利用水驱储量预测可采储量的简便方法

油田可采储量是评价石油储量利用程度的重要指标，是油田开发分析的重要依据。现行的油田可采储量计算方法在实际应用中还存在一定的局限性。根据注水开发油田的储量构成特点，考虑油藏基本特征和储量动用状况，提出了依据一次采收率、水驱油效率、井网控制储量、水驱储量预测可采储量和采收率的方法。该方法可对小层可采储量进行计算评价，能对正在进行或将要进行重大调整、治理油藏的可采储量进行分析预测。实践证明，该方法可以深

The Handy Method of Forecasting Recoverable Reserves According to Waterfiooding Reserves

The recoverable reserves in the oilfield is the important index for reservoir evaluation and the basis for development analysis. The active method of calculating rewverable reserves is certainly restrictive in ac tual execution. In this paper, according to reserves structure of water-drive reservoir, considering the basic charac teristics of reservoir and the utilization of reserves, a new methed is proposed for forecasting recoverable reserve and recovery based on the flowing recovery, waterflooding efficiency, well network control reserves and water fldriing reserve. It can evaluate and calculate recoverable reserves of small formations, and can analysis and pre dict recovrable reserves of reservoirs being going to be adjusted and governed. It pointed out that this methed is convenient and haible,and it can be used to deePen reservoir valuation, to analysis reservoir rmurce quantita tively and to provide scientific foundation for adjusting and tapping the potentialities of reservoirs.
