在准噶尔盆地的西北缘,实施了用于浅层油藏探测的复视电阻率法的资料采集。野外观测采用变型的偶极-偶极装置。资料处理采用基于Cole—Cole模型和Brown模型乘法组合的重整化谱参数相位交错拟合法。结果表明,CR法可以精细刻划在预定深度范围内探测目标的激电异常的纵、横向变化特征,并能提供有关油藏的多种信息,为钻井井位设计提供了可靠的地球物理依据。
In the northwestern margin of the Junggar Basin, data acquisition using the dipole resistivity method for shallow reservoir exploration was implemented. Field observations use variant dipole-dipole devices. Data processing is based on phase-interleaved renormalization parameter fitting method based on the combination of Cole-Cole model and Brown model. The results show that the CR method can finely characterize the vertical and horizontal variations of the target anomalies within a predetermined depth range and provide various information about the reservoirs and provide a reliable geophysical basis for the design of well locations .
