| 摘 要： | 在前人研究的基础上，对一种异常高压油气藏地质储量计算及动态预测的物质平衡新方法进行了分析和应用。与传统物质平衡方法不同，它无需对流体组分、压力梯度、水侵以及定孔隙体积等作限制，尤其是考虑了挥发油和反凝析的影响。通过引入挥发油和凝析油气体系的相平衡计算，使这种方法不仅适用于一般油气藏，也适用于挥发油藏和异常高压凝析气藏的动态预测和储量计算。通过实例分析，证明了上述方法对异常高压凝析气藏的适应性和准确性。

| Abstract: | Based on the previous research, the author made extensive analysis and application appraisements are made about a new material balance method of super high-pressure oil (gas) reservoirs to calculate reserves and predict performance. Differ from the traditional material balance; this method needs no restrictions on fluid composition, pressure gradient, water influx or constant pore volume assumption. Especially, the new method accounts for volatilized-oil and retrograde condensate. Through bringing in the volatilized-oil and oil-gas phases equilibrium calculation, it is applicable to the full range of fluids, including ordinary reservoirs, volatile-oils and super high pressure gas condensate reservoirs. By means of case study, it is proved to be adaptable and accurate to super high pressure condensate reservoirs. |
