超深高压定向钻孔内热-水-力多场耦合参数原位测试装置及方法
By designing an in-situ testing device for multi-field coupled parameters of thermal-hydraulic-mechanical systems in ultra-deep high-pressure directional boreholes, and employing a hydraulically driven packer and a deep learning model, the device achieves synchronous acquisition and coupling correction of multiple parameters. This solves the problems of sealing failure and data interpretation lag in traditional testing, improves testing efficiency and data accuracy, and enables real-time early warning of surrounding rock risks.

Abstract
本发明涉及岩土工程与深地探测技术领域，其公开了一种超深高压定向钻孔内热‑水‑力多场耦合参数原位测试装置及方法，解决传统测试中钻杆轴向传力致坐封失效、多参数测试效率低、数据解释忽略多场耦合、无法实时量化围岩风险的问题。本发明中的测试装置包括多芯铠装线缆、井下测试装置和地面控制计算系统，其中，井下测试装置为中心管式一体化结构，沿中心管依次集成电控通讯模块、上下封隔器及多功能测试模块。在应用时，下放井下装置至目标层位，通过液压驱动控制封隔器坐封形成密封隔离段，然后向密封隔离段注水致裂并同步采集多源数据，压裂后采集裂缝数据，经数据反演与耦合修正，计算孔壁塑性区并量化风险，最后回收装置。
