Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with the accompanying drawings, but the implementation scope of the present invention is not limited.
[0016] (1) According to the geological data of natural gas hydrate reservoirs, the natural gas hydrate reservoirs with an average effective thickness of 40m are selected, two horizontal wells are drilled, the upper and lower wells are drilled, the length of the horizontal well section is 500m, and the insulating casing 5 is used to complete the well; in order to improve The development effect improves the development efficiency. Both the upper and lower horizontal wells are connected to the natural gas hydrate reservoir through casing perforation 8; The oil pipe 10 is connected to the gas-liquid separator 4, and the water and gas produced by the decomposition of natural gas hydrate are separated and processed through the gas-liquid separator 4;
[0017] (2) Install the ground control cabinet 1. The...
