平湖油气田花港组油藏储层三维模型建立

基于单井和地震资料，对花港组储层空间展布、砂体叠置关系进行分析；咀克里格插值技术为手段，通过研究储层顶、底界面及断层的空间展布建立构造模型，利用基于目标的示性点过程算法，建立花港组油藏沉积微相模型，在此基础上应用相控随机建模技术，采用高斯模拟进行储层物性模拟，建立了花港组储层三维随机模型。在建模过程中，运用井资料和地震波阻抗信息相结合的联合建模技术，提高三维模型的精度，为提高后期油井措施调整的预测精度奠定了基础。

3D geological modeling of Huagang Formation oil reservoir in Pinghu oil and gas field

Based on single -well and seismic data,spatial distribution of reservoirs and superimposed relationship among sand bodies of Huagang Formation are analyzed. Using Kriging interpolation, the author established a structural model after research on top/ bottom interface of reservoirs and spatial distribution of faults. Using process arithmetic of general marked point based on the target,the author constructed sedimentary microfacies model of Huagang Formation oil reservoir. Then 3D probabilistic model of Huagang reservoirs was made after physical properties of reservoirs had been simulated using facies - controlled probabilistic modeling technique and Gauss simulation. During model construction,modeling technology combined well data with seismic wave impedance were used to improve the precision of the 3D model mentioned above,and it laid a foundation for the prediction precision of oil well measure adjustment at the later stage of development.
