Nws yog tsim tshwj xeeb los txo cov coefficient ntawm kev sib txhuam nyob rau hauv tag nrho cov dej-base drilling kua, uas txo torque thiab luag nyob rau hauv lub qhov dej.Nrog rau qhov tshwj xeeb wettability tus yam ntxwv uas txo qis lub peev xwm rau Bottom-Hole Assembly (BHA) balling, nws tsis muaj hydrocarbons thiab yog sib xws nrog tag nrho cov dej-base kua, suav nrog mono-/divalent brine kua.Nrog kev pab tsawg kawg nkaus rau cov khoom siv rheological ntawm cov av nkos, nws tsis ua npuas dej thiab tuaj yeem muab ntxiv rau hauv cov av nkos los ntawm kev sib xyaw hopper lossis ncaj qha mus rau qhov chaw ntawm qhov chaw uas muaj kev ntxhov siab zoo.
7-Qhov zoo
1. Ua tau zoo, tag nrho cov hom phiaj lubricant rau cov dej hauv av av
2. Txo cov coefficient ntawm kev sib txhuam uas txo torque thiab luag
3. Tsis nce rheology lossis gel zog
4. Muaj cov khoom tshwj xeeb hlau-wetting additives uas txo qhov nyiam ntawm cov mos mos, nplaum shale ua rau me ntsis thiab BHA balling
5. Tsis ua rau foaming
6. Biodegradable tsis muaj hydrocarbons
7. Kub tiv taus ≤200 ℃ (BHCT)
