FC-634S High Temperature Fluid Loss Control Additives
• FC-634S inonzi polymer fluid loss additive ye simenti inoshandiswa muoiri tsime uye inoumbwa necopolymerization ne AMPS/NN semahombe monoma ine tembiricha yakanaka uye munyu kuramba uye pamwe chete nemamwe anti-munyu monomers.Chigadzirwa chacho chakaunza mapoka asiri nyore kuita hydrolyze kuitira kuti kupisa kwekushisa kwakanyanya kuwedzere.Mamorekuru ane huwandu hukuru hwemapoka adsorptive akadai se - CONH2, - SO3H, - COOH, iyo inoita basa rakakosha mukuramba munyu, kuramba tembiricha, kutorwa kwemvura yemahara, kuderedza kurasikirwa kwemvura, nezvimwe.
• FC-634S ine hutano hwakanaka uye inogona kushandiswa mumhando dzakasiyana-siyana dzesimende slurry systems.Iine kuwirirana kwakanaka nezvimwe zvinowedzera.
• FC-634S ine high viscosity ye low shear rate, iyo inogona kunyatso kusimudzira kugadzikana kwekumira kwe simenti slurry system, kuchengetedza fluidity ye slurry, kudzivirira sedimentation panguva imwe chete, ine yakanaka anti gas channeling performance, the viscosity ye low shear rate yakaderera pane FC-632S.
• FC-634S inokodzera tembiricha yakafara ine tembiricha yepamusoro inopikisa kusvika 230 ℃.Mushure mekushandiswa, iyo fluidity ye simenti slurry system yakanaka, yakagadzikana ine shoma yemahara mvura uye isina kudzoreredza seti uye simba rekutanga pane yakaderera tembiricha inokura nekukurumidza.Inokodzera mvura yakachena / mvura yemunyu slurry kugadzirira.
Foring Chemical FLCA inodhura yakaderera yepolymeric fluid kurasikirwa yekuwedzera yakagadzirirwa kudzikisa yakanyanya tembiricha yakanyanya kudzvanywa (HTHP) kurasikirwa kwemvura iyo inoshanda kushandiswa mumamiriro akasiyana uye zvinodiwa, senge tembiricha yakanyanya uye kuwanda kwemunyu.FC-634S yakakwira tembiricha yemvura kurasikirwa yekuwedzera yekuwedzera uye yakakodzera kumusika weRussia neNorth America.

Fluid kurasikirwa kwekudzora vamiririri vakaunzwa kune oiri-tsime simende slurries kweanopfuura makore makumi maviri, uye indasitiri yesamende yasvika pakuziva kuvandudzwa kwakanyanya mumhando yemapurojekiti esimende.Muchokwadi, zvinogamuchirwa kuti kushaikwa kwekurasikirwa kwemvura kunogona kuve mhosva yekutadza kwekutanga simende nekuda kwekuwedzera density kuwedzera kana annulus bridging, uye kuti simende yekusefa inopinda muchimiro inogona kukanganisa zvinobuda.Fluid kurasikirwa zvinowedzera zvinogona kubatsira simende slurry kupora zvakanyanya nekudzivirira kusvibiswa kwemafuta uye gasi gasi pamwe nekubudirira kudzora kurasikirwa kwemvura yesimende slurry.
