Three-dimensional simulating device for the stratum stability in the natural hydrate exploitation
A three-dimensional simulating device for the stratum stability in natural gas hydrate exploitation includes a three-dimensional model located in an environmental control unit, an axial pressure control unit, and a post-processing unit. An inner cavity of the three-dimensional model is divided into a sealed simulating cavity and a sealed axial pressure sealing cavity by an axial pressure sealing piston arranged in the inner cavity. A vertical well and a horizontal well stretch into the simulating cavity. The axial pressure control unit, the environmental control unit, and a plurality of sensors in the three-dimensional model are electrically connected to the post-processing unit. This simulating device simulates the external environment and combines in-situ synthesis and decomposition of a hydrate with stratum stability, thereby achieving high reliability and high accuracy, comprehensively evaluating mechanical characteristic change of the stratum and the stratum stability to provide guidance in natural gas hydrate exploitation.
