Description
For rational design of drilling process parameters and guarantee of safe drilling, law of carrying cuttings in horizontal well drilling of marine natural gas hydrate should be intense research to effectively reduce the friction of drilling tools and avoid well blockage. The research was carried out through FLUENT simulation, orthogonal test analysis, rock carrying experiment verification. The critical velocity charts of different hydrate abundance, hydrate-cuttings particle size and drilling fluid density were obtained. Simulation results show that: The critical rock-carrying velocity increases with the increase of the grain size of hydrate-cuttings, decreases with the increase of drilling fluid density, and decreases with the increase of hydrate abundance. Orthogonal test method was used to evaluate the influence of various factors on rock carrying capacity: hydrate-cuttings particle size hole enlargement way hydrate abundance drilling fluid density. The influence of different ways of diameter enlargement on the law of rock carrying is greatly considered in the paper. The research results provide an early technical support for the construction parameter optimization and well control safety of horizontal well exploitation models in marine natural gas hydrate reservoir. 2020, Springer Nature Singapore Pte Ltd.
