摘要
叠前地震裂缝检测技术是目前裂缝型储层定量描述的主要手段之一,利用地质、测井资料和岩石物理参数,根据岩石物理理论建立裂缝储层的理论地质模型,模拟地震波在已知裂缝模型中传播时各个方位的地震响应,分析某区段由裂缝引起的地震振幅属性的方位AVO(AVAZ)特征,利用该技术流程,编写了一套基于HTI介质的正演模拟软件,在软件开发过程中,研发了基于Qt Concurrent编程模型组件的并行处理技术.通过该项技术的研究与开发可以:1)利用地震属性数据实时分析地下裂缝型储层的地震响应规律;2)解决地震振幅数据方位各向异性特征的不确定性导致的各向异性椭圆解释成果错误问题,确定椭圆的正确方位指示;3)为叠前裂缝检测软件提供正演分析工具,完善并扩充检测流程.在实际生产应用的效果表明,正演的解释结论能够为叠前裂缝检测提供有效的理论依据,增强了反演裂缝方位数据的准确性与可信度.

Research and development of the technology can be: 1) using seismic attribute data analysis of underground reservoir seismic response law; 2) to solve the elliptic anisotropic seismic amplitude data leads to azimuthal anisotropy of the uncertainty of the interpretation errors,determine the correct orientation of elliptical instructions; 3) to provide forward analysis the tool for pre stack fracture detection software,improve and expand the detection process. In the practical application,the results show that the forward modeling results can provide effective theoretical basis for pre stack crack detection,and enhance the accuracy and reliability of the inversion fracture azimuth data.
