Khoom Taw Qhia
Pa fracturing nyiam sib txuas lus nrog cov cheeb tsam siab permeability, tab sis nws yog ib qho nyuaj rau cov cheeb tsam uas tsis muaj permeability uas yog ib qho tseem ceeb heev rau stimulation thiab reconstruction. Nyob rau hauv qhov kev pom ntawm qhov teeb meem no, diverting fracturing technology tau los ua. Los ntawm kev ntxiv diverting tus neeg sawv cev rau cov kua, ib ntus ntsaws cov kab permeability siab, yuam cov kua ntws mus rau qhov qis permeability txheej, yog li paub txog qhov sib txawv ntawm qhov tawg.
Lub tuam txhab tau tsim ib tug series ntawm nruab nrab, siab, uas tsis muaj kub siv ib ntus plugging pob khoom, yuav hloov mus rau txawv geological ib puag ncig. Nrog zoo dissolution thiab degradation kev ua tau zoo, raws li cov neeg siv khoom xav tau, tuaj yeem kho tus nqi degradation. Tam sim no, cov pa ntau thiab tsawg yog: 9mm, 12mm, 14mm, 15mm, 19mm, 22mm, 26mm txoj kab uas hla cov khoom tuaj yeem muab, kuj tuaj yeem kho raws li qhov xav tau tiag tiag ntawm cov neeg siv khoom.
Cim npe nrov: Tuam Tshoj Plug Pob Manufacturers, lwm tus neeg, Hoobkas
| Tus lej | Xim | Qhov ntom | Cov kabmob muaj zog | Dissolution tus nqi | Qhov kub ntawm kev siv |
| LB 40 | daj ntseg daj | 0 9-1.5g/cm3 | Ntau dua lossis sib npaug li 40MPa | Tsawg dua los yog sib npaug li 20h | 20-60 degree |
| LB 60 | Dawb / daj | 0 9-1.5g/cm3 | Ntau dua lossis sib npaug li 40MPa | 12-24h | 60-90 degree |
| HB 90 | dawb | 0 9-1.7g/cm3 | Ntau dua lossis sib npaug li 50MPa | 24-72h | 90-120 degree |
| HB 120 | dawb | 0 9-1.5g/cm3 | Ntau dua lossis sib npaug li 50MPa | 12-48h | 120-150 degree |
