Research on the Quantitative Characterization of Geological Engineering Parameters Based on the Principal Component Analysis Method

本文针对地质工程中压裂井的复杂性，提出了一种基于主成分分析法(PCA)的地质工程参数定量表征方法。通过对地质工程参数的相关性分析，筛选出与无阻流量具有较强相关性的参数，并利用主成分分析法对其进行定量分析，实现了对压裂井压前和压后产能的详细评估。该方法能够有效降低数据维度，保留关键信息，并为地质工程一体化压后评估体系提供科学依据。
Aiming at the complexity of fractured wells in geological engineering, this paper proposes a quantitative characterization method of geological engineering parameters based on the Principal Component Analysis (PCA). Through the correlation analysis of geological engineering parameters, the parameters with a strong correlation with the open flow capacity are screened out, and the PCA is used for their quantitative analysis, realizing a detailed evaluation of the pre-fracturing and post-fracturing productivity of the fractured wells. This method can effectively reduce the data dimension, retain key information, and provide a scientific basis for the integrated post-fracturing evaluation system of geological engineering.
