摘要
海上某油田的湖相碳酸岩油藏沉积范围小、厚度薄、横向变化快、地震资料品质差、储层难以识别,致使常规容积法计算储量的准确度受到了限制。利用永久式井下压力计监测井底压力,在不影响油井正常生产的情况下,应用压降曲线法计算油藏动态储量,取得了较好效果,为该油田下一步调整提供可靠的储量基础。
There is a lake facies carbonate reservoir in an offshore oilfield,the depositional area of which is very small,the thickness of which is small and changes horizontally and greatly,the seismic quality of which is poor,and the oil-bearing strata identification is difficult,so that the reserves of which can not be accurately calculated with conventional volumetric method.Monitoring pressure variation with permanent downhole pressure gauge under condition of non-influence of normal production,dynamic reserves of which is calculated from the pressure drawdown curve measured by the permanent downhole pressure gauge,and reliable reserves data are provided for further adjustment of the field development.
