密井网条件下砂岩储层自动对比方法研究

针对储层自动对比以往基于单纯数学模型而缺乏专家经验难以在复杂的实际应用中得到推广的难题,本文根据密井网条件下油田测试资料全、对比要求精度高的特点,提出了人工智能与信号处理相结合自动对比方法,依据＂分级控制、旋回对比、不同相带,区别对待＂的对比原则,研制了一套密井网条件下河流-三角洲相储层自动对比方法,即根据研究区标准层的地质和曲线特征,采用改进的F.Kemp方法首先识别出标准层,然后在标准层控制下,通过候选点寻优,一致性检验进行断层自动解释,最终根据沉积旋回原理细分出各个小层。

The Study of Auto Contrast Method on Sandstone Reservoir in Density Well Net

Because of the complexity and particularity,especially the result is more depend on the expert＇s experience.the calculate method which is based on the simplicity mathematical model and short of he expert＇s experience is hardly to have any effective in the practice which is more complexity.The coalescent method of artificial intelligence and signal manage in the correlation of reservoir use log curve has been put forward in this paper.Following the principle of ＂controlled by classification and correlation ＂.The system of correlation has been setup,which can identify ＂standard layer＂ first,and then on the basis of ＂standard layer＂,interpret the fault,last identify the layer.Through the application,this system has high precision and will become a useful tool in the study of geology.
