根据地质及地震资料分析区域构造演化,在系统的野外岩心观测及测井裂缝识别的基础上,通过古构造应力场数值模拟反演,恢复古构造应力场,从而进行储层裂缝预测,通过建立地质模型进行古构造应力计算,从裂缝的成因着手进行裂缝预测,将预测结果与实际资料进行对比,综合分析认为:这是一套行之有效的裂缝预测方法。
Based on the analysis of the regional tectonic evolution based on geological and seismic data, based on the systematic field core observation and logging identification, the paleocontinent stress field is retrieved through numerical inversion of paleocontinent stress field to predict reservoir fractures. By establishing According to the analysis of the paleo-structural stress in the geological model, the fracture prediction is started from the cause of the fracture. The prediction results are compared with the actual data. The comprehensive analysis shows that this is a set of effective fracture prediction methods.
