Dispersing agent for oil well cement and application thereof
The invention relates to a dispersing agent for oil well cement and application thereof. The dispersing agent for oil well cement includes a polymer having a structural unit A, wherein the structural unit A is derived from an aryl sulfonic acid monomer. According to the invention, the cross-linking phenomenon when a conventional polycarboxylic acid dispersing agent is compounded with a fluid loss agent and a retarder is well solved, and the dispersing agent has a good dispersing effect on oil well cement.
本发明涉及一种油井水泥用分散剂及其应用。所述油井水泥用分散剂包含具有结构单元A的聚合物，其中所述结构单元A衍生于芳香基磺酸单体。本发明很好解决了常规聚羧酸分散剂与降失水剂、缓凝剂复配时的交联现象，对油井水泥具有较好的分散效果。
