摘要/Abstract

摘要： 为解决聚合物驱后油层剩余油饱和度低且高度分散等问题,根据表面活性剂构效关系,运用相行为实验、仪器检测及物理模拟等方法,研发了一种可原位形成中相微乳液的驱油体系,并对体系中延展型表面活性剂的疏水基团碳链、亲水基团类型、环氧丙烷(PO)/环氧乙烷(EO)数量及复配表面活性剂比例等配方参数开展优化研究。结果表明:主表面活性剂是具有10个EO单元和25个PO单元的双碳链C₂₄延展型羧酸盐表面活性剂(APEC),兼具良好的疏水性能和经济性;最合适的辅表面活性剂为烷基苯磺酸盐表面活性剂(ABS),其与APEC结合后可在极低的盐度下产生超低的界面张力,呈温莎类型相行为特征且中相微乳液盐宽为0.20%,APEC与ABS复配最佳质量比为4∶6;该体系在油藏条件下可原位形成中相微乳液;水驱后原位微乳液驱采收率可达到45.9%,较弱碱三元复合驱高8.7个百分点。该研究为大庆油田聚合物驱后提高采收率新技术的研发提供了重要依据。

Abstract: To solve the problems of low residual oil saturation and high dispersion after polymer flooding,based on surfactant structure-property relationships,phase-behavior experiments,instrumental tests and physical simulation were conducted.An oil-displacement system capable of forming a middle-phase microemulsion in situ was developed,and formulation parameters optimization research was conducted,including the hydrophobic-chain lengths of the extended surfactant,the type of hydrophilic group,the numbers of propylene oxide(PO)/ethylene oxide(EO)units,and the blending ratio of mixed surfactants.Results show that the primary surfactant is a double-tailed C₂₄ extended carboxylate surfactant(APEC)containing 10 EO units and 25 PO units,which provides both favorable hydrophobic performance and cost effectiveness.The most suitable auxiliary surfactant is an alkylbenzene sulfonate surfactant(ABS).When combined with APEC,it generates ultralow interfacial tension at extremely low salinity,exhibits Winsor-type phase behavior,and provides a middle-phase microemulsion salinity window of 0.20%;the optimal mass ratio of APEC to ABS is 4∶6.The system can form a middle-phase microemulsion in situ under reservoir conditions.After waterflooding,in situ microemulsion flooding can improve recovery by 45.9%,which is 8.7 percentage points higher than weak-alkali alkaline-surfactant-polymer(ASP)flooding.This study provides an important basis for developing new post-polymer-flooding EOR technologies in Daqing Oilfield.

Key words: microemulsion flooding, phase behavior experiment, extended surfactant, middle-phase microemulsion, enhanced oil recovery(EOR)
