摘要
结合辽河超常规稠油油田的生产实际,对蒸汽辅助重力泄油及其改进方式(蒸汽和气体联合泄油、单井蒸汽辅助重力泄油以及强化蒸汽辅助重力泄油)的开采机理进行了研究,并对以上几种开发方式进行了模拟,将模拟结果与蒸汽吞吐和蒸汽驱开发方式的模拟结果进行了比较和方式优选.优选结果认为:蒸汽辅助重力泄油及强化蒸汽辅助重力泄油是开采超常规稠油油藏较为有效的开发方式;在超常规稠油开发早期,应采用蒸汽辅助重力泄油,后期应转为强化蒸汽辅助重力泄油.在此基础上,根据现场调研及数值模拟方法研究,确定了采用蒸汽辅助重力泄油和强化蒸汽辅助重力泄油进行超常规稠油开发的技术指标并进行了参数优化,分析了蒸汽辅助重力泄油的适应性.研究结果对超常规稠油油藏开发具有一定的指导意义.
According to the production practice in Liaohe oilfield, this paper has imitated the steam_assisted gravity drainage and its improved methods, and the simulation results are compared with those of steam soak and steam drive, with the option of development operations optimized. Based on the option, the steam_assisted gravity drainage and enhanced steam_assisted gravity drainage can be considered effective exploitation methods for super heavy oil reservoir. In the early exploitation stage of super heavy oil, the steam_assisted gravity drainage should be applied, and then the enhanced steam_assisted gravity drainage in the late stage. Thereby the technical standards of super heavy oil exploitation by steam_assisted and enhanced steam_assisted gravity drainage can be established according to field investigation and numerical simulation. Furthermore, the parameters are optimized, and the adaptability of steam_assisted gravity drainage is analyzed. All these results may offer a guide to exploitation of super oil reservoir.
