波阻抗反演在YD地区储层预测的应用

Application of the Wave Impedance Inversion in Reservoir Prediction in YD Area

在溱潼凹陷开展波阻抗反演技术应用研究,对推动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YD地区储层发育特点,重点解决了YD地区阜三段测井资料标准化、反演标定及子波提取、地质框架结构的建立、λ参数优选等关键问题。实际应用表明,预测效果与已知钻井资料相吻合,取得了较好的效果,达到了提高隐蔽圈闭识别精度,促进隐蔽油藏勘探的目的。

It is significant to carry out the research about the wave impedance inverse technology in the aspect of developing the exploration in the elusive reservoirs.Basic procedure of the sparse-spike inversion constrained by Jason Inversion Technique as aplatform is combined with the features of reservoir development in YD Region.The measures can solve many key problems such as log data normalization,wavelet extraction,geologic modeling andλparameter.The result shows that the predicted effect is consistent with drilling data and it also can achieve the aim of improving the recognizing accuracy of the subtle trap and of promoting the exploration in the subtle reservoirs.
