摘要
海拉尔—塔木察格盆地南贝尔凹陷北洼槽构造复杂,储层为砂泥岩薄互层,普遍含有凝灰质,且横向变化快,因此储层物性较差。针对这种复杂的构造和储层特征,本文在精细的层位划分和构造解释基础上,依据子波分解重构后的波形分量和频谱特征进行储层预测和含油气检测,取得了明显效果。
Structures in the north of south-Bel depression are very complicated.Sand and shale are interbedded with contained tuffaceous sandstone and variant facies.Based on the reservoir characteristics,we first delineate sequence stratigraphy and interpret horizons,and then we predict reservoir and detect hydrocarbon based on components of wave pattern and spectrum attributes after multi-wavelet decomposition.Our study results have been proved.
