Polyanionic Cellulose (Pac) inguva yemvura-soluble cellulose inoshandiswa zvakanyanya mumaindasitiri yemafuta negesi, kunyanya mukufungidzira maficha emvura. Hydraulic Bracturing, inowanzozivikanwa sekukwezva, hunyanzvi hwekukurudzira hwakashandiswa kuwedzera kubviswa kwemafuta uye zvakasikwa gasi kubva pasi pevhu reservoirs. PACS vanotamba zvakasiyana siyana zvezviitiko zvekushora mune dhizaini uye kuurayiwa kweHydraulic Fracturing mashandiro, zvichikonzera kushanda, kugadzikana uye nekubudirira uye kwakazara kwekubudirira kwemaitiro.
1. Nhanganyaya kuPolyanionic Cellulose (PAC):
Polyanionic Cellulose inotorwa kubva kuCellulose, polymer yakasikwa inowanikwa mumadziro echitokisi. Iko kugadzirwa kwePAC kunosanganisira shanduko yemakemikari yemheremalose, zvichikonzera mumvura-solublable anionic polymer. Zvivakwa zvaro zvakasarudzika zvinoita kuti zviite kuti zviite zvakasiyana siyana zvekushandisa, kusanganisira sekiyi inokosha mukukanganiswa kwemvura fluid.
2. Basa rePac mumvura inokona:
Kuwedzera Pac kuti kupfuudza mvura inokwereta kunogona kushandura zvivakwa zvayo zvekunyepedzera, kudzora kurasikirwa kwemvura, uye kugadzirisa zvese zvakazara kuita. Zvivakwa zvayo zvezvivakwa zvezvivakwa zvinopa kubudirira kwe hydraulic bracturing munzira dzakawanda.
2.1 Rheological Shigezation:
Pac inoita senge rheology modifier, ichikanganisa visikopa uye kuyerera maitiro ekupwanya emvura. Kudzokorodza viscosity kunokosha kuti uwedzere kurongeka kuburitsa
2.2 Mvura Kurasikirwa Kwekutonga:
Imwe yezvinetso zve hydraulic bracturing iri kudzivirira yakawandisa mvura kubva pakurasika mukuumbwa. Pac inogona kuita zvinobudirira kudzora kurasikirwa kwemvura uye kuumba iyo yekudzivirira faira yeketi pane inovhiringidza nzvimbo. Izvi zvinobatsira kuchengetedza kutendeka kwakapetwa, kunodzivirira kudzikisira kwemabhebhi uye kunoparadza kuenderera mberi kwechibereko zvakanaka.
2.3 Kupisa Kugadzikana:
Pac isimbishi yakagadzikana, chinhu chakakosha muHydraulic Fracturing mashandiro, izvo zvinowanzoda kuratidzwa kune yakakura tembiricha. Kugona kwePac kuchengetedza mashandiro ayo pasi pemamiriro ezvinhu akasiyana ekupisa anobatsira kuvimbika uye kubudirira kwekufungidzira maitiro.
3. Zvichenjerera for formula:
Kubudirira Kushandiswa kwePAC mumvura inokatyamadza kunoda kunyatsofungisisa nezvemhando dzekuumbwa. Izvi zvinosanganisira kusarudzwa kwePAC giredhi, kusangana, uye kuwirirana nevamwe vanowedzera. Kubatanidzwa pakati pePac uye zvimwe zvikamu mukuputsika kwemvura, senge kuyambuka-manyoro uye mabhureki, vanofanirwa kuve vakagadzirirwa kuita zvakaringana.
4. Uye zvakatipoteredza uye kutevedzera kufunga:
Sekuziva kwekuzivisa nezvenhoroondo uye hydraulic fracturing mitemo inoramba ichisvika, kushandiswa kwePacc mukuputika kwemvura kunoenderana nekuedza kwemaindasitiri kukudziridza hunhu hwakawedzera. Pac iri mvura-inokatyamadza uye isingaiti, kuderedza mamiriro ekunze emamiriro ekunze uye kugadzirisa matambudziko kwakabatana nekuwedzera kwemakemikari muHydraulic kupwanyika.
5. Nyaya dzezvidzidzo uye zvikumbiro zvemunda:
Zvikamu zvakati wandei zvidzidzo uye zvikumbiro zvemunda zvinoratidza kushandiswa kwakabudirira kwePac muHydraulic kupwanyika. Iyi mienzaniso inoratidza kuvandudzwa kwekuita, zvinodhura-zvinobudirira uye zvakanakira zvakatipoteredza kwekubatanidza pac mumakara mavara.
6. Zvinonetsa uye zvinoshamisa zvenguva yemberi:
Nepo Pac yakaratidza kuve chinhu chakakosha mumvura inokatyamadza, matambudziko anoramba akadai sezvinhu zvakaenderana nezvimwe zvinhu zvekuumbwa uye kudiwa kwekuwedzera kutsvagisa mukukanganisa kwavo kwenguva refu. Zviitiko zvenguva yemberi zvinogona kutarisa pakutaura nematambudziko aya, pamwe nekuongorora manhamba matsva uye matekinoroji kuti uwedzere kushanda uye kuchengetedza kwehydraulic inokatyamadza mashandiro eHydraulic.
7. Mhedziso:
Polyanionic Cellulose (Pac) anoita basa rakakosha mukuumbwa kwekupwanya mvura yehupombwe kuti hydraulic inokanganisa mashandiro mumafuta negesi. Zvivakwa zvaro zvakasarudzika zvinopa kune rheology kudzora, kurasikirwa kwekurasikirwa kwekudzivirira uye tembiricha kugadzikana, pakupedzisira kunovandudza kubudirira kwechiitiko chekuparadza. Sezvo indasitiri ichiramba ichishanduka, kushandiswa kwePac kunoenderana nekufunga kwezvakatipoteredza uye zvinodiwa zvekutonga, zvichiita chinhu chakakosha mukuvandudzwa kwekusimudzira hydraulic fracturity maitiro ekufungidzira. Kuenderera mberi kwekutsvaga uye kusimudzira kuedza kunogona kutungamira kune kufambira mberi kuenderera mberi muPac-based bracturity mafomu ekuratidzira, kugadzirisa matambudziko uye kugadzirisa mamiriro ezvinhu pasi pemamiriro ezvinhu akasiyana uye anoshanda.
