针对深海钻探过程中测井参数(声波时差)获取代价大、且传统数据驱动的声波时差软测量方法在跨井应用中泛化能力不足等问题,提出一种基于双域自适应混合专家模型的深海钻探过程声波时差软测量方法. 该方法融合多源钻探数据,根据低频可迁移的趋势域与高频相关的残差域,分别构建声波时差多专家软测量模型;在此基础上,引入自适应混合权重,通过多源无监督信号动态评估两域的可信度,实现声波时差的自适应融合. 在多口实际钻井数据上的对比实验表明,所提方法在跨井预测精度与稳定性方面均优于SVR、RF、RNN、LSTM及Transformer等对比模型,平均误差降低约15%. 该方法在仅依靠钻前勘探与钻井数据的前提下,有效平衡了预测精度与跨井应用的稳定性,适用于深海钻探环境下的声波时差实时软测量.
In deepwater drilling operations, the acquisition of logging parameters such as sonic transit time (DTCO) is associated with high cost and operational constraints, while conventional data⁃driven soft⁃sensing methods often exhibit limited generalization capability in cross⁃well applications. To address these challenges, this study proposes adual⁃domain adaptive mixture⁃of⁃experts⁃based soft measurement method for sonic transit time in deep⁃sea drilling processes.This method integrates multi⁃source drilling data and constructs separate multi⁃expert soft measurement models for acoustic travel time based on low⁃frequency migratory trend domains and high⁃frequency residual domains. Building on this, adaptive mixed weights are introduced to dynamically assess the reliability of the two domains using multi⁃source unsupervised signals, thereby achieving adaptive fusion of acoustic travel times.Comparative experiments conducted on multiple real drilling datasets demonstrate that the proposed method consistently outperforms benchmark models, including SVR, RF, RNN, LSTM, and Transformer, in terms of cross⁃well prediction accuracy and stability, achieving an average error reduction of approximately 15%.This method effectively balances prediction accuracy with the stability of cross⁃well application whilst relying solely on pre⁃drilling exploration and drilling data, and is suitable for real⁃time sonic transit time soft measurement in deep⁃sea drilling environments.
