任丘油田注水与诱发地震的关系及应用

Relations Between Induced Earthquake Oilfield Flooding and Application

华北油田长期开发产生频繁的诱发地震活动,本文通过对油田地震活动特征的分析,并通过对任11井区的记录资料数据的统计,判断出注水是油田地震活动产生的根本原因,进而深入分析注水诱发地震的地质基础;从而找出对油田注水诱发地震可控性的措施并提出合理的对策,以有效地控制或减少油田地震活动,减轻地震灾害损失。

North China oilfield ＇s long-term development produce frequent trigger seismic activity,this paper analyses the characteristics of oilfield ＇s seismic activity,and through the summary of the data recorded statistic of 11 area in Renqiu,results that water flooding is the basic reason for triggering seismic activity,then further more explore the geological basis,so as to find out the controllability for oilfield water flooding and puts forward the measures to control the reasonable countermeasures,in oder to reduce seismic losses.
