分子结构对复合离子聚合物降失水剂性能的影响

通过钻井液性能实验和滚动回收实验，对复合离子聚合物降失水剂进行了性能评价，探讨常温下复合离子聚合物降失水剂分子结构与降失水效果、抑制性的关系。降失水剂的分子量大小，阴、阳、非离子基团比例对降失水效果、抑制性有不同程度的影响；无论在淡水钻井液还是盐水钻井液中，在非离子基团含量相同的条件下，阳离子含量愈低，阴离子含量愈高，降失水效果愈好；在阴离子含量相同的条件下，阳离子含量愈低，非离子含量愈高，降失水

Effect of Molecular Structure on Polymer Fluid Loss Additive Performance with Compound Lon

Through drilling fluid performance test and rolling recovery test,the paper evaluates the performance of polymer fluid loss additive with compound lon,discusses the relation of molecular structure with fluid loss result and inhibitive at ordinary temperature.Magnitude of molecular weight on fluid loss additive,and proportion of anion,cation and nonion radical have effect on fluid loss result and inhibitive.
