The success of chemical enhanced oil recovery (cEOR) is significantly dependent on the type of reservoir and its pressure and temperature conditions. The recovery of heavy oil from carbonate reservoir using cEOR method is still challenging because of its highly complex internal structures and high pressure–high temperature (HPHT) conditions. This research work is the first account of the use of AGA‐97 (viscoelastic surfactant [VES)) along with a chelating agent diethylene triamine penta acetic acid (DTPA) for their application in cEOR method in heavy‐oil‐carbonate reservoirs. Several core flooding experiments were carried out to ascertain the effectiveness of the VES AGA‐97 and chelating agent for cEOR method. The effect of VES on viscosity and interfacial tension was also studied with varying concentration, temperature, and time. The thermal stability of VES was analyzed with the help of thermogravimetric analysis, nuclear magnetic resonance (NMR) and Fourier‐transform infrared spectroscopy. VES AGA‐97 was found to have high thermal stability in short‐term aging. The static adsorption and dynamic adsorption of VES AGA‐97 was studied with the help of total organic carbon analysis. After all the analysis, it was found that VES AGA‐97 and DTPA can be effectively used for cEOR method in carbonate reservoir at HPHT conditions, and the total additional oil recovery of 5.82–9.64% may be achieved.

贵重粘弹性表面活性剂和螯合剂在高压-高温碳酸盐岩油藏中提高稠油采收率的实验研究
化学强化采油（cEOR）的成功很大程度上取决于油藏类型及其压力和温度条件。使用cEOR方法从碳酸盐岩油藏中开采重油仍然具有挑战性，因为它的内部结构非常复杂，而且高压-高温（HPHT）条件也很复杂。这项研究工作是首次将AGA-97（粘弹性表面活性剂[VES]）与螯合剂二亚乙基三胺五乙酸（DTPA）一起用于重油碳酸盐油藏的cEOR方法。进行了几次岩心驱油实验，以确定VES AGA-97和螯合剂对cEOR方法的有效性。还研究了在浓度，温度和时间变化的情况下VES对粘度和界面张力的影响。借助热重分析，核磁共振（NMR）和傅立叶变换红外光谱法分析了VES的热稳定性。发现VES AGA-97在短期老化中具有很高的热稳定性。借助总有机碳分析研究了VES AGA-97的静态吸附和动态吸附。经过所有分析，发现VES AGA-97和DTPA可以有效地用于HPHT条件下碳酸盐岩储层中的cEOR方法，并且可以实现5.82–9.64％的总额外采油量。借助总有机碳分析研究了VES AGA-97的静态吸附和动态吸附。经过所有分析，发现VES AGA-97和DTPA可以有效地用于HPHT条件下碳酸盐岩储层中的cEOR方法，并且可以实现5.82–9.64％的总额外采油量。借助总有机碳分析研究了VES AGA-97的静态吸附和动态吸附。经过所有分析，发现VES AGA-97和DTPA可以有效地用于HPHT条件下碳酸盐岩油藏中的cEOR方法，并且可以实现5.82–9.64％的总额外采油量。
