Iyini Imisebenzi Yebanga Le-Petroleum Drilling Grade CMC?

Ibanga lokumba uwoyela we-Petroleum iCarboxymethyl Cellulose (CMC) yenza imisebenzi eminingana ebalulekile enqubweni yokumba uwoyela. Nansi imisebenzi yayo eyinhloko:

1. Isilungisi se-Viscosity:

I-CMC isetshenziswa njengesiguquli se-viscosity kuketshezi lokumba ukulawula izakhiwo ze-rheological zoketshezi. Ngokulungisa ukugxila kwe-CMC, i-viscosity yoketshezi lokumba ingalungiswa ukuze ihlangabezane nezidingo ezithile zokusebenza kokumba. Ukulawula i-viscosity efanele kubalulekile ekugcineni ukuqina kwe-hydraulic, ukuvimbela ukulahleka koketshezi, kanye nokuthwala ama-drill cuttings phezulu.

2. Ukulawula Ukulahlekelwa Uketshezi:

I-CMC yenza ikhekhe lesihlungi elincanyana, elingangeneki odongeni lwe-borehole, elisiza ukulawula ukulahlekelwa koketshezi ekubunjweni ngesikhathi sokumba. Leli khekhe lesihlungi lisebenza njengesithiyo, linciphisa ingozi yokungazinzi kwe-wellbore, ukulimala kokubunjwa, nokulahleka kokujikeleza kwegazi. I-CMC ivala ngokuphumelelayo ukwakheka nokuqhekeka okuvunyelekayo, iqinisekisa ukusebenza kahle kokumba.

3. Ukumiswa kanye Nokuvinjelwa kweShale:

I-CMC isiza ukumisa okwesikhashana futhi ithwale izimbobo zokubhoboza nezinye izinhlayiya eziqinile ziyise phezulu, zivimbele ukuzinza kwazo nokunqwabelana kwazo phansi kwe-borehole. Iphinde ivimbele ukugeleza kwamanzi kanye nokuhlakazeka kokwakheka kwe-shale, kunciphisa ubungozi bepayipi elibambekile, ukungazinzi kwe-wellbore, kanye nokonakala kokwakheka. I-CMC ithuthukisa ukusebenza kahle konke kanye nokuphepha kokusebenza kokumba ngokugcina ubuqotho be-wellbore kanye nokunciphisa isikhathi sokuphumula.

4. Ukugcotshwa Nokuncishiswa Kwefriction:

I-CMC isebenza njengesithambiso oketshezini lokumba, inciphisa ukungqubuzana phakathi kwentambo yokubhoboza kanye nodonga lwembobo. Lokhu kunciphisa i-torque nokuhudula intambo yokubhoboza, kuthuthukisa ukusebenza kahle kokubhola kanye nokunciphisa ukuguga nokudilika kwemishini yokumba. I-CMC iphinde ithuthukise ukusebenza kwama-downhole motors namathuluzi okubhola ajikelezayo ngokunciphisa ukungqubuzana nokukhiqiza ukushisa.

5. Izinga Lokushisa Nokuqina Kobusawoti:

I-CMC ikhombisa izinga lokushisa elihle kakhulu nokuzinza kosawoti, okwenza ifanelekele ukusetshenziswa ezindaweni eziningi zokumba, okuhlanganisa izinga lokushisa eliphezulu nezimo ezinosawoti omningi. Igcina izici zayo ze-rheological namandla okulawula ukulahlekelwa uketshezi ngisho nangaphansi kwezimo ezimbi kakhulu ze-downhole, iqinisekisa ukusebenza okungaguquki nokwethembeka emisebenzini yokumba eyinselele.

6. Ayihambisani nemvelo:

I-CMC inobungani bemvelo futhi iyakwazi ukubola, okuyenza ifanelekele ukusetshenziswa ezindaweni zokumba ezibucayi ngokwemvelo. Ayiqukethe izithasiselo eziyingozi noma amakhemikhali anobuthi, anciphisa umthelela endaweni ezungezile nemithombo yamanzi angaphansi komhlaba. Uketshezi lokumba olususelwa ku-CMC luhambisana nemithetho nezindinganiso zemvelo, luqinisekisa izinqubo zokumba ezinzile.

Kafushane, i-petroleum grade drilling grade Carboxymethyl Cellulose (CMC) yenza imisebenzi eminingana ebalulekile kuketshezi lokumba, okuhlanganisa ukuguqulwa kwe-viscosity, ukulawulwa kokulahlekelwa uketshezi, ukumiswa kanye nokuvimbela i-shale, ukuthambisa nokuncishiswa kokungqubuzana, izinga lokushisa kanye nokuzinza kosawoti, kanye nobungane bemvelo. Izakhiwo zayo eziguquguqukayo zinomthelela ekusebenzeni kahle, ukuphepha, kanye nokusimama kokumba uwoyela negesi emhlabeni jikelele.
