综合运用实测物性、测井解释物性、试油等资料，分别应用分布函数曲线法、测试法、试油法求取饶阳凹陷南部古近系中深层不同深度段的有效储层物性下限，并对物性下限与深度的关系进行了回归拟合。在此基础上，引入孔隙度差值，结合饶阳凹陷南部古近系中深层储层的沉积特征、成岩作用特征及地层压力特征分析，探讨了有效储层发育的控制因素。结果显示：研究区辫状河三角洲前缘水下分流河道、河口坝沉积微相有利于有效储层的发育，而席状砂、水下分流间湾砂体有效储层发育较少，储层物性较差；厚度大于3 m 的砂体有利于有效储层的发育。研究表明：成岩作用对储层的影响主要表现为压实作用和胶结作用使储层物性降低，而溶蚀作用使储层形成次生孔隙、提高储集物性；地层超压的存在促进有效储层的发育。

Based on measured properties ,such as physical properties of log interpretation an d oil production tests ,the petrophysical parameter cutoff and depth of medium‐deep effective reservoirs of Paleogene in the southern Raoyang sag are determined by distribution function curve method , test method ,oil production test method ,and the fitting formula of petrophysical parameters .Further ,the porosity difference is introduced combining with the analysis on the characteristics of sediments , diagenesis ,and reservoir pressure of the medium‐deep reservoirs in southern Raoyang sag ; and the controlling factors of effective reservoirs are discussed . The results show that the subaqueous distributary channel and estuary bar of fan delta front subfacies are suitable for the grow th of effective reservoirs ;while the properties of delta‐front sheet sand and inter distributary bays are weak ,where less effective reservoirs are developed .When the thickness of sand is greater than 3 meters ,the sand could be developed into an effective reservoir .Compaction and cementation are the main factors to decrease porosity and permeability of reservoirs ;while dissolution increases the secondary pores ,and in turn ,makes the physical property of reservoir better . The existence of overpressure promotes the development of effective reservoirs .
