在准噶尔盆地BKQ油田实施了一条剖面的频率域激发极化法的资料采集.设计测线穿过2口开发井(一口油井,一口干井).野外观测采用变型的偶极-偶极装置.在资料处理过程中,采用重整化谱参数相位交错拟合法分离激电谱和电磁谱.试验结果表明,油气藏上方存在明显高于正常地层的激发极化异常,激电谱相位、视极化率和零频电阻率均呈相对高值.试验也观测到视电阻率的静位移现象.

In BKQ Oil field of Jungar Basin, a method of complex apparent resistivity (CR) was used for oil and gas pros pecting and for reservoir detecting. Dipole-dipole configuration was used for data acquisition. In order to separate SIP and SEM, a new technology based on the multiplication combination of Cole-Cole model and Brown model were used for data processing. It was called reforming spectrum parameter phase stagger fit method. Test result indicates that CR can be used for studying the variety of characteristics of IP anomaly along vertical and lateral directions in the specified depth range for providing creditable geophysical evidence for borehole design. The predicted IP is confirmed by drilling.
