复电阻率法在浅层稠油油气检测中的应用

复电阻率法是近几年发展起来的一种频率域电偶源地面电法勘探方法，是电磁勘探方法中唯一的能直接指示油气藏的方法。复电阻率法在油气勘查上，主要用于检测、评价工作区域内的局部圈闭或异常是否含油。提供钻探靶标，提高钻井的成功率，降低勘探、开发风险和成本。该方法曾于1999、2000、2002年在新疆油田准噶尔盆地腹部进行过试验、试生产及大面积生产工作，2003年在克拉玛依九区浅层稠油油田应用初步反演和各类资料处理结果，与实际生产井的油水层对比结果一致，取得了较好的地质效果。

Complex resistivity for shallow heavy oil detection

Complex resistivity method is a surface electric prospecting method by using frequency domain couple source developed in recent years. It is the only electromagnetic prospecting method that can directly indicate oil and gas reservoir. Complex resistivity method is mainly used to test and evaluate whether local trap or anomaly within a study area bears oil, to provide drilling target, to improve drilling success ratio, and to reduce the risk and cost of exploration and development. This method had been tested, pilot tested and large-scale used in Junggar Basin, Xinjiang oilfield in 1999, 2000 and 2002. In 2003, in block 9 shallow heavy oil field of Karamay, preliminary inversion and various data processing result conform to the correlation result of oil and water layer in production wells.
