More Information
Summary:The utility model discloses a well type capable of effectively utilizing geothermal resources, which comprises a straight well section, an inclined well section and an annular packer, and the straight well section forms an annular space and an inner hole; one end of the inclined well section is communicated with the annular space of the straight well section, and the other end of the inclined well section is communicated with an inner hole of the annular horizontal well section; and the inner hole of the annular horizontal well section is communicated with the inner hole of the straight well section through the inner hole of the annular packer. The well type structure of the single straight well and the well bottom annular horizontal well is adopted, the unit well drilling cost can be greatly reduced, meanwhile, by prolonging the length of the annular horizontal well section located at the well bottom, the heat exchange area of a working medium in a closed-loop pipe body in a high-temperature area is enlarged
