通过对柴达木盆地北部MB区域尤其是MB东斜坡储集层特征的综合研究,对储层四性特征及四性关系进行了精细刻画,初步建立起该区域基础参数计算模型。结合本区砂砾岩储集层特征提出了适用于该油藏特征的孔隙度解释模型,并建立了岩石粒度的预测模型。在此基础上建立粒度控制下的渗透率模型,进而提出了利用含水电阻率比值法建立的饱和度计算模型。从而形成多方法判识储层流体性质的技术。
Based on the comprehensive study on the reservoir characteristics of the MB area in the northern part of the Qaidam Basin, especially the east slope of MB, the four characteristics of the reservoir and the relationship between the four reservoirs are elaborated, and the calculation model of the basic parameters of the area is preliminarily established. Based on the characteristics of glutenite reservoirs in this area, a porosity interpretation model suitable for the reservoir characteristics is proposed and a prediction model of rock particle size is established. On this basis, the permeability model under the control of particle size is established, and then the saturation calculation model established by the ratio of water resistivity is proposed. Thus forming a multi-method technology to identify reservoir fluid properties.
