Ukulawulwa kokulahlekelwa uketshezi kwe-FC-FR180S
I-copolymer ye-sulphonate yokulawula ukulahlekelwa uketshezi (uketshezi lokubhoboza) i-FC-FR180S yakhiwa nge-polymerization yezinyathelo eziningi ngaphansi kwesenzo sokuqalisa yi-acrylic amide, i-acrylic acid, i-2-acryloyloxybutyl sulfonic acid (AOBS), i-epoxy chloropropane kanye ne-new ring structure cationic monomer. Lo mkhiqizo uwukulawula ukulahlekelwa uketshezi olumelana nokushisa okuphezulu kanye nokumelana nosawoti kanye nokusebenza okuhle kokunciphisa ukulahlekelwa uketshezi. Unomphumela omuhle wokwandisa i-viscosity ku-slurry yamanzi ahlanzekile, futhi ukhulisa kancane i-viscosity ku-slurry yamanzi anosawoti futhi ungasetshenziswa njenge-ejenti yokwandisa i-viscosity kanye nokulawula ukulahlekelwa uketshezi ku-solid free and low solid drilling fluids. Lo mkhiqizo unokumelana okuhle nokushisa kanye nokumelana nosawoti, ukumelana nokushisa kungafinyelela ku-180℃, futhi ukumelana nosawoti kungafinyelela ekugcwaleni. Ufaneleka kakhulu ku-sea water drilling fluid, uketshezi lokubhoboza olujulile kanye noketshezi lokubhoboza olujulile kakhulu.

| Ukulahleka koketshezi lwe-API kwe-4% brine slurry ngemva kokugoqa okushisayo ku-160℃, mL | ≤12.0 |
1. Umphumela ophezulu, umthamo ophansi, umsebenzi omuhle wokulawula ukulahleka koketshezi.
2. Inokuqina okuhle kokushisa kanye nokumelana nokushisa okungu-180℃, futhi ingasetshenziswa emithonjeni ejulile nejulile kakhulu;
3. Inokumelana okunamandla nosawoti ekugcwaleni kanye nokumelana ne-calcium magnesium, futhi ingasetshenziswa ekubholeni nasekuqedeni uketshezi emanzini ahlanzekile, emanzini anosawoti, emanzini anosawoti agcwele kanye namanzi olwandle;
4. Inomphumela omuhle wokwandisa ukujiya emanzini ahlanzekile.
