AB - Obtaining real natural gas hydrate pressure-retaining samples is challenging,  necessitating the study of in-situ condition preserved coring (ICP-Coring)  technology. In this paper, we simulated the in-situ formation of natural gas  hydrate natural gas hydrate using a high pressure cooling method within a  self-developed formation environment simulation chamber. Drilling  experiments were conducted to examine the influence of drilling parameters  on low disturbance drilling processes. Our findings indicate that the feed  rate of the drill pipe primarily affects the force magnitude on the drill  pipe, while the rotational speed of the drill pipe significantly impacts the  stability of this force, with slightly higher rotational speeds resulting  in less disturbance.
