摘要
1979年以来,天津地区先后有9口石油深井出现了“井管突升、地面崩裂”异常现象。本文通过这9口井的基本情况、分布特点、异常类型等方面的分析,对这一现象产生的机理进行了研究,认为:这一现象的发生是由于地面局部沉降的结果,并对其进行了数值模拟、力学解释;同时提出了安定社会的三项对策
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 fu ndame ntal conditions,distributing features and anomalous types of 9 oil wells are ana lysed,the producing mechanism of these penenomena is studied. We consider these ph enomena occurred as a result of partial ground subsidence and is imitated using numerical value method,explainned in mechanics.At the same time,3 countermeasure s are raised for maintainning society.
