Title: Sheng Luo and In-Situ Stress Measurement for Ultra-Deep Non-Vertical Drilling.
Introduction
Sheng Luo is an inventor based in Wuhan, China. His work includes a patented device and method for measuring in-situ stress in ultra-deep non-vertical drilling.
Latest Patents
Luo’s patent, “In-situ stress measurement device and method for ultra-deep non-vertical drilling,” describes a single-channel system that uses bidirectional rolling for downhole equipment. A bidirectional rolling device allows the equipment to move circumferentially and back and forth, replacing sliding friction against the borehole wall with rolling friction during measurement. A split-type, axial-force-free circuit switching valve supports single-pipe testing in non-vertical drilling.
The design reduces wear on both the downhole equipment and borehole wall during installation and withdrawal, while helping protect the markings used for impression measurement. It is intended to support efficient hydraulic-fracturing-based in-situ stress measurement in ultra-deep, non-vertical wells. Luo is associated with 1 patent.
Career Highlights
Luo works with Changjiang River Scientific Research Institute. His patent focuses on addressing practical challenges in downhole equipment movement and measurement in ultra-deep, non-vertical drilling.
Collaborations
Luo’s listed coworkers include Zhihong Dong and Xinhui Zhang.
Conclusion
Sheng Luo’s patented system combines bidirectional rolling and a specialized switching valve to reduce wear and support in-situ stress measurement in ultra-deep non-vertical drilling.
