Mmetụta nke Hydroxyethyl Cellulose na Oilfields

Hydroxyethyl Cellulose (HEC) bụ polymer soluble mmiri nke a na-ejikarị na ụlọ ọrụ mmanụ na gas dị ka ihe mgbanwe rheology, thickener, na stabilizer. Nke a bụ ụfọdụ mmetụta HEC na mmanụ mmanụ:

1. Njikwa viscosity: A na-eji HEC na-achịkwa viscosity nke mmiri na-egwupụta mmiri na ciment slurries na mmanụ mmanụ. Ọ na-enyere aka ịnọgide na-enwe viscosity kwụsiri ike n'okpuru ọnọdụ dịgasị iche iche, dị ka mgbanwe okpomọkụ na nrụgide.
2. Njikwa nzacha: HEC nwere ike ibelata ọnụego nke mmiri na-efu na mmiri na-egwupụta mmiri na cement slurries, nke na-eme ka njikwa nchịkwa ha dịkwuo mma. Nke a na-enyere aka igbochi nhazi nke achịcha apịtị na-adịghị agwụ agwụ ma na-ebelata ihe ize ndụ nke ọkpọkọ rapaara n'oge a na-egwupụta ihe.
3. Shear thinning: HEC na-egosiputa omume na-egbu egbu, nke pụtara na viscosity ya na-ebelata n'okpuru nrụgide siri ike. Ngwongwo a nwere ike ịba uru na ngwa mmanụ ebe achọrọ obere viscosity n'oge mgbapụta mana nnukwu viscosity chọrọ na olulu mmiri.
4. Nkwụsi ike nke mmiri: HEC na-enyere aka mee ka mmiri na-egwupụta ihe na ciment slurry kwụsie ike site na igbochi nhazi na ịkwagharị nke ihe ndị ahụ kwụsịrị.
5. Ndakọrịta gburugburu ebe obibi: HEC bụ enyi na gburugburu ebe obibi na ọ dịghị emerụ ihe ọ bụla na gburugburu ebe obibi. Ọ naghị egbu egbu ma na-eme ka ọ bụrụ nhọrọ dị mma maka iji mee ihe n'ubi mmanụ.
6. Ndakọrịta na mgbakwunye ndị ọzọ: HEC dakọtara na ọtụtụ ihe mgbakwunye ndị ọzọ a na-eji na mmanụ na gas, gụnyere apịtị mmiri, brines na ciment slurries. Enwere ike iji ya na polymers ndị ọzọ, dị ka xanthan chịngọm, iji melite arụmọrụ nke mmiri na-egwupụta mmiri na ciment slurries.

N'ozuzu, mmetụta nke HEC na mmanụ mmanụ na-eme ka ọ bụrụ ihe mgbakwunye bara uru maka ịkwalite ihe onwunwe nke mmiri na-egwupụta mmiri na ciment slurries. Njikwa viscosity ya, njikwa filtration, omume ịcha mma, nkwụsi ike nke mmiri, ndakọrịta gburugburu ebe obibi, yana ndakọrịta na mgbakwunye ndị ọzọ na-eme ka ọ bụrụ ihe dị mkpa na ụlọ ọrụ mmanụ na gas.
