Solar energy-based surface water warming compensation geothermal reservoir system

Abstract

The invention discloses a solar energy-based surface water warming compensation geothermal reservoir system which comprises a cyclone desander, an inlet of the cyclone desander is connected with an inlet of surface water through a pipeline, an outlet of the cyclone desander is connected with an inlet of a sterilization box through a pipeline, and an outlet of the sterilization box is connected with an inlet of a filter through a pipeline; an outlet of the filter is connected with an inlet of a water storage tank through a pipeline, an outlet of the water storage tank is connected with a secondary side inlet of a plate heat exchanger through a pipeline, a secondary side outlet of the plate heat exchanger is connected with a recharge well through a pipeline, and a primary side outlet of theplate heat exchanger is connected with an inlet of a solar heat collector through a pipeline; and an outlet of the solar heat collector is connected with a primary side inlet of the plate heat exchanger through a pipeline. According to the solar energy-based surface water warming compensation geothermal reservoir system, solar energy resources in non-heating seasons are used for increasing the temperature of the treated surface water and recharging the treated surface water into the recharging well, a supplementing effect is achieved on a heat storage layer, heat compensation is conducted on the heat storage layer, and thermal breakthrough is relieved.

Description

technical field [0001] The invention relates to the field of geothermal development, in particular to a solar energy-based surface water warming compensation geothermal reservoir system. Background technique [0002] The North China Basin is rich in geothermal resources, and the large-scale exploitation of resources has led to a decrease in the pressure of heat storage, which has affected the sustainable development and utilization of geothermal resources. Although the mining mode of "taking heat without water" using geothermal tail water recharge can alleviate the downward trend of heat storage pressure, the geothermal water resources wasted by the early "direct mining and direct discharge" can no longer be made up. In addition, due to the lack of scientific and reasonable layout of early geothermal wells, the spacing between production and irrigation wells often cannot meet the requirements of sustainable development, and there is a risk of thermal breakthrough.
