Abstract: An in-situ stress measurement device for ultra-deep non-vertical drilling adopts a technical route of single channel and bidirectional rolling of in-hole equipment, and its related functions are mainly realized by a bidirectional rolling device and a split-type axial-force-free circuit switching valve. The bidirectional rolling device can drive the in-hole equipment to move freely in a circumferential direction and back and forth, which changes sliding friction between the in-hole equipment and a hole wall into rolling friction during an in-situ stress measurement of non-vertical drilling. The split-type axial-force-free circuit switching valve provides a technical solution for a single-pipe test in the non-vertical drilling.
