摘要:
任丘油田1975年9月开采,1976年底开始深井注水,1977年油田内部地震频度增加,1978年出现小震群,1979年发生两次M33.0级以上的地震,到1981年9月,共记录到地震52个。#br#本文通过保角映射的方法,利用油田注采资料,计算雾迷山组油藏的地下液体流速,从而反演该区地下液体流动情况,反映注水采油与地震的关系。
Abstract:
The exploitation of petroleum was began in Sep.1975 in Renqiu oil field, the fluid injected to deep well from the end of 1976.In 1977, tho frequency of earthquakes was increased in the region of the oil field, and the swarm of small earthquakes occurred in 1978.Subsequently, two earthquakes with Ms>3.0 oceurred in 1979.Until Sep.1981, 52 earthquakes had been recorded.#br#In this paper, the method of conformal mapping was used and according to the data of fluid injection and oil exploitation the velocity of underground fluid flow in the group of Wumi mountain oil deposite was calculated.Thus the underground condition of fluid flow in this region could be inversed, and the relaton between injection-oil-exploitation and earthquakes was expressed.
