摘要: 新疆魏家沟新05井是一个深2260m的石油探井,自1978-2004年的27年间,发生了9次井喷现象。当井喷发生时,地下水携带大量的天然气和少量的油花、油腊从井中猛烈地喷射出来,水柱喷射的最大高度达10m以上,井喷无明显的周期性特征。依据震例总结的经验,筛选了一批地震,以新05井发生井喷现象后未来半年为限,研究了所筛选的地震与井喷现象的对应关系,发现震中距100km范围内发生5级地震的对应率为33.3%,100~300km范围内5级地震的对应率为零,500km范围内6级地震的对应率为零,1000km范围内大震或强震群的对应率为60.0%。

Abstract: The new No.5 well is a petroleum well with 2260m depth, and it spewed nine times from 1978 to 2004. During a blowout, a lot of natural gas with a little of oil and oil wax were spewed together with underground water; the tiptop height of water column was more than 10m. Based on the statistics, the blowout phenomenon of well did not have obvious cycle characteristics.Based on the analysis of earthquake cases, the authors selected the earthquakes that occurred in the half year after the No.5 well had spewed to study the relation between earthquake and blowout of well. The result shows that the corresponding rate for M5 earthquake is 33.3% in the range of 100km, 0 for M5 earthquake in a range of 100km to 300km, 0 for M6 earthquake in the range of 500km, and 60% for large earthquake or strong earthquake swarm in the range of 1000km.The probable reason was explained. Finally, the authors raised their standpoint about earthquake tendency concerning the blowout of No.33 well in Wusu and the new No.5 well again in 2005.
