Hydroxyethyl cellulose n'ime mmiri na-agbaji n'ime mkpọ mmanụ

A na-eji Hydroxyethyl cellulose (HEC) eme ihe mgbe ụfọdụ n'ime mmiri na-agbaji agbaji a na-eji arụ ọrụ mgbawa mmanụ, ọkachasị na mgbawa hydraulic, nke a na-akpọkarị fracking. A na-agbanye mmiri mmiri na-agbaji n'ime olulu mmiri na nrụgide dị elu iji mee ka ọkpụkpụ na-eme ka ọkpụkpụ dị na nkume, na-enye ohere maka mmịpụta mmanụ na gas. Nke a bụ otu esi etinye HEC n'ime mmiri na-agbaji:

1. Mgbanwe nke Viscosity: HEC na-eje ozi dị ka onye na-emegharị rheology, na-enyere aka ịchịkwa viscosity nke mmiri na-agbaji. Site n'ịgbanwe ntinye nke HEC, ndị na-arụ ọrụ nwere ike ịhazi viscosity iji nweta ihe ndị a na-achọsi ike na-agbaji, na-eme ka njem mmiri na-arụ ọrụ nke ọma na ịmepụta mgbaji.
2. Njikwa mkpofu mmiri mmiri: HEC nwere ike inye aka na ịchịkwa mfu mmiri n'ime nhazi n'oge mgbawa hydraulic. Ọ na-etolite achicha nzacha dị gịrịgịrị, nke na-adịghị agwụ agwụ na mgbidi mgbaji, na-ebelata mfu mmiri na igbochi mmebi nke nhazi ahụ. Nke a na-enyere aka ịnọgide na-enwe nkwụsi ike mgbaji ma hụ na arụ ọrụ nchekwa nchekwa kacha mma.
3. Nkwusioru Proppant: Mmiri na-agbaji na-enwekarị ihe ndị na-emepụta ihe, dị ka ájá ma ọ bụ seramiiki, nke a na-ebuba n'ime mgbaji ahụ iji mee ka ha meghee. HEC na-enyere aka kwụsịtụ ndị a na-emepụta ihe n'ime mmiri mmiri, na-egbochi nhazi ha na hụ na nkesa otu n'ime ọkpụkpụ.
4. Nhicha nke mgbawa: Mgbe usoro mgbawa ahụ gasịrị, HEC nwere ike inye aka na-ehichapụ mmiri mmiri na-agbaji site na netwọk nke ọma na mgbawa. Viscosity ya na njikwa ihe nchịkwa mmiri na-eme ka mmiri na-agbaji nwere ike nwetaghachi nke ọma site na olulu mmiri ahụ, na-enye ohere ka ịmepụta mmanụ na gas malite.
5. Ndakọrịta na ihe mgbakwunye: HEC dakọtara na mgbakwunye dị iche iche a na-ejikarị na mmiri na-agbaji, gụnyere biocides, corrosion inhibitors, na ndị na-ebelata esemokwu. Ndakọrịta ya na-enye ohere ịmepụta mmiri mmiri na-agbaji agbaji ahaziri maka ọnọdụ olulu mmiri akọwapụtara na ihe mmepụta chọrọ.
6. Ọnọdụ okpomọkụ: HEC na-egosipụta ezigbo nkwụsi ike nke okpomọkụ, na-eme ka ọ dị mma maka iji na-agbaji mmiri na-ekpuchi elu okpomọkụ. Ọ na-ejigide akụrụngwa rheological ya na ịdị irè ya dị ka ihe mgbakwunye mmiri n'okpuru ọnọdụ dị oke egwu, na-eme ka arụmọrụ na-agbanwe agbanwe n'oge arụ ọrụ hydraulic fracturing.

Hydroxyethyl cellulose (HEC) nwere ike ịrụ ọrụ bara uru n'ịmepụta mmiri na-agbaji maka ngwa ịkụ ala mmanụ. Ngbanwe nke viscosity ya, njikwa ọnwụ mmiri, nkwusioru proppant, ndakọrịta na mgbakwunye, nkwụsi ike ọnọdụ okpomọkụ, na ihe ndị ọzọ na-enye aka na arụmọrụ na ihe ịga nke ọma nke arụmọrụ hydraulic. Agbanyeghị, ọ dị mkpa ịtụle njirimara akọwapụtara nke ọdọ mmiri yana ọnọdụ olulu mmiri mgbe ị na-emepụta usoro mmiri na-agbaji nwere HEC.
