针对松辽盆地北部砂泥岩薄互层的地质特点 ,结合三维地震和高分辨率地震的优势 ,开展了高分辨率三维地震的研究工作。采集上在确保资料信噪比的前提下拓宽有效频带 ;处理上实现了在高信噪比基础上的高分辨率处理 ,使得地震资料在纵向和三度空间上能够更准确可靠地反映地下地质情况。地震解释采用先进的全三维构造精细解释和多信息多方法的综合地震岩性解释技术 ,提高了小断层、小幅度构造和储层预测的精度 ,经开发井验证 ,取得了较好的地质效果和经济效益。
According to the geological characteristics of sandstone and mudstone thin interbedded layers in northern Songliao Basin, the research on high resolution 3D seismic data is carried out based on the advantages of 3D seismic and high resolution seismic. Acquisition to broaden the effective frequency band under the premise of ensuring signal-to-noise ratio of data; processing to achieve high-resolution processing based on high signal to noise ratio, making the seismic data more accurately and reliably reflect the underground geology in the vertical and the three dimensional space Happening. The seismic interpretation uses the advanced full three-dimensional tectonic interpretation and multi-information and multi-method integrated seismic lithology interpretation techniques to improve the accuracy of small faults, small amplitude structures and reservoir prediction. The developed wells have been verified and achieved good geological effects And economic benefits.
