摘　　要：在考察了一种室内高效延缓交联剂配方的性能的基础上,得到的基本配方为:有机酸A和CrCl3,两者的最佳摩尔比为5:1,其使用浓度为0.01%～0.02%.应用该交联剂形成的冻胶堵剂可泵性好,交联时间可控,成胶后强度高、对人造岩心封堵率大。On the basis of investigating the properties performance of a high efficiency retarding crosslinking agent in the laboratory, the obtained basic formula includes organic acid A and CrCl3 with optimized molar ratio being 5：1 and recommendable concentration being 0.01%-0. 02 %. The crosslinked gel plugging agent formed by the crosslinking agent characterizes easy pumping, controllable crosslinking time, high gelation strength and plugging efficiency for synthetic core,which are quite promising for deep-zone profile modification.
