摘    要:摘要:利用数值模拟方法对双水平井蒸汽辅助重力泄油(SAGD)对油藏及流体的适应性及范围进行了研究,给出了SAGD对原油粘度、油层水平渗透率、垂向与水平渗透率比值、油层埋藏深度的适应性界限,制作了累积油汽比及平均日产油量随上述因素变化的关系图版,并得出上述影响因素的定量关系式,进而得到三维关系曲面。利用这些图版和关系式可以对类似油藏SAGD的开发效果及适应性进行分析预测,为同类油藏开展SAGD技术应用提供决策依据。

关 键 词:蒸汽辅助重力泄油  适应性  数值模拟  稠油

Abstract:Through numerical simulation method, the adaptability of the double horizontal well Steam Assisted Gravity Drainage (SAGD) to the reservoir and liquid parameters has been investi-gated. At the same time, the adaptability limits of SAGD to the oil viscosity, the reservoir horizontal permeability, and ratio ofvertical permeability to horizontal permeability and the depth of oil layers have been presented. The plates of the relationship be-tween cumulative oil steam ratio and the average oil production rate's varying with the above factors, the rational formulas of the co-infections by the above parameters and the three dimensional curl planes have been obtained. The exploitation effect and theadaptability of the similar reservoir can be analyzed and forecas-ted by these plates and formulas. The analyzing and forecasting results can provide the scientific foundations for developing the similar oil field with the Steam Assisted Gravity Drainage.
