Abstract: The producing degree of oil in place is one of the important indexes in oilfield development. The two-section thickness gauge algorithm has been used over a long period of time, but it is limited only to the artificial water-flooded oil reservoirs and the reservoirs that can be tested for water-absorbing section and liquid-producing section. Few people pay attention to the algorithm for producing degree of geological reserves from other types of oil driving or reservoirs. There is a variety of geological reserves thanks to certainty and influential factors, leading to complexity of producing degree of geological reserves. Use of production data in a certain period for calculation of recoverable reserves can reflect the waves of producing geological reserves during that period of time. Then, the producing degree of geological reserves can be calculated on the basis of oil driving efficiency. This method is simple, efficient and convenient. The actual calculation cases confirm that this method is feasible. The article also discusses the suitability of this method and the related issues concerned at the time of calculation.

摘要： 地质储量动用程度是油田开发的重要指标之一，长期以来采用两剖面厚度计算法，但仅限于人工水驱油 藏，以及能测吸水剖面和产液剖面的油藏，其他驱动类型或油藏类型的地质储量动用程度的计算方法则很少有人关注。 地质储量具有不确定性及影响因素的多样性，造成了地质储量动用程度的复杂性。应用某阶段的生产数据计算可采储量， 可反映当期动用地质储量波及情况，再结合驱油效率计算地质储量动用程度，方法简捷、有效、方便。通过实例计算 验证了该方法的可行性，并讨论了该方法的适应性与计算时需注意的问题。
