针对高温高盐油藏注气开发过程中易发生气窜,严重影响开发效果的问题,将长碳链羟磺基甜菜碱和短碳链羟磺基甜菜碱按照2∶1的质量比复合构建耐温耐盐起泡剂MHSB12,利用该起泡剂产生的泡沫调控气体流度。通过临界胶束质量分数测定、界面流变性测定、静态吸附量测定、体相泡沫性能评价以及在多孔介质中的生泡能力评价等实验,全面对比了MHSB12在盐含量为11.19×104、22.38×104 mg/L的2种模拟地层水中的性能。研究表明:在高盐条件下,MHSB12临界胶束质量分数更低,表面扩张模量更高,起泡性能及稳定泡沫能力更强;当MHSB12质量分数为1%时,起泡剂溶液满足提高采收率用表面活性剂吸附标准,适用于塔里木油田深层碎屑岩及同类油藏;在MHSB12质量分数相同的条件下,含盐量较高的起泡剂溶液吸附能力略低;与低盐条件相比,高盐条件下MHSB12在岩心中的流度调控能力明显弱。该研究对起泡剂的筛选与评价以及油气田提高采收率具有实践指导意义。
In order to address the issue of gas channeling during the development of high-temperature and high-salinity oil reservoirs, which seriously affects the development effect, the long carbon chain hydroxysulfobetaine and the short carbon chain hydroxysulfobetaine were compounded according to the mass ratio of 2∶1 to construct a temperature-resistant and salt-resistant foaming agent MHSB12, and the gas mobility was controlled by the foam generated by this foaming agent. The performance of MHSB12 in two kinds of simulated formation water with salt content of 11.19×104 and 22.38×104 mg/L was comprehensively compared by conducting experiments such as determination of critical micelle mass fraction, interfacial rheology and static adsorption capacity, evaluation of bulk phase foam performance foaming capacity in porous media. The results show that under high salt conditions, MHSB12 has lower critical micelle mass fraction, higher surface expansion modulus, stronger foaming performance and foam stability. When the mass fraction of MHSB12 is 1%, the foaming agent solution meets the surfactant adsorption standard for enhanced oil recovery, which is suitable for deep clastic rocks in Tarim Oilfield and other similar reservoirs. Under the same mass fraction of MHSB12, the adsorption capacity of foaming agent solution with higher salt content is slightly lower. Compared with low salt conditions, the mobility control ability of MHSB12 in the core under high salt conditions is significantly weaker. Hence the evaluation of flow experiment should be paid attention to when screening foaming agents for field use. The study has practical guiding significance for screening foaming and evaluating foaming agents forenhancing oil/gas recovery.
