摘要: 凝胶堵水工艺作为塔河油田开发中后期提高采收率主要技术手段,随油藏温度、矿化度的不断升高,单一凝胶体系堵水有效程度低,其体系研发及使用方法亟需优化改善。为此,以自主研发的两套耐高温高矿化度、耐稀释堵水体系为研究基础,通过开展红外、热重、流变性等分析,对凝胶材料的耐稀释性、配伍性进行了系统的评价,同时基于岩芯实验模拟提出两种凝胶体系协同使用,复合堵水的动态封堵模式,进一步提高动态封堵率和封堵效果。实验表明,两种凝胶体系可应用于140℃高温条件,在24×104 mg/L矿化度水中具有较好的耐稀释性,在确保两种凝胶具有较好配伍性的同时协同使用,其优异的耐冲刷性使协同堵水封堵率大于99%。研究表明,配伍性较好的不同凝胶体系联合堵水,在高温高盐油藏具有较好的应用潜力。

Abstract: Gel water plugging is the main technical method for recovery in the middle and late development of Tahe Oilfield. As the reservoir temperature and salinity continue to increase, the water plugging effectiveness of a single gel system is low, and its system development and use of water plugging materials urgently need to be optimized and improved. In this regard, this paper is based on the research of two independently developed sets of high temperature resistance, high salinity and dilution resistance water plugging systems. Through infrared, thermos-gravimeter, rheology and other analyses, the dilution resistance and compatibility of gel materials are systematically evaluated. At the same time, based on core experimental simulation, a dynamic plugging model for the collaborative application of the two gel systems is proposed to compound water plugging to further improve the dynamic plugging rate and plugging effect. Results show that the two gel systems can be applied to high temperature conditions of 140 ℃ and have good dilution resistance in water with a salinity of 24×104 mg/L. While ensuring good compatibility of the two gels, they are used synergistically. Their excellent erosion resistance makes the collaborative water plugging rate greater than 99%. Studies have shown that different gel systems with good compatibility can combine to block water and have good application potential in high temperature and high salinity environments.

Key words: plugging agent, high temperature and high salinity, dilution resistance, compatibility, synergistic water plugging
