Ukusetshenziswa kwe-sodium carboxymethyl celtuleose ku-dring fluid

I-Sodium Carboxymethyl Cellulose (CMC-NE FORFED) iyindawo ebalulekile ye-polymer anmer Izakhiwo zayo ezihlukile zikwenza kube yingxenye ebaluleke kakhulu ohlelweni lwe-drive fluid.

1. Izici eziyisisekelo zeSodium Carboxymethyl cellulose

I-Sodium Carboxymethyl Cellulose iyi-anionic cellulose ether ekhiqizwa yi-cellulose ngemuva kokwelashwa kwe-alkali kanye ne-chlororoacetic acid. Isakhiwo saso samangqamuzana siqukethe inani elikhulu lamaqembu e-carboxymethyl, okwenza kube ne-soubelity enhle nokuqina kwamanzi. I-CMC-NA ingakha isixazululo esiphezulu sama-viscosity emanzini, ngokuqina, ukuqina kanye nezakhiwo ezenziwe ngefilimu.

Kukhulu

I-CMC-NA isetshenziswa njengomuntu omkhulu ku-drive fluid. Umsebenzi wayo oyinhloko ukukhulisa i-viscosity yoketshezi lokumba futhi uthuthukise amandla alo okuphatha ukusika ama-rock nokusika kwe-dring. Ukubonakala okufanele koketshezi lokumba kungavimba ngempumelelo ukuwa kodonga kahle futhi kugcinwe ukuqina komthombo.

Ukulahleka kwe-Fluid Ukunciphisa

Ngesikhathi senqubo yokumba, uketshezi lokudonsa luzongena kwimidwebo yokwakheka, okubangela ukulahleka kwamanzi kuketshezi oludonsa, kodwa hhayi kuphela ukuwohloka koketshezi, kepha kungadala ukuwa kahle kodonga kanye nokulimala kwe-reservor. Njengokwehliswa koketshezi, i-CMC-NA ingakha ikhekhe eliminyene elisodongeni kahle, ngempumelelo ukunciphisa ukulahleka kokuhlunga koketshezi lokumba nokuvikela ukwakheka nodonga kahle.

Amafutha okugcoba athambisayo

Ngesikhathi senqubo yokumba, ukungqubuzana phakathi kwe-drill bit kanye nodonga olunzulu kuzokhiqiza ukushisa okuningi, okuholele ekugqokeni okukhulayo kwethuluzi le-drill. Ukugcona kwe-CMC-NA kusiza ukunciphisa ukuxabana, ukunciphisa ukugqokwa kwethuluzi lokushayela, futhi kuthuthukise ukusebenza kahle kokumba.

Isitabili

Ukushayela uketshezi kungahle kuthobeze noma kuhlaze ngaphansi kokushisa okuphezulu kanye nengcindezi ephezulu, ngaleyo ndlela kulahlekelwe ukusebenza kwawo. I-CMC-NA inokuqina okuhle okushisayo kanye nokumelana nosawoti, futhi kungagcina ukuqina koketshezi lokumba ngaphansi kwezimo ezinzima futhi kwandiswe impilo yayo yenkonzo.

3. Indlela yokusebenza kwe-sodium carboxymethyl cellulose

Ukulungiswa kwe-Viscosity

Ukwakheka kwamangqamuzana kwe-CMC-NE kuqukethe inani elikhulu lamaqembu e-carboxymethyl, angakha ama-hydrogen bond emanzini ukwandisa ukubuka kwesixazululo. Ngokushintsha isisindo se-molecular kanye ne-degree degree of CMC-NE, i-viscosity yoketshezi lokumba ingalawulwa ukuze ihlangabezane nezidingo zezimo ezihlukile zokumba.

Ukulawulwa kwe-Filtration

I-CMC-NA Molecule ingakha isakhiwo senethiwekhi esinezici ezintathu emanzini, esingakha ikhekhe eliminyene elisedongeni kahle futhi linciphise ukulahleka kokuhlunga koketshezi lokumba. Ukwakheka kwekhekhe lokuhlunga kuncike hhayi kuphela kulokho okuhlushwa kwe-CMC-NO, kepha futhi nasesimweni sayo samangqamuzana kanye neziqu zokufaka esikhundleni.

Ukufihlela

I-CMC-NA Molecule ingahle i-adderbed ebusweni be-drill bit kanye nodonga olunzulu emanzini ukwakha ifilimu elithambisayo futhi linciphise ukungqubuzana kwezezimali. Ngaphezu kwalokho, i-CMC-NA ingaphinde inciphise ngokungaqondile ukungqubuzana phakathi kwe-drill bit kanye nodonga kahle ngokulungisa i-viscosing yoketshezi lokumba.

Ukuqina okushisayo

I-CMC-NA ingagcina ukuqina kwesakhiwo sayo samangqamuzana ngaphansi kwezimo zokushisa okuphezulu futhi akuthambekele ekuwohlokeni okushisayo. Lokhu kungenxa yokuthi amaqembu e-carboxy kuma-molekyuli awo angakha ama-moleli aqinile e-hydrogen ngama-molecule wamanzi ukumelana nomonakalo wokushisa aphezulu. Ngaphezu kwalokho, i-CMC-NA futhi inokumelana nosawoti okuhle futhi ingagcina ukusebenza kwayo ekwakhekeni kwesawoti. 

4. Izibonelo zohlelo lokusebenza lwe-sodium carboxymethyl cellulose

Enqubweni yokumba yangempela, umphumela wohlelo lokusebenza lwe-sodium carboxymethyl celtuleose lumangalisa. Isibonelo, ekwakhiweni okujulile kokumba kahle, uhlelo oludonsayo oluqukethe i-CMC-NA lwalusetshenziselwa ukulawula kahle ukuqina nokulahleka kwe-Filtration of the Wellbore, kwandise isivinini sokumba, futhi kunciphise izindleko zokumba. Ngaphezu kwalokho, i-CMC-NAS isetshenziswa kabanzi ekuvuthayo kwasolwandle, futhi ukumelana nosawoti okuhle kwenza kube lula ekwenzeni imvelo yasolwandle.

Ukusetshenziswa kwe-sodium carboxymethyl celtuleose ku-dripling fluid kubandakanya izici ezine: ukuqina, ukunciphisa ukulahleka kwamanzi, ukuthambisa kanye nokuzinza. Izakhiwo zayo ezihlukile zomzimba nezamakhemikhali zikwenza kube yingxenye ebaluleke kakhulu ohlelweni lwamanzi okumba. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokumba, amathemba wesicelo se-sodium carboxymethyl cellulose azoba abanzi. Ekucwaningweni okuzayo, ukwakheka kwamangqamuzana kanye nezindlela zokuguqulwa ze-CMC-NA zingalungiselelwe ukuthuthukisa ukusebenza kwazo futhi zihlangabezane nezidingo zezindawo eziyinkimbinkimbi zokumba.
