约束稀疏脉冲反演在储层预测中的应用
|
摘要
海通集洼陷北部属于复杂断块区,地质建模比较困难,依赖于初始模型的常规反演方法难以获得精确的反演结果。而约束稀疏脉冲反演不依赖模型,其反演的精度取决于原始数据特征。为此,在海通集洼陷北部利用约束稀疏脉冲反演技术进行了储层预测。首先简单介绍了约束稀疏脉冲反演技术的基本原理及其实现方法,着重讨论了通过比较合成地震记录和原始道的吻合程度确定有关参数的原则;然后对砂体的发育情况进行了预测,其反演结果与井的钻探结果基本吻合。
Constrained sparse pulse inversion is one of geological inversion methods based on the wave impedance of the reservoir, so the reservoir prediction could be done in spite of the insufficient data by making iteration between seismic reflectance sequences and raw drilling and logging data. Firstly, the principle and realization of the constrained sparse pulse inversion is introduced, then determining principle of parameters is discussed by comparing synthetic seismogram and original data, finally, the development of sandstone was predicted by using this inversion method, the results verified the precision of the reservoir prediction.
