Hydroxyethyl cellulose muDrilling Fluid

Hydroxyethyl cellulose (HEC) inowanzoshandiswa mukuchera zvinwiwa zvemafuta uye gasi kuongorora nekugadzira.Inoshanda zvakasiyana siyana uye inopa akati wandei mabhenefiti mune iyi application.Heano maitiro HEC inoshandiswa mukuchera zvinwiwa:

1. Rheology Kudzora: HEC inoita seye rheology inoshandura mumvura yekuchera, ichibatsira kudzora viscosity yemvura uye kuyerera zvinhu.Inosimudzira kugona kwemvura yekumisa uye kutakura zvibooreso zvakachekwa kumusoro, kudzivirira kugadzika kwavo uye kuchengetedza gomba kugadzikana.
2. Fluid Kurasika Kudzora: HEC inobatsira kudzikisa kurasikirwa kwemvura kubva mukuchera zvinwiwa kuita zvinopinda mafomati, izvo zvinogona kukonzera kusagadzikana uye kukuvara kwekugadzira.Iyo inoumba keke rakatetepa, risingapindiki resefa pachiso chechimiro, ichidzikisa kurasikirwa kwemvura yekuchera uye kuderedza kupinda kwemvura.
3. Kuchenesa Gomba: HEC inobatsira mukucheneswa kwegomba nekuvandudza kugona kwekutakura kwemvura yekuchera uye kufambisa kubviswa kwekuchekwa kwechibhorani kubva mutsime.Inosimudzira kumira kweiyo mvura, kudzivirira kuoma kubva pakugadzirisa uye kuunganidza pasi pegomba.
4. Temperature Stability: HEC inoratidza kugadzikana kwakanaka kwekushisa uye inogona kumira zvakasiyana-siyana zvekushisa zvinosangana panguva yekuchera mabasa.Iyo inochengetedza rheological properties uye inobudirira sechinhu chinowedzera chemvura pasi pemamiriro ekupisa kwepamusoro, kuve nechokwadi chekushanda kwakagadzikana munzvimbo dzakaoma dzekuchera.
5. Kushivirira Munyu: HEC inoenderana neyakakura salinity yekuchera zvinwiwa uye inoratidza yakanaka kushivirira munyu.Iyo inoramba ichishanda se rheology modifier uye fluid kurasikirwa inodzora mumiriri mukuchera zvinwiwa zvine huwandu hwakanyanya hwemunyu kana mabrines, anowanzo sangana mukuchera kumahombekombe kwemahombekombe.
6. Iine Hushamwari Nezvakatipoteredza: HEC inotorwa kubva kune inogona kuvandudzwa cellulose masosi uye ine hushamwari kwezvakatipoteredza.Kushandiswa kwayo mukuchera zvinwiwa kunobatsira kuderedza kukanganiswa kwezvakatipoteredza kwemabasa ekuchera nekudzikisa kurasikirwa kwemvura, kudzivirira kukuvadzwa kwekuumbwa, nekuvandudza kugadzikana kwegomba.
7. Kuenderana neAdditives: HEC inowirirana nehuwandu hwakawanda hwekuchera mvura inowedzera, kusanganisira shale inhibitors, lubricant, uye weighting agents.Inogona kuiswa nyore nyore mukuchera magadzirirwo emvura kuti uwane inodiwa maitiro ekuita uye kusangana nematambudziko ekuchera.

Hydroxyethyl cellulose (HEC) inowedzerwa zvakasiyana-siyana mumvura yekuchera, iyo inobatsira kudzora viscosity, kudzora kurasikirwa kwemvura, kuchenesa gomba, kugadzikana kwekushisa, kushivirira kwemunyu, kuchengetedza kwezvakatipoteredza, uye kuenderana nezvimwe zvinowedzera.Kubudirira kwayo mukunatsiridza kuita kwemvura yekuchera kunoita kuti ive chinhu chakakosha mukutsvagisa oiri uye gasi uye mashandiro ekugadzira.
