product introduction
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. | ||||||
