岩石电性参数(电阻率、介电常数等) 频散是岩石介质的重要特征之一,利用岩石电阻率频散特性发展起来的测井———复电阻率测井方法,有望改善和提高陆相沉积地层油气评价的质量和能力。应用电性参数的频散性进行地层评价是目前定义的复电阻率测井的主要特点。从电阻率测井基本原理出发,介绍了复电阻率测井的理论依据及测井原理,仪器性能指标及适用范围,通过在胜利及中原油田部分井上的测井解释实施,取得了较好效果,证明了复电阻率测井方法的有效性,特别是对低水淹层的解释上与油藏动态生产特征符合率较高,该项测井技术有着良好的应用前景。

The discrepancy of rock electricity parameters is one of the important characteristic of the rock mediums , it has developed a new well logging method-omplex electric resistance rate logging. This method can improve and increase the geologic strata evaluation quality and ability in land deposit reservoir. By using of the discrepancy property to make a strata evaluation is the main character of this method. Beginning from the basic principle of electric resistance rate logging , this article introduced the theoretical basis and principle of complex electric resistance rate logging method , apparatus function index and appliance scope. The logging method of complex electric resistance rate , by practicing its explanation result in some wells in Shengli and Zhongyuan Oilfield , obatained a good result , demonstrated its usefulness , and especially in the explanation to low flood layers had a higher match rate with the reservoir development production character. This logging method has got a good appliance foreground.
