Hydroxyethyl Cellulose (HEC) ndi polima wosungunuka m'madzi womwe umagwiritsidwa ntchito kwambiri pobowola mafuta. Maonekedwe ake apadera akuthupi ndi mankhwala amamupatsa maubwino angapo pankhaniyi.
1. Kusintha kwa rheological properties
Ma cellulose a Hydroxyethyl ali ndi zinthu zokhuthala bwino ndipo amatha kuwonjezera kukhuthala kwamadzi obowola. Katunduyu ndi wofunikira kwambiri pakubowola, chifukwa madzi obowola okwera kwambiri amatha kuyimitsa kudula ndikuletsa kuyika pansi pa chitsime kapena pakhoma la chitoliro, potero kumathandizira pobowola bwino komanso chitetezo. Khalidwe la pseudoplastic la mayankho a HEC limapangitsa kuti pakhale kukhuthala kocheperako pamitengo yayikulu yometa ubweya (monga pafupi ndi pobowola), zomwe zimachepetsa kukangana ndi kupopera mphamvu, komanso kukhuthala kwapamwamba pamiyeso yotsika (monga pafupi ndi khoma la chitsime), zomwe zimathandiza Kunyamula ndi kuyimitsa kubowola cuttings.
2. Kuthira madzi ndi kusunga madzi
Ma cellulose a Hydroxyethyl ali ndi zinthu zabwino kwambiri za hydration ndipo amatha kusungunuka m'madzi ndikupanga njira yofananira. Kuchita uku kumathandizira kukonzekera mwachangu ndikusintha kwamadzimadzi obowola pamalowo, ndikuwonjezera kusinthasintha kwa magwiridwe antchito. Kuphatikiza apo, HEC imakhalanso ndi mphamvu zosungira madzi, zomwe zingathe kuchepetsa kutuluka kwa nthunzi ndi kutaya madzi mumadzi obowola ndikusunga bata ndi mphamvu zamadzimadzi obowola. Makamaka m'malo otentha komanso othamanga kwambiri, malo ake osungira madzi ndi ofunika kwambiri.
3. Kuwongolera kwa fyuluta
Pa kubowola ndondomeko, kutaya madzimadzi a pobowola madzimadzi ndi yofunika chizindikiro. Kuwonongeka kwakukulu kwa kusefera kumabweretsa kuwonjezeka kwa makulidwe a keke yamatope, zomwe zingayambitse mavuto monga kusakhazikika kwa khoma komanso kutayikira bwino. Ma cellulose a Hydroxyethyl amatha kuchepetsa kutayika kwamadzimadzi obowola, kupanga keke wandiweyani, kuchepetsa chiopsezo cha kutayikira ndi kugwa kwa khoma la chitsime, ndikupangitsa kuti khoma la chitsime likhale lokhazikika. Kuphatikiza apo, HEC imatha kukhalabe yokhazikika pansi pamitundu yosiyanasiyana ya pH ndi mikhalidwe yolumikizira ma electrolyte ndikusinthira kuzinthu zosiyanasiyana zovuta.
4. Eco-ochezeka
Pamene malamulo a chilengedwe akuchulukirachulukira, kufunikira kwa madzi obowola otetezedwa ndi chilengedwe kukuchulukiranso. Monga chochokera ku cellulose yachilengedwe, hydroxyethyl cellulose imakhala ndi biodegradability yabwino ndipo ilibe mphamvu zochepa pa chilengedwe. Poyerekeza ndi ma polima ena opangidwa, kugwiritsa ntchito HEC kumachepetsa mpweya woipa ndikuthandizira kukwaniritsa zolinga zoboola zobiriwira. Kuonjezera apo, chikhalidwe chopanda poizoni komanso chosavulaza cha HEC chimachepetsanso zoopsa zomwe zingakhalepo kwa ogwira ntchito zaumoyo.
5. Zachuma
Ngakhale mtengo wa hydroxyethyl cellulose ndi wokwera kwambiri, ntchito yake yabwino kwambiri ikagwiritsidwa ntchito imatha kuchepetsa mtengo wonse pakubowola. Choyamba, kukhuthala bwino kwa HEC ndikusunga madzi kumachepetsa kuchuluka kwamadzi obowola komanso mtengo wazinthu. Kachiwiri, kukhazikika ndi kudalirika kwa HEC kumachepetsa chiopsezo cha kulephera kwapansi pansi ndi kutsekedwa kosakonzekera, kuchepetsa ndalama zokonzekera ndi kukonza. Pomaliza, katundu wa HEC wokonda zachilengedwe amachepetsa ndalama zotayira zinyalala komanso kutsata chilengedwe.
6. Kugwirizana ndi Kusinthasintha
Ma cellulose a Hydroxyethyl ali ndi kukhazikika kwamankhwala abwino komanso kuyanjana kwakukulu, ndipo amatha kukhala ogwirizana ndi zowonjezera zosiyanasiyana ndi makina obowola madzimadzi kuti apange dongosolo lophatikizika ndi ntchito zenizeni. Mwachitsanzo, HEC ikhoza kugwiritsidwa ntchito limodzi ndi anti-collapse agents, anti-Leak agents ndi mafuta odzola kuti apititse patsogolo ntchito zonse zamadzimadzi obowola ndikukwaniritsa mikhalidwe yosiyanasiyana ya nthaka ndi zosowa zoboola. Kuonjezera apo, HEC ingagwiritsidwenso ntchito mu mankhwala ena opangira mafuta monga kutsirizitsa madzi ndi fracturing fluid, kusonyeza kusinthasintha kwake.
Ma cellulose a Hydroxyethyl ali ndi zabwino zambiri pakubowola mafuta, zomwe zimawonetsedwa makamaka pakuwongolera ma rheological properties, kuwonjezera mphamvu ya hydration ndi kusunga madzi, kuwongolera bwino kusefera, kukhala wokonda zachilengedwe, ndalama komanso ntchito zambiri. Ubwinowu umapangitsa HEC kukhala chowonjezera chofunikira komanso chofunikira pakubowola mafuta, kuthandiza kukwaniritsa ntchito zobowola bwino, zotetezeka komanso zachilengedwe. Ndi kupita patsogolo kosalekeza kwaukadaulo komanso kuzama kwa kagwiritsidwe ntchito, chiyembekezo chogwiritsa ntchito hydroxyethyl cellulose pakubowola mafuta chidzakhala chokulirapo.
