Uyini umehluko phakathi kobumba be-bentonite ne-polymer slurry?

Kokubili i-bentonite kanye ne-polymer slurries yizinto ezivame ukusetshenziswa ezimbonini ezihlukahlukene, ikakhulukazi ekubholeni nasekwakheni. Naphezu kokuba nezicelo ezifanayo, lezi zinto zehluka kakhulu ngokwakheka, izakhiwo kanye nokusetshenziswa.

I-Bentonite:

Ubumba be-Bentonite, owaziwa nangokuthi ubumba lwe-montmorillonite, luyinto yemvelo etholakala emlotheni wentaba-mlilo. Kuyi-smectite yobumba ebonakala ngezindawo zayo eziyingqayizivele zokuvuvukala lapho ivezwe emanzini. Ingxenye eyinhloko ye-bentonite yi-mineral montmorillonite, enikeza izici zayo eziyingqayizivele.

umsebenzi:

Ubumba be-Bentonite ngokuyinhloko lwakhiwe nge-montmorillonite futhi luqukethe amanani ahlukahlukene amanye amaminerali afana ne-quartz, i-feldspar, i-gypsum, ne-calcite.

Isakhiwo se-montmorillonite siyivumela ukuthi imunce amanzi futhi ivuvuke, yakhe into efana nejeli.

isici:

Ukuvuvukala: I-Bentonite ibonisa ukuvuvukala okuphawulekayo lapho ifakwe emanzini, okwenza kube usizo ekuvaleni nasekuxhumeni izinhlelo zokusebenza.

I-Viscosity: I-viscosity ye-bentonite slurry iphakeme, inikeza ukumiswa okuhle kanye nokusikwa okuthwala amakhono ngesikhathi sokumba.

isicelo:

I-Drilling Fluids: Ubumba lwe-Bentonite luvame ukusetshenziswa ekugezeni udaka lwemithombo kawoyela negesi. Isiza ukupholisa nokugcobisa i-drill bit futhi ilethe ama-chips phezulu.

Ukuvala nokuxhuma: Izakhiwo zokuvuvukala kwe-Bentonite ziyivumela ukuthi ivale kahle ama-boreholes futhi ivimbele ukufuduka koketshezi.

inzuzo:

Imvelo: Ubumba be-Bentonite luyinto eyenzeka ngokwemvelo, ehambisana nemvelo.

Ukusebenza Kwezindleko: Ngokuvamile kubiza kakhulu kunezinye izindlela zokwenziwa.

ukushiyeka:

Ibanga lokushisa elilinganiselwe: I-Bentonite ingase ilahlekelwe ukusebenza kwayo emazingeni okushisa aphezulu, inciphise ukusetshenziswa kwayo ezinhlelweni ezithile.

Ukuzinza: I-viscosity ephezulu ye-bentonite slurry ingabangela ukuxazulula uma kungaphathwa kahle.

I-polymer slurry:

Ama-polymer slurries ayinhlanganisela yamanzi kanye nama-polymers okwenziwa aklanyelwe ukufeza izici ezithile zokusebenza. Lawa ma-polymers akhethwe ngenxa yekhono lawo lokuthuthukisa izakhiwo ze-slurry zezinhlelo zokusebenza ezithile.

umsebenzi:

Ama-polymer slurries akhiwe ngamanzi kanye nama-polymers okwenziwa ahlukahlukene njenge-polyacrylamide, i-polyethylene oxide, ne-xanthan gum.

isici:

Ukungavuvukali: Ngokungafani ne-bentonite, i-polymer slurry ayivuvukali lapho ivezwe emanzini. Bagcina i-viscosity ngaphandle kokushintsha okuphawulekayo kwevolumu.

I-Shear Thinning: Ama-polymer slurries ngokuvamile abonisa ukuziphatha kokugunda kwe-shear, okusho ukuthi i-viscosity yawo iyancipha ngaphansi kwengcindezi yokugunda, okwenza kube lula ukupompa nokujikeleza.

isicelo:

Ubuchwepheshe Be-Trenchless: Udaka lwe-polymer luvame ukusetshenziswa e-horizontal directional drilling (HDD) nezinye izinhlelo zokusebenza ezingenazintambo ukuze zinikeze ukuzinza kwe-wellbore nokunciphisa ukungqubuzana.

Ukwakhiwa: Asetshenziswa ezindongeni ze-diaphragm, izindonga eziludaka kanye neminye imisebenzi yokwakha lapho i-viscosity yoketshezi nokuzinza kubaluleke kakhulu.

inzuzo:

Ukuqina kwezinga lokushisa: Ama-polymer slurries angagcina izakhiwo zawo emazingeni okushisa aphezulu, azenze zifanelekele uhla olubanzi lwezinhlelo zokusebenza.

Ukuthambisa okuthuthukisiwe: Izakhiwo zokugcoba ze-polymer slurries zisiza ukunciphisa ukuguga emishinini yokumba.

ukushiyeka:

Izindleko: I-polymer slurry ingabiza kakhulu kune-bentonite, kuye ngokuthi i-polymer ethile esetshenzisiwe.

Umthelela Wendawo Ezungezile: Amanye ama-polymer okwenziwa angase abe nemithelela yemvelo edinga izinyathelo ezifanele zokulahla.

Ekuphetheni:

Ngenkathi i-bentonite ne-polymer slurries inokusetshenziswa okufanayo kuzo zonke izimboni, umehluko wabo ekubunjweni, izakhiwo kanye nokusetshenziswa kuwenza afanelekele izimo ezihlukene. Ukukhethwa phakathi kwe-bentonite ne-polymer slurry kuncike ezidingweni ezithile zephrojekthi enikeziwe, kucatshangelwa izici ezifana nezindleko, umthelela wendawo, izimo zokushisa kanye nezici zokusebenza ezidingekayo. Onjiniyela nabasebenzi kumele bahlole ngokucophelela lezi zici ukuze banqume izinto ezilungele kangcono izinhlelo zabo ezihlosiwe.
