Ama-polymers we-pac olwela amanzi asuselwa emanzini asuselwa emanzini

I-Polyanionic Cellulose (PAC) ama-polymers adlala indima ebalulekile kumanzi okumba asuselwa emanzini asuselwa emanzini, akhonza njengezengezo ezibalulekile zokuthuthukisa izakhiwo ze-fluid futhi uthuthukise ukusebenza kokumba.

I-Ocudroduction kumanzi okumba amanzi asuselwa emanzini:

Amanzi okumba asuselwa emanzini asuselwa emanzini, abizwa nangokuthi udaka, asemqoka embonini yokumba izizathu ezahlukahlukene. Basiza ekupholiseni futhi bathambisa i-drill bit, bephethe izithombo zokumba, ukugcina ukuqina komthombo, nokuvimbela ukulimala kokwakheka. Phakathi kwezinto eziningi zokushayela uketshezi, ama-polymers afana ne-PAC edlala indima ebalulekile ekufezekiseni izakhiwo zoketshezi ozithandayo.

Ama-2.Charoctissipintrints of Polyanionic Cellulose (PAC) ama-polymers:

I-Polyanionic Cellulose iyi-polymer esolulekayo enamanzi etholakala ku-cellulose, enezakhiwo ezihlukile ezenza ilungele ukumba izicelo ze-fluid. Ezinye izici ezibalulekile ze-PAC polymers zifaka:

I-allobulity yamanzi: I-PAC polmers ekhombisa i-solubity yamanzi ephezulu, ivumela ukuhlakazeka okulula nokufakwa kumanzi okumba okususelwa emanzini.

Ukulawulwa kwe-Viscosity: Banikela ekuphepheni kwe-viscosity ku-drive fluids, okwenza uketshezi lokuthwala ukusikwa kwe-dring ngokuphumelelayo nokugcina ukuqina komthombo.

Ukulawulwa kokulahlekelwa koketshezi: I-Pac Polymers Act njenge-fluad elahlekile yokulawula ukulahla ukulawula, yakha ikhekhe elincanyana, elingenakufinyeleleka odongeni lwe-Wellbore ukuvikela ukulahleka koketshezi ekwakhiweni.

Ukuqina okushisayo: Lawa ma-polymers anokuqina okushisayo, ukulondolozela ukusebenza kwabo emazingeni okushisa aphezulu ahlangabezana nakho ngesikhathi sokudla.

Ukuvumelana: I-PAC polmers iyahambisana nezinye izengezo ezisetshenziswa kakhulu ku-dring fluid, anjengezinkawu, ama-lubting agents, ama-lubthents, kanye nama-lubthring.

3.Ukuhlekiswa kwama-polmers e-PAC kumanzi okumba okusekelwe emanzini:

I-PAC polymers ikhonza imisebenzi eminingi ku-fluids esuselwa emanzini asuselwa emanzini, okufaka isandla ekusebenzeni koketshezi kanye nokusebenza kahle:

Ukuguqulwa kwe-VisCosity: Ngokushintsha okuhlushwa kwama-polymers e-PAC, i-viscosity yoketshezi lokumba ingahlelwa ukuze ihlangabezane nezidingo ezithile ezichazwe yizici zokumba kanye nezimo zokumba. Ukulawulwa okufanele kwe-viscosity kuqinisekisa ukusikwa okusebenzayo kokuthuthwa kwezokuthutha kanye nokuqina komthombo.

Ukulawulwa kokulahleka kwe-Fluid: I-PAC polmers yakha ikhekhe elincanyana, eliphansi le-permeability odongeni lwe-Wellbore, kunciphisa ngokuphumelelayo ukulahleka koketshezi ekwakhiweni. Lokhu kusiza ukugcina ingcindezi ye-hydrostatic, kunciphise ukulimala kokwakha, futhi kuthuthukise ukusebenza kahle kokumba.

Ukulawulwa kweReology: I-PAC polmers ithonya izakhiwo zesimbozo soketshezi lokumba, kufaka phakathi iphuzu lesivuno, amandla we-gel, kanye nenkomba yokuziphatha ye-flow. Ukulungiselela i-Rheology kuqinisekisa ukusebenza okubushelelezi kokumba futhi kusiza ukujikeleza okusebenzayo kodaka.

Ukuhlanza imbobo Lokhu kuvimbela ukunqwabelana kokuqongelela phansi komgodi, kunciphisa ubungozi bepayipi elinamathele nezinye izingozi zokumba.

Ikhwalithi yekhekhe yekhekhe: I-PAC POLYMERS ifaka isandla ekwakhekeni kwekhekhe lekhwalithi ephezulu nge-Uniform perwerness kanye ne-permeability ephansi. I-Filter Cled Cake ethuthukiswe kahle ihlinzeka ngokuvikelwa kahle kwe-Wellbore futhi inciphise ukulimala kokwakheka.

4.Benehits of PAC polmers ekusebenzeni kokumba:

Ukufakwa kwama-polmers we-PAC kumanzi okumba amanzi asuselwa emanzini kunikeza izinzuzo eziningana ezithuthukisa ukusebenza kahle kokumba, ubuqotho bezezimali, nokusebenza okusebenzayo okuphelele:

Ukuqina okuthuthukile kwe-SHOVE: I-PAC polymers isiza ukugcina ukuqina komthombo ngokulawula ukulahleka koketshezi kanye nokunciphisa ukulimala kokwakheka. Lokhu kunciphisa ubungozi bokuwa kahle, ipayipi elinamathele, nezinye izingqinamba ezihlobene nokumba.

Izinga lokumba elithuthukisiwe: Ngokwenza kahle izakhiwo ze-fluid ezinjengokusobala kanye nokulahleka koketshezi, ama-polymers e-PAC enza lula amazinga okumba ngokushesha, okuholela ekutheni izindleko zokumba kanye nokunciphisa izindleko zokusebenza.

Ukuvikelwa Kwemithi: Ukwakheka kwekhekhe lekhwalithi ephezulu nge-PAC polmers kuvikela ukwakheka kusuka ekuhlaselweni koketshezi futhi kugcina ubuqotho beRaservoir. Lokhu kubaluleke kakhulu ekwakhekeni okubucayi okuthambekele ekulimazeni.

Ukumelana Nezinga lokushisa Lokhu kuqinisekisa ukusebenza kwamanzi okungaguquki kanye nokwethenjwa ngaphansi kwezimo eziyinselele.

Ukuvumelana kwemvelo

Ama-polyanionic cellulose (PAC) ama-polymers anezengezo ezisemqoka kumanzi okumba asuselwa emanzini asuselwa emanzini, anikeze izinzuzo eziningi ezinhlobonhlobo ezithuthukisa ukusebenza kahle kokumba, ubuqotho bezemvelo, kanye nokusimama kwemvelo. Izakhiwo nemisebenzi yazo eyingqayizivele ziba neqhaza elilawulwa yi-fluodi, ukuncishiswa kokulahlekelwa koketshezi, ukuhlanza umgodi, nokuvikelwa kokwakheka, ukuthuthukisa ukusebenza kahle kokushayela kanye nokuqinisekisa ukwakhiwa okuhle.
