uniaxial pressure sealant for drilling fluid
definition | Uniaxial pressure sealant for drilling fluid (one-way pressure sealant for drilling fluid) is a compound product of several natural fibers, filling particles and some additives by special technology treatment according to appropriate ratio. It has good effection on plugging the leakage of stratum under the action of uniaxial pressure(one-way pressure). Convenient use, good compatibility and no affection on the performance of the mud. | ||||||

feature | High speed and good effect on plugging the leakage of pore and small crack. | ||
| Rapidly form a impervious shield with a certain strength preventing liquid and solid into reservoir in order to protect the reservoir undamaged. | ||
| Significantly reduce the filtrate loss of mud and no affect on the Rheological properties of mud.excellent performance of high temperature. | ||
| No affection by electrolyte pollution, harmless and non-toxic | ||
Recommended dosage | 1 ~ 2% for preventing leakage | ||
| 2 ~ 4% for plugging pores and small cracks and protecting reservoir | ||
| 4 ~ 6% for plugging the serious leakage layer | ||
packing | 25kg/bag | ||
attention | Store in dry and cool place, avoid sun exposure and prevent from package damaged and damp |
walnut shell granule & powder
definition | Walnut shell is processed into different specifications Of particle by absorbing, crushing and screening. | |
