Abstract: 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.
