Polyanionic Cellulose (PAC) ndi chochokera m'madzi chosungunuka cha cellulose chomwe chimagwiritsidwa ntchito kwambiri pobowola mafuta, makamaka pokonza pobowola madzimadzi. Chakhala chowonjezera chofunikira pakubowola madzimadzi chifukwa cha zinthu zake zapamwamba, monga kukulitsa kukhuthala, kuchepetsa kutaya kwamadzimadzi, kukhazikika komanso kuteteza chilengedwe.
1. Chepetsani kutaya madzimadzi
Kuwongolera kutaya kwamadzi ndi ntchito yofunika kwambiri pakubowola mafuta. Pamene pobowola madzimadzi kukhudzana mapangidwe pa kubowola ndondomeko, zingachititse matope mapangidwe keke ndi kusefera kuwukira mu mapangidwe, kuchititsa kuwonongeka mapangidwe ndi kumakhudza pobowola dzuwa. PAC imachepetsa kutayika kwamadzimadzi komanso kusefera kulowa mu mapangidwe ndikupanga filimu yoteteza mumadzi obowola, potero kuchepetsa kuipitsidwa kwa mapangidwe. Katunduyu amathandizira kukhazikika kwa chitsime komanso kuteteza mapangidwe amafuta ndi gasi.
Mfundo yofunika
PAC imasungunuka m'madzi kuti ipange njira yothetsera colloidal yokhala ndi kukhuthala kwakukulu. Pamene pobowola madzimadzi kulankhula mapangidwe, ndi mamolekyu PAC akhoza kupanga wandiweyani matope keke padziko mapangidwe kuteteza zina malowedwe a madzi gawo. Keke yamatope iyi imakhala ndi kusinthasintha kwabwino komanso kulimba, ndipo imatha kupirira kusiyana kwakukulu, potero imachepetsa kutayika kwa kusefera.
2. Kuonjezera mamasukidwe akayendedwe a pobowola madzimadzi
Kukwezeleza mamasukidwe akayendedwe ndi ntchito ina yofunika ya PAC pobowola madzimadzi. Kubowola madzimadzi ayenera kukhala ndi mamasukidwe akayendedwe ena kunyamula cuttings mmbuyo, kuti kuonetsetsa ukhondo wa chitsime ndi kusunga bata pobowola. Monga mamasukidwe akayendedwe enhancer, PAC akhoza kuonjezera mamasukidwe akayendedwe a pobowola madzimadzi, kumapangitsanso luso pobowola madzimadzi kunyamula cuttings, ndi kulimbikitsa kubwerera ndi kutulutsa cuttings.
Mfundo yofunika
Mamolekyu a PAC amasungunuka mumadzimadzi obowola kuti apange polima unyolo, zomwe zimawonjezera kukana kwamkati kwamadzimadzi. Kapangidwe kameneka kakhoza kuonjezera kukhuthala koonekera ndi kutulutsa mtengo wamadzimadzi obowola, ndikuwonjezera luso lake lonyamula ndi kuyimitsa zodula. Pa nthawi yomweyo, mamasukidwe akayendedwe kuwongola zotsatira za PAC akadali ogwira pansi kutentha ndi mkulu mavuto mikhalidwe, ndipo ndi oyenera pobowola bwino bwino ndi zovuta nthaka mikhalidwe.
3. Sinthani kukhazikika kwa chitsime
Kukhazikika kwa Wellbore ndi nkhani yomwe imafunikira chidwi chapadera pakubowola. Madzi obowola azitha kukhazikika pakhoma la pachitsime kuti khoma la pachitsime lisagwe. Zotsatira zophatikiza za PAC zochepetsera kusefera ndikuwonjezera kukhuthala pakubowola madzimadzi zimatha kupititsa patsogolo kukhazikika kwa Wellbore.
Mfundo yofunika
PAC imalepheretsa madzi obowola kuti asalowe m'mapangidwewo popanga keke yolimba yamatope pamwamba pa khoma la chitsime. Pa nthawi yomweyo, mamasukidwe akayendedwe ake kumapangitsanso adhesion wa bwino khoma pamwamba ndi kuchepetsa m'badwo wa microcracks mu mapangidwe, potero kuwongolera mawotchi bata chitsime. Komanso, PAC akhoza kusintha thixotropy wa pobowola madzimadzi, kuti ndipamene amphamvu thandizo mphamvu pamene ali osasunthika, ndipo amasunga yoyenera fluidity pamene umayenda, zina kukhazikika bwino khoma.
4. Makhalidwe oteteza chilengedwe
Ndikusintha kwachitetezo cha chilengedwe, mankhwala omwe amagwiritsidwa ntchito pobowola madzi amayenera kukhala ndi ntchito yabwino yoteteza chilengedwe. PAC ndi chinthu chosinthidwa cha cellulose yachilengedwe, yokhala ndi biodegradability yabwino komanso kawopsedwe kakang'ono, komwe kamakwaniritsa zofunikira zoteteza chilengedwe.
