Yini ukusetshenziswa kwe-petroleum grade CMC-LV?

I-Petroleum grade carboxyylllyl cellulose (CMC) ingamakhemikhali abalulekile asetshenziswa embonini kawoyela negesi, ikakhulukazi ku-drive fluid. Ukuqokwa "i-LV" kumi "ngokusobala okuphansi," okukhombisa izakhiwo zayo ezithile zomzimba kanye nokufaneleka kwezicelo ezithile ngaphakathi kokukhishwa kukaphethiloli nokusebenza.

Ukwakheka nezakhiwo ze-petroleum grade CMC-LV

I-Carboxymethyl Cellulose iyi-polymer esolulekayo enamanzi atholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. "I-viscosity ephansi" ehlukile inezakhiwo ezihlukile, kufaka phakathi isisindo esiphansi samangqamuzana, esihumusha ngomphumela ophansi ophansi lapho sichithwa emanzini. Lokhu kwenza kube kuhle ngezicelo ezidinga ushintsho oluncane ekuboniseni uketshezi.

Izakhiwo ezibalulekile:

I-Solubinity: I-Solubity ephezulu emanzini, lula ukuxuba okulula nokusatshalaliswa ngaphakathi kokumba uketshezi.

Ukuqina okushisayo: Kugcina ubuqotho obusebenzayo ngaphansi kwamazinga okushisa aphezulu ahlangabezana nakho ngesikhathi sokumba.

Ukubekezelelana kwe-PH: Kuzinza ngaphesheya kwamazinga e-PH, okwenza kuguquguqukeni ngezindawo ezihlukile zokumba.

I-Viscosity ephansi: Umthelela omncane ekubonakaleni koketshezi lwesisekelo, kubalulekile ukuthola izimo ezithile zokumba.

Ukusetshenziswa kwe-Petroleum Ibanga CMC-LV

1. Ukudonsa uketshezi

Ukusetshenziswa okuyisisekelo kwe-petroleum grade CMC-LV kusekwe ekwakhiweni kwamanzi okumba, owaziwa nangokuthi udaka. Lawa manzi abucayi kwinqubo yokumba ngenxa yezizathu eziningana:

I-Lubrication: Uketshezi lokumba ugcoba i-drill bit, ukunciphisa ukungqubuzana nokugqoka.

Ukupholisa: Basiza ukupholisa i-drill bit kanye nentambo yokumba, ukuvimbela ukushisa ngokweqile.

Ukulawulwa kwengcindezi: Uketshezi oludonsa lunikeza ingcindezi ye-hydrostatic ukuvikela ama-blowaut futhi uzinze kahle.

Ukususwa kokusikwa: Bathutha ukusikwa kwe-dring ebusweni, balondoloze indlela ecacile yokumba.

Kulesi simo, ukubonakala okuphansi kwe-CMC-LV kuqinisekisa ukuthi uketshezi oludonsayo luhlala luphazanyiswa futhi lungafeza ngempumelelo le misebenzi ngaphandle kokuba mkhulu noma i-gelatinous, okungavimbela ukusakazwa nokusebenza kahle nokukhuthaza ukusebenza kahle nokubiyela ukusebenza kahle kanye nokusebenza kahle.

2. Ukulawulwa kokulahlekelwa koketshezi

Ukulawulwa kokulahlekelwa kokulahleka kubalulekile ekusebenzeni kokumba ukuvikela ukulahleka koketshezi lokumba ekwakhekeni. I-Petroleum Ibanga le-CMC-LV lisebenza njenge-ejenti yokulawula ukulahleka koketshezi ngokwakha ikhekhe elincanyana, eliphansi le-permeability ezindongeni ze-Wellbore. Le mgoqo inciphisa ukufakwa koketshezi lokumba ekwakhekeni kwamadwala azungezile, ngaleyo ndlela kulondolozwe ubuqotho bomthombo nokuvimbela ukulimala kokwakheka okungaba khona.

3. Ukuthuthukisa ukuqina kwe-borehole

Ngokufaka isandla ekwakhekeni kwekhekhe lokuhlunga elizinzile, i-CMC-LV isiza ukugcina ukuqina kwe-borehole. Lokhu kubaluleke kakhulu ekwakhekeni okuthambekele ekulinganiseni noma ukuwa. Ikhekhe lokuhlunga lisekela izindonga ze-Wellbore futhi livimbela ukuncibilika noma ukuncipha ngaphakathi, ukunciphisa ingozi yokubambezeleka okusebenzayo kanye nezindleko ezingezekile ezihambisana nokungazinzi kwe-borehole.

