We took the example of the Yu 01 well, which is near the epicenter of Heze M S 5.9 earthquake, calculated the response rate and loading and unloading response ratio of two kinds of the earth tides of it. The response rate and response ratio before the earthquake had the variation of increase.展开更多

According to these elements, correction has been conducted, and find that the correction according to the level of wind speed has the best correction effect.展开更多
