Hydroxyethylcellulose (HEC) inoita basa rakakosha muindasitiri yekuchera oiri, kunyanya mumvura yekuchera kana madhaka. Mvura yekuchera yakakosha mukuchera matsime emafuta, ichipa mabasa mazhinji akadai sekutonhodza uye kudzosa zvimedu zvekuboorera, kutakura zvicherwa zvekuchera pamusoro, uye kuchengetedza kugadzikana kwemutsime. HEC chinhu chakakosha chekuwedzera mune izvi zvinwiwa zvekuchera, zvichibatsira kuvandudza kushanda kwavo kwese uye kuita.
Nhanganyaya yeHydroxyethyl Cellulose (HEC):
1. Chimiro chemakemikari uye zvivakwa:
Hydroxyethyl cellulose is nonionic, mvura-soluble polymer inowanikwa nekemikari shanduko ye cellulose.
Iro hydroxyethyl boka muchimiro chayo rinopa kunyungudika mumvura nemafuta, zvichiita kuti ive yakawanda.
Huremu hwayo hwemamorekuru uye dhigirii rekutsiva inokanganisa rheological zvimiro, izvo zvakakosha pakuita kwayo mukuchera zvinwiwa.
2.Rheological kugadziriswa:
HEC inoshandiswa se rheology modifier, inokanganisa mafambiro ekuyerera uye viscosity yemvura yekuchera.
Kudzora kwe rheological properties kwakakosha pakugadzirisa kushanda kwemvura yekuchera pasi pemamiriro akasiyana-siyana ekudzika.
3. Sefa yekudzora:
HEC inoshanda sefiltration control agent, kudzivirira kurasikirwa kwemvura yakawandisa mukuumbwa.
Iyo polymer inoumba keke rakatetepa, risingapindiki resefa patsime, ichideredza kudhirowa kwemvura kunopinda mumatombo akatenderedza.
4. Kuchenesa nekurembera:
HEC inobatsira kumisa kucheka kwekucheka, kudzivirira kuti vasagadzikane pazasi pegomba.
Izvi zvinoita kuti mugodhi ucheneswe, uchengetedze mugodhi wakajeka uye kudzivirira zvivharo zvinogona kukanganisa kuchera.
5. Kuzora uye kutonhora:
Iyo yekuzora zvimiro zveHEC inobatsira kuderedza kupokana pakati petambo yekuchera uye tsime, nekudaro kuderedza kusakara uye kubvaruka pamichina yekuchera.
Inobatsirawo kubvisa kupisa, kubatsira mukutonhodza kwechibhorani panguva yekuchera.
6. Kugadzikana kwekuumbwa:
HEC inosimudzira kugadzikana kwetsime nekudzikisa njodzi yekukuvara kwekuumbwa.
Inobatsira kuchengetedza kutendeseka kwetsime nekudzivirira kuputsika kana kuparara kwematombo akakomberedza maitiro.
7. Mvura-yakavakirwa mvura yekuchera:
HEC inowanzoshandiswa mumvura-based drilling fluids kupa viscosity uye kugadzikana kumvura yekuchera.
Kuenderana kwayo nemvura kunoita kuti ive yakakodzera kugadzira zvinwiwa zvekuchera zvakatipoteredza.
8. Dzvinyirira mvura yekuchera:
Mune inhibitory drilling zvinwiwa, HEC inoita basa mukudzora shale hydration, kudzivirira kuwedzera, nekuvandudza kugadzikana kwetsime.
9. Tembiricha yepamusoro nharaunda:
HEC yakagadzikana nemafuta uye yakakodzera kushandiswa mukuchera kwepamusoro-tembiricha.
Zvimiro zvaro zvakakosha kuchengetedza kushanda kwemvura yekuchera pasi pemamiriro ekushisa kwepamusoro.
10. Kuwedzera kuenderana:
HEC inogona kushandiswa pamwe chete nezvimwe zvekuchera zvinwiwa zvekuwedzera senge mapolymers, ma surfactants uye uremu maajenti kuti uwane inodiwa yemvura zvinhu.
11. Kuveura hunhu:
Kuveura kunosangana panguva yekuchera kunogona kukonzera HEC kudzikisira, inokanganisa rheological properties nekufamba kwenguva.
Kugadzira kwakaringana kwekuwedzera uye kusarudzwa kunogona kuderedza matambudziko ane chekuita neshear.
12. Kukanganisa kwezvakatipoteredza:
Nepo HEC ichiwanzoonekwa seine hushamwari kwezvakatipoteredza, iyo yakazara nharaunda kukanganisa kwemvura yekuchera, kusanganisira HEC, inyaya yekuenderera mberi kunetseka nekutsvaga.
13. Mari inotariswa:
Iko mari-inoshanda yekushandisa HEC mukuchera zvinwiwa ndeyekufunga, nevashandisi vanoyera mabhenefiti ekuwedzera maringe nemutengo.
mukupedzisa:
Muchidimbu, hydroxyethyl cellulose yakawedzera kukosha muindasitiri yekuchera mafuta, ichibatsira mukubudirira kwese uye kugona kwemabasa ekuchera. Mabasa ayo akawanda, anosanganisira rheology modification, filtration control, gomba kuchenesa uye kudzosa, inoita kuti ive chinhu chakakosha chemvura yekuchera. Sezvo mabasa ekuchera ari kuramba achishanduka uye indasitiri yakatarisana nematambudziko matsva uye kufunga nezvezvakatipoteredza, HEC inoramba ichiita basa rakakosha mukuona kuita kwakaringana uye kusimba kwekuchera mafuta. Kuenderera mberi nekutsvagisa uye kusimukira mupolymer chemistry uye yekuchera mvura tekinoroji inogona kubatsira mukuwedzera kufambira mberi uye kuvandudzwa mukushandiswa kwehydroxyethyl cellulose muindasitiri yeoiri negasi.
