摘要
为了提高凝析气藏油气采收率 ,通常采用目前最有效的循环注气保持地层压力的开采方式。在此开采方式下 ,直接采用气藏物质平衡方程进行地质储量计算将出现很大偏差。针对这种情况 ,将气藏物质平衡方程进行了改进 ,得到凝析气藏在注气开发方式下的物质平衡方程。
The most effective production scheme of cyclic gas injection for keeping formation pressure at present is adopted generally to improve oilgas recovery in the condensate gas reservoir. Large deviation will appear if material balance equation of the gas reservoir for calculating OIP is used directly in this production scheme. So the equation is improved, then the material balance equation in the gas injection development for the condensate gas reservoir is obtained.
