Hydrothermal geothermal development method of multilateral well closed circulation

The present disclosure provides a hydrothermal geothermal development method of multilateral well closed circulation, comprises the steps of: dividing a geothermal reservoir into single layers according to geothermal reservoir geological conditions, wherein an upper single layer with a lower water temperature and a higher permeability is taken as a recharge layer, and a lower single layer with a higher water temperature is taken as a production layer; tripping a production casing, and injecting cement for well cementation; performing casing lateral windowing in a vertical hole corresponding to the recharge layer, and drilling several branch radial horizontal holes into the recharge layer; performing casing lateral windowing in the vertical hole corresponding to the production layer, and drilling several branch radial horizontal holes into the production layer; tripping a guiding pipe into the production casing of the vertical hole, with a depth thereof reaching a well section between the recharge layer and the production layer; tripping a packer at a guiding shoe to isolate the guiding pipe and an annulus of the casing from each other, so as to prevent geothermal fluid of the recharge layer and the production layer from being communicated with each other in the vertical hole.

3D panoramic camera with a built-in stabilzer

The present invention discloses a 3D panoramic camera with a built-in stabilizer, and relates to a panoramic camera. At present, a VR panoramic camera has the disadvantages of great difficulty in later-stage quilting, huge volume and unstable image. The present invention comprises an optical information acquisition sensing module and a stabilizer module, wherein the optical information acquisition sensing module comprises a lens mounting base and a plurality of lenses, the lens mounting base is cylindrical, the lenses are circumferentially and uniformly provided on an outer side of the lens mounting base, an inner chamber of the lens mounting base is a motor holding chamber, and the stabilizer module comprises a first motor, a second motor, a third motor and a stabilizer frame body, the second motor and the third motor are provided in the motor holding chamber within the lens mounting base, the first motor is located below the lens mounting base, and the first motor, the second motor and the third motor are connected with the lens mounting base through the stabilizer frame body to realize motion transmission. In this technical solution, the stabilizer is built-in, the volume is small, the workload of post-production is decreased and the difficulty in post-production is reduced.
