应用开发地震技术进行徐家围子储层构造和岩性反演

应用LandM ark工作站对徐家围子葡萄花油层进行了精细构造解释,恢复了徐家围子古构造格局。在建立波阻抗反演地质模型的基础上,获得高分辨率地震地层波阻抗资料,对葡萄花油层薄砂层油藏进行了精细描述。综合应用开发地震地质分析方法,从构造、断层发育情况、岩性预测结果和油藏剖面图等地质解释结果相结合,是一套切实可行的预测有利含油区的方法。

APPLICATION OF DEVELOPMENT SEISMIC TECHNIQUE TO THE STRUCTURAL AND ROCK CHARACTER INVERSION OF PUTAOHUA RESERVOIR IN XUJIAWEIZI SYNCLINE,DAQING OIL-FIELD

The elaborate structural characteristics of Putaohua reservoir in Xujiaweizi syncline,Daqing Oil-Field,have been interpreted using the LandMark station,and the paleo-tectonic framework has been re-constructed as well.On the basis of constructing the geological inversion model of wave impedance,the wave impedance data of high-resolution seismic strata has been acquired,and the thin sandstone layer of Putaohua reservoir has detailedly been described.The comprehensive analysis of development seismic technique and geology,combining with tectonics,fault development,rock character prediction and reservoir profile,is an effective technique for the prediction of favorable oil-bearing zone.
