地震反演技术在齐家北地区储层预测中的应用

Application of seismic inversion technique in reservoir prediction in Qijiabei area

针对齐家北地区砂体薄、纵向难识别的特点,选用了一种能适合该区储层识别的拟声波反演技术。实践表明,拟声波曲线能很好地反映出该区探井地层岩性的变化,曲线上砂泥岩岩性特征十分清楚。以松辽盆地北部齐家北地区扶余、高台子油层为例,介绍拟声波在储层预测中应用效果和利用地震反演预测储层的思路。该反演技术不但能较为准确的预测储层,而且为生产提供可靠的依据。

Seismic inversion technique plays an important role in reservoir prediction.In recent years,the seismic inversion technique is applied more extensively in petroleum explora- tion and development,and becomes a reliable reference for submitting reservoir and well sites.Taking Fuyu and Gaotai- zi oil horizons in the north of Qijia area in north Songliao ba- sin as an example,the application effect of quasi-acoustic wave in reservoir prediction and the approach of applying seismic inversion in reservoir prediction are introduced.The seismic inversion technique can predict reservoirs more accu- rately,and can present more reliable basis for petroleum production as well.
