I-HEC yeBanga lePetroleum: Ukunyusa ukuKhutshwa kweOyile neGesi okuSebenzayo

I-hydroxyethyl cellulose ye-petroleum-grade (HEC), njengesithambisi-manzi esibalulekileyo sepolymer esinyibilikayo emanzini, isilungisi se-rheology, kunye nesiqinisi, siye saba luncedo ngakumbi kwicandelo lokukhutshelwa kweoyile negesi kwiminyaka yakutshanje. Ngokwandiswa okuqhubekayo kwemithombo enzulu, imithombo enzulu kakhulu, kunye nokuhlolwa kweoyile negesi okungaqhelekanga, kufuneka kakhulu ukusebenza kwemithombo yokugrumba, ulwelo lokuqhekeka, kunye nolwelo lokugqiba. I-HEC, ngokunyibilika kwayo okugqwesileyo, ukuzinza kweekhemikhali, kunye nokukwazi kwayo ukuqina, iye yaba sisongezelelo esibalulekileyo sokuphucula ukusebenza kakuhle kokukhupha ioyile negesi.

I-HEC ekumgangatho wepetroliyam ibonakalisa ukunyibilika kwamanzi kakuhle kunye neempawu zokutyeba, yenza ngokukhawuleza inkqubo efanayo xa kulungiswa ulwelo lokugrumba, inyusa ukuxinana kolwelo, ngaloo ndlela iphucula amandla okuthwala ukusika. Ngexesha lokugrumba, ukusika okusezantsi komthombo kufuneka kususwe ngokufanelekileyo phantsi kobushushu obuphezulu, uxinzelelo oluphezulu, kunye neemeko zokujikeleza okukhawulezayo. Ulwelo lokugrumba olujiyileyo lwe-HEC luphucula amandla okumiswa kunye nokuthutha, luthwala ukusika ngokukhawuleza ukuya entloko yomthombo kwaye luphephe umngcipheko wokunamathela kombhobho wokugrumba okubangelwa kukuqokelelana kokusika ezantsi komthombo. Ngaphezu koko, i-HEC ihambelana kakuhle namanzi amdaka kunye namanzi olwandle, igcina ukusebenza okuzinzileyo kokuxinana nakwiindawo ezinosawoti omninzi, okwenza ukuba ifaneleke ngakumbi kumaqonga aselunxwemeni kunye nemisebenzi yokwakheka enzima.

I-HEC ikwadlala indima ebalulekileyo ekugqityweni nasekuqiniseni iinkqubo zolwelo. Iphucula indlela esebenza ngayo i-rheological yolwelo, igcina ukulahleka kolwelo okuphantsi kwaye iphucula umgangatho wekhekhe lesihluzo. Ikhekhe lesihluzo elisemgangathweni ophezulu, elincinci, nelixineneyo liyawahlula ngokufanelekileyo ulwelo lokwakheka, linciphisa umonakalo kwidama kwaye liqinisekise uzinzo lwemveliso elandelayo. Ukongeza, i-HEC iphucula kakhulu ulwelo oluhambelanayo kunye nomthamo wokumiswa kwe-proppant yolwelo lokugqiba, ikhuthaza ukusebenza okuthe tye nokukhuselekileyo.

Kwiteknoloji yokuqhekeka, i-HEC ekumgangatho wepetroliyam yinxalenye ebalulekileyo yolwelo lokuqhekeka olusebenza kakuhle. Amandla ayo okuqina avumela ulwelo lokuqhekeka ukuba luthwale inani elikhulu le-proppant ukuya kwiimfanta ezinzulu, nto leyo efezekisa ukuguqulwa okusebenzayo kwedama. Ngexesha lokuqhekeka, amaqondo obushushu kunye namandla okucheba aphezulu kakhulu, kodwa i-HEC igcina iipropati ezintle ze-viscoelastic, inciphisa ukuhla kwesanti kwaye iphucula inkxaso yokuqhekeka. Kwelinye icala, i-HEC ineempawu zokuwohloka ezilawulekayo; emva kokwakhiwa, inokonakala phantsi kweemeko ezifanelekileyo, ikhulule kwiimfanta, inciphise ukumelana nokubuya, iqinisekise ukuhamba kakuhle kweoyile negesi, kwaye ngaloo ndlela inyusa imveliso. Ngokuphathelele ukhuseleko lokusingqongileyo, i-HEC ayinabungozi, iyabola, kwaye ayicaphukisi, iyenza ibe sisongezelelo seekhemikhali esiluhlaza nesinobuhlobo nokusingqongileyo. Ngokuchasene nogxininiso lwehlabathi kumandla aluhlaza kunye nophuhliso oluzinzileyo, i-HEC ayihlangabezani nje neemfuno zangoku zokusingqongileyo zeekhemikhali ze-oyile kodwa ikwanceda iinkampani ukuphucula amanqanaba azo olawulo lokusingqongileyo. Xa kuthelekiswa neepolymers zemveli zokwenziwa, i-HEC inobuhlobo nokusingqongileyo kunye nokhuseleko lokugcina kunye nokuthuthwa, okuvumela iskimu sokumisela iikhemikhali eziphantsi kunye nezikhuselekileyo kuphuhliso lweoyile negesi.

Ukusetyenziswa kwe-petroleum-gradeI-HECikwandise ukuya kwiindawo ezininzi, kuquka ukubuyiswa kweoyile okuphuculweyo, ukukhuselwa kwereservoir, kunye nokwenza ngcono ukusebenza kwenkqubo yolwelo lokubhola. Ukuhambelana kwayo kwiinkqubo ezahlukeneyo zolwelo kuyivumela ukuba isebenze ngokubambisana nee-surfactants ezahlukeneyo, iityuwa, kunye nee-agents ezidibanisayo ukwenza iinkqubo zeekhemikhali ze-oyile ezinemisebenzi emininzi. Umzekelo, ekutsalweni kweoyile enzima, i-HEC inokuphucula i-rheology yenkqubo yokufakwa kwenaliti kwaye yonyuse ukusebenza kakuhle kwenaliti; ekusebenzeni kwemithombo yegesi, inkqubo yokuqina ye-HEC inokuthwala kwaye ikhuphe ulwelo ngempumelelo, iphucule imveliso yemithombo yegesi.

Ngenxa yokuqina kwayo okugqwesileyo, ukumiswa kwayo, iimpawu zokulungiswa kwe-rheological, kunye neempawu ezilungileyo zokusingqongileyo, i-HEC yomgangatho wepetroliyam iye yaba yinto ebalulekileyo ekukhutshweni kweoyile negesi ngendlela yanamhlanje. Nokuba kukugrumba, ukufaka i-samente, ukuqhekeka, okanye imisebenzi yokugqiba, i-HEC inokuphucula kakhulu ukusebenza kakuhle kwenkqubo kunye nokhuseleko lokusebenza, inegalelo kuphuhliso olusebenzayo kunye nokusetyenziswa okuzinzileyo kwezixhobo zeoyile negesi.
