普通稠油油藏蒸汽吞吐后期注汽参数优化设计方法

Optimization of Steam Injection Parameters at Late Stage of Huff and Puff in Ordinary Heavy Oil Reservoirs

利用经济平衡点、日收益及动态分析方法 ,进行了稠油油藏蒸汽吞吐后期的注汽参数确定。在分析普通稠油油藏蒸汽吞吐后期生产特点的基础上 ,以提高吞吐后期的经济效益为目标 ,通过多元回归确定了经济平衡点 ,研究出主要注汽参数的设计方法。

Steam injection parameters are optimized at late stage of huff and puff in heavy oil reservoirs by using economic balance point, daily revenue and dynamic analysis methods. The production characteristics are analyzed. Economic balance point is determined through multiple regression with improvement of economic benefits as the goal. Design methods of main steam injection parameters are developed.
