Kūʻai nui ʻo Hydroxy Propyl Methyl Cellulose Ether - Carboxymethyl cellulose CMC-Oil drilling - Yeyuan

Ke kumu hoʻohālike CMC papa ʻaila: CMC – HV; CMC- LV ; CMC－LVT/LV; CMC－HVT

Loaʻa iā ia ka hiki ke hoʻomalu i ka wai, ʻoi aku ka maikaʻi o ka hoʻemi ʻana i ka wai. Me ka haʻahaʻa haʻahaʻa, hiki iā ia ke hoʻomalu i ka nalowale o ka wai ma kahi kiʻekiʻe me ka ʻole o ka pili ʻana i nā waiwai ʻē aʻe o ka lepo;

Loaʻa iā ia ka pale wela maikaʻi a me ke kūpaʻa paʻakai maikaʻi loa. Hiki iā ia ke loaʻa ka hiki ke hoʻemi maikaʻi i ka wai a me kekahi rheology ma lalo o kahi paʻakai paʻakai. ʻAʻole loli ka viscosity ma hope o ka hoʻoheheʻe ʻana i ka wai paʻakai. He kūpono loa ia no ka ʻeli ʻana i waho a me nā luawai hohonu;

Hiki iā ia ke hoʻomalu maikaʻi i ka rheology o ka lepo a he thixotropy maikaʻi. He kūpono ia no kēlā me kēia lepo i hoʻokumu ʻia i ka wai i loko o ka wai hou, ka wai kai a me ka brine saturated;

CMC-noi ma ka aila

1. ʻO ke kuleana o CMC ma ka māla aila penei:
- Hiki i ka CMC ke ho'ēmi i ka lilo o ka wai o ka pā punawai a hoʻemi i ka permeability o ka lepo;
- Ma hope o ka hoʻohui ʻana i ka CMC i loko o ka ʻōpala, hiki i ka rig wili ke loaʻa i ka ikaika ʻoki mua haʻahaʻa, i maʻalahi ka lepo e hoʻokuʻu i ke kinoea i ʻōwili ʻia i loko, a hiki ke hoʻolei koke ʻia ka ʻōpala i loko o ka lua lepo;
- E like me nā mea hoʻopuehu ʻē aʻe, loaʻa kahi manawa o ka ʻeli ʻana i ka lepo, hiki ke hoʻopaʻa ʻia a hoʻonui ʻia ma hope o CMC.

2. Loaʻa iā CMC ka hana maikaʻi loa ma ka noi ʻaila:
- Ke kūlana hoʻololi kiʻekiʻe, ka hoʻololi hoʻololi maikaʻi, ka viscosity kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, hiki ke hoʻomaikaʻi maikaʻi i ka lawelawe pono o ka lepo;
- Ke kūpaʻa maikaʻi o ka wai, ka paʻakai paʻakai a me ke kūpaʻa alkali, kūpono no ka wai hou, ka wai kai a me ka ʻōpala wai i hoʻopaʻa ʻia i ka brine;
- He ʻano maikaʻi a kūpaʻa ka keke lepo i hana ʻia, hiki ke hoʻopaʻa pono i ka lepo palupalu
- He kūpono ia no nā ʻōnaehana lepo me ka mana paʻa paʻa paʻakikī a me ka laulā ākea.
