摘要
文中选择W工区为研究目标区,对页岩气地质甜点的关键参数敏感参数选择进行研究。研究中从页岩气地质甜点关键参数的测井和地震表征方式入手,确定了利用最小二乘法进行参数统计分析确定敏感参数以及排序,选择敏感度较高的参数通过多元统计分析拟合页岩气地质甜点关键参数与敏感参数之间的的关系式,选择叠前叠后地震反演方法预测页岩气地质甜点关键参数的研究思路与方法,在实际应用中效果较好,具有针对性和可推广性。
In this paper,w work area is selected as the research target area to study the sensitive parameters selection of key parameters for shale gas geological desserts. Starting from the logging and seismic characterization of the key parameters of shale gas geological desserts,research ideas and methods are determined,is that choosing the least square method to carry out parameter statistical analysis and determine the sensitive parameters and order,the parameters with high sensitivity are selected to fit the relationship between the key parameters and sensitive parameters of shale gas geological desserts through multivariate statistical analysis,and the pre stack and post stack seismic inversion method is selected to predict the key parameters. The research ideas and methods are effective in practical application,and have pertinence and popularization.
