Kutheni i-CMC ingasetyenziselwa ukomba ioli?

I-Carboxymethyl cellulose (CMC) ifumana ukusetyenziswa okubanzi kwi-oyile yokomba ngenxa yeempawu zayo ezizodwa ezijongene nemingeni emininzi efunyenwe kwinkqubo yokomba. Nasi isizathu sokuba i-CMC isetyenziswe ekombiweni kwe-oyile:

1. Ulawulo lweViscosity yolwelo:

Kwimisebenzi yokomba i-oyile, ulwelo lokugrumba (olwaziwa ngokuba ludaka lokomba) luyimfuneko ekuthambiseni, ukupholisa, kunye nokususwa kobutyobo. Olu lulwelo lufuna ukuba ne-viscosity elawulwayo ukuze luthwale ngokufanelekileyo ukusika ukugrumba ukuya kumphezulu kunye nokugcina uzinzo kumngxuma wokutsala amanzi. I-CMC isebenza njenge-rheology modifier kwi-drilling fluids, ivumela iinjineli ukuba zilawule ngokuchanekileyo i-viscosity kunye nokuhamba kweepropati zodaka. Ngokulungelelanisa ugxininiso lwe-CMC, abaqhubi be-drilling banokulungisa i-viscosity ye-fluid ukuhlangabezana neemfuno ezithile zeemeko ezahlukeneyo zokomba, ezifana namaqondo okushisa ahlukeneyo kunye noxinzelelo lokwakheka.

2. Ulawulo loHlelo:

Ukulawula ukulahleka kolwelo okanye ukuhluzwa kubalulekile ekwembeni ioyile ukuthintela ukonakala kokwakheka kunye nokugcina uzinzo kwiqula. I-CMC isebenza njenge-arhente yokulawula ukuhluza ngokwenza ikeyiki ecekethekileyo, engangenekiyo yokucoca kudonga lomngxuma. Le keyiki yokucoca itywina ngokufanelekileyo ukubunjwa kwaye inciphisa ilahleko yolwelo lokomba kwilitye elijikelezileyo, ngaloo ndlela kuncitshiswe umonakalo wokwakheka kunye nokugcina ingqibelelo yedama. Ngaphaya koko, i-CMC inceda ukomeleza ingqibelelo yekeyiki yesihluzi kunye nokuqina, iqinisekisa uzinzo lwexesha elide lokugrumba.

3. Ukunqunyanyiswa kweMicimbi yoKwemba:

Ngexesha lokugrumba, ukusika amatye kuveliswa njengoko i-drill bit ingena kwi-subsurface formations. Ukunqunyanyiswa okusebenzayo koku kunqunyulwa kulwelo lokomba kubalulekile ukuthintela ukuzinza kunye nokuqokelelana emazantsi equla, nto leyo enokuthintela inkqubela phambili yokomba kwaye ikhokelele kumonakalo wesixhobo. I-CMC isebenza njenge-arhente yokunqumamisa, inceda ukugcina ukusika ukusika kuchithwa kwaye kuxhonywe kulwelo. Oku kuqinisekisa ukususwa ngokuqhubekayo kokusikwa kumthombo kunye nokugcina ukusebenza kakuhle kokomba.

4. UkuNciphisa ukonakala koLwakhiwo:

Kwezinye iimeko zokugrumba, ngakumbi kulwakhiwo olubuthathaka okanye iindawo zokugcina amanzi, ukusetyenziswa kolwelo oluthile lokomba kunokukhokelela kumonakalo wokwakheka ngenxa yokungena kwamanzi kunye nokusebenzisana ne-matrix yamatye. Ulwelo lokomba olusekwe kwi-CMC lubonelela ngezinto eziluncedo ekunciphiseni ukonakaliswa kokwakheka, ngenxa yokuhambelana kwazo noluhlu olubanzi lolwakhiwo kunye nokusebenzisana okuncinci kunye nolwelo lokubumba. Iipropati ezingonakalisi ze-CMC zinceda ukugcina ukufikeleleka kwe-reservoir kunye ne-porosity, ukuqinisekisa izinga eliphezulu lokuvelisa i-hydrocarbon kunye nokusebenza kwendawo yokugcina amanzi.

5. Iingqwalasela zeNdalo kunye noKhuseleko:

Ulwelo olusekwe kwi-CMC luhlala lukhethwa ngenxa yeenzuzo zabo zokusingqongileyo kunye nokhuseleko. Xa kuthelekiswa nezinye izongezo, i-CMC iyabola kwaye ayinayo ityhefu, inciphisa impembelelo yokusingqongileyo kwimisebenzi yokomba kunye nokunciphisa umngcipheko kubasebenzi nakwizilwanyana zasendle. Ukongeza, ulwelo olusekwe kwi-CMC lubonisa ubutyhefu obuphantsi kwaye lubeka iingozi zempilo ezincinci kubasebenzi abombayo, oko kunegalelo kwindawo ekhuselekileyo yokusebenza kwizixhobo zokomba ioyile.

Isiphelo:

Ukuqukumbela, i-CMC isetyenziswa ngokubanzi kwimisebenzi yokomba ioyile ngenxa yokukwazi ukujongana nemingeni eyahlukahlukeneyo ekuhlangatyezwene nayo kwinkqubo yokomba. Ukusuka kulawulo lwe-viscosity yolwelo kunye nokuhluzwa ukuya ekumiseni ukugrumba ukusikwa kunye nokunciphisa umonakalo owenziweyo, i-CMC idlala indima ebalulekileyo ekuphuculeni ukusebenza kokugrumba, ukuqinisekisa uzinzo lwemithombo yamanzi, kunye nokunciphisa impembelelo yokusingqongileyo. Ukuguquguquka kwayo, ukusebenza kakuhle, kunye nokhuseleko kwenza i-CMC ibe sisongezo esithandwayo ekuqulunqweni kolwelo lokomba, ukuxhasa ukuphononongwa kweoyile esebenzayo kunye nezinzileyo kunye neendlela zokuvelisa.
