Swell hais

Oplequle (feem ntau hu ua cov neeg sawv cev oxility los yog cov khoom noj khoom haus) tau siv rau hauv cov pob zeb hydraulic ib ntus thiab txhim kho kev txhawb nqa ib ntus Tsis zoo li cov khoom siv tau khoom muag o, cov lus no tau muab cov roj ntsha thiab cov roj ntsha uas twb muaj lawm thiab cov kua dej uas tsis txhim kho cov aav.

Yuav ua li cas oatable parsle cais pob zeb zomure:

• Kev txhaj tshuaj nrog cov kua frec - cov nplais me me tau muab sib xyaw rau hauv cov kua dej khov thiab ua kua rau hauv lub qhov dej.
• Kev tsiv teb tsaws kom qhib qhov tawg - cov lus ntws ntws mus rau hauv qhov tseem ceeb (high-permeability) tawg uas feem ntau noj cov kua.
• O & blockage - thaum muaj kev sib cuag nrog dej zoo (roj, lossis roj), cov lus nthuav dav thiab sib tsoo tawm cov pob txha uas twb muaj lawm.
• Lub siab sib txawv - nrog cov pob txha tseem ceeb thaiv, ua kom lub siab ua haujlwm, yuam cov kua dej rau hauv ib thaj chaw tshiab, hauv qab.

Kev ua rau muaj kev tawm tsam lossis khiav tawm - tom qab kev kho, cov lus hais tias:

• Degrade (yog tias tsis muaj tseeb)
• Tau tsim rov qab nrog cov kua dej ntws
• Hom ntawm opable partle:
• Roj-Oatable Particle - nthuav hauv hydrocarbon-nplua nuj ib puag ncig.
• Cov kua dej-dej uas muaj tseeb - hnov ​​mob nrog dej lossis brine.
• Thermary ua kom cov khoom siv - swell ntawm cov kub tshwj xeeb.
• Dissalvable hais - tawg nyob rau lub sijhawm kom tsis txhob muaj kev puas tsuaj.

Qhov Zoo:

• Txhim kho cov pob txha sib xyaw ua ke sib xyaw los ntawm kev ua kua rau mus rau hauv cov aav.
• Tsis muaj kev cuam tshuam txhua yam (tsis zoo li cov khoom sib cais zoo li pob zeb sib khi).
• Ua haujlwm nyob rau hauv qhib-qhov thiab cased-lub qhov zoo.
• Txo "FRAC ntaus" (tsis xav tau kev sib txuas lus ntawm qhov dej).

Cov Ntawv Thov:

• Kev tsim kho cov laus los txhawb cov thaj chaw tshiab.
• Divealing pob txha lov hauv ntau pawg.
• Tiv thaiv kev overgrowth ntawm tseem ceeb me me hauv kev tsis muaj cov dej num tsis txaus ntseeg.
