Nei CMC ichigona kushandiswa mukuchera oiri?

Carboxymethyl cellulose (CMC) inowana kushandiswa kwakakura mukuchera oiri nekuda kweiyo yakasarudzika zvimiro zvinogadzirisa akati wandei matambudziko anowanikwa mukuchera. Ichi ndicho chikonzero CMC ichishandiswa mukuchera oiri:

1. Fluid Viscosity Control:

Mumabasa ekuchera oiri, zvinwiwa zvekuchera (zvinozivikanwawo semadhaka ekuchera) zvakakosha pakuzora, kutonhora, uye kubvisa tsvina. Mvura idzi dzinoda kuve necontrolled viscosity kuti inyatso kutakura zvicherwa zvekuchera kusvika pamusoro uye kuchengetedza kugadzikana mugomba. CMC inoshanda seye rheology modifier mumvura yekuchera, ichibvumira mainjiniya kunyatso kudzora viscosity uye kuyerera kwedhaka. Nekugadzirisa kusungirirwa kweCMC, vashandi vekuchera vanogona kugadzirisa viscosity yemvura kuti isangane nezvinodiwa zvemhando dzakasiyana dzekuchera, senge tembiricha dzakasiyana uye kudzvanywa kwekugadzira.

2. Kudzora Kudzora:

Kudzora kurasikirwa kwemvura kana kusefa kwakakosha mukuchera oiri kudzivirira kukuvadzwa kwekuumbwa uye kuchengetedza kugadzikana kwetsime. CMC inoshanda sefiltration control agent nekugadzira keke rakatetepa, risingapindiki resefa pamadziro echibhorani. Iri keke resefa rinonyatsosimbisa kuumbwa uye kuderedza kurasikirwa kwemvura yekuchera mudombo rakatenderedza, nokudaro kuderedza kukuvadzwa kwekuumbwa uye kuchengetedza reservoir kutendeseka. Uyezve, CMC inobatsira kukwidziridza kutendeseka uye kusimba kwekeke resefa, kuve nechokwadi chekugara kwenguva refu kugadzikana panguva yekuchera.

3. Kumiswa kweDrilling Cuttings:

Panguva yekuchera, kucheka kwematombo kunogadzirwa sezvo dhiri rinopinda mukati meiyo subsurface maumbirwo. Kunyatsomiswa kwezvicherwa izvi mumvura yekuchera kwakakosha kudzivirira kugadzika uye kuungana pazasi pechibhorani, izvo zvinogona kukanganisa kufambira mberi kwekuchera uye kukonzeresa kukuvara kwemidziyo. CMC inoshanda senge inomisa mumiriri, ichibatsira kuchengetedza kuchera makucheka akaparadzirwa uye akamiswa mumvura. Izvi zvinogonesa kuenderera kubviswa kwekucheka kubva mugomba uye kuchengetedza kudhirowa kwakanyanya.

4. Formation Damage Mitigation:

Mune zvimwe zviitiko zvekuchera, kunyanya munzvimbo dzakasimba kana madhirigi, kushandiswa kweimwe mvura yekuchera kunogona kutungamira mukukuvadzwa kwekuumbwa nekuda kwekupinda kwemvura uye kusangana nedombo matrix. CMC-based drilling fluids inopa mabhenefiti mukuderedza kukuvadzwa kwekuumbwa, nekuda kwekuenderana kwavo neyakasiyana siyana maumbirwo uye kushoma kupindirana nemvura yekugadzira. Izvo zvisiri-kukuvadza zvimiro zveCMC zvinobatsira kuchengetedza reservoir permeability uye porosity, kuve nechokwadi chakakwana chekugadzirwa kwehydrocarbon mareti uye kuita reservoir.

5. Mafungiro Ezvakatipoteredza uye Chengetedzo:

CMC-based drilling fluids inowanzofarirwa kune yavo yezvakatipoteredza uye kuchengetedza mabhenefiti. Zvichienzaniswa nezvimwe zvinowedzerwa, CMC inoodza uye haina chepfu, ichideredza kukanganiswa kwezvakatipoteredza kwekuchera uye kuderedza njodzi kuvashandi nemhuka dzesango. Pamusoro pezvo, CMC-yakavakirwa zvinwiwa zvinoratidzira yakaderera muchetura uye inoisa shoma njodzi dzehutano kune vashandi vanochera, zvichibatsira kune yakachengeteka nharaunda yekushanda mumarigi ekuchera oiri.

Mhedziso:

Mukupedzisa, CMC inoshandiswa zvakanyanya mumabasa ekuchera oiri nekuda kwekugona kwayo kugadzirisa matambudziko akasiyana akasangana mukuchera. Kubva pakudzora viscosity yemvura uye kusefa kusvika pakumisa kuchekwa kwekuchera uye kuderedza kukuvadzwa kwekuumbwa, CMC inoita basa rakakosha mukugadzirisa kushanda kwekuchera, kuve nechokwadi chekugadzikana kwetsime, uye kuderedza kukanganiswa kwezvakatipoteredza. Kuita kwayo kwakasiyana-siyana, kushanda nesimba, uye kuchengeteka kunoita kuti CMC ive yekuwedzera inosarudzika mukugadzirwa kwemvura yekuchera, inotsigira inoshanda uye yakagadzikana yekuongorora oiri uye maitiro ekugadzira.
