摘要:

就聚合物分子量、分子链节中基团比例和种类等结构因素对泥浆流变性和失水造壁性的影响进行了研究。高分子量聚合物能形成较强泥浆结构，起到改进流型的作用，中分子量聚合物则具有较强降低泥浆失水的能力。分子链中吸附基和水化基因的比例以及种类对聚合物泥浆流变性和造壁性起着重要作用。

Abstract:

Influence of polymer molecular weight and structure on the rheological and wall building properties of mud is studied in laboratory.Test resultS indicate that stronger structure can be formed in mud by adding higher molecular weight polymer,while filtrati
