Abstract
The utility model provides a neogene-system hole type geothermy recharge system, which comprises an exploration well, two recharge wells, a geothermy pipe network device and a filter, wherein the geothermy pipe network device is respectively connected with the exploration well and the recharge wells; the filter is arranged between the recharge wells and the geothermy pipe network device; the well bottom perforations of the exploration well and the recharge wells are positioned in a Guantao group thermal reservoir stratum; and distance between the recharge wells and the exploration well in the thermal reservoir stratum is more than 200m. The neogene-system hole type geothermy recharge system has the beneficial effect of high recharge rate, and recharged water cannot cool the water temperature of the thermal reservoir stratum and a production well.
Description
Technical field
The utility model belongs to the development and utilization field of geothermal energy resources, especially relates to a kind of Neogene System pore type geothermal reinjection system.
Background technology
The development and use of geothermal energy resources have formed one; Geothermal heating particularly; The supporting inverted well of the recovery well that present geothermal heating is all taked makes the utilization that geothermal energy resources obtain continuing; But have following problem: 1, the amount of recharging of inverted well presents rapid attenuation, fast decay, the slow three phases of decaying, and makes the amount of recharging of last underground heat tail water be about 50% of the initial amount of recharging, greatly reduces the service life of geothermal field: 2, the GEOTHERMAL WATER that extracts of recovery well is after heat exchange; Be extracted most of heat energy; Therefore the recharge water temperature that loses most of heat is more much lower than former hot reservoir fluid temperature usually, injects former hot reservoir to the much lower tail water of relative temperature through inverted well, and the temperature effect of hot reservoir is inevitable; In the process of recharging the exploitation geothermal energy, main negative effect just causes the cooling of hot reservoir and producing well water temperature; 3, recharge middle can formation and float thing, microorganism, chemistry obstruction, reduce recharge rate, influence effective throughout the year operation of inverted well.
Summary of the invention
The purpose of the utility model provides a kind of recharge rate height and recharge water can not cause the Neogene System pore type geothermal reinjection system that hot reservoir and producing well water temperature are cooled off.
The technical scheme of the utility model is: Neogene System pore type geothermal reinjection system; The ground hot pipe network device that comprises a recovery well, two inverted wells, is connected respectively with recovery well and inverted well, be arranged on the filter between inverted well and the ground hot pipe network device; The shaft bottom perforation of said recovery well and inverted well is positioned at the hot reservoir of Guantao group, and said inverted well and the distance of said recovery well in hot reservoir are greater than 200m.
Said filter comprises coarse filter and fine filter, said coarse filter and said fine filter serial connection.
Between said filter and inverted well, also be provided with the blast pipe and the force (forcing) pump of serial connection with this.
Said coarse filter precision is 50 μ m, and said fine filter precision is 3-5 μ m.
Advantage and the good effect that the utlity model has are:
1, the geothermal utilization system adopts one to adopt two patterns of recharging of irritating, and the geothermal water reinjection rate reaches 100%, and that realizes GEOTHERMAL WATER adopts the filling balance, saving effectively geothermal energy resources, the maintaining heat reservoir pressure prolongs service life of geothermal field effectively;
2, in this hot reservoir, the migration distance of recharge water is short, can not cause the cooling of hot reservoir and recovery well water temperature;
3, the hot reservoir of this geothermal well is a porosity; Before GEOTHERMAL WATER is injected inverted well; Couple very much in love one cover is simple to operation, the circulating treating system of appropriate measures, need remove de-iron, calcium and bacterium at recharge water, improves recharge rate, guarantees effectively moving all the year round of inverted well.
