I-CMC (i-Sodium Carboxymethyl Selelose) yindawo ebaluleke kakhulu ye-polymer ye-polymer ye-polymer edlala iindima ezahlukeneyo zokugqobhoza ngaphakathi, ngakumbi kwilungiselelo lokulungiselela kunye nokusebenza kwentsebenzo yolwelo. Ukumba okunzulu-yolwandle kuyasebenza kunye neemfuno zobugcisa eziphezulu zobugcisa kunye neemeko ezinzima zokusingqongileyo. Ngokuphuhliswa kwemithombo yeoyile ye-oyile kunye negesi, isikali kunye nobunzulu bokuqhuba okunzulu-ukhula ngokuthe ngcembe. Njengesongezelelo esifanelekileyo sekhemikhali, i-CMC inokuphucula ukusebenza, ukhuseleko kunye nokukhusela kwendalo yenkqubo yokuqhuba.
1. Indima ephambili ekuthandeni amanzi
Ngexesha lokuqhuba okunzulu, ukuqhuba kudlala imisebenzi ebalulekileyo njengokuxhasa udonga lodonga, ukupholisa i-drill bit, kutyeshela i-chips, kunye nokugcina uxinzelelo. I-CMC ngumlawuli ofanelekileyo we-viscofity, iarhente ye-rueological kunye ne-tickener, esetyenziswa ngokubanzi kulungiselelo lwee-fluids. Imisebenzi yayo ephambili iboniswa kule miba ilandelayo:
1.1 Ukutsala kunye nokuhlengahlengisa i-viscofity
Ukugqobhoza okunzulu yolwandle, ngenxa yokunyuka kobunzulu bamanzi kunye noxinzelelo, ulwelo olunxilisayo kufuneka lube ne-viscofity ethile ukuqinisekisa ukuba ulwelo lwayo nokuthwala umthamo. I-CMC inganakho ukusebenza ngempumelelo kwaye inceda ukugcina uzinzo lwe-tyings enzulu kwiinzululwazi ezahlukeneyo kunye noxinzelelo. Ngokuhlengahlengiswa koxinzelelo lwe-CMC, i-viscosity yolwelo olunokuphelelwa kukuqinisekisa ukuba i-fluid ineempawu ezifanelekileyo zokuhamba, ukuze ikwazi ukugeleza ngokukhululekileyo kwiindawo ezinamanzi antsonkothileyo.
1.2 Ukuphucula iipropathi ze-rheodical
Iipropathi ze-ROOOOLOTERTER ZE-DROLLUID ibalulekile kwi-edring enzulu yokuphelisa. I-CMC inokuphucula ubulwele bokuntywila, iyenza ihambe kakuhle ngokufihlakeleyo, ukunciphisa ukungqubana phakathi kwe-Drill Time kunye nodonga lwe-qullbore, ukunciphisa ukusetyenziswa kwamandla ngexesha lokuqhuba izixhobo. Ukongeza, iipropathi ezintle zeRheeology zinokuqinisekisa ukuba i-fluid inokuqinisekisa ngokuphumelelayo kwaye ithintele ukuqokelelwa kwamasuntswana aqinileyo kwi-fluid fluid, ngaloo ndlela ukuphepha iingxaki ezinje ngebhloko.
2. Uzinzo lwe-Westicare kunye nokuNibaza i-Hydrate
Kwinkqubo yokuphenjwa okunzulu kwaselwandle, uzinzo lwe-cepebore luphawu oluphambili. Iindawo ezinzulu zolwandle zihlala zijamelana neemeko ezintsonkothileyo zejografi, ezinjengoxinzelelo oluphezulu, ubushushu obuphezulu, kunye ne-sediment ye-sedimes, enokukhokelela ekulahlekeni kwe-Welybre. I-CMC inceda ukuphucula uzinzo lodonga olukhanyisiweyo kwaye kuthintele ukuwa kwe-Wellbore ngokuphucula i-viscofity kunye neepropathi ze-suheologing ye-fluid fluid.
Ukumba okunzulu yolwandle, ukwenziwa kwee-hydrate (ezinje nge-hydrate yendalo) kukwangumcimbi ongenakutyeshelwa. Ngaphantsi kobushushu obuphantsi kunye neemeko zoxinzelelo oluphezulu, i-hydrate yerhasi yendalo iqhutywa ngokulula ngexesha lokuqhuba kwaye ibangele ukubanjiswa kwe-fluid fluid. Njengearhente efanelekileyo yokusebenzela i-hydration, i-CMC inokuthintela ngokufanelekileyo ukumiswa kwee-hydrate, gcina ulwelo lwe-fluid fluid, kwaye iqinisekise ngenkqubela phambili egudileyo yokuntywila.
