Isingeniso se-carboxymethyl celtuleose ye-dripling fluid

I-Carboxymethyl Cellulose (CMC) iyindawo ehlanganisiwe ye-polymer etholwe ukuguqulwa kwamakhemikhali kwe-mobile cellulose futhi isetshenziswa kabanzi kwizimboni eziningi. Ekuvuthayo uketshezi, i-carboxymethyl celtuleose idlala indima ebalulekile njenge-simizer ebalulekile ne-stabilizer. Kuthuthukisa ukusebenza kahle nokuphepha kokusebenza kokumba ngokwenza ngcono ukubonakala kanye ne-bheological Properties yoketshezi lokumba nokuvimbela imvula yesigaba esiqinile.

1. Izici eziyisisekelo ze-carboxymethyl cellulose

Isakhiwo samakhemikhali: Ukwakheka kwamangqamuzana kwe-carboxymethyl celtulose kuqukethe i-carboxymethyl (-ch2cooh) esikhundleni, okwenza ama-molecule awo akhokhiswe kabi futhi abe ne-solubiclicity ethile. I-CMC itholakala ngama-molekyuli wemvelo wemvelo wemvelo futhi athathe indawo ingxenye ye-hydroxyl (oh) enamaqembu e-carboxymethyl.

I-Solubity yamanzi: I-Carboxymethyl Cellulose ine-soubelity ephezulu emanzini futhi yakha isixazululo se-colloidal e-viscous. Le mpahla ikwenza kube yinqwaba efanelekile ekudleni uketshezi, olungathuthukisa amandla okumiswa kanye nezimbotshana zoketshezi lokumba.

Ukuguqulwa: Isisindo se-molecular sika-CMC, izinga lokufaka esikhundleni, i-solubility nezinye izakhiwo zingashintshwa ngokuya ngesidingo. Lokhu kuvumela ukuthi kukhethwe futhi kwenziwe kahle ngokuya ngezidingo zangempela ezinhlotsheni ezahlukahlukene zoketshezi lokumba.

2. Iqhaza le-carboxymethyl cellulose kumanzi okumba

Umphumela Wokuqina Ukubonakala okuphezulu kusiza ukumisa okwesikhashana nokuhambisa izithombo, kunciphise ukubekwa kwezinhlayiya eziqinile ku-fluid wokumba, futhi kuvikele ukuvalwa komthombo. Ngaphezu kwalokho, umphumela wokuqina we-CMC angathuthukisa umthamo wokuphamba uketshezi futhi aqinisekise ukuthi uketshezi oludonsayo lungagcina izakhiwo ezinhle zesimbozo ngaphansi kwezinga lokushisa eliphakeme kanye nemibandela ephezulu yokucindezela.

Ukusetshenziswa kwempahla okwenziwe nge-Rheological: Izakhiwo ze-Rheological of fluring fluid zithinta ngqo ukusebenza kahle nokuphepha kokusebenza kokumba. I-CMC ingaguqula ijika le-bherve loketshezi lokumba ukuze licindezelwe kahle isivuno kanye ne-viscosity yokubhekana nezimo ezihlukile zokumba. Isengezo sayo singathuthukisa izici zokugeleza komoya odonsa phansi, ukuze uketshezi lokudonsa lusakwazi ukugcina isimo esizinzile lapho sihlangabezana nezimo eziphakeme zokugeleza noma izimo ezinzima zezwe, futhi zigweme ukuguquguquka ngokweqile kwengcindezi.

Vimbela ukuhanjiswa kwesigaba esiqinile: I-Carboxymethyl Cellulose ingavimbela ngempumelelo ukwakheka kwezulu okuqinile kwesigaba sokushayela uketshezi futhi kuqinisekiswe ukuqina koketshezi lokumba. Ngesikhathi senqubo yokumba, ukuhanjiswa kwezulu kwesigaba esiqinile (okufana nokusika, udaka, njll.) Kuzofaka uketshezi oludonsa njengokujikeleza okuncane. I-CMC isiza ukugcina izinhlayiya eziqinile zimisiwe futhi zivikele ukushiswa kwezulu ngokwandisa i-viscosity kanye nokuhlakazwa koketshezi, ngaleyo ndlela kugcina uketshezi loketshezi lokumba.

Thuthukisa ushukela futhi unciphise ukuhudula: Emithonjeni ejulile noma okushisa okuphezulu kanye nemithombo yokucindezela ephezulu, lapho i-fluority yofuba lokushayela iwohloka, yehlise ukumelana ngoketshezi, futhi kuthuthukise ukusebenza kahle koketshezi, futhi kuthuthukise ukusebenza kahle kokushayela. Ngasikhathi sinye, i-CMC inganciphisa ukulahleka kokuhwamuka koketshezi lokumba futhi kunciphise ukungqubuzana phakathi kwe-drill bit kanye nodonga kahle, kunciphisa ukusetshenziswa kwamandla ekusebenzeni kokumba.

I-Lubrication: I-CMC ingadlala nendima ethile yokuthambeka, yehlise ukungqubuzana phakathi kwe-drill bit kanye nodonga kahle, nokunciphisa ukugqokwa kwemishini. Ikakhulu ngaphansi kwamazinga okushisa aphezulu kanye nengcindezi ephezulu kanye nezimo eziyinkimbinkimbi zezwe, umphumela wokuthambisa ubaluleke kakhulu.

Ukuqina kodonga kahle: I-CMC ingathuthukisa ukunamathela koketshezi lokumba, ukuze ifilimu elincanyana lakhiwa phezu kodonga kahle ukuvikela udonga kahle kusuka ekuweni. Ikakhulu emadwaleni athambile, izingqimba zobumba noma izimo eziyinkimbinkimbi zemvelo ezithambekele ekuweni, le ndima ye-CMC ibaluleke kakhulu.

I-3. Umphumela wohlelo lokusebenza lwe-carboxymethyl cellulose ku-dring fluid

Thuthukisa ukusebenza kahle kokumba: Kusukela i-carboxymethyl celtule

Thuthukisa ukuphepha kokudla: Ukungezelelwa kwe-CMC kusiza ekusebenzeni kahle udonga, kuvikele ukuwa kodonga kahle, futhi kunciphise ukugqokwa kwemishini yokwehla. Ngasikhathi sinye, umphumela wayo wokuqina ungathuthukisa umthamo wokushayela uketshezi futhi unciphise ubunzima bokusebenza nezingozi zokuphepha ezibangelwa uketshezi olungebuhle lwe-drive fluid.

Ukusebenza okubanzi: I-Carboxymethyl celtule Lokhu kwenza ukuthi kusetshenziswe kabanzi ezindaweni ezihlukile zokumba.

Njengomkhulu omkhulu, i-stabilizer kanye ne-Rheology modifier, ukusetshenziswa kwe-carboxymethyl celtuleose ku-dring fluids kubaluleke kakhulu. Kungakhuphula ukubonwa koketshezi lokumba, kuthuthukise izakhiwo zembongo, kuvimbela ukuhanjiswa kwemvula okuqinile, kunciphise ukungqubuzana nokukhulisa ukuqina kodonga kahle, ngaleyo ndlela kunikeze indawo yokusebenza esebenza kahle futhi ephephile yokusebenza kokushayela. Ngokuthuthuka kwesayensi nobuchwepheshe kanye nentuthuko eqhubekayo yobuchwepheshe bokumba, amathemba wesicelo se-carboxymethyl cellulose ku-drive fluid kuzobanzi.
