求翻译：为了对储层进行准确的评估预测，以解决油气开采的实际需要，大量学者认识到提供定量且精准的储集参数（如孔隙度、渗透率、含油气饱和度等）的重要性，从而建立了数学公式和经验模型。但公式中的某些参数在实际应用中往往很难确定。是什么意思？

Accurate assessment and prediction of reservoir in order to address the actual needs of the oil and gas exploration, a large number of scholars recognize that provide quantitative and accurate reservoir parameters (such as porosity, permeability, including the importance of oil and gas saturation, e

In order to make an accurate reservoir forecast, in order to solve the oil and gas exploitation, the actual need for a large scholars recognize that quantitative and precise set of parameters, such as reservoir porosity, permeability, and oil and gas saturation, etc. ) to establish the importance of

In order to carries on the accurate appraisal to the reservoir to forecast, solves the oil gas mining actual need, the massive scholars realized to provides the quota also the fine accurate accumulation parameter (for example porosity, penetration coefficient, including oil gas degree of saturation

In order to accurately evaluate reservoir prediction, to address the actual needs of the oil and gas production, a large number of scholars recognize that provide quantitative and precise reservoir parameters (such as porosity, permeability, saturation of the hydrocarbon and other) importance, thus
