Zvinoenderana neiyo nzira yekuisa makemikari emumunda weoiri, mafirita ekushandisa mumunda weoiri anogona kuiswa muchikamu nekushandiswa kune vanochera surfactants, vanogadzira surfactants, vakagadziridzwa mafuta ekudzoreredza surfactants, oiri negasi kuunganidza / ekufambisa ekufambisa, uye ekuchenesa mvura.
Drilling Surfactants.
Pakati pevashandi vemafuta emumunda, madhiri anochera (kusanganisira kuchera mvura yekuwedzera uye simende yekuwedzera) anotora huwandu hukuru hwekushandisa - ingangoita 60% yehuwandu hwemafuta emumunda wekushandisa. Magadzirirwo ekugadzira, kunyange ari madiki muhuwandu, ane tekinoroji yepamusoro, anoumba chikamu chimwe muzvitatu chehuwandu. Aya mapoka maviri ane kukosha kwakakosha muoirifield surfactant application.
MuChina, tsvagiridzo inotarisisa nzvimbo mbiri huru: kuwedzera kushandiswa kwezvinhu zvechinyakare mbishi uye kugadzira novel synthetic polymers (kusanganisira monomers). Pasi rose, kuchera mvura yekuwedzera kutsvagisa kunonyanya hunyanzvi, kusimbisa sulfonic acid boka-ine synthetic polymers sehwaro hwezvakasiyana zvigadzirwa - maitiro anogona kuumba budiriro yeramangwana. Kubudirira kwakaitwa mune viscosity reducers, fluid kurasikirwa control agents, uye lubricant. Zvikuru, mumakore achangopfuura, polymeric doro surfactants ine cloud point mhedzisiro yakagamuchirwa zvakanyanya munzvimbo dzese dzemafuta epamba, ichigadzira nhevedzano yepolymeric doro drilling fluid masisitimu. Pamusoro pezvo, methyl glucoside uye glycerin-based drilling fluids zvakaratidza vimbiso yemashandisirwo emumunda, zvichienderera mberi nekufambisa kuvandudzwa kwevanochera madhiri. Parizvino, yekuChina yekuchera mvura yekuwedzera inosanganisira zvikamu gumi nemasere zvine marudzi anopfuura chiuru, uye kushandiswa kwepagore kuri kusvika mazana matatu ezviuru zvematani.
Production Surfactants.
Zvichienzaniswa nekuchera ma surfactants, ma surfactants ekugadzira ari mashoma mumhando uye muhuwandu, kunyanya ayo anoshandiswa mu acidizing uye fracturing. Mukuita ma fracturing surfactants, kutsvagisa nezve gelling agents kunonyanya kutarisisa pane zvakagadziridzwa zvechidyarwa chingamu uye cellulose, padivi pezvakagadzirwa mapolymers sepolyacrylamide. Mumakore achangopfuura, kufambira mberi kwepasi rose mu acidizing fluid surfactants kwave kunonoka, nekusimbisa kweR&D kuchienda kucorrosion inhibitorskuitira acidizing. Aya ma inhibitors anowanzo kugadzirwa nekugadzirisa kana kusanganisa zvinhu zviripo, nechinangwa chakafanana chekuona kuti yakaderera kana isiri-chepfu uye kunyungudika kwemafuta / mvura kana kupararira kwemvura. Amine-based, quaternary ammonium, uye alkyne alcohol blended inhibitors zvakapararira, nepo aldehyde-based inhibitors yadzikira nekuda kwekunetsekana kwehupfu. Zvimwe zvitsva zvinosanganisira dodecylbenzene sulfonic acid complexes ine low-molecular-weight amines (eg, ethylamine, propylamine, C8-18 primary amines, oleic diethanolamide), uye acid-in-oil emulsifiers. KuChina, tsvakiridzo pamusoro pezvinwiwa zvinoputika uye acidizing zvinwiwa zvaramba, nekufambira mberi kushoma kupfuura corrosion inhibitors. Pakati pezvigadzirwa zviripo, amine-based compounds (primary, secondary, tertiary, kana quaternary amides nemisanganiswa yavo) inotonga, inoteverwa nemidazoline derivatives seimwe kirasi huru ye organic corrosion inhibitors.
Oiri uye Gasi Kuunganidza / Yekufambisa Surfactants.
Tsvagiridzo uye kuvandudzwa kwevagadziri vemafuta uye gasi kuunganidza / kutakura muChina kwakatanga muma1960s. Nhasi, kune 14 mapoka ane mazana ezvigadzirwa. Crude oil demulsifiers ndiyo inonyanya kudyiwa, ine kudiwa kwepagore kwematani anosvika zviuru makumi maviri. China yakagadzira akakwenenzverwa demulsifiers kune akasiyana minda yemafuta, mazhinji ayo anosangana nema1990s epasi rose zviyero. Nekudaro, dururira mapoinzi zvinoderedza, zvinonatsiridza kuyerera, zvinoderedza viscosity, uye kubvisa wakisi / kudzivirira vamiririri vanoramba vari vashoma, kunyanya zvichive zvigadzirwa zvakasanganiswa. Izvo zvinosiyana zvinodikanwa zveakasiyana crude oiri zvivakwa kune aya ma surfactants zvinounza matambudziko uye zvakakwirira zvinodiwa pakuvandudzwa kwechigadzirwa.
Oilfield Water Treatment Surfactants.
Makemikari ekurapa mvura iboka rakakosha mukusimudzira nhandare yemafuta, nekudyiwa kwepagore kunopfuura matani makumi matanhatu ezviuru - angangoita makumi mana muzana ari ma surfactants. Kunyangwe paine kudiwa kwakanyanya, kutsvagisa pamusoro pevanogadziriswa mvura muChina hakuna kukwana, uye huwandu hwechigadzirwa hunoramba husina kukwana. Zvigadzirwa zvakawanda zvinogadziriswa kubva mumaindasitiri emvura kurapwa, asi nekuda kwekuoma kwemvura yemumunda wemafuta, kushanda kwavo kunowanzo kuve kwakashata, dzimwe nguva kutadza kuunza zvinotarisirwa. Pasi rose, flocculant development ndiyo inonyanya kushanda munzvimbo yekuchenesa mvura yekutsvagisa surfactant, ichipa zvigadzirwa zvakawanda, kunyangwe zvishoma zvakagadzirirwa kuchenesa nzvimbo yemafuta.
