在单一裂缝预测技术不准确的基础上,提出了基于裂缝成因解析的储层裂缝综合预测方法。利用岩心、常规测井和成像测井等资料,进行储层裂缝的构造解析、确定裂缝成因类型,有针对性地采用相应的预测方法进行裂缝预测。通过对裂缝特征的分析,综合利用构造曲率、断层属性、相干体属性以及古构造应力场二维数值模拟对大邑构造须二段裂缝进行综合预测,然后对各种方法进行对比分析,最终确定裂缝的发育分布带。裂缝综合预测与实际应用结果具有较高的一致性,可为下一步勘探部署提供依据。
Based on the inaccuracy of a single fracture prediction technique, a comprehensive reservoir fracture prediction method based on the analysis of fracture causes is proposed. Using core, conventional logging and imaging logging data, the tectonic analysis of reservoir fractures is made to determine the types of fractures and the corresponding prediction methods are used to predict fractures. Based on the analysis of the fracture characteristics, the comprehensive prediction of cracks in the second member of Dayi area based on two-dimensional numerical simulation of tectonic curvature, fault attribute, coherence body property and paleotectonic stress field is carried out, and then the various methods are compared and finally determined Crack development zone. The comprehensive prediction of fractures is in good agreement with the actual application results, which can provide the basis for further exploration and deployment.
