罗利,任兴国,姚声贤.花岗岩储层裂缝评价及其横向预测,测井技术,1998,22(3):204~207分析了研究区块花岗岩的岩电特征。用密度、中子资料确定其岩石成分;用常规资料准确识别裂缝,识别结果与井周声波成像处理结果吻合;用地层倾角描述裂缝类型和产状;用有限元素法反演研究区块的应力场,将得到的应力场参数与测井处理的裂缝发育度结合,设计神经网络进行网络训练,得到将应力场转换为裂缝发育度的模型;使用模型参数,得出每一单元的裂缝发育度,根据裂缝发育度的大小分布预测出研究区块的裂缝发育带。这种裂缝发育带横向预测技术更合理,预测结果更可信。
Raleigh, Ren Xingguo, Yao sound Yin. Evaluation of Granite Reservoir Fractures and Its Lateral Prediction, Logging Techniques, 1998,22 (3): 204 ~ 207 The rock electrical characteristics of the granitic rocks in the study area are analyzed. The rock composition was determined by density and neutron data. The fractures were accurately identified by conventional data. The recognition results were in good agreement with the well-sonic imaging results. The dip types were used to describe the fracture types and occurrences. The finite element method Field, the obtained stress field parameters and logging treatment of fracture development combined with the design of neural network for network training, the stress field is converted to the degree of fracture development model; using the model parameters, the fracture development of each unit According to the size distribution of fracture development, the zone of fracture development in the study area is predicted. This fracture development with lateral prediction technology is more reasonable, the forecast result is more credible.
