LABORATORY SIMULATION OF NATURAL GAS HYDRATE FORMATION AND LOW DISTURBANCE DRILLING
ABSTRACT
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.
