilungele amanzi acocekileyo, amanzi olwandle, kunye ne-brine yokomba ulwelo, ukufikelela kumaxabiso aphezulu "YP" kunye ne "LSRV".
Iimbonakalo
Zonke izinto zebhayoloji, ezingayi kubangela ingozi kumzimba womntu kunye nokusingqongileyo.
Ukumelana netyuwa elungileyo, ukonyuka okuphezulu kwe-viscosity kunye nokuphakamisa ukusikwa kwi-brine egcweleyo.
I-viscosity ephezulu yokucheba ephantsi, elawula ngokufanelekileyo ubunzulu bokungena kwe-drilling fluid filtrate ekubunjweni kwaye ikhusela i-oyile kunye ne-gas reservoirs.
Ukwenziwa kwejeli ekufutshane ne-static kufuphi nodonga lomthombo kuthintela ukubunjwa kwe "chip bed", ekulungele ngokukodwa ukugrumba amaqula anqamlekileyo kunye ne-slope enkulu kunye nokufuduka okukhulu.
Umphumo we-synergistic phakathi kwezinto uphucula ukuchasana kobushushu bezinto eziphilayo kwaye ufanelekile ukubhobhoza kwiifom ezinobushushu be-120 ° C.
Idatha yobugcisa
| Into | I-viscosity yeplastiki (mPa·s) | Amandla okusika anamandla (Pa) | φ3/φ6 | I-LSVR (mPa·s) | |
| Amanzi amatsha, amanzi anetyuwa kunye namanzi endalo olwandle +0.8％OBF-VIS | Ubushushu obuqhelekileyo | ≥15 | ≥15 | ≥10/12 | ≥50000 |
| 120℃ I-Hot roll 16h | ≥9 | ≥7 | ≥6/8 | ≥30000 | |
Uluhlu losetyenziso
Ubushushu besicelo: ≤120℃(BHCT)
Ncoma idosi (BWOC): 0.5-1.0 %
Iphakheji
Ipakishwe i-25kg yengxowa yephepha eninzi enefilim yeplastiki engenamanzi ngaphakathi.Okanye ngokusekelwe kwisicelo sabathengi.
Ubomi beshelufu: iinyanga ezingama-24.
