Makampani Opanga a Methyl Cellulose Water Thickener - Polyanionic cellulose (PAC) - Yeyuan

Polyanionic cellulose (PAC) ndi chochokera m'madzi chosungunuka cha cellulose ether chokonzedwa ndi kusintha kwa mankhwala a cellulose achilengedwe. Ndilofunika kusungunuka m'madzi cellulose ether. Nthawi zambiri amagwiritsidwa ntchito ngati mchere wa sodium ndipo amagwiritsidwa ntchito kwambiri pobowola mafuta, makamaka zitsime zamadzi amchere komanso pobowola mafuta akunyanja.

PAC-Kugwiritsa Ntchito Mu Petroleum

1. Ntchito za PAC ndi CMC m'munda wamafuta ndi izi:
- Matope okhala ndi PAC ndi CMC amatha kupanga khoma lachitsime kukhala lopyapyala komanso lolimba losefera keke ndi kutsika pang'ono ndikuchepetsa kutayika kwa madzi;
- Pambuyo powonjezera PAC ndi CMC m'matope, chobowoleracho chikhoza kupeza mphamvu yochepetsera yochepetsera, kupanga matope mosavuta kutulutsa mpweya wokulungidwa mmenemo, ndikutaya mwamsanga zinyalala mu dzenje lamatope;
- Monga mabala ena oyimitsidwa, matope obowola amakhala ndi nthawi yokhazikika, yomwe imatha kukhazikika ndikuwonjezedwa powonjezera PAC ndi CMC.
2. PAC ndi CMC ali ndi ntchito zotsatirazi zabwino kwambiri mu oilfield ntchito:
- Kusintha kwakukulu m'malo, kufanana kwabwino m'malo, kukhuthala kwakukulu ndi mlingo wochepa, kuwongolera bwino ntchito zamamatope;
- Kukana kwabwino kwa chinyezi, kukana kwa mchere ndi kukana kwa alkali, koyenera madzi abwino, madzi a m'nyanja ndi matope odzaza madzi a brine;
- Keke yamatope yomwe imapangidwa ndi yabwino komanso yokhazikika, yomwe imatha kukhazikika bwino nthaka yofewa ndikuletsa kugwa kwa khoma la shaft;
- Ndi yoyenera pamakina amatope omwe ali ndi zovuta zowongolera zolimba komanso kusiyanasiyana kosiyanasiyana.
3. Kagwiritsidwe ntchito ka PAC ndi CMC pakubowola mafuta:
- Imakhala ndi mphamvu yoletsa kutayika kwa madzi, makamaka yochepetsera kutaya kwamadzimadzi. Ndi mlingo wochepa, ukhoza kulamulira kutaya kwa madzi pamtunda wapamwamba popanda kukhudza zinthu zina zamatope;
- Imakhala ndi kutentha kwabwino komanso kukana mchere wabwino kwambiri. Ikhoza kukhalabe ndi mphamvu yabwino yochepetsera kutaya kwa madzi ndi rheology ina pansi pa mchere wina. The mamasukidwe akayendedwe pafupifupi zosasinthika pambuyo Kutha mu madzi amchere. Ndikoyenera makamaka pobowola m'mphepete mwa nyanja ndi zitsime zakuya;
- Ikhoza kulamulira bwino rheology yamatope ndipo ili ndi thixotropy wabwino. Ndiwoyenera matope aliwonse opangidwa ndi madzi m'madzi abwino, m'madzi a m'nyanja ndi brine yodzaza;
- Kuphatikiza apo, PAC imagwiritsidwa ntchito ngati simenti madzimadzi kuteteza madzimadzi kulowa pores ndi fractures;
- The fyuluta atolankhani madzimadzi okonzedwa ndi PAC ali kukana zabwino 2% KCl njira (iyenera kuwonjezeredwa pokonzekera fyuluta atolankhani madzimadzi), solubility wabwino, ntchito yabwino, akhoza kukonzekera pa malo, mofulumira gel osakaniza kupanga liwiro ndi wamphamvu mchenga kunyamula mphamvu. Ikagwiritsidwa ntchito popanga mapangidwe otsika, zosefera zake zimakhala zabwino kwambiri.
