FC-FR220S Fluid Poob Control additives
Cov kua dej poob tswj sulphonate copolymer (drilling fluid) FC-FR220S txais lub tswvyim ntawm molecular qauv tsim los txhim kho lub rigidity ntawm copolymer molecule.Cov qhia monomer rov ua dua chav tsev muaj qhov chaw ntim loj, uas tuaj yeem ua rau muaj kev cuam tshuam tsis zoo thiab txhim kho cov txiaj ntsig ntawm cov khoom ntawm kev tswj HTHP kua dej;Nyob rau tib lub sijhawm, nws muaj peev xwm tiv taus qhov kub thiab txias thiab ntsev calcium ntxiv los ntawm kev ua kom zoo dua ntawm qhov kub thiab txias thiab ntsev monomers.Cov khoom no overcomes lub shortcomings ntawm cov pa polymer kua tsis tswj, xws li cov neeg pluag shear kuj, tsis zoo ntsev calcium tsis kam, thiab tsis txaus siab ntawm kev tswj HTHP kua poob.Nws yog ib qho tshiab polymer kua tsis tswj.

1. FC-FR220S muaj zog ntsev tsis kam.Los ntawm kev sim sab hauv tsev, kho cov ntsev cov ntsiab lus ntawm cov kua dej drilling siv rau kev soj ntsuam xyuas cov ntsev tsis kam ntawm FC-FR220S cov khoom tom qab kev laus ntawm 200 ℃ hauv cov av nkos nrog cov ntsev sib txawv.Cov txiaj ntsig kev sim tau pom hauv daim duab 1:
Lus Cim: Cov ntsiab lus ntawm lub hauv paus slurry rau kev ntsuam xyuas: 6% w / v sodium av + 4% w / v ntsuas av + 1.5% v / v alkali tov (40% concentration);
HTHP kua poob yuav tsum tau kuaj ntawm 150 ℃ ntawm 3.5 MPa.
Nws tuaj yeem pom los ntawm cov txiaj ntsig kev sim hauv daim duab 1 tias FC-FR220S muaj kev ua tau zoo hauv kev tswj hwm HTHP kua poob hauv cov ntsiab lus ntsev sib txawv, thiab muaj kev ua haujlwm ruaj khov thiab ua kom muaj ntsev zoo heev.
2. FC-FR220S muaj thermal stability zoo heev.Kev sim sab hauv tsev yog ua los tshawb xyuas qhov ntsuas kub tsis kam ntawm FC-FR220S cov khoom hauv 30% brine slurry los ntawm maj mam nce qhov kub ntawm FC-FR220S.Cov txiaj ntsig kev sim tau pom hauv daim duab 2:
Lus Cim: HTHP kua poob yog kuaj ntawm 150 ℃ thiab 3.5MPa.
Nws tuaj yeem pom los ntawm cov txiaj ntsig kev sim hauv daim duab 2 tias FC-FR220S tseem muaj lub luag haujlwm zoo hauv kev tswj HTHP cov kua dej poob ntawm 220 ℃ nrog qhov nce ntawm qhov kub thiab txias, thiab muaj qhov kub thiab txias tsis kam thiab tuaj yeem siv rau qhov tob tob thiab tob tob. qhov drilling.Cov ntaub ntawv sim kuj qhia tau hais tias FC-FR220S muaj kev pheej hmoo ntawm kev kub siab desorption ntawm 240 ℃, yog li nws tsis pom zoo kom siv nws ntawm qhov kub thiab siab dua.
3. FC-FR220S muaj kev sib raug zoo.Kev ua tau zoo ntawm FC-FR220S tom qab kev laus ntawm 200 ℃ hauv dej hiav txwv, cov brine sib xyaw thiab cov dej saturated brine drilling kua tshuab tau tshawb xyuas los ntawm kev sim ua haujlwm.Cov txiaj ntsig kev sim tau qhia hauv Table 2:
Table 2 Kev Ntsuam Xyuas Kev Ua Haujlwm ntawm FC-FR220S hauv Cov Txheej Txheem Sib Txawv Drilling Fluid Systems
| Yam khoom | AV mPa.s | FL API ml | FL HTHP ml | Lus ceeb toom |
| Hiav txwv dej drilling kua | 59 | 4.0 | 12.4 | |
| Compound brine drilling kua | 38 | 4.8 | 24 | |
| Saturated brine drilling kua | 28 | 3.8 | 22 |
Nws tuaj yeem pom los ntawm cov txiaj ntsig kev sim hauv Table 2 tias FC-FR220S muaj kev sib raug zoo thiab yog cov kua dej tsis zoo rau kev tswj HTHP kua poob ntawm cov kua dej drilling xws li dej hiav txwv, cov dej sib xyaw ua ke thiab cov dej saturated brine, thiab lwm yam.
