Successful development of air storage seal evaluation device 　　

Recently, the scientific research personnel of the Zhongyuan Oilfield Petroleum Engineering Technology Research Institute developed an experimental device for the plugging and sealing evaluation of oil and gas reservoirs, and evaluated the sealing performance of the plugging agent for the old well of the Wen23 gas storage.
Experiment to ensure the safe and stable operation of the gas storage
.

"This experimental device can simulate the influence of periodic stress changes on the sealing performance of the gas storage during the operation of the gas storage, and evaluate the gas storage under the operating pressure, the plugging agent and the formation, the plugging agent and the wellbore, and the plugging agent and the formation wellbore.
The effectiveness and effective period of the overall plugging reflect whether the gas tightness of the plugging is good when the oil and gas reservoir type gas storage is in operation, which is conducive to the optimization of the performance of the plugging agent formulation by scientific researchers and guides the on-site implementation of the gas storage.

Before the gas storage is built, it is necessary to plug the stratum and wellbore of the old wells that have encountered the gas storage strata.
