In recent years, with the further development of old oilfields, in order to further improve the oil recovery, they must be conformance controlled. Among various types of conformance control methods, polymer gels composed of polymers and crosslinkers have attracted widespread attention because of their efficiency and low costs. Among them, organic chromium gels with their good formation adaptability and high stability have been fully developed in recent decades. This review introduces the different types of polymers and crosslinkers used in the preparation of organic chromium gels, and the mechanisms of affecting their performance are analyzed. On this basis, the organic chromium gels for different formation conditions are introduced, including nanoparticle-reinforced and compound organic chromium gels. At the same time, evaluation methods of organic chromium gels are introduced, while the focus is on the in-situ measurement method (mirco-rheology) of gel formation time developed in recent decades. Based on the currently developed organic chromium gel and the analysis of the development status in oilfields, future directions like the use of supramolecular organic chromium gel and shear organic chromium gel are suggested.

近年来，随着老油田的进一步发展，为了进一步提高采油率，必须对其进行一致性控制。在各种类型的一致性控制方法中，由聚合物和交联剂组成的聚合物凝胶由于其效率和低成本而引起了广泛的关注。其中，近几十年来已经充分开发了具有良好的形成适应性和高稳定性的有机铬凝胶。这篇综述介绍了用于制备有机铬凝胶的不同类型的聚合物和交联剂，并分析了影响其性能的机理。在此基础上，介绍了适用于不同形成条件的有机铬凝胶，包括纳米颗粒增强和复合有机铬凝胶。同时，介绍了有机铬凝胶的评估方法，重点是近几十年来开发的凝胶形成时间的原位测量方法（微流变学）。根据目前开发的有机铬凝胶和油田的发展状况，提出了超分子有机铬凝胶和剪切有机铬凝胶的应用未来方向。
