Mu makampani opanga mafuta ndi gasi padziko lonse lapansi, kufunafuna ntchito zobowola bwino ndi ntchito yopitilira, ndipo madzi obowola abwino kwambiri amatenga gawo lofunikira pakusunga bata la wellboord, kuziziritsa zidutswa zobowola, ndikunyamula zidutswazo pamwamba. Ufa wa Bentonite, makamaka bentonite wokhala ndi sodium wochuluka mu montmorillonite, waonekera ngati chinthu chofunikira kwambiri popanga madzi obowola. Mphamvu yake yodabwitsa yodzaza ndi madzi, mphamvu zake za thixotropic, komanso kuthekera kopanga keke yofewa komanso yopepuka yolowera madzi zimapangitsa kuti ikhale yofunika kwambiri pantchito zamakono zobowola.

Pa kuboola zitsime zakuya, komwe kutentha kwa pansi kumatha kukwera mpaka 150-200°C ndipo kupanikizika kumapitirira 30 MPa, kukhazikika kwa madzi oboola kumakhala chinthu chofunikira kwambiri. Zowonjezera zamadzi oboola nthawi zambiri zimalephera pansi pamikhalidwe yovuta kwambiri, koma ufa wa bentonite wochokera ku sodium umadziwika ndi mphamvu zake zabwino kwambiri za rheological. Mu malo akuluakulu ofukula mafuta ku Middle East, mayeso oyerekeza adawonetsa kupambana kwa madzi oboola okhala ndi ufa wathu wa bentonite wochokera ku sodium. Liwiro lapakati la kuboola linakwera ndi 18%, ndipo kuchuluka kwa zochitika zogwa kwa zitsime kunachepa ndi 70% poyerekeza ndi zowonjezera zadothi wamba. Kupambana kumeneku kungachitike chifukwa cha montmorillonite mu ufa wa bentonite, womwe umapanga keke yofanana yosefera, yomwe nthawi zambiri imakhala 1-3 mm wandiweyani, pakhoma la chitsime. Keke yosefera iyi imachepetsa kutayika kwa madzi ku mapangidwe, ndi mitengo yotayika ya fyuluta ≤10 mL/30 mphindi pansi pa mikhalidwe yokhazikika ya API, potero imaletsa kuwonongeka kwa mapangidwe.

Kuwonjezera pa bentonite yochokera ku sodium, zinthu zathu zimaphatikizapo ufa wa bentonite wochokera ku calcium, womwe ndi woyenera kwambiri kuboola zitsime zosaya kwambiri komanso kuboola madzi abwino. Ngakhale bentonite yochokera ku calcium ili ndi mphamvu yotupa yochepa poyerekeza ndi yochokera ku sodium, imapereka ndalama zabwino kwambiri. Ikachiritsidwa ndi sodium carbonate, yomwe ndi activator wamba, bentonite yochokera ku calcium imatha kusinthidwa kukhala sodium-calcium mixed bentonite. Kagwiridwe ka bentonite yosakanikirana iyi ndi kofanana ndi ka bentonite yachilengedwe yochokera ku sodium, zomwe zimapangitsa kuti ikhale yoyenera kuboola zinthu mozama, nthawi zambiri kuyambira mamita 1000 mpaka 3000.

Kuwongolera khalidwe ndikofunikira kwambiri popanga ufa wa bentonite wa madzi obowolera. Zogulitsa zathu zimatsatira miyezo yokhwima, ndipo zizindikiro zazikulu zimakwaniritsa zofunikira za API Spec 13A. Miyezo iyi imafotokoza kuchuluka kwa montmorillonite kwa ≥80%, chinyezi cha ≤12%, kuchuluka kwa mchenga kwa ≤2%, ndi zotsalira za sieve ya 325-mesh ya ≤0.5%. Gulu lililonse la zinthu limayesedwa mwamphamvu mu labotale yathu kuti lione ngati zili zokhuthala, kutayika kwa fyuluta, ndi kuchuluka kwa kutupa, ndipo lipoti lonse lowunikira khalidwe limaperekedwa kwa makasitomala athu.

Pofuna kukwaniritsa zosowa zosiyanasiyana za makasitomala amafuta ndi gasi padziko lonse lapansi, timapereka njira zopangira ufa wa bentonite. Pa ntchito zobowola zakunja zomwe zimagwiritsa ntchito madzi a m'nyanja, omwe ali ndi mchere wambiri, timasintha pamwamba pa ufa wa bentonite ndi mchere wa quaternary ammonium. Kusintha kumeneku kumathandizira kwambiri kupirira mchere wa ufa wa bentonite, kuonetsetsa kuti madzi obowola amakhalabe ndi kukhuthala kokhazikika komanso kutayika kochepa kwa fyuluta, ngakhale m'madzi a m'nyanja okhala ndi mchere wa 35‰. M'malo ozizira obowola, komwe kutentha kwa pansi kumatha kutsika kufika ≤0°C, timawonjezera zinthu zoletsa kuzizira ku ufa wa bentonite. Izi zimaletsa madzi obowola kuzizira ndipo zimaonetsetsa kuti kuyenda kwake kumayenda bwino, zomwe zimathandiza ntchito zobowola mosalekeza komanso moyenera.

Ponena za kayendetsedwe ka zinthu, timaika patsogolo umphumphu wa zinthu zathu panthawi yoyendera. Ufa wathu wa bentonite umapakidwa m'matumba osanyowa komanso oletsa kusungidwa, nthawi zambiri 25 kg iliyonse, ndi filimu yamkati ya polyethylene ndi thumba lakunja la pepala lokhala ndi chophimba chosalowa madzi. Phukusili limateteza ufa wa bentonite kuti usayamwe chinyezi panthawi yoyendera panyanja mtunda wautali. Takhazikitsa mgwirizano wamphamvu ndi makampani otsogola otumiza katundu monga Maersk ndi CMA CGM, kuonetsetsa kuti zinthu zathu zitha kutumizidwa ku madoko ku Middle East, Africa, ndi North America mkati mwa masiku 20-35.
