I-CMC (iCarboxymethyl Cellulose) sisongezo sekhemikhali esisetyenziswa kakhulu kushishino lokomba ioyile, ikakhulu njengento etyebisayo kunye nokuzinzisa ulwelo lokomba. Impembelelo yayo ekusebenzeni kakuhle kokugaya i-multifaceted kwaye ingaxoxwa kwiimbono zokuphucula ukusebenza kwe-drilling fluid, ukunciphisa iingxaki ngexesha lokugaya, kunye nokuphucula inkqubo yokugaya.
1. Imisebenzi esisiseko ye-CMC
isiphumo sokuqina
I-CMC inokunyusa kakhulu i-viscosity yolwelo lokomba. Lo mhlaba ubalulekile kwimisebenzi yokomba kuba ulwelo olujiyileyo lokwemba lunokubonelela ngesakhono sokuthwala esingcono kunye nesakhono sothutho, lunceda ekususeni ukusikwa kumthombo kunye nokuthintela ukubekwa kwabo. Kwangaxeshanye, i-viscosity ephezulu inceda ukugcina ukunqunyanyiswa okulungileyo kwiifom ezintsonkothileyo kwaye kuthintele ukusika ukuvala iqula.
uzinzo lolwelo
I-CMC inonyibiliko olomeleleyo lwamanzi kunye nobushushu obulungileyo kunye nokumelana netyuwa, evumela ukuba isebenze ngokuzinzileyo phantsi kweemeko ezahlukeneyo zejoloji. Ukuzinza kwayo kweekhemikhali ezigqwesileyo kunye neempawu zokuthambisa zinciphisa iingxaki ezahlukahlukeneyo ezibangelwa ukungazinzi kwe-drilling fluid ngexesha lokugaya, njengemvula yodaka, ukuphunyuka kwegesi, njl.
Nciphisa ilahleko yolwelo lodaka olusekelwe emanzini
Ngokusebenzisa intsebenziswano namanye amacandelo, i-CMC inokunciphisa ngokufanelekileyo ilahleko yesihluzi solwelo lokomba, ngaloo ndlela ithintela amanzi ukuba angangeni kumaleko angaphantsi komhlaba, inciphisa umonakalo kulwakhiwo olujikelezileyo lwamatye, ikhusela udonga lwequla, kwaye ngaloo ndlela iphucula ukusebenza kakuhle kokomba.
2. Impembelelo ethile ye-CMC ekusebenzeni kakuhle kokomba
Ukuphucula ukusebenza kokucoca kolwelo lokomba
Ngethuba lenkqubo yokugaya, ukungqubuzana phakathi kwe-drill bit kunye nokwakheka kuya kuvelisa inani elikhulu lokusika. Ukuba azikwazi ukususwa ngexesha, kuya kubangela ukuphazamiseka ekusebenzeni kokomba. I-CMC iphucula ukunqunyanyiswa kunye nokuthwala umthamo wolwelo lokomba, olunokuthi lukhuphe ngokufanelekileyo ezi zinqumle ngaphandle kwentloko yomthombo ukuqinisekisa ukucoceka komthombo. Lo msebenzi ubaluleke ngakumbi kwiindidi zequla ezintsonkothileyo njengamaqula anzulu, amaqula anzulu kakhulu, kunye namaqula axwesileyo. Inokuthintela ngokufanelekileyo iingxaki ezinje ngokuvala i-wellbore kunye nokuncamathela kancinci, ngaloo ndlela inyusa isantya sokomba.
Ukunciphisa umngcipheko wokuwa kweshaft
Kolunye ulwakhiwo oluthambileyo okanye olukhululekileyo lwamatye, omnye wemisebenzi ephambili yokugrumba ulwelo kukugcina uzinzo kudonga lomthombo. Njengesingqinisiso, i-CMC inokuphucula ukuncamathela kolwelo lokomba, ivumela ulwelo lokomba lwenze ifilim ekhuselayo kudonga lwequla ukuthintela ukudilika kodonga okanye udaka ekungeneni kulwalwa olujikelezileyo. Oku akuphuculi kuphela ukhuseleko lwemisebenzi yokomba, kodwa kunciphisa ixesha lokuphumla elibangelwa ukungazinzi kodonga lwamaqula, ngaloo ndlela kuphuculwe ukusebenza kakuhle kokomba.
