物质平衡法分区计算定容气藏动储量和压力

定容气藏的动态储量和地层压力获取方法尽管很多。但要在油田紧张的生产情况下准确计算却并不容易，尤其在测试地层压力时要求全区整体关井，并达到一定的时间，测试点尽量多的情况下。利用物质平衡法分区计算了定容气藏动态储量，并结合弹性二相法联立计算了不关井条件下的地层压力。现场数据说明，按照压力系统和非均质性分区计算动态储量比全区整体计算更接近真实的结果，误差更小；用物质平衡方法计算不关井条件下的地层压力，误差较小，比较实用。

Multi-Region Calculation of Dynamic Reserve and Pressure of Constant Volume Reservoirs Using Material Balance

Many different calculation methods for calculating the dynamic reserve and pressure of the constant volume reservoir, while it is difficulty to obtain the accurate calculation during production, especially it requires that all wells shut-in, certain time for pressure build-up and multiple pressure measure locations. The dynamic reserve of the constant volume reservoir is calculated using material balance, and combined with elastic two-phase the formation pressure is calculated without well shut-in. The field data indicate that, in calculating the dynamic reserves, multi-region calculation according to different pressure system and heterogeneity is better than that of by assuming the whole reservoir as one region, the formation pressure calculation without wells shut-in is practical and reliable.
