Polyanionic cellulose (PAC) ipolymer inonyungudika nemvura iyo inowanzoshandiswa muindasitiri yemafuta negasi sechinhu chekuchera mvura inowedzerwa.PAC inotorwa kubva ku cellulose, inova chikamu chikuru chezvimiro zvechirimwa maseru madziro.PAC inoshanda zvakanyanya mukuvandudza rheological zvimiro zvekuchera zvinwiwa, senge viscosity, fluid kurasikirwa control, uye kuturika zvivakwa.Ichi chinyorwa chichakurukura nezvezvivakwa, mashandisirwo, uye mabhenefiti ePAC mumafuta ekuchera peturu.

Zvivakwa zvePolyanionic Cellulose

PAC i polymer inonyungudika mumvura inotorwa kubva muselulosi.Iyo yakakwira molecular uremu komisheni ine carboxymethyl uye hydroxyl mapoka.Iyo dhigirii yekutsiva (DS) yePAC inoreva huwandu hweavhareji yemapoka ecarboxymethyl pane anhydroglucose unit ye ​​cellulose musana.Kukosha kweDS chinhu chakakosha cheparameter inobata zvinhu zvePAC, senge kunyungudika kwayo, viscosity, uye kugadzikana kwekupisa.

PAC ine chimiro chakasarudzika chinoibvumira kudyidzana nemamorekuru emvura uye mamwe mapolymer mumvura yekuchera.PAC mamorekuru anoumba matatu-dimensional network yehydrogen bond uye electrostatic kudyidzana nemamorekuru emvura uye mamwe mapolymeric additives, senge xanthan chingamu kana guar gum.Ichi chimiro chetiweki chinosimudzira viscosity uye shear-kutetepa maitiro ezvinwiwa zvekuchera, izvo zvakakosha zvivakwa pakuita basa rekuchera.

Zvishandiso zvePolyanionic Cellulose

PAC ipolymer inoshanda zvakasiyana-siyana inogona kushandiswa mumhando dzakasiyana dzekuchera mvura masisitimu, senge madhaka-akavakirwa mvura, madhaka ane mafuta, uye madhaka anogadzirwa.PAC inonyanya kushandiswa mumadhaka ane mvura nekuda kwekunakisa kunyungudika kwemvura uye kuenderana nezvimwe zvinowedzera.PAC inowedzerwa kumvura yekuchera pamitsetse inotangira pa0.1% kusvika 1.0% nehuremu, zvichienderana nemamiriro ekuchera uye zvinangwa.

PAC inoshandiswa mukuchera zvinwiwa kune akati wandei maapplication, kusanganisira:

1. Viscosification: PAC inowedzera kupenya kwemvura yekuchera, iyo inobatsira kumisa uye kutakura zvidimbu uye zvimwe zvinyoro kubva mugomba.PAC inobatsirawo kuchengetedza kutendeseka kwechitsime nekudzivirira kurasikirwa kwemvura muzvikamu zvinopinda.
2. Fluid kurasikirwa kwekudzora: PAC inoita senge yekudzora kurasikirwa kwemvura nekugadzira keke rakatetepa, risingapindike sefa pamadziro echibhorani.Iyi keke yekusefa inodzivirira kurasikirwa kwemvura yekuchera muchimiro, izvo zvinogona kukonzera kukanganisa kwekugadzira uye kuderedza kushanda kwekuchera.
3. Shale inhibition: PAC ine yakasarudzika dhizaini inoibvumira kushambadza pane yevhu zvicherwa uye shale maumbirwo.Iyi adsorption inoderedza kuzvimba uye kupararira kwemaitiro e shale, izvo zvinogona kukonzera kusagadzikana kwematsime uye mamwe matambudziko ekuchera.

Mabhenefiti ePolyanionic Cellulose

PAC inopa mabhenefiti akati wandei kumabasa ekuchera, kusanganisira:

1. Kukwenenzvera kuchera: PAC inokwidziridza rheological zvimiro zvekuchera zvinwiwa, senge viscosity uye fluid kurasikirwa kwekudzora.Izvi zvinovandudza kushanda zvakanaka kwekuchera nekudzikisa nguva nemari inodiwa pakuchera tsime.
2. Kudzivirirwa kwechimiro: PAC inobatsira kuchengetedza kutendeseka kwetsime nekudzivirira kurasikirwa kwemvura uye kuderedza kukuvadzwa kwekuumbwa.Izvi zvinodzivirira kuumbwa uye zvinoderedza njodzi yekusagadzikana kwetsime uye mamwe matambudziko ekuchera.
3. Kugarisana kwezvakatipoteredza: PAC ipolmer inonyungudika nemvura iyo inoodza uye inoenderana nenharaunda.Izvi zvinoita kuti ive yekuwedzera yakasarudzika yekuchera zvinwiwa munzvimbo dzakatipoteredza.

Mhedziso

Polyanionic cellulose inowedzera inoshanda zvakanyanya mupetroleum yekuchera zvinwiwa nekuda kweiyo yakasarudzika zvimiro uye kushandiswa kwakasiyana-siyana.PAC inokwidziridza rheological zvimiro zvezvinwiwa zvekuchera, inovandudza kuchera, uye inodzivirira kuumbwa kubva mukukuvadzwa.PAC zvakare inoenderana kwezvakatipoteredza uye inosarudzwa munzvimbo dzakaoma.Kushandiswa kwePAC mumvura yekuchera kunotarisirwa kuramba kuchikura mune ramangwana sezvo indasitiri yemafuta negasi iri kuramba ichitsvaga matekinoroji matsva ekuchera uye nzira dzekuwedzera kugadzirwa uye kuderedza mitengo.