Mfundo yofunika
PAC ndi chinthu chosinthidwa ndi mankhwala kutengera cellulose yachilengedwe, ilibe zinthu zapoizoni, ndipo imatha kuwonongedwa ndi tizilombo tating'onoting'ono tachilengedwe. Poyerekeza ndi ma polima opangira, PAC ilibe mphamvu zochepa pa chilengedwe ndipo imagwirizana kwambiri ndi zofunikira pakubowola kobiriwira. Khalidweli limapereka mwayi wowonekera bwino m'malo okhudzidwa ndi chilengedwe komanso pobowola m'mphepete mwa nyanja.
5. Kutentha ndi kukana mchere
M'malo otentha kwambiri komanso amchere wambiri, dongo lachikhalidwe ndi ma polima nthawi zambiri zimakhala zovuta kusunga kukhazikika kwamadzi obowola, pomwe PAC imawonetsa kutentha kwabwino komanso kukana mchere ndipo imatha kukhalabe ndi mphamvu yamadzi akubowola m'malo ovuta.
Mfundo yofunika
Magulu a anionic (monga magulu a carboxyl) amalowetsedwa m'maselo a PAC. Maguluwa amatha kusinthanitsa ma ions ndi ayoni amchere m'malo amchere kwambiri kuti asunge bata la kapangidwe ka maselo. Pa nthawi yomweyo, PAC ali mkulu matenthedwe bata ndipo sadzakumana kwambiri kuwonongeka pansi pa mikhalidwe kutentha, kuonetsetsa mamasukidwe akayendedwe ndi kusefera kulamulira mphamvu ya madzimadzi pobowola. Chifukwa chake, PAC imakhala ndi zotsatira zabwino kwambiri pakugwiritsa ntchito madzi amchere amchere ndi zitsime zotentha kwambiri.
6. Konzani pobowola madzimadzi rheology
Rheology imatanthawuza mawonekedwe akuyenda ndi kupunduka kwamadzi akubowola pansi pa mphamvu yakumeta ubweya. PAC imatha kusintha rheology yamadzi akubowola kuti atsimikizire kuti ali ndi mphamvu yabwino yonyamula miyala ndipo amatha kuyenda momasuka m'chitsime pobowola.
Mfundo yofunika
PAC interacts ndi zigawo zina mu pobowola madzimadzi kupanga zovuta maukonde dongosolo ndi kusintha zokolola mtengo ndi kukameta ubweya kupatulira makhalidwe a pobowola madzimadzi. Kuwongolera kumeneku kumathandizira kuti madzi akubowola awonetse mphamvu yonyamula miyala yabwino komanso madzimadzi panthawi yobowola, makamaka m'mapangidwe ovuta komanso zitsime zothamanga kwambiri.
7. Kusanthula nkhani
Pochita ntchito, PAC imagwiritsidwa ntchito kwambiri pamakina osiyanasiyana obowola madzimadzi. Mwachitsanzo, pobowola chitsime chakuya, madzi obowola opangidwa ndi madzi okhala ndi PAC adagwiritsidwa ntchito. Zotsatira zinasonyeza kuti PAC inachepetsa kwambiri kusefa kwa madzi obowola, kumapangitsa kuti chitsimecho chikhale chokhazikika, chibowola bwino, komanso kuchepetsa ngozi zapabowo zomwe zimachitika chifukwa cha kuwonongeka kwa mapangidwe. Panthawi imodzimodziyo, PAC inachitanso bwino pobowola m'madzi, ndipo imatha kuyendetsa bwino ntchito yamadzimadzi obowola pansi pa mchere wambiri komanso kutentha kwambiri kuti zitsimikizire kuti ntchito yobowola ikuyenda bwino.
Kugwiritsa ntchito cellulose ya polyanionic pakubowola mafuta kumawonekera makamaka mumikhalidwe yake yabwino kwambiri yochepetsera kutayika kwa kusefera, kukulitsa kukhuthala, kuwongolera kukhazikika kwabwino komanso kuteteza chilengedwe. Kugwiritsa ntchito kwake m'madzi opangira madzi komanso opangira mafuta sikungowonjezera bwino pakubowola komanso kumachepetsa ngozi zapamadzi, komanso kumathandizira kuti pakhale chilengedwe komanso kumathandizira kukwaniritsa cholinga choboola zobiriwira. Pansi pazovuta za geological komanso kutentha kwambiri komanso kupanikizika kwambiri, kutentha kwa PAC ndi kukana mchere kumawonetsanso kufunikira kwake pakubowola mafuta. Chifukwa chake, cellulose ya polyanionic imakhala ndi malo ofunikira muukadaulo wamakono wobowola mafuta.
