Polyanionic Cellulose Oildrilling

Polyanionic cellulose (PAC) chinhu chakakosha chekuwedzera mumvura yekuchera oiri, ichishanda mabasa akasiyana siyana kukwenenzvera mashandiro ekuchera. Heino nzira iyo PAC inobatsira kune mafuta ekuchera zvinwiwa:

1. Viscosity Control: PAC inobatsira kudzora viscosity yemvura yekuchera, kuve nechokwadi kuti ine ukobvu hunodiwa kuti utakure zvakachekwa zvakachekwa kumusoro. Izvi zvakakosha pakuchengetedza kugadzikana kwetsime uye kudzivirira nyaya dzakaita sekudonha kwegomba.
2. Fluid Loss Prevention: PAC inoumba keke rakatetepa, risingapindike sefa pamadziro echibhorani, ichidzikisa kurasikirwa kwemvura muchimiro chakatenderedza. Nekudzikisa kurasikirwa kwemvura, PAC inobatsira kuchengetedza hydrostatic pressure, inodzivirira kukuvadzwa kwekuumbwa, uye inovandudza kugadzirwa zvakanaka.
3. Rheology Kugadziriswa: PAC inokanganisa maitiro ekuyerera uye rheological zvimiro zvemvura yekuchera, inosimudzira kumiswa kwezvakaoma uye kuderedza kugadzirisa. Izvi zvinogonesa kushanda kwakafanana kwemvura yekuchera pasi pemamiriro akasiyana ekudzika.
4. Kudzora uye Kuderedza Kudonhedza: PAC inopa lubrication pakati pechibhorani tambo uye tsime remadziro, kuderedza kukweshera uye kuderedza kudhonza. Izvi zvinobatsira kukwenenzvera kuchera, kuderedza kusakara pamidziyo yekuchera, uye kuwedzera hupenyu hwemidziyo.
5. Kunatsiridza Gomba Kuchenesa: Nekuwedzera viscosity uye kutakura kugona kwemvura yekuchera, PAC inofambisa kubviswa kweakachekwa akachekwa nemarara kubva mugomba, kunatsiridza kuchenesa gomba uye kuderedza njodzi yepombi yakanamira.
6. Tembiricha uye Salinity Kugadzikana: PAC inoratidza kushivirira kwakanyanya uye munyu, kuchengetedza viscosity yayo uye maitiro ekuita pamusoro pehupamhi hwetembiricha uye salinity inowanikwa mukuchera.
7. Iine Ushamwari Nezvakatipoteredza: PAC inotorwa kubva kune zvinogoneka kucherwa-zvimisikidzwa uye inoodza, zvichiita kuti ive nehushamwari kwezvakatipoteredza uye yakakodzera kushandiswa munzvimbo dzinocheresa nharaunda.

Muchidimbu, polyanionic cellulose chinhu chakakosha chemafuta ekuchera mvura, inopa viscosification, kudzora kurasikirwa kwemvura, rheology gadziriso, uye zvimwe zvakakosha zvivakwa kuti ive nechokwadi chekushanda uye budiriro yekuchera muindasitiri yemafuta negasi. Kuvimbika kwayo, kuita, uye kugarisana kwezvakatipoteredza kunoita kuti ive sarudzo inosarudzika yekukwenenzvera kuita kwemvura yekuchera uye kugadzikana kwetsime.
