本文报道了改性树脂交联的聚合物与水玻璃形成的复合凝胶堵水剂CY 98的岩心封堵实验结果 ,简述了在中原濮城油田两口超高含水油井用于堵水的良好效果。该堵剂有一定的选择性 ,堵水率高 ,承压强度大 ,耐冲刷性能好 ,与封口剂配合使用时封堵有效期可达到冻胶型堵剂的三倍以上。
This paper reports the results of core plugging test of the composite gel plugging agent CY 98 formed by modified resin cross-linked polymer and water glass. The results of the core plugging experiments on two wells in Pucheng Oilfield are described. effect. The blocking agent has certain selectivity, high water blocking rate, large bearing strength, good erosion resistance, and the sealing agent can be used in conjunction with the plugging period of up to three times more than the gel type plugging agent.
