摘要
利用测井资料与仅有的地质资料相结合。研究其储层的岩性、物性、电性、含油气性及其相互间的关系，从而建立起测井信息与地质信息的对应关系。根据这些关系，由局部扩展到整个区块，进行逐井逐层段分析运算，从而获得比较准确的区块目的层储集参量值。储集层参量主要包括泥质含量、岩石骨架内各类岩性的相对含量、粒度中值以及储层的孔隙度、渗透率、含油饱和度和有效厚度等。这些参量在纵向上和平面上的分布规律直接反映了储层的非均质特性、孔隙性和渗透性的变化特征，以及油气水的分布特征。
By making use of log data and geological information, analyzing lithologic characteristics, the physical and electric behavior, the oil-gas bearing potential of reservoir rocks as well as their relations with each other, it is possible to establish the corresponding relations between log data and geological information. According to these relations, every well and every formation was analyzed and calculated so as to obtain precise reservoir parameters of the target formation in a block. The most important parameters include: shallness, mineral ingredients in the rock framework, the mean value of grain size, porosity, permeability .oil-saturation and the available thickness of the reservoir. The vertical andplanar distribution of the parameters reveals directly the variation property of reservoir's heterogeneity, porosity and permeability as well as oil and gas distribution.