3. Nciphisa ifuthe kwendalo
Ngeemfuno zoKhuseleko loKhuseleko lweNkcubeko yezeNdalo, ifuthe kwindalo esingqongileyo ngexesha lokuqhuba eliphakathi lifumene ingqwalaselo ngakumbi nangakumbi. Ukusetyenziswa kwe-CMC ekunciphiseni i-CMC-ry-win-win-win-win-win kunokunciphisa ngokufanelekileyo ukukhutshwa kwezinto eziyingozi kumbhobho wokuntywila. Njengesixhobo sendalo, i-CMC ine-biodegradiance elungileyo kunye nobuhlobo bokusingqongileyo. Ukusetyenziswa kwayo kunokunciphisa ubungozi bolwelo olunxilisayo kwaye lunciphise ungcoliseko kwinkqubo ye-ecosystem.
Ukongeza, i-CMC inokuphucula umgangatho wokuphinda usebenzise i-flud. Ngokulungelelanisa ukusebenza kwentsebenzo ye-flud yokuntywila, ukunciphisa ukuphulukana nolwelo olunxilisayo, kunye nokuqinisekisa ukuba ulwelo lokuntywila lunokuncitshiswa kwakhona, umthwalo kwindawo ye-Marine ngexesha lenkqubo yokuqhuba incitshisiwe. Oku kubaluleka kakhulu kuphuhliso oluzinzileyo lwe-oding enzulu-yolwandle.
4. Ukuphucula ukusebenza ngokukuko nokhuseleko
Ukusetyenziswa kwe-CMC ayiphumi nje ukusebenza kwentsebenzo enzulu yokuphenjwa, kodwa iphucula ukuqhuba ukusebenza kakuhle nokusebenza ngokhuseleko ukuya kwinqanaba elithile. Okokuqala, i-CMC inokwenza ukubamba i-fludlet ibe gqitha kwiimeko ezahlukeneyo zejografi, inciphise i-phenomenon yombhobho wamanzi kunye nobuqhetseba ngexesha lokuqhuba, kunye nokuqinisekisa inkqubela phambili egudileyo yokuqhuba. Okwesibini, intsebenzo yokuntywila i-fluid inokuphucula ukuchaneka nje nokuphepha ukusilela okubangelwa ludonga olungazinzanga okanye ezinye izinto. Ukongeza, i-CMC inokunciphisa ngokufanelekileyo umngcipheko wokutshintsha koxinzelelo olusezantsi, ukunciphisa iimeko eziyingozi ezinje nge-blowows kunye nodaka olunokuthi lwenzeke ngexesha lokuqhuba, kunye nokuqinisekisa ukhuseleko lwemisebenzi.
5. Ukusebenza ngendleko kunye noqoqosho
Nangona ukusetyenziswa kweCmcIya kwandisa iindleko ezithile, ezi ndleko zilawulwa zifakelwe xa kuthelekiswa nokuphuculwa kokuqhuba ngokukuko nokuqinisekisa ukuqinisekiswa. I-CMC inokuphucula uzinzo lolwelo kwaye inciphise imfuno yezinye iikhemiti zemichiza, ngaloo ndlela inciphisa iindleko ze-flud. Kwangelo xesha, ukusetyenziswa kwe-CMC kunokunciphisa ukulahleka kwesixhobo kunye neendleko zokugcina, ukuphucula ukusebenza kwemveliso yokuqhuba, kwaye ke kuzisa izibonelelo zoqoqosho eziphezulu.
Njengesongezelelo esifanelekileyo sekhemikhali, i-CMC idlala indima ebalulekileyo ekuthambekeni kolwandle. Ayinakuphucula ukwenziwa kwentsebenzo yokuqhuba i-flud kwaye iphucule uzinzo lwe-nyibibi, kodwa ikwazi ukuthintela ukungcoliseka kwe-hydrates, kunye nokuphucula ukusebenza nokhuseleko ekusebenzeni. Ngokuphuhliswa okuqhubekayo kwetekhnoloji yokuphembelela enzonzobila yolwandle kunye nokuphuculwa okuqhubekayo kweziko lokukhusela, ukusetyenziswa kwe-CMC kuya kuba nako ngakumbi kwaye ube yinye yezona zinto zibalulekileyo ze-on of grisling.