4. Ukuvinjwa Kwe-Corosion

I-Petroleum Ibanga CMC-LV ingadlala neqhaza ekuvinjelweni kwe-Cororing. Ngokulawula ukulahleka koketshezi futhi kugcinwe imvelo ezinzile ngaphakathi komthombo, i-CMC-LV isiza ukuvikela imishini yokushayela kusuka ezintweni ezilimazayo ezikhona ekwakhiweni noma kwethulwa ngoketshezi oluvuthayo. Lokhu kunweba isikhathi sokuphila kwemishini yokumba futhi kunciphise izindleko zokulungisa.

Izinzuzo Zokusebenzisa Petroleum Ibanga CMC-LV

1. Ukusebenza kahle kokusebenza

Ukusetshenziswa kwe-CMC-LV ku-drive fluids kuthuthukisa kakhulu ukusebenza kahle. Ukubonakala kwayo okuphansi kuqinisekisa ukuthi uketshezi luhlala luyalawuleka futhi lusebenza kahle ezimweni ezahlukahlukene zokumba, lula ukusebenza okubushelelezi kanye nokunciphisa isikhathi sokuphumula.

2. Ukusebenza kwezindleko

Ngokuvimbela ukulahleka koketshezi kanye nokugcina ukuqina kwe-Wellbore, i-CMC-LV isiza ukunciphisa isikhathi esingakhiqizi kanye nezindleko ezihambisanayo. Kwehlisa isidingo sezinto ezingezekile kanye nokungenelela ukubhekana nokulahleka koketshezi noma ukungazinzi kwe-borehole, okuholela ekugcinweni kwezindleko jikelele.

3. Umthelela Wezemvelo

I-Petroleum Ibanga CMC-LV isuselwa ku-cellulose, insiza yemvelo nevuselelekayo. Ukusetshenziswa kwayo ku-drive fluid kungaba nomthelela emikhubeni yokumba enobungane kakhulu emvelweni. Ngaphezu kwalokho, ukulawulwa kokulahlekelwa ngoketshezi okusebenzayo kunciphisa amandla okungcoliswa kwemvelo kusuka ekudleni uketshezi olungena ekwakhiweni.

4. Ukuphepha okuthuthukile

Ukugcina ukuqina kwe-Wellbore nokulawula ukulahlekelwa koketshezi kubalulekile ekusebenzeni okuphephile kokumba. I-CMC-LV isiza ukuvikela ama-blowaut, ukuwa kahle, nezinye izimo eziyingozi, ukuqinisekisa ukuphepha kwabasebenzi nemishini.

Izicelo ezidlula ukumba uketshezi

Ngenkathi ukusetshenziswa okuyisisekelo kwe-petroleum grade CMC-LV ku-drive fluids, kunezinye izindlela ngaphakathi komkhakha kaphethiloli nangale kwalokho.

1. Ukusebenza kokonga

Ku-Cecleting Operations, i-CMC-LV ingasetshenziswa ukuguqula izakhiwo zezihlamba zikamasipala. Kuyasiza ukulawula ukulahleka kwamanzi uketshezi futhi kuthuthukise izakhiwo zesimbozo se-slurry, kuqinisekise umsebenzi osebenza ngempumelelo futhi ohlala isikhathi eside.

2. Ukuvuselela uwoyela okuthuthukisiwe (eor)

I-CMC-LV ingasetshenziswa ngamasu okuvuselela amafutha athuthukisiwe, lapho izakhiwo zayo zisiza ukuthuthukisa ukuhamba kwamanzi okufakwayo, okwenza ngcono ukusebenza kwenqubo yokubuyisa.

3. Ukuphupha kwe-hydraulic

E-Hydraulic FractHing, i-CMC-LV ingaba yingxenye yokwakhiwa koketshezi, lapho kusiza khona ukulawula ukulahleka koketshezi futhi kugcinwe ukuqina kokuqhekeka okwenziwe.

I-Petroleum Ibanga le-CMC-LV ingamakhemikhali ahlukahlukene futhi abalulekile embonini kawoyela negesi, esetshenziswa ngokuyinhloko ku-drive fluid ukuze uthuthukise ukusebenza kahle, ukuphepha, kanye nokusimama kwemvelo. Izakhiwo zayo ezihlukile, njengokubona okuphansi, i-solubeni eliphakeme, nokuqina okushisayo, kwenze kube nzima ukulawulwa kokulahlekelwa koketshezi, ukuqina kwe-borehole nokuvinjwa kokugqwala. Ngaphandle koketshezi lokugaya, izicelo zalo ekuvumeni kwamafutha, ukulungiswa kwamafutha, kanye nokuphupha kwe-hydraulic kugcizelela ukubaluleka kwayo. Njengoba imboni iqhubeka nokufuna izixazululo ezisebenza kahle nezinemvelo, iqhaza le-Petroleum Ibanga CMC-LV kungenzeka likhule, lifaka isikhundla salo njengengxenye ebalulekile ekwenziweni kobunjiniyela be-petroleum banamuhla.
