大邑构造须二段储层裂缝综合预测
|
摘要
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。
Fractures prediction is not accurate with single technology,so that comprehensive prediction of reservoir fractures based on genesis analysis is proposed.Coring,logging and image logging data are employed to conduct structural analysis of reservoir fractures,to determine fracture genesis,and to predict fractures with adequate methods.Based on analysis of fracture characteristics,the comprehensive method has predicted fractures in the Xu2 formation of the Dayi structure using structure curvature,fault attributes,coherence cube attributes,and 2D numerical simulation of paleo-tectonic stress field.After comparative analysis of different methods,the distribution of fractures is finally defined.The fractures predicted by comprehensive method are highly consistent with practical result,therefore can provide reference for future exploration deployment.
