Ukuthuthukiswa kwe-Oilfield kuyinqubo eyinkimbinkimbi ebandakanya izinyathelo eziningi, okuhlanganisa ukuhlola, ukumba, ukuqeda, ukukhiqiza, nokulahlwa. Phakathi kwalezi zinyathelo, imisebenzi yokumba ibaluleke kakhulu njengoba ithinta ngqo ukusebenza kahle nokuphepha kokukhipha uwoyela negesi. I-Barium sulfate, njenge-ejenti enesisindo, idlala indima ebalulekile ekulungiseni uketshezi lwamanzi, ikakhulukazi ekugezeni imithombo ejulile neyinkimbinkimbi.
Uketshezi lokumba luwuketshezi olubalulekile ekusebenzeni kokumba, olungagcini nje ngokusetshenziselwa ukupholisa izingcezu zokubhoboza nokuthwala okusikiwe kwamadwala kubuyiselwe phezulu, kodwa futhi nokugcina ibhalansi yokucindezela ngaphansi komhlaba. Emgodini ojulile, njengoba ukujula komthombo kukhula, ingcindezi engaphansi komhlaba nayo izokhula ngokufanayo. Ukuze kugcinwe ibhalansi yokucindezela ngaphansi komhlaba, ukuvimbela ukuhlasela kwamanzi okwakheka kanye nokuvela kwezingozi zokuqhuma, kuyadingeka ukwandisa ukuminyana koketshezi lokumba. I-Barium sulfate ngenxa yokuminyana kwayo okuphezulu (4.25-4.5 g/cm) ³ ） Ngokuzinza okuhle kwamakhemikhali, kuyisinqumo esihle sokwandisa ukuminyana koketshezi lokumba.
Ukuminyana okuphezulu: Izakhiwo eziphakeme kakhulu ze-barium sulfate ziyenza ikwazi ukukhulisa kahle ukuminyana koketshezi lokumba, ukuhlangabezana nezidingo zokumba imithombo ejulile kanye nemithombo yomfutho ophezulu kawoyela negesi.
Ukuzinza kwamakhemikhali: I-Barium sulfate ihlala izinzile ekushiseni okuphezulu nasezindaweni ezicindezelayo futhi ayijwayele ukusabela kwamakhemikhali, okuvumela ukuthi isebenze ngisho nangaphansi kwezimo ezimbi kakhulu ze-downhole.
I-solubility ephansi: I-Barium sulfate icishe ingancibiliki emanzini nasezincibilikisini eziningi, okusho ukuthi ngeke incibilike oketshezini lokumba, iqinisekise ukuzinza nokusebenza kwayo.
Ivumelana nemvelo: Uma iqhathaniswa namanye ama-ejenti ashubisayo angase abangele ukungcoliswa kwemvelo, i-barium sulfate inomthelela omncane kwezemvelo futhi isiza ekuthuthukisweni okusimeme kokuthuthukiswa kwendawo kawoyela.
I-ejenti yokulinganisa uketshezi lokumba: I-Barium sulfate ingaxutshwa namanzi ukuze yakhe uketshezi lokumba olunomthamo omkhulu, olusetshenziselwa ukumba imithombo ejulile kanye nemithombo kawoyela negesi enengcindezi ephezulu.
Ukulawula ukucindezela kwe-Downhole: I-Barium sulfate isiza ukugcina ibhalansi yengcindezi ngaphansi komhlaba, ivimbele ukuhlasela koketshezi okwakheka kanye nokuvela kwezingozi zokuqhuma.
Ukuthuthukisa ukusebenza kahle kokumba: Ukusetshenziswa kwe-barium sulfate kunganciphisa inkimbinkimbi yenqubo yokumba, kuthuthukise ukusebenza kahle kokumba kanye nokubuyiswa kukawoyela negesi.
Ukuvikelwa kwemvelo: Ukusetshenziswa kwe-barium sulfate kunciphisa ukungcola okungenzeka emvelweni futhi kusiza ukufeza imigomo yokuvikela imvelo yokuthuthukiswa kwendawo yamafutha.
Uma usebenzisa i-barium sulfate njenge-ejenti enesisindo ekuthuthukisweni kwendawo kawoyela, kuyadingeka futhi ukucabangela umthelela ongaba khona emvelweni futhi uthathe izinyathelo ezihambisanayo zokuvikela imvelo. Isibonelo, kufanele kuqinisekiswe ukuthi ukusetshenziswa kwe-barium sulfate akubangeli ukungcola emanzini azungezile, futhi ngemva kokusebenza kokumba, imfucuza equkethe i-barium sulfate kufanele ilahlwe ngendlela efanele ukuze kugwenywe ukungcoliswa kwemithombo yomhlabathi namanzi angaphansi komhlaba.
Ukusetshenziswa kwe-barium sulfate ekuthuthukisweni kwendawo kawoyela kunezinzuzo ezibalulekile, njengoba ukuminyana kwayo okuphezulu, ukuzinza kwamakhemikhali, kanye nobungane bemvelo kukwenza kube ukukhetha okuhle kokumba ama-agent okulinganisa uketshezi. Ngokuqhubeka okuqhubekayo kobuchwepheshe bokuthuthukiswa kwe-oilfield kanye nokuthuthukiswa kwezidingo zokuvikela imvelo, ukusetshenziswa kwe-barium sulfate kuzoba okubanzi nokujulile. Ngokuzayo, indima ye-barium sulfate ekuthuthukisweni kwendawo kawoyela izoqhubeka nokuthuthukiswa, kube neqhaza elikhulu ekukhishweni okusebenzayo, okuphephile, nokunobungani kwemvelo kwemithombo kawoyela negesi.
