Nrov Tsim rau Hla Txuas Sodium Carboxymethyl Cellulose - Polyanionic cellulose (PAC) - Yeyuan
Nrov Tsim rau Hla Txuas Sodium Carboxymethyl Cellulose - Polyanionic cellulose (PAC) - Yeyuan Nthuav dav:
Polyanionic cellulose (PAC) yog cov dej-soluble cellulose ether derivative npaj los ntawm kev hloov tshuaj ntawm natural cellulose. Nws yog ib qho tseem ceeb hauv dej-soluble cellulose ether. Nws feem ntau yog siv los ua nws cov ntsev ntsev thiab tau siv dav hauv cov roj drilling, tshwj xeeb tshaj yog cov dej ntsev thiab cov roj hauv ntug dej hiav txwv.
PAC-Application In Petroleum
1. Cov haujlwm ntawm PAC thiab CMC hauv cov roj av yog raws li hauv qab no:
- Cov av nkos uas muaj PAC thiab CMC tuaj yeem ua rau cov phab ntsa zoo ua kom nyias thiab tawv lim ncuav mog qab zib nrog cov permeability tsawg thiab txo cov dej tsis zoo;
- Tom qab ntxiv PAC thiab CMC rau hauv cov av nkos, qhov drilling rig tuaj yeem tau txais qis qis qis qis qis qis, ua kom cov av nkos yooj yim tso cov roj ntim rau hauv nws, thiab ceev nrooj pov tseg cov khib nyiab hauv qhov av nkos;
- Zoo li lwm yam kev tshem tawm, cov av nkos muaj qee lub sijhawm muaj nyob, uas tuaj yeem ruaj khov thiab txuas ntxiv los ntawm kev ntxiv PAC thiab CMC.
2. PAC thiab CMC muaj qhov ua tau zoo hauv qab no hauv kev siv roj av:
- High degree ntawm kev hloov, zoo uniformity ntawm kev hloov, siab viscosity thiab tsawg npaum li cas, zoo txhim kho av nkos kev pab cuam efficiency;
- Zoo noo noo tsis kam, ntsev tiv thaiv thiab alkali tsis kam, haum rau dej tshiab, seawater thiab saturated brine dej raws av nkos;
- Lub ncuav mog qab zib av nkos tsim yog qhov zoo thiab ruaj khov, uas tuaj yeem ua kom ruaj khov ntawm cov av mos thiab tiv thaiv cov ncej phab ntsa;
- Nws yog tsim rau cov av nkos nrog cov khoom siv nyuaj tswj thiab ntau qhov sib txawv.
3. Daim ntawv thov yam ntxwv ntawm PAC thiab CMC hauv cov roj drilling:
- Nws muaj peev xwm tswj tsis tau dej siab, tshwj xeeb tshaj yog cov kua dej poob qis. Nrog rau kev siv tsawg, nws tuaj yeem tswj cov dej poob ntawm qib siab yam tsis muaj kev cuam tshuam rau lwm yam av nkos;
- Nws muaj qhov kub thiab txias tsis kam thiab zoo ntsev ua haujlwm. Nws tseem tuaj yeem muaj peev xwm txo qis dej zoo thiab qee qhov rheology nyob rau hauv qee qhov ntsev concentration. Lub viscosity yuav luag tsis hloov tom qab yaj hauv dej ntsev. Nws yog tshwj xeeb tshaj yog haum rau offshore drilling thiab tob qhov dej;
- Nws tuaj yeem tswj cov rheology ntawm av nkos thiab muaj thixotropy zoo. Nws yog qhov tsim nyog rau cov av nkos hauv dej tshiab, dej hiav txwv thiab dej saturated brine;
- Tsis tas li ntawd, PAC yog siv los ua cov kua cementing los tiv thaiv cov kua dej nkag mus rau qhov hws thiab pob txha;
- Cov lim xovxwm lim dej npaj nrog PAC muaj kev tiv thaiv zoo rau 2% KCl tov (nws yuav tsum tau ntxiv thaum npaj cov lim xovxwm), solubility zoo, siv tau yooj yim, tuaj yeem npaj rau ntawm qhov chaw, gel tsim ceev ceev thiab muaj zog xuab zeb nqa peev xwm. Thaum siv nyob rau hauv tsawg permeability tsim, nws lim xovxwm nyhuv yog zoo heev.
