Umkhiqizi we-Hpmc Cellulose - I-Carboxymethyl cellulose I-CMC-Oil drilling - Yeyuan

Imodeli ye-CMC yebanga le-Petroleum: CMC – HV; I-CMC-LV ; I-CMC-LVT/LV; I-CMC-HVT

Inekhono eliphezulu lokulawula ukulahleka kwamanzi, ikakhulukazi isinciphisi esisebenzayo sokulahlekelwa uketshezi. Ngomthamo ophansi, ungalawula ukulahlekelwa kwamanzi ezingeni eliphezulu ngaphandle kokuthinta ezinye izakhiwo zodaka;

Inokumelana kahle nezinga lokushisa kanye nokumelana nosawoti okuhle kakhulu. Ingase ibe nekhono elihle lokunciphisa ukulahlekelwa kwamanzi kanye ne-rheology ethile ngaphansi kokuhlushwa kukasawoti othile. I-viscosity cishe ayishintshile ngemva kokuncibilika emanzini anosawoti. Ifaneleka ngokukhethekile ukumba ogwini kanye nemithombo ejulile;

Ingakwazi ukulawula kahle i-rheology yodaka futhi ine-thixotropy enhle. Ilungele noma yiluphi udaka olusekelwe emanzini emanzini ahlanzekile, emanzini olwandle kanye ne-saturated brine;

CMC-Application In Petroleum

1. Iqhaza le-CMC emkhakheni kawoyela imi kanje:
- I-CMC inganciphisa ukulahleka kwamanzi odongeni lomthombo futhi inciphise ukungena kodaka;
- Ngemva kokwengeza i-CMC odakeni, umshini wokumba ungathola amandla okugunda okuqala aphansi, ukuze udaka lukhulule kalula igesi egoqwe kulo, futhi imfucumfucu ingalahlwa ngokushesha emgodini wodaka;
- Njengamanye ama-dispersions amisiwe, udaka lokumba lunesikhathi esithile sokuba khona, esingaqiniswa futhi sinwetshwe ngemva kwe-CMC.

2. I-CMC inokusebenza okuhle kakhulu okulandelayo ekusetshenzisweni kwendawo yamafutha:
- Iziqu eziphakeme zokufaka esikhundleni, ukufana okuhle esikhundleni, i-viscosity ephezulu kanye nesilinganiso esiphansi, esingathuthukisa ngempumelelo insizakalo yodaka;
- Ukumelana nomswakama omuhle, ukumelana nosawoti kanye nokumelana ne-alkali, kulungele amanzi ahlanzekile, amanzi olwandle kanye nodaka olusekelwe emanzini olune-brine;
- Ikhekhe lodaka elakhiwe lisezingeni elihle futhi lizinzile, elingakwazi ukusimamisa kahle inhlabathi ethambile
- Ilungele izinhlelo zodaka ezinokulawulwa kokuqukethwe okuqinile okunzima kanye nobubanzi obuhlukahlukene.
