REINJECTION IN SANDSTONE RESERVOIR IN TIANJIN
There exists two types of geothermal reservoir in Tianjin; porous sandstone fractured, weathered carbonate. 50％ of the exploration in Tianjin takes place in the geothermal sandstone reservoir. After years of research, the problem of reinjection into geothermal reservoir in carbonate rocks has basically been solved. But there still exists many problems with regards to recharge into reservoirs in Neogene sandstone, which mainly reflect the low and short duration of recharge. Therefore, solving the problems of sandstone recharge is important to the sustainable development and utilization of geothermal resources in Tianjin. In recent years, we have made some research on recharge well drilling technology, reinjection plug problems, and reinjection systems of the Neogene Guantao formation sandstone reservoirs. And we have acquired some good experiences.
