摘　　要：针对常规纵波资料在裂缝检测、流体识别和岩性判别等方面存在的局限性,多分量地震勘探技术逐渐兴起。而作为一项发展中的新技术,多分量地震资料的处理、解释方法尚不完善,尤其是多分量地震资料的储层预测技术,系统研究的还很少。通过钻、测井资料与地质资料的结合完成多分量地震资料层位对比、追踪,在此基础上开展裂缝预测、孔隙度预测、密度反演及纵横波联合反演、属性提取与分析等工作,然后综合上述成果完成岩性识别和含流体检测等储层预测工作。该方法在GA地区二维三分量资料的储层预测中能准确预测孔隙度值、正确识别和判别出裂缝分布、岩性及含流体性,为多分量地震资料的储层预测提供了一套可参考的解释流程。Because of the limitations of conventional P-wave seismic in fracture detection,fluid identification,and lithologic determination,multicomponent seismic is coming to be accepted again.As a developing technology,multicomponent seismic needs to be refined in data processing and interpretation,especially in reservoir prediction.In this paper,drilling,logging,and geological data were combined to fulfill the horizon correlation and tracking on multicomponent seismic data.Based on the results,fracture prediction,porosity prediction,density inversion,P-wave and PS-wave joint inversion,as well as attribute analysis were carried out.Identification of lithology and detection of fluid were also implemented.Desired results have been reached in determination of fracture distribution and identification of lithology and hydrocarbon potentials in GA 2-D 3-component block.A workflow of reservoir prediction has been established for multicomponent seismic data.
