摘要
研究了活化重晶石在阴离子聚合物钻井液中的粘度效应和动力稳定性。实验发现,活化重晶石明显改善了阴离子聚合物钻井液的流动性,并且有抑制增稠效应,但活化重晶石加重钻井液的滤失量较高。
Serious settling instability and thickening effect were existed in mud weighted by normal barite. The density of polymer mud tested is from 1. 80 to 2. 0 g/cm3. It is shown that the fluidity and settling stability of polymer mud are improved by using chemical modification activated barite, but the fluid loss is higher than that weighted by normal barite.
