Ma cellulose a Hydroxyethyl mu Fluid Fracturing mu Kubowola Mafuta

Hydroxyethyl cellulose (HEC) nthawi zina amagwiritsidwa ntchito pobowola mafuta, makamaka pobowola mafuta, omwe amadziwika kuti fracking. Madzi ophwanyidwa amalowetsedwa m'chitsime mothamanga kwambiri kuti apange ma fractures pamiyala, zomwe zimapangitsa kuti mafuta ndi gasi azitulutsa. Umu ndi momwe HEC ingagwiritsire ntchito pamadzi ophwanyidwa:

1. Kusintha kwa Viscosity: HEC imagwira ntchito ngati rheology modifier, yomwe imathandizira kuwongolera kukhuthala kwamadzi ophulika. Posintha kuchuluka kwa HEC, ogwiritsa ntchito amatha kusintha mawonekedwe a viscosity kuti akwaniritse zomwe akufuna, ndikuwonetsetsa kuyendetsa bwino kwamadzimadzi komanso kuphulika kwa fracture.
2. Fluid Loss Control: HEC imatha kuthandizira kuwongolera kutayika kwamadzimadzi pamapangidwe panthawi ya hydraulic fracturing. Zimapanga keke yopyapyala, yosasunthika pamakoma ophwanyika, kuchepetsa kutaya kwamadzimadzi ndikuletsa kuwonongeka kwa mapangidwe. Izi zimathandiza kusunga kukhulupirika kwa fracture ndikuwonetsetsa kuti nkhokwe ikugwira ntchito bwino.
3. Kuyimitsidwa kwa Proppant: Madzi a Fracturing nthawi zambiri amakhala ndi zowonjezera, monga mchenga kapena particles za ceramic, zomwe zimalowetsedwa m'mafupa kuti zitseguke. HEC imathandiza kuyimitsa ma propps awa mkati mwamadzimadzi, kuteteza kukhazikika kwawo ndikuwonetsetsa kugawidwa kwa yunifolomu mkati mwa fractures.
4. Fracture Cleanup: Pambuyo pa fracturing ndondomeko, HEC ikhoza kuthandizira kuyeretsa madzi otsekemera kuchokera ku chitsime ndi fracture network. Kukhuthala kwake komanso kuwongolera kutayika kwamadzimadzi kumathandiza kuonetsetsa kuti fracturing fluid imatha kubwezeretsedwanso bwino pachitsime, zomwe zimapangitsa kuti mafuta ndi gasi ayambe.
5. Kugwirizana ndi Zowonjezera: HEC imagwirizana ndi zowonjezera zosiyanasiyana zomwe zimagwiritsidwa ntchito popanga madzi ophwanyika, kuphatikizapo biocides, corrosion inhibitors, ndi friction reducers. ngakhale ake amalola chiphunzitso cha makonda fracturing madzi ogwirizana ndi mikhalidwe chitsime ndi zofunika kupanga.
6. Kukhazikika kwa Kutentha: HEC imawonetsa kukhazikika kwamafuta abwino, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mumadzi ophwanyidwa omwe amawonekera kumtunda wapamwamba kwambiri. Imasunga mawonekedwe ake a rheological komanso kuchita bwino ngati chowonjezera chamadzimadzi pansi pamikhalidwe yovuta kwambiri, kuwonetsetsa kuti ikugwira ntchito mosadukiza panthawi ya hydraulic fracturing.

Hydroxyethyl cellulose (HEC) imatha kutenga gawo lofunikira popanga madzi ophwanyira pobowola mafuta. Kusintha kwake kwa viscosity, kuwongolera kutaya kwamadzimadzi, kuyimitsidwa kwaposachedwa, kugwirizana ndi zowonjezera, kukhazikika kwa kutentha, ndi zinthu zina zimathandizira kuti magwiridwe antchito a hydraulic fracturing agwire bwino ntchito. Komabe, ndikofunikira kulingalira za mawonekedwe a nkhokweyo komanso momwe zinthu ziliri popanga ma fracturing fluid formulations okhala ndi HEC.
