Hydroxyethyl cellulose (HEC) ndi polima yosungunuka m'madzi yopanda ionic yokhala ndi makulidwe abwino kwambiri, kusunga madzi, kukhazikika komanso kudzoza. M'mapulojekiti obowola mafuta, magwiridwe antchito amadzimadzi obowola, madzimadzi omaliza ndi madzimadzi ophwanyidwa amathandizira kwambiri pakubowola bwino komanso kukhazikika kwa khoma. Monga chowonjezera chofunikira pakubowola madzimadzi, HEC yakhala ikugwiritsidwa ntchito kwambiri pobowola mafuta.
Makhalidwe oyambira a hydroxyethyl cellulose
1. Kusungunuka kwamadzi kwabwino: HEC ikhoza kusungunuka mwamsanga m'madzi ozizira kapena otentha kuti apange njira yowonekera yowonekera, yomwe ili yabwino pomanga malo.
2. Makulidwe ndi rheological kusintha luso: HEC akhoza kwambiri kuonjezera mamasukidwe akayendedwe ndi thixotropy wa pobowola madzimadzi, kumapangitsanso thanthwe kunyamula mphamvu pobowola madzimadzi, kuthandiza kunyamula kubowola cuttings, ndi bwino pobowola dzuwa.
3. Kukhazikika kwabwino kwa mchere wosungunuka: HEC ikhoza kukhalabe yosungunuka bwino komanso yokhazikika pansi pa mikhalidwe yambiri ya mineralization, ndipo ndiyoyenera kubowola m'madzi ndi mapangidwe a mchere wambiri.
Mafuta abwino: HEC imatha kuchepetsa kugundana kwamadzimadzi obowola, kuchepetsa kuwonongeka kwa kubowola ndi khoma la chitsime, ndikukulitsa moyo wautumiki wa zida.
4. Kutentha ndi kukameta ubweya wa ubweya: HEC ikhoza kukhalabe ndi kukhuthala kokhazikika pansi pa kutentha kwakukulu ndi kumeta ubweya wambiri, ndipo ndi yoyenera pobowola chitsime chakuya komanso chozama kwambiri.
Kugwiritsa ntchito hydroxyethyl cellulose pobowola mafuta
1. Kubowola madzimadzi thickener
Pobowola, madzi akubowola amagwiritsidwa ntchito kuziziritsa pobowola, kudzoza chitoliro chobowola, kunyamula zodula ndikukhazikitsa khoma lachitsime. The thickening zotsatira za HEC akhoza kuonjezera mamasukidwe akayendedwe ndi kunyamula mphamvu ya madzimadzi pobowola, kotero kuti mogwira kuyimitsa ndi kunyamula cuttings, kuwaletsa waikamo pansi pa chitsime kapena payipi, ndi kukhudza bwino pobowola. Kuphatikiza apo, kukhuthala kwa HEC kumathanso kupititsa patsogolo kumeta ubweya wamadzimadzi ndikuwongolera luso loyeretsa bwino.
2. Kumaliza madzimadzi ndi simenti zowonjezera madzimadzi
Kumaliza kwamadzimadzi kumagwiritsidwa ntchito kuteteza ndikukhazikitsa khoma lachitsime kuti zitsimikizire kuyenda bwino kwamafuta ndi gasi. HEC ingagwiritsidwe ntchito ngati thickener kuti amalizitse madzimadzi kuti apereke kukhuthala koyenera, kupititsa patsogolo luso loyimitsidwa, komanso kupewa kugwa kwa khoma. Panthawi yopangira simenti, zomatira zabwino kwambiri za HEC zimathandizira kugawa matope a simenti mofanana, kupititsa patsogolo luso la simenti, kupititsa patsogolo kukhazikika kwa zigawo za simenti, ndikuchepetsa kutayikira kwamadzimadzi.
3. Fracturing fluid modifier
Hydraulic fracturing ndi njira yodziwika bwino yowonjezera kupanga ndi jekeseni. Fracturing fluid imagwiritsidwa ntchito popanga ma fractures ochita kupanga ndikuwonjezera kutha kwa zitsime zamafuta ndi gasi. Monga thickener kwa fracturing madzimadzi, HEC akhoza kusintha rheological katundu, kuonjezera ductility ndi mchenga kunyamula mphamvu fractures, ndi kuonetsetsa fracturing zotsatira. Kuonjezera apo, kusungunuka kwamadzi kwa HEC kumapangitsa kuti awonongeke mosavuta pakadutsa gel osakaniza popanda kuwononga mapangidwe, zomwe zimathandiza kuti zitsime za mafuta ndi gasi zikhale bwino.
4. Madzi ochepetsa kutaya madzi
Pobowola, kubowola kutayika kwamadzimadzi ndikofunikira kuti mupewe kusakhazikika kwa chitsime komanso kupanga keke yamatope. HEC imatha kuchepetsa kutayika kwamadzi obowola, kuchepetsa kulowa kwamadzimadzi mu mapangidwe, kuteteza kugwa kwa Wellbore, ndikuwongolera chitetezo ndi kukhazikika kwa ntchito zoboola. Makamaka pamapangidwe apamwamba kwambiri, mphamvu ya HEC yowongolera kutaya kwamadzi ndiyofunikira kwambiri, yomwe imathandizira kusunga umphumphu wa Wellbore.
5. Kugwiritsa ntchito pobowola m'mphepete mwa nyanja ndi mapangidwe amchere wambiri
Pobowola m'mphepete mwa nyanja ndi pobowola mchere wambiri, madzi obowola amafunikira kukhala ndi mchere wabwino komanso kusamva calcium. HEC imatha kukhalabe ndi kusungunuka kwabwino komanso kukhazikika pamalo omwe ali ndi mineralization ambiri, omwe amatha kusintha bwino kukana kwa mchere wamadzi obowola ndikuletsa kulephera kwamadzimadzi. Kuphatikiza apo, kuwonongeka kwa biodegradability kwa HEC kumapangitsanso kukhala chowonjezera chokondedwa chamadzi obowola ochezeka ndi chilengedwe.
Hydroxyethyl cellulose imagwira ntchito yofunika kwambiri pakubowola mafuta chifukwa cha kukhuthala kwake, kuchepetsa kusefera, kuthira mafuta komanso kukhazikika. Monga chowonjezera chachikulu chamadzimadzi obowola, madzi omaliza ndi madzi ophwanyidwa, HEC imatha kusintha mawonekedwe amadzimadzi obowola, kuchepetsa kusefera, kukulitsa mphamvu yonyamula miyala, ndikusintha kumadera ovuta monga mchere wambiri, kutentha kwambiri komanso kumeta ubweya wambiri. M'tsogolomu chitukuko cha teknoloji yobowola mafuta, chiyembekezo chogwiritsira ntchito HEC chidzakhala chokulirapo, makamaka pa kafukufuku ndi kugwiritsa ntchito madzi obowola obiriwira komanso oteteza zachilengedwe, HEC ikuyembekezeka kukhala chinthu chofunikira kwambiri chogwira ntchito.
