摘要

摘要: 定量表征孔渗和饱和度的三维空间分布是孔隙型碳酸盐岩油藏开发的技术难题。为建立可靠的孔隙型碳酸盐岩油藏地质模型，以扎格罗斯盆地F油藏为原型，研究并提出了沉积相耦合岩石物理类型的建模方法。该方法在地质研究的基础上，通过井-震联合建立沉积相模型；再以沉积相控制建立孔隙度和岩石物理类型三维分布模型；然后基于岩石物理类型控制下的孔渗关系数学模型和饱和度数学模型，采用确定性建模方法，建立渗透率和饱和度三维分布模型。模型检验表明，该方法建立的地质模型可靠，为F油藏的有效开发奠定了坚实的地质基础，可为该类油藏的地质建模提供指导。

Abstract: The quantitative characterization of petrophysical properties such as porosity, permeability, and saturation in 3D space has been a technical problem for the development of porous carbonate reservoirs. In order to establish a reliable geological model of porous carbonate reservoirs, taking reservoir F in the Zagros Basin as a prototype, a geological modeling method based on sedimentary facies coupled rock type was studied and put forward. Based on geological research, we combined well logging data with seismic data, and established a sedimentary facies model. Controlled by the sedimentary facies model, 3D distribution models of porosity and rock type were built. Then, based on the porosity-permeability mathematical model and saturation height function controlled by rock type, 3D permeability and water saturation distribution models were established by using deterministic modeling method. The results showed that the geological model established by using the proposed method was reliable, which laid a solid geological foundation for the development of reservoir F, and the method proposed in this paper could provide guidance for the geological modeling of this kind of reservoir.
