Basa remaindasitiri epolyacrylamide mukubvisa mafuta
Hunhu hwepolyacrylamide yeindasitiri pakuita kuti mafuta akonje, atsvedzerere uye agadziriswe zvakanaka, zvinoita kuti ive nebasa guru mukugadzira mafuta. Inoshandiswa zvakanyanya mukuchera, kuvhara mvura, kuita kuti mvura ive neacid, kupwanyika, kugeza matsime, kupedzisa matsime, kuderedza kudhonzwa, kuderedza kukura kwemafuta uye kusuduruka kwemafuta.
Kazhinji, kushandiswa kwepolyacrylamide kuri kuvandudza mwero wekudzoserwa kwemafuta. Kunyanya, minda mizhinji yemafuta yapinda mukugadzirwa kwechipiri nekwechitatu, kudzika kwedura kunowanzo pfuura 1000m, uye kumwe kudzika kwedura kunosvika 7000m. Kusiyana kwekugadzirwa kweminda yemafuta uye yekunze kwegungwa kwakaita kuti pave nemamiriro ezvinhu akaomarara ekuita kuti mafuta adzoserwe.
Pakati pazvo, kugadzirwa kwemafuta kwakadzika uye kugadzirwa kwemafuta ekunze kwenyika zvakapawo zvinodiwa zvitsva zvePAM, zvichiimanikidza kuti isatsvedze, kupisa kwakanyanya (kupfuura 100 ° C kusvika 200 ° C), calcium ion, magnesium ion, kuramba kusvibiswa nemvura yegungwa, kubvira kuma1980. Kufambira mberi kukuru kwakaitwa mukutsvagisa kwekutanga, kugadzirira, kutsvaga mashandisirwo uye kugadzirwa kwemhando dzakasiyana dzePAM dzakakodzera kudzoreredzwa kwemafuta kunze kwenyika.
Industrial polyacrylamide inoshandiswa se adjuster yekuchera mvura uye chinowedzera chemvura inopwanyika:
Polyacrylamide (HPAM) yakasanganiswa nemvura (hydrolyzed) zvishoma, iyo inobva mukusanganiswa kwepolyacrylamide, inowanzoshandiswa semuchina wekugadzirisa mvura yekuboorera. Basa rayo nderekugadzirisa rheology yemvura yekuboorera, kutakura zvidimbu, kuisa mafuta muchikamu chekuboorera, kuderedza kurasikirwa kwemvura, nezvimwewo. Mvura yekuboorera inogadziriswa nepolyacrylamide ine simba rakaderera, izvo zvinogona kuderedza kumanikidzwa nekuvharika kwenzvimbo yemafuta negasi, zviri nyore kuwana nzvimbo yemafuta negasi, uye inobatsira pakuboorera, kumhanya kwekuboorera kwakakwira ne19% kupfuura mvura yekuboorera yakajairika, uye inenge 45% yakakwira kupfuura mwero wekuboorera wemakanika.
Pamusoro pezvo, inogona kuderedza zvakanyanya tsaona dzekuboorwa kwemvura dzakamira, kuderedza kupera kwemidziyo, uye kudzivirira kurasikirwa nekuputsika. Tekinoroji yekupwanya matombo inzira yakakosha yekukurudzira kugadzira mibhedha yakasimba munzvimbo dzine mafuta. Polyacrylamide crosslinked fracturing fluid inoshandiswa zvakanyanya nekuda kwekusviba kwayo kwakanyanya, kukweshana kwakaderera, kugona kwayo kusundirwa jecha kwakanaka, kusefa kushoma, kugadzikana kwakanaka kwekusviba, masara mashoma, kuwanikwa kwakafara, kugadzirira kuri nyore uye mutengo wakaderera.
Mukurapa kwekupwanyika uye kuita kuti iite acid, polyacrylamide inogadzirwa mumvura ine huwandu hwe0.01% kusvika 4% uye inopombwa muchimiro chepasi pevhu kuti ityore chimiro. Mushonga wepolyacrylamide weindasitiri une basa rekukora nekutakura jecha uye kuderedza kurasikirwa kwemvura yekupwanyika. Pamusoro pezvo, polyacrylamide ine simba rekuderedza kuramba, kuitira kuti kurasikirwa kwekumanikidzwa kunogona kuderedzwa.
