Ojiji nkeCMC dị na OilfieldỤlọ ọrụ mmepụta ihe

A na-eji Carboxymethyl cellulose (CMC) eme ihe n'ọtụtụ ebe na ụlọ ọrụ mmanụ maka ngwa dị iche iche n'ihi njirimara ya na arụmọrụ ya pụrụ iche. Ọ na-eje ozi dị ka ihe mgbakwunye dị iche iche n'ime mmiri ndị na-egwupụta ihe, mmiri mmecha, na cementing slurries, n'etiti ngwa ndị ọzọ. Nke a bụ ụfọdụ ojiji CMC na-ejikarị na ụlọ ọrụ mmanụ:

1. Mmiri mmiri na-egwu ala:

• Viscosifier: A na-eji CMC dị ka onye na-ahụ maka viscosifying na mmiri mmiri na-egwupụta mmiri iji mee ka viscosity dịkwuo elu ma melite ikike ibu mmiri. Ọ na-enyere aka ịnọgide na-enwe nkwụsi ike nke olulu mmiri, kwụsịtụ igbutu, na ịchịkwa mfu mmiri n'oge a na-egwupụta ihe.
• Njikwa mkpofu mmiri mmiri: CMC na-arụ ọrụ dị ka onye na-ahụ maka njikwa mfu mmiri site n'ịme achicha nzacha dị gịrịgịrị, nke na-adịghị agwụ agwụ na mgbidi olulu mmiri, na-egbochi oke mmiri mmiri n'ime nhazi.
• Mgbochi Shale: CMC na-enyere aka igbochi ọzịza na mgbasa nke shale site na ikpuchi ihe mkpuchi shale na igbochi hydration nke ụrọ, na-ebelata ihe ize ndụ nke enweghị ntụkwasị obi nke ọma na ihe omume ọkpọkọ rapaara.
• Nkwụsi ike nke ụrọ: CMC na-eme ka mineral ụrọ na-arụ ọrụ kwụsie ike n'ịgba mmiri mmiri, na-egbochi ọzịza ụrọ na mbugharị, na ịkwalite nrụpụta mkpọpu ihe n'ụdị nwere ụrọ.

2. Mmiri mmiri emecha:

• Njikwa nkwụsị mmiri mmiri: A na-agbakwunye CMC na mmiri mmecha iji chịkwaa mfu mmiri n'ime nhazi n'oge mmecha nke ọma na arụ ọrụ arụ ọrụ. Ọ na-enyere aka ịnọgide na-eguzosi ike n'ezi ihe ma na-egbochi mmebi nhazi.
• Nkwụsi ike Shale: CMC na-enyere aka n'ịkwado shales na igbochi hydration shale na ọzịza n'oge arụ ọrụ arụcha, na-ebelata enweghị nkwụsi ike nke ọma na ịkwalite mmepụta nke ọma.
• Filter Cake Formation: CMC na-akwalite guzobe nke a edo, impermeable nzacha achicha na guzobe ihu, mbenata iche nrụgide na mmiri mmiri Mbugharị n'ime guzobe.

3. Nrụpụta cementing:

• Mgbakwunye na-efunahụ Fluid: CMC na-eje ozi dị ka ihe mgbakwunye mmiri na-efunahụ na cementing slurries iji belata mfu mmiri n'ime nhazi nke nwere ike ime ka ọ dịkwuo mma ma melite nrụpụta ciment. Ọ na-enyere aka hụ na mwepu zonal kwesịrị ekwesị na njikọ ciment.
• Onye na-eme ka ọ dị arọ: CMC na-arụ ọrụ dị ka onye na-emepụta ihe na ciment slurries, na-enye njikwa viscosity na ịkwalite mgbapụta na nkwusioru nke ciment irighiri n'oge ntinye.
• Rheology Modifier: CMC na-agbanwe rheology nke cement slurries, na-emeziwanye ihe na-asọpụta, nguzogide sag, na nkwụsi ike n'okpuru ọnọdụ ala.

4. Enwetara Mmanụ Mmanya (EOR):

• Iju mmiri: A na-eji CMC na arụ ọrụ idei mmiri iji kwalite nrụpụta ọrụ ma melite mgbake mmanụ site na reservoirs. Ọ na-abawanye viscosity nke mmiri ịgba ntụtụ, na-eme ka njikwa ngagharị na arụ ọrụ nchụpụ.
• Iju mmiri Polymer: N'ime ngwa iju mmiri polymer, a na-arụ ọrụ CMC dị ka onye na-ahụ maka ngagharị iji meziwanye nkwekọ nke polymers agbanyere ma mee ka ọ dị mma nke ịchụpụ mmiri.

5. Mmiri na-agbaji:

• Fluid Viscosifier: A na-eji CMC eme ihe dị ka onye na-ahụ maka viscosifying n'ime mmiri na-agbaji hydraulic iji mee ka viscosity mmiri na ihe na-ebu ibu. Ọ na-enyere aka ịmepụta na ịnọgide na-agbaji agbaji na nhazi ahụ ma kwalite njem na ntinye nke proppant.
• Nkwalite arụmọrụ mgbaji: CMC na-enyere aka n'ịkwado iguzosi ike n'ezi ihe ngwungwu proppant na ndakpọ ndakpọ site n'ibelata ntapu mmiri n'ime nhazi yana igbochi nhazi proppant.

Na nchịkọta,carboxymethyl cellulose(CMC) na-arụ ọrụ dị mkpa na ngwa dị iche iche n'ime ụlọ ọrụ mmanụ, gụnyere mmiri na-egwupụta ihe, mmiri mmecha, slurries cimenting, mgbake mmanụ emelitere (EOR), na mmiri na-agbaji. Ntughari ya dị ka onye na-ahụ maka njikwa mmiri, viscosifier, shale inhibitor, na rheology modifier na-eme ka ọ bụrụ ihe mgbakwunye dị oke mkpa maka ịhụ na ọrụ ubi mmanụ na-aga nke ọma.
