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M_33.0级以上的地震,到1981年9月,共记录到地震52个。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。 Renqiu Oilfield was mined in September, 1975 and deep well water injection started at the end of 1976. The frequency of earthquakes increased in 1977 and small earthquakes occurred in 1978. Two earthquakes of magnitude M_33.0 occurred in 1979. By September 1981, A total of 52 earthquakes were recorded. In this paper, by using the method of conformal mapping, the underground liquid flow rate in the Wumishan Formation reservoir is calculated by using the injection and production data in the oilfield so that the fluid flow in the underground area can be inverted and the relationship between waterflooding recovery and the earthquake can be reflected.
