Jason反演技术在李堡地区储层预测中的应用

在海安凹陷开展Jason反演技术应用研究,对推动本区隐蔽油藏勘探技术具有重要意义。以Jason软件约束稀疏脉冲反演的基本流程为平台,结合李堡地区储层发育特点,重点解决了测井资料归一化、子波提取、地质建模、Lambda取值等关键问题,实现预测效果与钻井资料、区域沉积特征相吻合,达到提高隐蔽圈闭识别精度,有效促进隐蔽油藏勘探的目的。

THE APPLICATION OF THE Jason INVERSION TECHNIQUE TO RESERVOIR PREDICTION IN LIBAO AREA

It is of great significance to apply Jason Inversion Technique to Haian sag for subtle reservoir exploration.In this paper,taking basic flow of Jason software constrained sparse pulse inversion as the platform,in combination with the reservoir distribution of Libao area,the authors successfully solved such key problems as logging information normalization,wavelet extraction,geological modeling and Lambda data selection.It is proved that the forecasting results coincide with drilling data and regional sedimentary features.Therefore,Jason inversion technique can enhance the precision of subtle trap recognition and boost the subtle reservoir exploration process in this area.
