本文介绍的高强度堵水剂CY 98,是针对中原油田高温高盐和高含水油藏的选择性堵水开发的 ,它是由水玻璃与改性树脂交联的聚合物形成的复合凝胶 ,其强度和弹性都比交联聚合物凝胶有很大提高 ,在两口油井的堵水作业中获得了良好的应用效果。本文报道CY 98的配方原理、基本组成、凝胶形态结构及堵剂的物化性能 :堵剂溶液流变性能、成胶条件、凝胶稳定性及凝胶动态力学性能。
This paper describes the high-strength plugging agent CY 98, is developed for the selective blocking of high temperature, high salt and high water-cut reservoirs in Zhongyuan Oilfield. It is a composite gel formed by the cross-linked polymer of water glass and modified resin , Its strength and elasticity than the crosslinked polymer gel has greatly improved, in the two oil wells water shut-off operation has been a good application effect. In this paper, the formulation principle, basic composition, gel morphology and structure and physical and chemical properties of CY 98 were reported: rheological properties of blocking solution, gelation conditions, gel stability and gel dynamic mechanical properties.
