2. Parameters
The polyvinyl alcohol additive contributes to cost savings and has shown no retardation effect on the cement setting time. Therefore, it enables fast and cost-efficient oil well construction.
when pva224S mixed with cement powder, water, dispersant and defoamer, will prevent fluid loss to the formation in cementing operations. it is an excellent binder, reduces fluid loss, reduces water production in the cementing process and compatible with other cement additives. It contributes to cost savings by enabling fast and cost-efficient oil well construction and has shown no retardation effect on the cement setting time
