Abstract

The invention discloses a soil layer deformation testing device in a natural gas hydrate horizontal well layered mining process, which can simulate the natural gas hydrate horizontal well layered mining process, and adopts a mode of cooperative acquisition of a high-density resistivity tomography method, a micro-seismic monitoring method, an optical fiber sensing testing method and a mechanical measurement method, soil layer deformation and stress data in the hydrate exploitation process are comprehensively measured and analyzed; meanwhile, the soil layer deformation obvious area is determined through numerical simulation, preliminary experiment development and other methods, various sensors and probes are reasonably pre-buried in the soil layer, and the experiment effects that the sensors are reasonably arranged, mutual interference is small, and the measurement data precision is high are achieved.

Description

technical field [0001] The invention relates to the field of hydrate exploitation, in particular to a soil layer deformation testing device in the layered exploitation process of a natural gas hydrate horizontal well. Background technique [0002] my country's South China Sea is rich in natural gas hydrate resources, and its reserves are as high as 100 billion tons of oil equivalent. It is of great significance to realize its large-scale and low-cost development as soon as possible to meet my country's demand for clean energy. The natural gas hydrate deposits in the pores of the soil layer, which plays a role in cementing sediment particles, filling pores, and increasing sediment density. During the stratified exploitation of natural gas hydrate by horizontal wells, due to the double deficit effect of reservoir energy and material, the overlying soil layer may produce collapse zones, fracture zones, and curved subsidence zones, especially when the overlying soil layer is thi...
