摘　　要：常规的生产数据分析技术主要针对定容封闭油藏,在进行溶解气驱油藏递减分析时适用性变差,为提高解释精度,根据溶解气驱油藏水平井的渗流特点,建立渗流模型,利用点源法,对水平井的压力分布叠加以及处理,引入拟时间,结合物质平衡校正,通过数值反演及计算机编程得到现代产能递减Blasingame理论图版。利用图版和曲线特征,基于现代产能分析方法理论进行实例分析,可以直观地进行溶解气驱油藏生产数据分析,满足工程实际要求,对于指导油田的开发开采具有重要意义。The conventional production data analysis technique is mainly aimed at the closed reservoir with constant volume,not fitness for dissolved gas drive reservoir. In order to improve interpretation accuracy,according to the seepage characteristics in the solution gas drive reservoir of the horizontal well,the percolation model is established,and by using point source method,superposition and treatment of pressure distribution for horizontal well are conducted,and introduced pseudo time and combined with the material balance,the modern decreasing production theory plate of Blasingame has been gained by numerical inversion and computer programming. By usage of plates and curves,the actual example is analyzed based on theory of the modern production method,which can visually analyze production data of the dissolved gas drive reservoir,meet the practical requirement of engineering,and have a great significance for guiding oilfield development exploitation.
