I-Petroleum Grade Carboxymethyl Cellulose (CMC) iyikhemikhali ebalulekile esetshenziswa embonini kawoyela negesi, ikakhulukazi oketshezini lokumba. Igama elithi “LV” limele “Low Viscosity,” okubonisa izakhiwo zayo ezithile ezibonakalayo nokufaneleka kwezinhlelo ezithile zokusebenza ngaphakathi kokukhipha nokucutshungulwa kwe-petroleum.
Ukubunjwa kanye Nezakhiwo ze-Petroleum Grade CMC-LV
I-Carboxymethyl Cellulose i-polymer encibilika emanzini etholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. Ukuhluka "kwe-viscosity ephansi" kunezici eziyingqayizivele, kufaka phakathi isisindo esiphansi samangqamuzana, esihumusha emthonjeni ophansi wokuqina lapho kuncibilika emanzini. Lokhu kuyenza ilungele izinhlelo zokusebenza ezidinga ushintsho oluncane ku-viscosity yoketshezi.
Izici Eziyinhloko:
Ukunyibilika: Ukuncibilika okuphezulu emanzini, okwenza kube lula ukuxutshwa nokusabalalisa ngaphakathi koketshezi lokumba.
Ukuzinza Kwe-Thermal: Igcina ubuqotho bokusebenza ngaphansi kwamazinga okushisa aphezulu okuhlangatshezwana nawo ngesikhathi sokumba.
Ukubekezelela i-pH: Izinzile emazingeni ahlukahlukene e-pH, okuyenza isebenze ngezindlela eziningi ezindaweni ezahlukene zokumba.
I-Viscosity Ephansi: Umthelela omncane ku-viscosity yoketshezi oluyisisekelo, olubalulekile ezimweni ezithile zokumba.
Ukusetshenziswa kwe-Petroleum Grade CMC-LV
1. Drilling Fluids
Ukusetshenziswa okuyinhloko kwe-Petroleum Grade CMC-LV kusekwenzeni uketshezi lokumba, olubuye lwaziwe njengodaka. Lawa manzi abalulekile enqubweni yokumba ngezizathu ezimbalwa:
Ukuthambisa: Uketshezi lokumba lugcoba i-drill bit, lunciphisa ukungqubuzana nokuguga.
Ukupholisa: Basiza ukupholisa i-drill bit kanye nentambo yokubhoboza, ukuvimbela ukushisa ngokweqile.
Ukulawula Ukucindezela: Uketshezi lokumba luhlinzeka ngomfutho we-hydrostatic ukuvimbela ukuqhunyiswa kanye nokuzinzisa umthombo.
Ukususwa kwe-Cuttings: Bahambisa i-drill cuttings phezulu, igcina indlela ecacile yokubhoboza.
Kulo mongo, i-viscosity ephansi ye-CMC-LV iqinisekisa ukuthi uketshezi lokumba luhlala lumpompa futhi lungakwazi ukwenza le misebenzi ngempumelelo ngaphandle kokuba lushube kakhulu noma lube ne-gelatinous, olungase luthiye ukuhambahamba nokusebenza kahle kokubhola.
2. Ukulawula Ukulahlekelwa Uketshezi
Ukulawulwa kokulahlekelwa uketshezi kubalulekile emisebenzini yokumba ukuze kuvinjwe ukulahlekelwa uketshezi lokumba ekubunjweni kwalo. I-Petroleum Grade CMC-LV isebenza njenge-ejenti yokulawula ukulahlekelwa uketshezi ngokwenza ikhekhe lesihlungi elincanyana, elingakwazi ukungena kalula ezindongeni zomthombo. Lesi sithiyo sinciphisa ukungena koketshezi lokumba ekwakhekeni kwamadwala azungezile, ngaleyo ndlela kugcinwe ubuqotho bomthombo futhi kuvimbele ukulimala okungase kube khona ukwakheka.
3. Ukuthuthukisa Ukuzinza Kwemigodi
Ngokufaka isandla ekwakhiweni kwekhekhe lokuhlunga elizinzile, i-CMC-LV isiza ekugcineni ukuqina kwemigodi. Lokhu kubaluleke kakhulu ekwakhekeni okujwayele ukungazinzi noma ukuwa. Ikhekhe lesihlungi lisekela izindonga zomthombo futhi livimbela ukushelela noma ukugoba, linciphisa ingozi yokubambezeleka kokusebenza kanye nezindleko ezengeziwe ezihambisana nokungaqini kwemigodi.
4. Ukuvimbela Ukugqwala
I-Petroleum Grade CMC-LV nayo ingadlala indima ekuvimbeleni ukugqwala. Ngokulawula ukulahleka koketshezi kanye nokugcina indawo ezinzile ngaphakathi komthombo, i-CMC-LV isiza ukuvikela okokusebenza kokumba ezintweni ezibolayo ezikhona ekubunjweni noma ezethulwa ngoketshezi lokumba. Lokhu kwandisa isikhathi sokuphila kwemishini yokumba futhi kunciphisa izindleko zokuyilungisa.
