在已知油区进行激发极化法试验,得到了大量的“激电”参数资料。激电参数的异常特征与油气分布规律有密切的关系。根据高激电异常特征对新区的油气进行了预测,目前,在正的高异常区已有三口钻井证实了新区的含油性;在低异常区已有四口井证明无油气显示。这充分说明激电异常在直接寻找油气方面的作用。文章还对产生激电异常的原因进行了分析,认为在碳氢化合物富集的地区,产生高激电异常是完全可信的。
In the known oil zone, the excitation polarization test was carried out, and a great deal of information about the parameters of “electric shock” was obtained. The abnormal characteristics of the electrical parameters are closely related to the laws of oil and gas distribution. According to the characteristics of high-anomalous anomalies, oil and gas in the new area have been predicted. At present, three wells in the positive anomalous area have confirmed the oiliness of the new area; in the low anomaly area, four wells have proved oil and gas free. This fully shows the role of anomalies in the direct search for oil and gas. The article also analyzes the causes of the anomalies that generate the anomalies that suggest that it is perfectly plausible to generate high-anomalous anomalies in hydrocarbon-rich areas.
