利用改进组合交叉熵实现煤层气储层地震属性约简
Seismic attribute reduction of CBM reservoir using improved combined cross entropy
摘要
Abstract
In the prediction of CBM reservoir parameters, the redundancy of seismic attribute data brings incon-venience to the prediction.In order to obtain the optimal reduction of seismic attributes of CBM reservoir, an method using improved cross entropy algorithm to optimize seismic attributes was proposed. This method im-proved the samples generated by the iterative process, and then generated an excellent set of samples. At the same time, the model of rough set attribute reduction was used as the objective function to solve the optimization. The model of attribute reduction of rough set is solved by using the improved combined cross entropy algorithm. Finally, the seismic attributes in an area were used to verify and compare the algorithm with the other algorithms. The re-sults show that the algorithm is less time-consuming, has high precision and ratio of reduction, and can be effec-tively used in seismic attribute reduction of CBM reservoir.关键词