Izinzuzo Zokusebenzisa Ibanga Le-Petroleum CMC-LV
1. Ukusebenza Ngempumelelo
Ukusetshenziswa kwe-CMC-LV kuketshezi lokumba kuthuthukisa kakhulu ukusebenza kahle. I-viscosity yayo ephansi iqinisekisa ukuthi uketshezi luhlala lulawuleka futhi lusebenza kahle ezimweni ezihlukahlukene zokumba, lula ukusebenza okushelelayo nokunciphisa isikhathi sokuphumula.
2. Ukusebenza Kwezindleko
Ngokuvimbela ukulahleka koketshezi kanye nokugcina uzinzo lwe-wellbore, i-CMC-LV isiza ukunciphisa isikhathi esingakhiqizi kanye nezindleko ezihambisanayo. Yehlisa isidingo sezinto ezengeziwe kanye nokungenelela ukuze kubhekwane nokulahlekelwa uketshezi noma ukungazinzi kwe-borehole, okuholela ekongeni kwezindleko zizonke.
3. Umthelela Wezemvelo
I-Petroleum Grade CMC-LV isuselwa ku-cellulose, insiza yemvelo nevuselelekayo. Ukusetshenziswa kwawo ekumba izinto eziwuketshezi kungaba nomthelela emikhubeni yokumba ehambisana nemvelo. Ukwengeza, ukulawulwa okusebenzayo kokulahlekelwa uketshezi kunciphisa amandla okungcoliswa kwemvelo kusuka kuketshezi lokumba olungena ekubunjweni.
4. Ukuphepha Okuthuthukisiwe
Ukugcina ukuqina kwe-wellbore nokulawula ukulahlekelwa uketshezi kubalulekile ekusebenzeni okuphephile kokumba. I-CMC-LV isiza ekuvimbeleni ukuqhuma, ukuwa kwemithombo yamanzi, nezinye izimo eziyingozi, iqinisekisa ukuphepha kwabasebenzi nezisetshenziswa.
Izicelo Ngaphandle Kokubhoboza Uketshezi
Nakuba ukusetshenziswa okuyinhloko kwe-Petroleum Grade CMC-LV kusekuketshezini kokumba, inokunye ukusetshenziswa embonini ye-petroleum nangale kwayo.
1. Imisebenzi Yokuqinisa
Emisebenzini yokufaka usimende, i-CMC-LV ingasetshenziselwa ukuguqula izakhiwo zamaslurry usimende. Isiza ukulawula ukulahlekelwa kwamanzi futhi ithuthukise izakhiwo ze-rheological ze-slurry, iqinisekise umsebenzi osebenza kahle futhi ohlala njalo we-cement.
2. Ukutholwa Kawoyela Okuthuthukisiwe (EOR)
I-CMC-LV ingasetshenziswa kumasu Athuthukisiwe Wokubuyisela Uwoyela, lapho izakhiwo zayo zisiza ukuthuthukisa ukuhamba koketshezi olujovwe, kuthuthukise ukusebenza kahle kwenqubo yokutakula.
3. I-Hydraulic Fracturing
Ku-hydraulic fracturing, i-CMC-LV ingaba yingxenye yokwakheka koketshezi oluqhekekayo, lapho isiza khona ukulawula ukulahleka koketshezi nokugcina ukuzinza kokuqhekeka okudaliwe.
I-Petroleum Grade CMC-LV iyikhemikhali eguquguqukayo nebalulekile embonini kawoyela negesi, esetshenziswa ngokuyinhloko ekumbeni uketshezi ukuze kuthuthukiswe ukusebenza kahle, ukuphepha, nokusimama kwemvelo. Izakhiwo zayo eziyingqayizivele, ezifana ne-viscosity ephansi, ukuncibilika okuphezulu, nokuzinza kokushisa, kuyenza ibaluleke kakhulu ekulawuleni ukulahlekelwa uketshezi, ukuzinza kwe-borehole, kanye nokuvimbela ukugqwala. Ngaphandle koketshezi lokumba, ukusetshenziswa kwayo ekufakeni usimende, ukutholwa kabusha kukawoyela okuthuthukisiwe, kanye ne-hydraulic fracturing kugcizelela ukubaluleka kwayo. Njengoba imboni iqhubeka nokufuna izixazululo ezisebenza kahle nezinobungani kwemvelo, indima ye-Petroleum Grade CMC-LV cishe izokhula, iqinise isikhundla sayo njengengxenye ebalulekile emisebenzini yesimanje yobunjiniyela be-petroleum.
