Chifukwa chiyani CMC ingagwiritsidwe ntchito pobowola mafuta?

Carboxymethyl cellulose (CMC) imagwiritsa ntchito kwambiri pobowola mafuta chifukwa cha mawonekedwe ake apadera omwe amalimbana ndi zovuta zingapo zomwe zimachitika pobowola. Ichi ndichifukwa chake CMC imagwiritsidwa ntchito pobowola mafuta:

1. Fluid Viscosity Control:

Pobowola mafuta, madzi obowola (omwe amadziwikanso kuti matope obowola) ndi ofunikira pakupaka mafuta, kuziziritsa, ndi kuchotsa zinyalala. Madziwa amayenera kukhala ndi mamasukidwe oyendetsedwa bwino kuti anyamule zodula zobowola pamwamba ndikusunga bata mubowolo. CMC imagwira ntchito ngati rheology modifier mumadzi obowola, kulola mainjiniya kuwongolera ndendende kukhuthala ndi kutuluka kwamatope. Posintha kuchuluka kwa CMC, obowola amatha kusinthira kukhuthala kwamadzimadzi kuti akwaniritse zofunikira zamitundu yosiyanasiyana yobowola, monga kutentha kosiyanasiyana ndi kukakamiza mapangidwe.

2. Kuwongolera kusefa:

Kuwongolera kutayika kwamadzimadzi kapena kusefera ndikofunikira pakubowola mafuta kuti tipewe kuwonongeka kwa mapangidwe ndi kusunga chitsime cha chitsime. CMC imagwira ntchito ngati njira yowongolera kusefera popanga keke yopyapyala, yosasunthika pakhoma la borehole. Keke ya fyulutayi imasindikiza bwino mapangidwe ake ndi kuchepetsa kutaya kwa madzi obowola mu thanthwe lozungulira, motero kuchepetsa kuwonongeka kwa mapangidwe ndi kusunga kukhulupirika kwa nkhokwe. Kuphatikiza apo, CMC imathandizira kukulitsa kukhulupirika ndi kulimba kwa keke ya fyuluta, kuwonetsetsa kuti chitsime chikhale chokhazikika pakanthawi kobowola.

3. Kuyimitsa Kubowola Zodula:

Pobowola, kudula kwa miyala kumapangidwa pamene chobowola chimalowa m'mapangidwe apansi panthaka. Kuyimitsidwa koyenera kwa ma cuttingswa mumadzimadzi obowola ndikofunikira kuti asakhazikike ndikuwunjikana pansi pa dzenje, zomwe zingalepheretse kubowola ndikuwononga zida. CMC amachita ngati suspending wothandizira, kuthandiza kusunga pobowola cuttings omwazikana ndi inaimitsidwa mu madzimadzi. Izi zimatsimikizira kuchotsedwa kosalekeza kwa zodulidwa kuchokera pachitsime ndikusunga bwino pobowola bwino.

4. Kuchepetsa Kuwonongeka Kwamapangidwe:

Nthawi zina pobowola, makamaka m'malo ovuta kapena mosungira, kugwiritsa ntchito madzi ena obowola kumatha kuwononga mapangidwe chifukwa cha kulowerera kwamadzimadzi komanso kuyanjana ndi matrix a rock. Madzi obowola opangidwa ndi CMC amapereka zabwino pakuchepetsa kuwonongeka kwa mapangidwe, chifukwa chogwirizana ndi mapangidwe osiyanasiyana komanso kusagwirizana kochepa ndi madzi opangira. Zomwe sizikuwononga za CMC zimathandizira kuti posungira madzi asungidwe komanso porosity, kuwonetsetsa kuti ma hydrocarbon apangidwe bwino komanso magwiridwe antchito a posungira.

5. Zoganizira Zachilengedwe ndi Chitetezo:

Madzi obowola opangidwa ndi CMC nthawi zambiri amakondedwa chifukwa cha zabwino zake zachilengedwe komanso chitetezo. Poyerekeza ndi zina zowonjezera, CMC ndi yowola komanso yopanda poizoni, imachepetsa kuwonongeka kwa chilengedwe pakubowola ndikuchepetsa zoopsa kwa ogwira ntchito ndi nyama zakuthengo. Kuphatikiza apo, zamadzimadzi zochokera ku CMC zimawonetsa kawopsedwe pang'ono ndipo zimakhala ndi zoopsa zochepa paumoyo kwa ogwira ntchito kubowola, zomwe zimathandizira kuti pakhale malo otetezeka ogwirira ntchito pobowola mafuta.

Pomaliza:

Pomaliza, CMC imagwiritsidwa ntchito kwambiri pobowola mafuta chifukwa chotha kuthana ndi zovuta zosiyanasiyana zomwe zimakumana ndi pobowola. Kuchokera pakuwongolera kukhuthala kwamadzimadzi ndi kusefera mpaka kuyimitsa kudula ndikuchepetsa kuwonongeka kwa mapangidwe, CMC imagwira ntchito yofunikira pakuwongolera bwino pakubowola, kuonetsetsa kuti chitsime chikhazikika, ndikuchepetsa kuwonongeka kwa chilengedwe. Kusinthasintha kwake, kuchita bwino, komanso chitetezo kumapangitsa CMC kukhala chowonjezera chomwe chimakondedwa pakupanga madzi akubowola, kuthandizira kufufuza ndi kupanga mafuta moyenera.
