摘要: 为了开发出一种新型低成本、高性能的深部液流转向与调驱剂,利用现代插层复合技术,对目前调剖调驱中常用的聚丙烯酰胺进行聚合物合成改性,采用原位聚合合成方法,研制了一种新型插层聚合物凝胶转向剂,其插层聚合物、交联剂和助剂的浓度分别为0.15% ~0.35% 、0.15% ~0.22% 、0.005% ~0.220% ,其成胶时间为6~100 h可调。实验研究表明,该插层聚合物凝胶转向剂具有较好的抗剪切性、与油田水的配伍性、热稳定性及封堵性能,可满足油田条件下的深部调驱和改善水驱开发效果的需要。其与现有的常规聚合物体系相比成本可降低10% ~15% ,表明该体系具有良好的应用前景。

Abstract: This study aims to develop a novel cost-effective high-performance deep fluid diversion and profile control-displacement agent. The synthesis and modification of polyacrylamide, a polymer presently commonly used in profile control and oil displacement, is carried out using the modern intercalation compounding technique. A new intercalated polymer gel diversion agent is developed by in situ polymerization. The concentrations of intercalated polymer, cross linker, and additive agent are 0.15% -0.35%, 0.15% -0.22%, and 0.005% -0.22%, respectively; the gelation time is adjustable between 6 h and 100 h. Experiment data show that the obtained intercalated polymer gel type deep fluid diversion agent has good shear resistance, high compatibility with oilfield water, thermal stability, and plugging performance. It can meet the need of depth profile control under field conditions and improve the waterflooding development effect. Compared with the existing polymer system, the proposed polymer system has reduced cost by 10% -15%, indicating its good application prospects.

Key words: Intercalated polymer gel, diversion agent, cross linker, gel property, low cost
