喇嘛甸油田三元复合驱表活剂解堵增注技术研究

Study of the Surfactant Broken and Increase the Injection Technology on Lamadian Oil Field ASP Flooding Tentative

随着三元复合驱油体系注入体积的增加,注入压力高、高渗透厚油层大段不吸水等问题日益突显。为缓解注采关系矛盾,现场采取表活剂解堵增注措施并取得较好的效果。以现场取样化验分析、措施效果统计分析为基础,系统地分析了三元复合驱油层堵塞机理及规律,搞清了适用于三元复合驱的表活剂解堵增注技术机理,优化了药剂用量计算方法及适用于三元复合驱的表活剂解堵增注工艺方式。该项研究为三元复合驱油试验实施表活剂解堵增注措施提供理论依据。

With the injection of ASP flooding system size increases,the injection pressure Increased、large section of high permeability oil-bearing do not absorb water and other problems appearance.To ease the contradiction of the relationship between injection and recovery.the measure of surfactant broken in the field and taking the better results is adopt.Basised on laboratory and analyzes the sampling,the effect of measure is statistics and analyzed,the mechanism and laws of plugging in reservoir systematically are analyzed.The mechanism of surfactant broken is clarified and increased the injection,optimized the reagent calculation method and applied asp flooding watch live agent solution plugging increase note craft ways.The study for ternary recognition test implementation watch live agent solution plugging increase note provide theoretical basis for measures.
