Ukusebenza okuphezulu kwePAC kulwelo olusekwe emanzini

Ukusebenza okuphezulu kwe-polyanionic cellulose (PAC) sisongezelelo esibalulekileyo kulwelo olusekwe emanzini, olubonelela ngoluhlu lweenzuzo eziphucula ukusebenza kakuhle kokomba, uzinzo lwequla, kunye nokusebenza ngokubanzi. I-PAC yipolymer enyibilikayo emanzini ephuma kwiselulosi, kwaye ukusetyenziswa kwayo kumanzi okomba kunceda ukulawula irheology, ukulahleka kolwelo, kunye nolawulo lokuhluza. Nantsi indlela ukusebenza okuphezulu kwePAC enegalelo ngayo ekusebenzeni kolwelo olusekwe emanzini:

Iimpawu zoMsebenzi oPhezulu wePAC:

1. Ukunyibilika kwamanzi: Ukusebenza okuphezulu kwePAC kunyibilika ngokulula emanzini, okuvumela ukuxubana lula kunye nokusasazeka kwiinkqubo zokwemba ulwelo.
2. Ukutyebisa kunye noLawulo lweRheology: I-PAC isebenza njenge-viscosifier kwi-drilling fluid, inceda ukufezekisa nokugcina i-viscosity efunwayo kunye neempawu ze-rheological. Inika indlela yokuziphatha yokucheba, iququzelele ukumpompa ngexesha lokujikeleza kunye nokubuyiswa kwe-chear xa i-static.
3. Ulawulo lwelahleko yolwelo: I-PAC yenza ikeyiki ecekethekileyo, engangenekiyo yokucoca kudonga lomngxuma, inciphisa ngokufanelekileyo ilahleko yolwelo ekubunjweni kwayo. Oku kunceda ukugcina uzinzo lwe-wellbore, ukuthintela umonakalo wokwakheka, kunye nokunciphisa iindleko ezilahlekileyo zokujikeleza iingxaki.
4. Iqondo lobushushu kunye noZinzo lweSalinity: Ukusebenza okuphezulu kwePAC yenzelwe ukugcina ukusebenza kwayo kunye nokuzinza kuluhlu olubanzi lwamaqondo obushushu kunye namaqondo etyuwa adibana nawo ngexesha lomsebenzi wokomba, kubandakanywa ubushushu obuphezulu kunye neendawo ezinetyuwa eninzi.
5. Ukuhambelana nezongezo: I-PAC ibonisa ukuhambelana kakuhle nezinye izongezo zolwelo lokomba, kubandakanywa izinzisi zodongwe, izithambiso, ii-shale inhibitors, kunye ne-weighting agents. Ingasetyenziswa ngokudityaniswa nezongezo ezahlukeneyo ukulungisa iipropathi zokwemba ulwelo ngokwemiqathango ethile kunye neenjongo.

Okuzuzwayo kwiPAC eSebenza ngokuPhezulu kuLuhlulo oluSekwe ngamanzi:

1. Ukucocwa koMngxuma oPhuculweyo: I-PAC inceda ukunqumamisa ukusikwa kwe-drill kunye ne-debris kulwelo lokomba, ukukhuthaza ukususwa okusebenzayo kumthombo kunye nokuthintela ukuba zingazinzi kwaye zibangele iingxaki ze-downhole.
2. I-Lubricity Eyongeziweyo: Ubukho bePAC kulwelo lokomba kunciphisa ukukhuhlana phakathi komtya wokugrumba kunye nequla, ukuphucula ukusebenza kakuhle kokomba, ukunciphisa itorque kunye nokutsala, kunye nokwandisa ubomi bezixhobo zokomba.
3. I-Wellbore eZinzileyo: I-PAC inceda ukunqanda imiba yokungazinzi kwe-wellbore, efana nokwandiswa kwemingxuma, i-sloughing shale, kunye nokudilika kokwakheka, ngokubonelela ngolawulo olusebenzayo lokuhluza kunye nokugcina imfezeko yequla.
4. Ukonyuka kwamaxabiso okuNgena: Ngokulungisa iipropathi zolwelo lokomba kunye nokunciphisa ilahleko yokungqubana, ukusebenza okuphezulu kwePAC kunokufaka isandla kumazinga okomba okukhawulezayo kunye nokonga ixesha elipheleleyo kwimisebenzi yokomba.
5. Ukuthotyelwa kokusiNgqongileyo noLawulo: Ulwelo lokomba olusekelwe emanzini olune-PAC esebenza kakhulu lubonelela ngeenzuzo zokusingqongileyo kulwelo olusekwe kwi-oyile, kubandakanywa neempembelelo ezincitshisiweyo zokusingqongileyo, ukulahlwa lula, kunye nokuthotyelwa kweemfuneko zolawulo lwemisebenzi yokomba.

Izicelo zoMsebenzi oPhezulu wePAC:

Ukusebenza okuphezulu kwePAC kusetyenziswa kuluhlu olubanzi lweenkqubo zokwemba ulwelo, kubandakanywa:

• Udaka olusekelwe emanzini (WBM): I-PAC yinxalenye ephambili kumanzi ahlaziyekileyo, amanzi etyuwa, kunye neenkqubo zodaka ezisekelwe kwi-brine ezisetyenziselwa izicelo ezahlukeneyo zokomba, kubandakanywa ukuhlola, ukuveliswa kunye nokugqitywa.
• Ukugrumba okuthe tyaba kunye nokwalathise icala: I-PAC inceda ukugcina uzinzo lwe-wellbore kunye nolawulo kwiimeko ezinzima zokomba, ezifana nequla elifikelelayo elandisiweyo, iqula elithe tye, kunye namaqula atenxe kakhulu.
• Ukwemba elunxwemeni: I-PAC ixabiseke ngokukodwa kwimisebenzi yokomba ngaphandle konxweme, apho uqwalaselo lokusingqongileyo, unyino lwezixhobo, kunye nozinzo lwequla zizinto ezibalulekileyo.

Isiphelo:

Ukusebenza okuphezulu kwe-polyanionic cellulose (PAC) kudlala indima ebalulekileyo kumanzi okomba asekelwe emanzini, ukubonelela ngolawulo olubalulekileyo lwe-rheological, ulawulo lwelahleko yolwelo, kunye neempawu zokuzinzisa i-wellbore. Ngokubandakanya ukusebenza okuphezulu kwePAC kwimixube yokwemba ulwelo, abaqhubi banokufezekisa impumelelo ephuculweyo yokomba, uzinzo lwe-wellbore, kunye nokusebenza ngokubanzi, ekugqibeleni kube negalelo kwimisebenzi yokwemba eyimpumelelo nengabizi kakhulu.
