近年来,地震属性广泛应用于油气勘探开发中,在地震解释构造等领域发挥着越来越重要的作用。地震属性分析技术在解释地震构造、分析地层、了解油藏特征和准确分析油藏储量中发挥的作用日益显着。以川西北九龙山气田须二上亚段为例,通过地震属性分析,确定均方根振幅、弧长和平均反射强度在该区对含气异常较敏感。
In recent years, seismic attributes are widely used in oil and gas exploration and development and play an increasingly important role in the field of seismic interpretation and other fields. Seismic attribute analysis techniques play an increasingly significant role in explaining seismic structures, analyzing formations, understanding reservoir characteristics and accurately analyzing reservoir reserves. Taking the Upper Second Member of the Second Silurian in Jiulongshan Gas Field, northwestern Sichuan as an example, it is determined that the root mean square amplitude, the arc length and the average reflection intensity are sensitive to the gas anomalies in this area through seismic attribute analysis.
