Recoverable reserve calculation for fractured buried hill reservoir.

方法 应用经验公式法、水驱特征曲线法、递减曲线法及数值模拟法对裂缝性潜山油藏进行可采储量计算研究。目的 确定油藏的最终采收率 ,评价开发效果 ,并为同类油藏的合理开发提供理论依据。结果 根据油藏实际动态数据之间的统计规律 ,东胜堡潜山油藏可采储量为 5 0 0× 10 4 t左右 ,采收率为 37 2 %。结论 计算可采储量的方法较多 ,应充分考虑油藏各种地质、开发动态实际因素 。

Method\ Recovery reserve calculation for fractured buried-hill reservoirs are studied by applying the following methods, including empirical equation, water-drive characteristics curves, decline curves and numerical simulation. Purpose\ To determine final recovery and evaluate recovery effect, and provide theory basis for reasonable development of likewise reservoirs. Result\ As per statistical pattern of practical dynamic data, it is suitable and reliable to estimate that the recoverable reserve for Dongshengpu buried hill will be ca.5×10\+6 t at the recovery rate of 37.2%. Conclusion\ Enough consideration should be given to various geologic, development status factors in selecting recoverable reserve calculation method. \;
