川东北黄龙场气田飞仙关组台缘滩型碳酸盐岩储层预测
|
摘要
在沉积与储层基本特征研究的基础上,利用多种地震预测方法对川东北黄龙场气田下三叠统飞仙关组鲕滩储层的分布进行了预测:利用地震剖面层拉平方法,恢复了黄龙场气田飞仙关期东高西低的沉积古地貌,自东向西依次发育台地边缘、台缘斜坡及陆棚相带;根据地震响应特征,识别出4种不同的地震相类型,并且利用神经网络波形聚类技术,指出了不同地震相的平面分布;通过均方根振幅、波形及弧长等地震属性的提取与处理,发现飞仙关组鲕滩储层具有强振幅、高频衰减、强相位异常等特征,揭示了鲕滩储层主要分布于东部的D4井—hl6井—hl9井一带;应用井约束稀疏脉冲反演方法,指出飞仙关组鲕滩储层低速异常明显,主要分布在距飞四底反射层0~60ms范围内;利用三维地震数据体追踪点集,雕刻了飞仙关组鲕粒滩体的三维空间分布特征。实际应用效果表明,该地震储层预测技术方法体系对四川盆地东北部鲕滩储层的预测具有较好的指导意义。
The characteristics of deposition in the carbonate reservoirs of Feixianguan Formation in the Lower Triassic of Huanglongchang Gas Field in the northeastern Sichuan Basin were studied by the use of geologic-seismic integrated method.The seismic profile was flattened to the base of Member 4 in Feixianguan Formation to restore the depositional paleogeomorphology during the Feixianguan period.The result indicated that the eastern area was higher than the western area in the depositional paleogeomorphology,and the platform-edge,slope and continental shelf were developed from east to west.According to the seismic response characteristics,four types of seismic facies were recognized.The distribution of seismic facies was divided using the neural network waveform clustering technique.The research of seismic attribute shows that the oolitic bank reservoir in Feixiangan Formation has the characteristics of high amplitude,high frequency attenuation and abnormal phases,and the oolitic bank reservoirs mainly distributed in the eastern area of D4-h16-h19 wells.The application of the constrained sparse spike inversion method found that the oolitic bank reservoirs of Feixianguan Formation had apparently abnormal low P-wave impedance and were developed in the range of 0~60 ms above the base of Member 4 of Feixianguan Formation.The 3-D space distribution of oolitic bank in Feixianguan formation was described by using the 3-D seismic data.The field application of the reservoir seismic prediction system has achieved good effects in the prediction of the oolitic bank reservoirs in the northeastern Sichuan Basin.
