引起极电参数η_s增高的因素并非一定和油气因素相联系,只有同时采用视电阻率ρ_k方法,才能判别视极化率高异常和油气的关系。在油气田上方往往同时出现低电阻率异常和高极化率异常。用这种观点分析已知油区和预测新区,都有很好的效果。 The factors that cause the increase of the pole electrical parameter η_s are not necessarily related to the hydrocarbon factors. Only when the apparent resistivity ρ_k method is used can the discrimination between the apparent polarization anomaly and the hydrocarbon be determined. Above the oil and gas fields, low resistivity anomalies and high polarizability anomalies often occur at the same time. With this view of the known oil zone and forecast the new zone, have a very good effect.
