摘要(Abstract):

分析碳酸盐岩油气储层的地震响应特征及井旁道频谱认为,碳酸盐岩储层对低频地震响应更敏感。通过低频阴影检测技术原理提取的古城地区油气储层低频、瞬时、强能量信息,凸显出碳酸盐岩油气储层的地震响应特征。实践证明,储层预测成果与实际钻遇情况完全相符,进一步验证了古城地区碳酸盐岩储层的成因规律。
The analyses of the characteristic of seismic reflection waves and frequency spectra along the well trajectory show that the carbonatite reservoirs response more sensitively to the low-frequency seismic survey.With the help of the low-frequency shadow detecting technique,the extracted low-frequency,instantaneous,strong-energy data of the petroleum reservoirs in Gucheng area highlight the seismic response characteristics of the carbonatite oil and gas reservoirs.The practice shows that the reservoir predicted results are consistent with those of the actual drilling and logging conditions,thus the genetic laws of the carbonatite reservoirs in this area are further certified.
