產(chǎn)品分類
聚陰離子纖維素是一種高品質(zhì)水溶性纖維素衍生物,其商業(yè)產(chǎn)品分為兩種:PAC-L和PAC-H,皆可有效的提高水基鉆井液,其中包括淡水、海水和飽和鹽水鉆井液的年度并降低濾失量,但PAC-L沒有PAC-H那么強(qiáng)的增稠效應(yīng),PAC的一般加量為0.2%~0.6%。
PAC PAC-polyanionic cellulosic polymer is a high quality water soluble cellulose derivative.The commercial products of PAC can be divided into two categories,PAC-L and PAC-H. Both of them can effectively enhance viscosity and reduce fluid loss in water base drilling fluid inclusive saturated salt water drilling fluid system provided。 PAC-L has lesser viscosifying effect than PAC-H. The common dosage of PAC is in the range of 0.2%~0.6%.
