FC-FR220S Cov tshuaj ntxiv rau kev tswj cov kua dej poob
Cov kua dej tswj kev poob sulphonate copolymer (drilling fluid) FC-FR220S siv lub tswv yim ntawm kev tsim qauv molecular los txhim kho qhov rigidity ntawm copolymer molecule. Lub monomer repeating unit uas tau qhia muaj qhov chaw loj, uas tuaj yeem ua rau kom muaj kev cuam tshuam steric thiab txhim kho cov nyhuv ntawm cov khoom ntawm kev tswj HTHP kua dej poob; Tib lub sijhawm, nws lub peev xwm los tiv taus kub thiab ntsev calcium tau txhim kho ntxiv los ntawm kev ua kom zoo dua ntawm qhov kub thiab ntsev monomers. Cov khoom no kov yeej qhov tsis zoo ntawm cov kua polymer tswj kev poob, xws li kev tiv taus shear tsis zoo, kev tiv taus ntsev calcium tsis zoo, thiab cov txiaj ntsig tsis zoo ntawm kev tswj HTHP kua dej poob. Nws yog cov kua polymer tswj kev poob tshiab.

1. FC-FR220S muaj zog tiv taus ntsev. Los ntawm kev sim sab hauv tsev, kho cov ntsev ntawm cov kua dej drilling uas siv rau kev soj ntsuam los tshawb xyuas qhov tsis kam ntsev ntawm FC-FR220S cov khoom tom qab laus ntawm 200 ℃ hauv cov av nkos nrog cov ntsev sib txawv. Cov txiaj ntsig ntawm kev sim tau qhia hauv Daim Duab 1:
Lus Cim: Cov khoom sib xyaw ntawm cov dej hauv paus rau kev ntsuam xyuas: 6% w/v sodium av + 4% w/v kev ntsuam xyuas av + 1.5% v/v alkali kua (40% concentration);
Kev poob kua dej HTHP yuav tsum raug kuaj xyuas ntawm 150 ℃ ntawm 3.5MPa.
Los ntawm cov txiaj ntsig sim hauv Daim Duab 1, FC-FR220S muaj kev ua tau zoo heev hauv kev tswj cov kua dej HTHP poob hauv qab cov ntsev sib txawv, thiab muaj kev ua tau zoo ruaj khov thiab tiv taus ntsev zoo heev.
2. FC-FR220S muaj kev ruaj khov zoo heev. Kev sim sab hauv tsev tau ua los tshawb xyuas qhov txwv tsis pub kub ntawm cov khoom FC-FR220S hauv 30% brine slurry los ntawm kev maj mam nce qhov kub ntawm FC-FR220S. Cov txiaj ntsig ntawm kev sim tau pom hauv Daim Duab 2:
Lus Cim: HTHP kua poob raug sim ntawm 150 ℃ thiab 3.5MPa.
Los ntawm cov txiaj ntsig sim hauv Daim Duab 2, FC-FR220S tseem muaj lub luag haujlwm zoo hauv kev tswj cov kua dej HTHP poob ntawm 220 ℃ nrog rau qhov kub nce, thiab muaj kev tiv taus kub zoo heev thiab tuaj yeem siv rau qhov dej tob thiab qhov dej tob heev. Cov ntaub ntawv sim kuj qhia tau tias FC-FR220S muaj kev pheej hmoo ntawm kev kub siab ntawm 240 ℃, yog li nws tsis pom zoo kom siv nws ntawm qhov kub no lossis siab dua.
3. FC-FR220S muaj kev sib raug zoo. Kev ua tau zoo ntawm FC-FR220S tom qab laus ntawm 200 ℃ hauv dej hiav txwv, cov dej ntsev sib xyaw thiab cov kua dej ntsev uas tau nqus tau raug tshawb xyuas los ntawm kev sim hauv chaw kuaj mob. Cov txiaj ntsig ntawm kev sim tau qhia hauv Rooj 2:
Rooj 2 Cov txiaj ntsig ntawm kev ntsuam xyuas kev ua tau zoo ntawm FC-FR220S hauv cov txheej txheem Drilling Fluid sib txawv
| Khoom | AV mPa.s | FL API ml | FL HTHP ml | Lus Cim |
| Cov kua dej hauv dej hiav txwv | 59 | 4.0 | 12.4 | |
| Cov kua dej sib xyaw ua ke | 38 | 4.8 | 24 | |
| Cov kua dej ntsev uas tau nqus los ntawm kev khawb av | 28 | 3.8 | 22 |
Los ntawm cov txiaj ntsig sim hauv Rooj 2, FC-FR220S muaj kev sib raug zoo thiab yog qhov tswj kev poob kua zoo heev rau kev tswj HTHP kev poob kua ntawm cov tshuab drilling xws li dej hiav txwv, cov dej ntsev sib xyaw thiab cov dej ntsev saturated, thiab lwm yam.
