2021 kumu kūʻai kūʻai nui Kina Mea hana Hydroxypropyl Methyl Cellulose - Carboxymethyl cellulose CMC-Water base fracturing wai - Yeyuan

He kiʻekiʻe ka lawe ʻana i ke one a me ke one consolidation hiki iā CMC ke lawe mai i ka proppant i nā haʻihaʻi hohonu hohonu, a hiki ke hōʻemi i ka wikiwiki o ke kākoʻo ʻana a ʻoi aku ka maikaʻi o ka ʻaila a me ke kinoea. No laila, ʻo nā pūnāwai aila a me ke kinoea ma hope o ka haʻi ʻana me CMC he hopena hoʻoulu nui, ʻoi aku ka kiʻekiʻe ma mua o nā mea i kūkulu ʻia me ka wai haʻihaʻi maʻamau.

CMC-noi o ka wai-ma muli o ka haʻihaʻi wai

1. He ikaika loa ka mānoanoa, ʻoi aku ka ikaika ma mua o ko ka guar gum, a ʻoi aku ka maikaʻi o ka hoʻopuehu ʻana;
2. ʻO ka ikaika o ke one i hoʻokuʻu ʻia, haʻahaʻa kānana nalowale, emi ke koena a me ka maikaʻi thermal kūpaʻa, a ʻaʻole maʻalahi ke hoʻohaʻahaʻa ʻia e ka bacteria;
3. ʻO ke kūpaʻa shear maikaʻi, kūpono maikaʻi me nā paʻakai hoʻokumu, kūpaʻa paʻakai maikaʻi a me ke kumu kūʻai haʻahaʻa;
4. He haʻahaʻa ke koena maʻiʻo a he liʻiliʻi ka haumia i ka hoʻokumu ʻana;
5. Loaʻa iā ia ka hana fracturing maikaʻi a me ka paʻa ʻana o ka wai, hiki ke hoʻoheheʻe ʻia me nā kemika like ʻole, a ʻoi aku ka synergy;
6. Ma hope o ka haʻihaʻi ʻana, e noho mau ʻo CMC i ka haʻihaʻi a hui pū me ka proppant e hana i kahi hoʻolālā pūnaewele spatial e hoʻonui ai i ka cohesion o proppant, i mea e hoʻopaʻa ai i ka proppant ma ke kūlana kumu, a hiki i ka wai ke hele manuahi, i mea e e hoʻokō i ke kumu o ka pale ʻana i ka proppant backflow;
