A Feasibility Study on Gravity Power Generation Technology by Virtue of Abandoned Oil-Gas Wells in China

In the future, there will be more and abandoned oil-gas wells with exploitation of onshore oilfield resources. However, large height difference in can used as building blocks for gravity power generation, thus maximizing economic value wells. this study, a scheme generation by virtue spud-in casing depth is proposed, model based on established. The parameters benefits energy storage are calculated Huabei oilfield, Daqing Xinjiang oilfield. It shown that density discharge time system suitable distributed generation. addition, fast response characteristics verified, which makes correcting continuous sudden frequency voltage changes grid but not arbitrage under high number annual cycles. Furthermore, leveling cost economical analysis work provides significant investigation feasibility using
