Yintoni i-CMC kwiDrilling Mud

I-Carboxymethyl cellulose (CMC) sisongezo esiqhelekileyo esisetyenziswa ekugrumbeni ukwakhiwa kodaka kwishishini leoli kunye negesi.Ukugrumba udaka, okwakwaziwa njengolwelo lokugrumba, lusebenza imisebenzi emininzi ebalulekileyo ngexesha lenkqubo yokomba, kubandakanya ukupholisa kunye nokuthambisa indawo yokomba, ukuthwala i-drill cuttings ukuya phezulu, ukugcina uzinzo kwiqula, kunye nokuthintela ukuvuthuza.I-CMC idlala indima ebalulekileyo ekuphumezeni ezi njongo ngeepropati zayo ezahlukeneyo kunye nemisebenzi ngaphakathi kodaka lokomba:

1. Ulawulo lweViscosity: I-CMC isebenza njenge-rheology modifier kudaka lokwemba ngokwandisa i-viscosity yayo.Oku kunceda ukugcina iipropati ezifunekayo zokuhamba zodaka, ziqinisekisa ukuba zithwala ngokufanelekileyo i-drill cuttings phezulu kwaye inikezela ngenkxaso eyaneleyo kwiindonga zequla.Ukulawula i-viscosity kubalulekile ekuthinteleni imiba efana nokulahleka kolwelo, ukungazinzi kwe-wellbore, kunye nokuncamathela okwahlukileyo.
2. Ulawulo lwelahleko yolwelo: I-CMC yenza ikeyiki ecekethekileyo, enganyangekiyo yokucoca kudonga lomthombo, enceda ekunciphiseni ilahleko yolwelo ekuyilweni.Oku kubaluleke ngakumbi ekuthinteleni ukonakaliswa kokubunjwa, ukugcina ingqibelelo yomthombo, kunye nokunciphisa umngcipheko wokujikeleza okulahlekileyo, apho udaka lokugrumba lubalekela kwiindawo ezinokungena kakhulu.
3. Ukunqunyanyiswa kwe-Drill Cuttings: I-CMC incedisa ukunqunyanyiswa kwe-drill cuttings ngaphakathi kodaka lokomba, lubathintele ekuzinzeni emazantsi equla.Oku kuqinisekisa ukususwa ngokufanelekileyo kokusikwa kwiqula kwaye kunceda ukugcina ukusebenza kakuhle kunye nemveliso.
4. Ukucocwa komngxuma: Ngokwandisa i-viscosity yodaka lokomba, i-CMC iphucula umthamo wayo wokuthwala kunye nokukwazi ukucoca umngxuma.Oku kunceda ekuqinisekiseni ukuba i-drill cuttings ihanjiswa ngokufanelekileyo ukuya phezulu, ikhusela ukuba ingaqokeleli emazantsi omthombo kunye nokuthintela inkqubela phambili yokomba.
5. I-Lubrication: I-CMC inokusebenza njenge-lubricant ekugrumbeni ukwakhiwa kodaka, ukunciphisa ukukhuhla phakathi komtya wokugrumba kunye neendonga zequla.Oku kunceda ukunciphisa itorque kunye nokutsala, ukuphucula ukusebenza kakuhle kokomba, kunye nokwandisa ubomi bezixhobo zokomba.
6. Uzinzo lobushushu: I-CMC ibonisa ukuzinza okuhle kobushushu, igcina i-viscosity yayo kunye nokusebenza kuluhlu olubanzi lweemeko ze-downhole.Oku kuyenza ilungele ukusetyenziswa kwimisebenzi yokomba eqhelekileyo kunye nobushushu obuphezulu.

I-CMC sisongezo esisebenza ngeendlela ezininzi esidlala indima ebalulekileyo ekuqulunqweni kodaka lokomba, lunceda ukunyusa ukusebenza kokomba, ukugcina uzinzo lwe-wellbore, kunye nokuqinisekisa ukhuseleko kunye nokusebenza kakuhle kokomba kwishishini leoli negesi.
