在油气勘探开发中，科学决策的依据是由各种概念模型或数学模型给出的有关油气藏规模和空间分布的预测及储量的合理估算。根据油气勘探中、后期阶段决策的特点，把决策分为战略决策和管理决策，重点讨论了分形几何在油气藏规模分布和空间分布预测以支持战略决策方面的应用前景和地质统计学在储量计算、风险评价以支持管理决策方面的应用前景，并针对我国东部盆地处于勘探开发的中、后期，建议今后应加强有关方面的应用研究。
In oil and gas exploration and development, the scientific decision-making is based on the prediction of reservoir size and spatial distribution and the reasonable estimation of reserves given by various conceptual models or mathematical models. According to the characteristics of decision-making in the middle and late stages of oil and gas exploration, the decision-making is divided into strategic decision-making and management decision-making. The application of fractal geometry in reservoir size distribution and spatial distribution prediction to support strategic decision-making is discussed. , Risk assessment in order to support the application of management decision-making prospects, and for the eastern basin in the exploration and development in the late, it is recommended that in the future should strengthen the relevant aspects of applied research.
