松辽盆地南部新立油田泉三、四段薄互层储层预测研究
|
摘要
根据松辽盆地南部新立油田泉头组的地质特征,在三维地震资料叠后处理提高剖面品质的基础上,有针对性地运用小波分频处理、测井曲线重构技术、非线性高精度薄砂体预测技术,对泉三、四段薄互层河道砂岩储层展开了地震反演预测工作.结果表明,厚度在3m以上的薄储层均能识别,钻井符合率达74.8%.
Based on the high-quality 3-D post-stack seismic data,we use wavelet frequency-division process,sonic log reconstruction and non-linear constrained inversion techniques to do a reservoir prediction on the thin-bed channel sands of the Quantou formation in the Xinli oilfield,southern Songliao basin.The results show that most of the layers whose thicknesses exceed 3 meters can be recognized and 74% of them are proved to be valid by the new-drilled wells.
