摘要
在碳酸盐岩储层中,裂缝能够起到改善储层流通性的作用,如何利用地震数据确定高角度构造裂缝的分布特征,仍是各大油田密切关注的问题。通过对弯曲薄板理论的分析,以构造图和速度为基础,进行现今应力场的数值模拟,从而预测构造裂缝的发育程度和方向。将该方法应用于实际资料中,并以研究区内的成像测井资料为验证,预测的构造裂缝发育情况在单井裂缝方向以及裂缝平面规律上,均具有令人满意的效果。
In carbonate reservoirs,the fracture could improve the liquidity of the reservoirs,but how to predict the distribution of the high-angle structural fractures with seismic data was still a problem related to the researchers of the major oilfields.Based on the analysis of curved plate theory,based on the structural diagram and velocity data,a numerical simulation on current stress field was carried out to predict the development extend and direction of structural fractures.The method is applied to the actual data analysis,and FMI logging data of the studied area is used for validation.The predicted development characteristics of structural fractures have a satisfactory effect on both single well and plane.
