The Study of Anomalous Mechanism and Social Influnce Countermeature of Well Tube Abrupt Rise and Ground Burst In Oil Deep Well Observation for Earthquake

Since 1979,the anomalous phenomena of well tube abrupt rise and ground burst occurred in 9 oil wells distributing in Tianjin area.In this paper,the fundamental conditions,distributing features and anomalous types of 9 oil wells are analysed,the producing mechanism of these penenomena is studied. We consider these phenomena occurred as a result of partial ground subsidence and is imitated using numerical value method,explainned in mechanics.At the same time,3 countermeasures are raised for maintainning society.
