Kushandiswa kweCMC muOilfieldIndasitiri

Carboxymethyl cellulose (CMC) inoshandiswa zvakanyanya muindasitiri yemafuta kune akasiyana maapplication nekuda kweyakasiyana zvivakwa uye kushanda kwayo. Inoshanda sechinhu chinogoneka chekuwedzera mumvura yekuchera, mvura yekupedzisa, uye simendi slurries, pakati pezvimwe zvinoshandiswa. Heano mamwe akajairika kushandiswa kweCMC muindasitiri yemafuta:

1. Drilling Fluids:

• Viscosifier: CMC inoshandiswa sechinhu chinovhenekera mumvura-yakavakirwa mvura yekuchera kuwedzera viscosity uye kunatsiridza kutakura kwemvura. Inobatsira kuchengetedza wellbore kugadzikana, kumisa kucheka, uye kudzora kurasikirwa kwemvura panguva yekuchera.
• Fluid Kurasika Kudzora: CMC inoita seyekurasikirwa kwemvura yekudzora mumiriri nekugadzira keke rakatetepa, risingapindiki refirita pamadziro etsime, kudzivirira kurasikirwa kwemvura yakawandisa mukuumbwa.
• Shale Inhibition: CMC inobatsira kudzikamisa kuzvimba kweshale uye kupararira nekuputira nzvimbo dzeshale uye kudzivirira hydration yezvikamu zvevhu, kuderedza njodzi yekusagadzikana kwegomba uye zviitiko zvepombi dzakanamira.
• Clay Kudzikamisa: CMC inodzikamisa ivhu rinoshanda zvicherwa mumvura yekuchera, kudzivirira kuzvimba kwevhu uye kutama, uye kunatsiridza mashandiro ekuchera muvhu-rakapfuma maumbirwo.

2. Kupedzisa Zvinwiwa:

• Fluid Kurasika Kudzora: CMC inowedzerwa kune yekupedzisa zvinwiwa kudzora kurasikirwa kwemvura mukuumbwa panguva yekupedza mutsime uye workover mashandiro. Inobatsira kuchengetedza kuumbwa kwekuvimbika uye kudzivirira kukanganisa kuumbwa.
• Shale Kudzikamiswa: CMC inobatsira mukudzikamisa shale uye kudzivirira shale hydration uye kuzvimba panguva yekupedzisa maoparesheni, kuderedza kusagadzikana kwegomba uye kuvandudza goho rakanaka.
• Sefa Keke Kuumbwa: CMC inosimudzira kuumbwa kweyunifomu, isingapindike sefa keke pachiso chechimiro, ichidzikisa mutsauko kudzvanywa uye kusimuka kwemvura mukuumbwa.

3. Cementing Slurries:

• Fluid Loss Additive: CMC inoshanda sekuwedzera kwekurasikirwa kwemvura mukusimbisa slurries kuderedza kurasikirwa kwemvura mumaumbirwo anokwenenzverwa uye kunatsiridza simende yekuisa zvakanaka. Inobatsira kuve nechokwadi chekuzviparadzanisa kwenzvimbo uye simende kusungirirwa.
• Thickening Agent: CMC inoita seyakakora mumiriri mune simende slurries, ichipa viscosity control uye inosimudzira kupomba uye kumiswa kwemasimende masimende panguva yekuiswa.
• Rheology Modifier: CMC inogadzirisa rheology yesimende slurries, inovandudza kuyerera zvivakwa, sag kuramba, uye kugadzikana pasi pemamiriro ekudzika.

4. Kuwedzera Kudzoreredza Oiri (EOR):

• Mafashamo eMvura: CMC inoshandiswa mukuita mafashama emvura kusimudzira kutsvaira nekunatsiridza kudzoreredza kwemafuta kubva mumadhamu. Iyo inowedzera viscosity yemvura yejekiseni, inovandudza kudzora kwekufamba uye kugona kwekufambisa.
• Mafashama ePolymer: Mumafashama epolymer, CMC inoshandiswa semugadziri wekufamba kuvandudza kuenderana kwemapolima akajairwa uye kuwedzera kutsvaira kwekubvisa mvura.

5. Kutsemuka Zvinwiwa:

• Fluid Viscosifier: CMC inoshandiswa seviscosifying mumiriri mune hydraulic fracturing zvinwiwa kuwedzera fluid viscosity uye propant kutakura kugona. Inobatsira kugadzira uye kuchengetedza mafractures mukuumbwa uye inosimudzira kufambisa uye kuiswa.
• Fracture Conductivity Enhancement: CMC inobatsira mukuchengetedza proppant pack kutendeseka uye kutyoka conductivity nekudzikisa kudonha kwemvura mukugadzira uye kudzivirira propant kugadzirisa.

Muchidimbu,carboxymethyl cellulose(CMC) inoita basa rakakosha mukushandisa kwakasiyana-siyana mukati meindasitiri yemafuta, zvinosanganisira zvinwiwa zvekuchera, zvinwiwa zvekupedzisa, simendi slurries, kuwedzera mafuta kudzoreredza (EOR), uye zvinwiwa zvinoputika. Kuita kwayo kwakasiyana-siyana seyekurasikirwa kwemvura yekudzora mumiririri, viscosifier, shale inhibitor, uye rheology modifier inoita kuti ive chinhu chinodiwa chekuwedzera kuve nechokwadi chekushanda uye kubudirira kwemafuta mumunda.
