准噶尔盆地中部表层地震地质条件复杂。油气藏类型主要为低幅度构造控制下的岩性油气藏.用常规地震勘探资料圈定此类油气藏不能得到很好的地质效果.而提高分辨率地震资料及相关的解释技术可以解决这个问题。首先,利用模型正演对研究区地震资料的分辨率进行了探讨;然后.利用提高分辨率地震资料进行了精细层位标定和精细构造解释;最后,综合应用地震属性分析、谱分解、测井约束反演等技术进行了岩性圈闭的识别与描述。研究结果得到了钻井的证实。

The main type of reservoir is lothologic reservoir controlled by lowness amplitude structures in Junggar basin, and complex seismic geologic condition. Improved the seismic data resolution integrated interpretation technology seek lothologic hydrocarbon reservoir for well geology effort. Research the seismic data resolution using to model forward, then demarcation fine horizon and fine structure elucidation, finally, identify lothology trap from composite application in seismic attribute analysis, spectral factorization and log constrained inversion technologies. Result was veritied by posterior wells.
