【摘要】 文本研究了玉门老君庙油田近年来形变隆起的成因,认为,油田注水量超过开采量而引起形变隆起和套管错断,形变隆起幅度和套管错断位置与注水量大小、构造部位有关。进而论证了超采注水造成的局部构造活动与诱发地震的关系,认为注水诱发地震需具备一定的构造条件,而老君庙油田不具备此构造条件,虽注水压力很大也不会诱发地震,乃以蠕滑形式释放了能量。更多还原

【Abstract】 The origin of deformation and uplift, in recent years at Laojun-miao Oil Field, Yumen, Ganshu Province is studied in this paper. It is recognized that deformation and uplift and the offset of oil tube occurred when the volume of pumping water exceeded the volume of exploited oil in oil field, the range of deformation and uplift and the locality of the offset of oil tube are associated with volume of pumping water and the structure position.Furthermore, the relations between regional tectonic activity due to exceeding pumping water and induced earthquake are identified. It is assumed that induced earthquake by pumping water must be under certain structural conditions, while Laojunmiao Oil Field has not this condition, there is no induced earthquake occurred although the pressure of pumping water is very high, and che accumulated energy is released in a form of creep slip.更多还原
