FC-FR220S Cov Dej Tsis Muaj Dej
Cov dej ntws khiav asulphymon (drilling kua) FC-FC-FC-FR220S tsim los txhim kho qhov xeb ntawm cov copolymer molecule. Lub qhia Monomer pheej rov ua chav nyob muaj qhov chaw loj ntim, uas tuaj yeem nce cov khoom sib txuas thiab txhim kho cov nyhuv ntawm cov khoom siv cov kua dej hathp ntawm kev tswj cov dej hathp Nyob rau tib lub sijhawm, nws muaj peev xwm tawm tsam kub thiab ntsev calcium yog txhawb ntxiv los ntawm kev ua kom zoo dua ntawm kev kub thiab ntsev ua rau muaj kev kub ntxhov. Cov khoom no dhau qhov tsis txaus ntseeg ntawm cov pa roj polymer poob, xws li cov ntsev tsis kam, cov txiaj ntsig tsis zoo ntawm kev tswj cov kua dej hathp tsis zoo. Nws yog cov kua mis polymer tshiab tshiab.

1. FC-FR220s muaj ntsev tsis kam. Los ntawm kev sim sab hauv tsev, kho cov ntsev cov ntsev ntawm cov ntsev tsis kam ntawm FC-Fr220s cov khoom lag luam tom qab kev laus ntawm 200 ℃ hauv cov av nkos nrog cov ntsev sib txawv. Cov txiaj ntsig sim tau pom hauv daim duab 1:
Lus Qhia: Kev sib xyaw ntawm lub hauv paus slurry rau kev ntsuam xyuas: 6% w / v kev ntsuam xyuas av + 1.5% v / v alkali kev daws teeb meem);
Yuav tsum sim cov kua dej HTHP ntawm 150 ℃ ntawm 3.5MPA.
Nws tuaj yeem pom los ntawm kev sim ua hauv daim duab 1 uas FC-fr220
2. FC-FR220s muaj cov khoom ruaj khov zoo. Cov kev sim sab hauv tsev yog kev tshawb fawb txog qhov kub thiab txias ntawm FC-Fr220s cov khoom hauv 30% brine slurry los ntawm maj mam ntxiv qhov kub ntawm FC-Fr220s. Cov txiaj ntsig sim tau pom hauv daim duab 2:
Cim: HTHP cov dej tsis tau kuaj ntawm 150 ℃ thiab 3.5MPA.
Nws tuaj yeem pom los ntawm kev sim ua hauv daim duab 2 uas FC-fr220 Cov ntaub ntawv sim kuj qhia tau tias FC-fr220s muaj kev pheej hmoo ntawm kev ua haujlwm kub kub ntawm 240 ℃, yog li nws tsis pom zoo kom siv nws ntawm qhov kub lossis siab dua.
3. FC-FR220s muaj kev sib raug zoo. Cov kev ua tau zoo ntawm FC-fr220 Qhov kev sim sim tau tshwm sim hauv Rooj 2:
Cov Lus Zaum 2 Kev Ntsuam Xyuas Kev Ntsuam Xyuas Kev Ua Tau Zoo ntawm FC-fr220s hauv cov tshuab sib txawv
| Yam | AV MPa.s | FL DAWB ML | Fl hathp ml | Hais txog |
| Hiav txwv dej Daus Dej | 59 | 4.0 | 12.4 | |
| Compound Brine Drilling Flu | 38 | 4.8 | 24 | |
| Saturated brine drilling kua | 28 | 3.8 | 22 |
Nws tuaj yeem pom los ntawm kev sim hauv rooj 2 uas FC-fr220 muaj kev tswj tau cov dej hiav txwv tsis zoo xws li cov dej hiav txwv, sib xyaw brine thiab lwm yam.
