1975年海城7.3级地震和1976年唐山7.8级地震前后,在辽河、大港、胜利等油田都发现油、水井的动态异常,引起了人们的关注,油、水井在地震前出现短临异常动态,也为华北地区发生的多次中等地震所证实,1984年8月18日营口3.9级地震时,兴隆台油田的兴100号油井和兴10号注水井的动态异常是其中一例。一、兴隆台油田油、水井动态异常资料油、水井动态异常,是指油田开发过程中,非开发因素和人工措施引起的采油井或注水井的压力、产量、含水量或注水量的突发性大幅度的升降。 1.兴100油井兴100油井生产层位是新生界下第三系沙河街组一段中部第四号层。油层中部深度170
Before and after the Haicheng MS7.5 earthquake in 1975 and the MS7.8 Tangshan earthquake in 1976, the dynamic anomalies of oil and water wells were found in the oil fields of Liaohe, Dagang and Shengli, arousing people’s attention. The short-and-short anomalous dynamics of oil and water wells occurred before the earthquake , But also confirmed by many moderate earthquakes in North China. The dynamic anomaly of wells Xing’e No.10 and Xing’10 in the Xinglongtai oil field was one of the cases when the Yingkou Ms 3.9 earthquake of August 18, 1984 occurred. First, Xinglongtai oil and water wells dynamic anomaly data Oil and water wells dynamic anomalies, refers to the oil field development process, non-development factors and manual measures caused by oil or water injection wells pressure, output, water content or water burst A substantial rise and fall. 1.
