Kev siv CMC hauv Petroleum

Petroleum qib CMC qauv: PAC-HV PAC-LV PAC-L PAC-R PAC-RECMC- HVCMC- LV

1. Cov haujlwm ntawm PAC thiab CMC hauv cov roj av yog raws li hauv qab no:

1. Cov av nkos uas muaj PAC thiab CMC tuaj yeem ua rau cov phab ntsa zoo tsim lub ncuav mog qab zib nyias thiab ruaj khov nrog cov permeability tsawg, txo cov dej tsis zoo;

2. Tom qab ntxiv PAC thiab CMC rau cov av nkos, qhov drilling rig tuaj yeem tau txais lub zog pib qis qis, kom cov av nkos yooj yim tso cov roj ntim rau hauv nws, thiab tib lub sijhawm, cov khib nyiab pov tseg sai sai hauv cov av nkos. lub qhov;

3. Drilling av, zoo li lwm yam suspensions thiab dispersions, muaj lub neej txee.Ntxiv PAC thiab CMC tuaj yeem ua kom ruaj khov thiab ua kom lub neej ntev.

2. PAC thiab CMC muaj cov khoom zoo hauv qab no hauv kev siv roj av:

1. High degree ntawm kev hloov, zoo uniformity ntawm kev hloov, siab viscosity, tsawg npaum li cas, zoo txhim kho cov efficiency ntawm av nkos;

2. Zoo noo noo tsis kam, ntsev tsis kam thiab alkali tsis kam, haum rau dej tshiab, dej hiav txwv thiab saturated dej ntsev dej raws li av nkos;

3. Qhov zoo ntawm cov av nkos ncuav mog qab zib yog qhov zoo thiab ruaj khov, uas tuaj yeem txhim kho cov qauv ntawm cov av mos zoo thiab tiv thaiv cov phab ntsa zoo los ntawm kev sib tsoo;

4. Nws yog qhov tsim nyog rau cov av nkos uas nws cov ntsiab lus tsis yooj yim los tswj thiab muaj ntau yam kev hloov pauv.

3. Cov yam ntxwv ntawm CMC thiab PAC hauv cov roj drilling:

1. Nws muaj peev xwm tswj tau cov dej tsis zoo, tshwj xeeb tshaj yog cov khoom siv hluav taws xob poob qis, uas tuaj yeem tswj cov dej poob ntawm qhov siab ntawm qhov qis dua yam tsis muaj kev cuam tshuam rau lwm yam khoom ntawm cov av nkos;

2. Zoo kub kuj thiab zoo heev ntsev kuj.Raws li qee qhov ntsev concentration, nws tseem tuaj yeem muaj peev xwm txo qis dej thiab qee yam rheology.Tom qab tau yaj hauv dej ntsev, qhov viscosity yuav luag tsis hloov, tshwj xeeb tshaj yog haum rau kev siv sab nrauv.Drilling thiab sib sib zog nqus qhov xav tau;

3. Nws tuaj yeem tswj tau cov rheology ntawm cov av nkos, muaj cov thixotropy zoo, thiab tsim nyog rau txhua qhov dej-raws li av nkos hauv dej tshiab, dej hiav txwv, thiab dej ntsev saturated;

4. Tsis tas li ntawd, PAC yog siv los ua cov kua cementing, uas tuaj yeem tiv thaiv cov kua dej nkag mus rau qhov hws thiab pob txha;

5. Cov filtrate npaj nrog PAC tuaj yeem tiv taus 2% KCL tov (yuav tsum tau ntxiv thaum teeb tsa cov filtrate) thiab muaj cov solubility zoo, siv tau yooj yim, tuaj yeem npaj rau ntawm qhov chaw, thiab muaj qhov ceev gelation ceev thiab muaj zog xuab zeb nqa peev xwm.Nws yog siv rau hauv kev tsim, thiab nws cov nyhuv filtration yog zoo heev.
