【摘要】 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。以川西坳陷大邑构造、新场构造须二段为例,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。更多还原

【Abstract】 According to the area structural evolution from geologic and seismic data analysis,the numerical simulation conversion outcome for palaeotectonic stress field is presented,further it is restored,thus the formation fracture prediction can be obtained,on basis of the systematic core observation and fracture discrimination by well logging.In terms of origin,the fracture prediction has been undertaken by means of establishing geological model for palaeotectonic stress calculation,taking the Dayi structure in Chuanxi sag and the Xinchang tectonics Xuer section for example.The comprehensive analysis indicates that this method is quite effective after the forecast results are compared with the actual data.更多还原
