Static reservoir modeling for optimizing the strategies of hydrocarbon field developments using seismic data and well logs is the focus of this study. The static reservoir modeling is conducted to estimate reservoir properties of the Upper Sarvak formation in one of the offshore oil fields in the Persian Gulf. The Sarvak Formation with middle Cretaceous age is considered as one of the most important productive oil and gas reservoirs in the south and southwest Iran. In this study, we have used seven well logs and 3D seismic data in geostatistical methods for reservoir modeling. The petrophysical parameters such as effective porosity and permeability have been estimated, using the sequential Gaussian simulation method. The evaluation of petrophysical parameters in the reservoir layer shows that the mean effective porosity and permeability are 12.75% and 51.5 mD, respectively. The evaluation of petrophysical parameters from the reservoir characteristic viewpoint demonstrated that a zone called A2 has the best reservoir quality. The well-log validation with core data has been achieved by a cross-validation method. The correlation coefficients derived from the permeability and core data are 86% and 81% for wells w-01 and w-03, respectively, which show that the Sequence Gaussian Simulation is an acceptable method. The result of this study can provide useful information for the development of hydrocarbon exploration studies and reservoir simulation models in this oil field.

使用地质统计学方法进行静态油藏建模：以海上油田 Sarvak 组为例

使用地震数据和测井优化油气田开发策略的静态储层建模是本研究的重点。进行静态油藏建模以估计波斯湾海上油田之一中上萨尔瓦克地层的油藏特性。白垩纪中期的 Sarvak 组被认为是伊朗南部和西南部最重要的生产油气藏之一。在本研究中，我们在地质统计学方法中使用了七个测井和 3D 地震数据进行储层建模。有效孔隙度和渗透率等岩石物理参数已使用连续高斯模拟方法进行估计。储集层岩石物理参数评价表明，平均有效孔隙度和渗透率为12。分别为 75% 和 51.5 mD。从储层特征的角度对岩石物理参数的评估表明，称为 A2 的区域具有最好的储层质量。采用交叉验证的方法实现了岩心数据的测井验证。w-01和w-03井渗透率和岩心数据的相关系数分别为86%和81%，表明序列高斯模拟是一种可以接受的方法。该研究结果可为该油田油气勘探研究和储层模拟模型的开发提供有用的信息。采用交叉验证的方法实现了岩心数据的测井验证。w-01和w-03井渗透率和岩心数据的相关系数分别为86%和81%，表明序列高斯模拟是一种可以接受的方法。该研究结果可为该油田油气勘探研究和储层模拟模型的开发提供有用的信息。采用交叉验证的方法实现了岩心数据的测井验证。w-01和w-03井渗透率和岩心数据的相关系数分别为86%和81%，表明序列高斯模拟是一种可接受的方法。该研究结果可为该油田油气勘探研究和储层模拟模型的开发提供有用的信息。