Nciphisa ilahleko yolwelo lokomba
Ngethuba lenkqubo yokugaya, i-drilling fluids inokungena kwi-formation yangaphantsi komhlaba, ngakumbi kwiindawo apho ilitye line-porosity ephezulu okanye i-fractures. I-CMC inokulawula ngokufanelekileyo ilahleko yolwelo lokomba kunye nokunciphisa ilahleko yolwelo lokomba kwiipores kunye nokwaphuka. Oku akuncedi kuphela ukugcina iindleko zokwemba, kodwa kwakhona kuthintela ulwelo lokomba ukuba lungalahleki ngokukhawuleza kwaye luchaphazele imisebenzi, ukuqinisekisa ukuba ulwelo lokomba luyaqhubeka nokwenza imisebenzi yalo ngokufanelekileyo.
Ukuphucula ukusebenza kakuhle kokomba kunye nokunciphisa umjikelo wokomba
Ngenxa yokuba i-CMC iphucula ukusebenza kolwelo lokomba, yenza ngcono ekucoceni iqula, ukuzinzisa udonga lwamaqula, kunye nokusikwa kwezinto ezisikiweyo, ngaloo ndlela inciphisa iingxaki ezahlukeneyo ezifunyenwe ngexesha lenkqubo yokomba kunye nokuqinisekisa ukuba umsebenzi wokomba unokuhamba kakuhle. kunye nokusebenza ngokufanelekileyo. Ukuzinza kunye nokucoca ukusebenza kwe-drilling fluid kuchaphazela ngokuthe ngqo inkqubela phambili yokugaya. Ukusetyenziswa kwe-CMC kwandisa isantya sokomba, ngaloo ndlela kunciphisa umjikelo wokomba kunye nokunciphisa iindleko zokusebenza zizonke.
3. Imizekelo yesicelo kunye neziphumo ezibonakalayo ze-CMC
ukugrumba iqula elinzulu
Kwi-deep well drilling, njengoko ubunzulu bokwemba bukhula kwaye uxinzelelo lwe-wellhead luyanda, ukuzinza kunye nokumiswa kwe-drilling fluid kubaluleke kakhulu. Ngokongeza i-CMC, i-viscosity ye-drilling fluid inokwandiswa, ukuthwala amandla okusikwa kunokuphuculwa, kwaye ukujikeleza okugudileyo kolwelo lokomba kunokuqinisekiswa. Ukongeza, i-CMC inokunciphisa ngokufanelekileyo inkcitho yexesha elibangelwa kukudilika kodonga kunye nokuvuza, iphucula ukusebenza kakuhle kokomba onzulu.
Ukushisa okuphezulu kunye nokubunjwa koxinzelelo oluphezulu
Kwizakhiwo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu, ulwelo lokomba kufuneka lube nokuzinza okuphezulu kwe-thermal kunye nokumelana noxinzelelo. I-CMC ayinako ukwenza isiphumo esityebileyo kuphela kwiqondo lobushushu eliqhelekileyo, kodwa ikwagcina uzinzo oluhle kwiindawo eziphakamileyo zobushushu ukunqanda ukuthotywa kokusebenza kolwelo. Kwizicelo ezisebenzayo, i-CMC inciphisa ilahleko yokugrumba ulwelo ngexesha lokugrumba kwiindlela ezilolo hlobo kwaye inciphisa ixesha lokuphumla elibangelwa kukwemba iingxaki zolwelo.
ukugrumba iqula elithe tyaba
Ngexesha lokugaya amaqula anqamlezileyo, ekubeni ukuzinza kodonga lomthombo kunye nokususwa kwe-cuttings kunzima kakhulu, ukusetyenziswaCMC njenge-thickener ineempembelelo ezibalulekileyo. I-CMC inokuphucula ngokufanelekileyo i-rheology yolwelo lokomba, incede ulwelo lokomba lugcine ukunqunyanyiswa okuhle kunye nesakhono sothutho, ukuze ukusika kukhutshwe ngexesha, kuthintelwe iingxaki ezinjengokuxinga kunye nokuvalwa, kunye nokuphucula ukusebenza kakuhle kokomba othe tye.
Njengesongezo esisebenzayo sokugrumba ulwelo, isicelo se-CMC kwinkqubo yokomba siphucula kakhulu ukusebenza kakuhle kokomba. Ngokwandisa i-viscosity, uzinzo kunye neempawu ze-rheological zokwemba ulwelo, i-CMC idlala indima ebalulekileyo ekucoceni i-wellbore, ukunciphisa ukudilika kodonga, ukulawula ilahleko yolwelo, kunye nokunyusa isantya sokomba. Ngophuhliso oluqhubekayo lwetekhnoloji yokomba, i-CMC inethemba elibanzi losetyenziso kwiindawo ezahlukeneyo ezintsonkothileyo kwaye iya kuqhubeka idlala indima ephambili kwimisebenzi yokomba yexesha elizayo.
