摘要
裂缝性储层非均质性强、成藏条件复杂。为提高该类储层的预测精度,引入了利用地震能量吸收分析技术预测储层的方法,并开发了相应软件。结合地质、钻井资料,将该技术应用于车古201潜山碳酸盐岩和罗42井区泥岩裂缝油藏的储层预测中,得到的吸收系数数据较好地反映了潜山和泥岩裂缝储层的裂缝发育程度及含油气信息。表明该技术在裂缝性储层的评价中具有较好的应用价值。
Fracture reservoir with much heterogeneity was formed under complex geological conditions. To improve theprediction accuracy of this kind of reservoir, a method based on seismic energy absorption analysis was introducedfor reservoir prediction. Using software developed on the study and combining geology and wellbore data this tech-nique was used to make prediction in the carbonate reservoir at Chegu 201 buried hill and mudstone fracture reservoirat Luo 42 . The obtained absorption coefficient could demonstrate preferably the fracture development degree and oiland gas bearing information of the respective reservoir. It proves that the technique can be used effectively in the eval-uation of fracture reservoir.
