摘要(Abstract)：

基于双曲递减理论,针对A气田地质条件和开采动态特征,优化可采储量评价单元,并建立各单元线性评价模型,有效评价递减阶段可采储量。应用递减阶段可采储量线性动态评价方法得到A气田加密调整前评价可采储量为20.12×10~8m~3,加密调整后评价可采储量为24.66×10~8m~3,符合气田开发规律。与以往可采储量评价方法相比,该方法直观简便、可对比性强,误差小于0.4%,不仅有利于提高工作效率,而且能有效指导气田开发综合调整。
Based on the hyperbolic curve declining theory,in the light of the geological conditions and dynamic production featuresof the gas field,by means of optimizing the evaluated units of the recoverable reserve and establishing the linear evaluating model of each unit,the recoverable reserve was effectively evaluated in the decline stage. With the help of the linear dynamic evaluating method of the recoverable reserve in the depletion stage,the recoverable reserve for Gas Field A is 20. 12 × 10~8m~3 beforethe infill adjustment; while the recoverable reserve after the infill adjustment is 24. 66 × 10~8m~3,these conditions conform to the development laws of the gas field. Comparing with the previous evaluating methods of the reserve,the developed method is more straightforward,convenient,easy to compare and its error is less than 0. 4%,thus the work efficiency is not only prone to enhance,but the combined adjustment of the gasfield exploitation can be effectivelyguided.
