FC-FR220S Fluid kurasikirwa Kudzora zvinowedzera
Iyo fluid kurasikirwa inodzora sulphonate copolymer (drilling fluid) FC-FR220S inotora pfungwa yemamorekuru chimiro dhizaini kuvandudza kuoma kweiyo copolymer molecule.Iyo yakaunzwa monomer inodzokorora unit ine yakakura nzvimbo vhoriyamu, iyo inogona zvinobudirira kuwedzera steric chipingamupinyi uye kugadzirisa mhedzisiro yechigadzirwa pakudzora HTHP kurasikirwa kwemvura;Panguva imwecheteyo, kugona kwayo kuramba tembiricha uye munyu calcium inowedzerwa kuburikidza nekugadzirisa tembiricha uye munyu inoshivirira monomers.Ichi chigadzirwa chinokunda zvikanganiso zvezvakajairwa polymer fluid kurasikirwa kwekudzora, senge kusakara kushera, kushomeka kwemunyu karusiyamu kuramba, uye isingagutsi mhedzisiro yekudzora kurasikirwa kweHTHP.Iyo itsva polymer fluid kurasikirwa kutonga.

1. FC-FR220S ine munyu wakasimba.Kuburikidza nemiedzo yemukati, gadzirisa munyu weiyo yekuchera fluid sisitimu inoshandiswa pakuongorora kuongorora munyu kuramba kweFC-FR220S chigadzirwa mushure mekuchembera pa200 ℃ mudhaka repasi rine munyu wakasiyana.Mibairo yekuedza inoratidzwa muFigure 1:
Remark: Kuumbwa kwebase slurry yekuongorora: 6% w / v sodium ivhu + 4% w / v kuongorora ivhu + 1.5% v / v alkali solution (40% concentration);
HTHP kurasikirwa kwemvura kuchaedzwa pa150 ℃ pa3.5MPa.
Inogona kuonekwa kubva pamigumisiro yekuedza muFigure 1 kuti FC-FR220S ine basa rakanaka mukudzora kurasikirwa kweHTHP pasi pezvakasiyana-siyana zvemunyu, uye ine kushanda kwakadzikama uye kupikisa kwemunyu kwakanyanya.
2. FC-FR220S ine yakanakisa kugadzikana kwekupisa.Kuedza kwemukati kunoitwa kuongorora tembiricha yekudzivirira yeFC-FR220S chigadzirwa mu30% brine slurry nekuwedzera zvishoma nezvishoma tembiricha yekuchembera yeFC-FR220S.Migumisiro yekuedza inoratidzwa mumufananidzo 2:
Remark: HTHP kurasikirwa kwemvura kunoedzwa pa150 ℃ uye 3.5MPa.
Zvinogona kuvonekwa kubva pamhedzisiro yekuyedza muMufananidzo 2 kuti FC-FR220S ichiri nebasa rakanaka mukudzora kurasikirwa kweHTHP pa220 ℃ nekuwedzera kwekushisa, uye ine tembiricha inodzivirira uye inogona kushandiswa kutsime rakadzika uye tsime rakadzika. kuchera.Iyo data yekuyedza inoratidzawo kuti FC-FR220S ine njodzi yekupisa tembiricha yakanyanya pa240 ℃, saka hazvikurudzirwe kuishandisa pakupisa uku kana pamusoro.
3. FC-FR220S ine kugarisana kwakanaka.Kuita kweFC-FR220S mushure mekuchembera pa200 ℃ mumvura yegungwa, brine yakasanganiswa uye saturated brine drilling fluid masisitimu inoongororwa kuburikidza nekuyedza murabhoritari.Mibairo yekuedza inoratidzwa muTafura 2:
Tafura 2 Yekuongorora Kuita Zvekuita kweFC-FR220S mune Yakasiyana Drilling Fluid Systems.
| Item | AV mPa.s | FL API ml | FL HTHP ml | Remark |
| Mvura yegungwa yekuchera mvura | 59 | 4.0 | 12.4 | |
| Compound brine drilling fluid | 38 | 4.8 | 24 | |
| Saturated brine drilling fluid | 28 | 3.8 | 22 |
Zvinogona kuonekwa kubva mumhedzisiro yekuyedza muTebhurari 2 kuti FC-FR220S ine kuenderana kwakanaka uye yakanakisa kurasikirwa kwemvura yekudzora HTHP kurasikirwa kwemvura yekuchera masisitimu emvura yekuchera semvura yegungwa, yakasanganiswa brine uye saturated brine, nezvimwe.
