The application of medium-deep geothermal heating pressureless recharge technology reduces the investment in surface underground equipment during the construction of recharge wells and improves the impact on the environment; it realizes the sustainable and long-lasting operation of recharge systems with a smaller number of recharge wells.
This technology has achieved the world-wide problem of recharge in mudstone areas.
This technology has also been popularized in the production process of sewage recharge in Sinopec Shengli Oilfield.
Our patented recharge technology increases the effective over-water cross-sectional area, greatly improves the recharge efficiency, solves the problems of how to reduce the mud in the sandstone substratum and reduce impurities in the recharge wells, and realizes the sustainable development and utilization of geothermal resources.
At present, the technology has passed the scientific and technological achievement appraisal of Dongying Science and Technology Bureau and is appraised as internationally advanced. It has been applied in many geothermal heating recharge systems, and after the actual operation test, the project system is stable in operation and technologically advanced.
