摘要
对1985年12月28日山东省胜利油田角07井注水诱发地震序列的时序分析表明,该序列具有密集一平静相间的丛发特征;其地震频度随时间衰减,可由n(t)=1.46t^(-1.08)来表征;而最大地震之后较大地震的“等待时向’’Δt与它的发生时间t符合1g△t=0.9131gt—0.037关系。这与我国许多浅源地震序列的时间分布特点类似,本文就此进行了初步讨论。
The time-sequence analysis of the seismic sequence induced by water flooding in the jiao 07 well in Shengli oil-field in Shandong Province on 28 December, 1985 shows that the seismic sequence is characterized by clusters alternating with quietness; its earthquake frequency attenuates with time, which can be expressed as n(t)=1.46t-1.08; the 'waiting time' At of larger earthquake after the maxium and its occurring time t are consistent with the relaton of lg △t = 0.913 lg t-0.037. This is similar to the time-distribution features of many shallow earthquake sequences in China. A preliminary discussion is given here.
