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，该方法可以深化油藏认识，对油藏潜力进行量化分析，为调整挖潜提供科学依据。
The recoverable reserves of oilfields are an important index to evaluate the utilization of petroleum reserves and are the important basis for oilfield development and analysis. The existing calculation method of recoverable reserves in oilfields still has some limitations in practical application. According to the characteristics of reservoir reserves in oilfield development and taking into account the basic characteristics of reservoirs and the utilization of reserves, a method of predicting recoverable reserves and recovery rates based on primary recovery rate, water flooding efficiency, well control reserves and waterflooding reserves is proposed . The method can calculate and evaluate the recoverable reserves of small layers, and can analyze and predict the recoverable reserves undergoing or to be greatly adjusted and controlling the reservoir. Practice has proved that this method can deepen the understanding of reservoirs and quantify the potential of reservoirs, providing a scientific basis for adjusting and tapping potential.
