摘要:
贝西次凹历经多期构造运动改造,具有多物源、短物源、相变快的典型断陷型盆地特点。地震属性分析技术是储层预测的有效手段之一,但是单一的地震属性多解性强,因而常用多属性融合技术预测储层分布。然而传统的属性融合技术只是不同地震属性的加权数学运算,其没有考虑到不同沉积环境的影响,因而其效果在断陷型盆地储层预测中也不甚理想。由于不同的沉积环境通常在地震波形特征上有所差异,在传统的属性融合技术基础上进一步根据地震波形的不同将研究区划分不同区域,再针对不同区域分别开展优势地震属性融合预测储层展布,最终综合为全区的储层预测结果。其结果与井钻遇情况及沉积规律吻合度较高,证明该技术可以提高断陷盆地储层预测精度。
Abstract:
The Beixi Subsag which has been modified by multiple phases of tectonic movements has the typical characteristics of faulted basins with multiple sources,short sources,and rapid facies changes. The seismic attribute analysis technique is one of the effective methods for reservoir prediction,but a single seismic attribute is highly multi-solvable,so the multi-attribute fusion technique is commonly used to predict reservoir distribution. However,the traditional attribute fusion technique is only a weighted mathematical calculation of different seismic attributes,which does not take into account the influence of different depositional environments and is therefore not very effective in reservoir prediction of faulted basins. Since different depositional environments usually differ in seismic waveform characteristics,the traditional attribute fusion technique is further used to divide the study area into different areas based on the different seismic waveforms,and then carry out the dominant seismic attribute fusion to predict the reservoir spreading for each area,which is finally integrated into the reservoir prediction results for the whole area. The results are in good agreement with the well drilling encounter and deposition pattern,proving that the technique can improve the reservoir prediction accuracy in faulted basins.
