地震反演技术在齐家北地区储层预测中的应用

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。

Application of seismic inversion technique in reservoir prediction in Qijiabei area

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.
