Tuam Tshoj Hoobkas rau Carboxymethyl Cellulose Cmc-Putty Powder Qib - Carboxymethyl cellulose CMC-Oil drilling - Yeyuan

Petroleum qib CMC qauv: CMC – HV; CMC-LV; CMC-LVT/LV; CMC - HVT

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 tsis kam. 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 tau qhov 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;

CMC-Application In Petroleum

1. Lub luag haujlwm ntawm CMC hauv cov roj av yog raws li hauv qab no:
- CMC tuaj yeem txo cov dej poob ntawm phab ntsa dej thiab txo qhov permeability ntawm cov av nkos;
- Tom qab ntxiv CMC rau hauv av, qhov drilling rig tuaj yeem tau txais qhov qis qis qis qis, kom cov av nkos yooj yim tso cov roj ntim rau hauv nws, thiab cov khib nyiab tuaj yeem muab pov tseg sai hauv qhov av nkos;
- Zoo li lwm yam kev tshem tawm dispersions, drilling av nkos muaj qee lub sijhawm muaj nyob, uas tuaj yeem ruaj khov thiab txuas ntxiv tom qab CMC.

2. CMC muaj cov kev ua tau zoo hauv qab no hauv oilfield daim ntawv thov:
- Kev hloov pauv qib siab, kev hloov pauv zoo sib xws, siab viscosity thiab tsawg npaum li cas, uas tuaj yeem txhim kho cov kev pabcuam zoo ntawm av nkos;
- 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 txhim kho cov av mos zoo
- Nws yog tsim rau cov av nkos nrog cov khoom siv nyuaj tswj thiab ntau qhov sib txawv.
