摘要: 电极法复电阻率测井技术是以岩石复电阻率频散特性为理论依据,从岩石物理性质的理论和实验研究的基础上发展起来的一种新型电测井方法,该方法能同时检测岩石电阻率、低频介电常数和频率响应特性.电极法复电阻率测井的实现是在双侧向仪器的基础上增加一个频率大约为10kHz的高频通道,并检测其复电阻率模值.其测井资料的解释用岩心实验建立的复电阻率频散模型作为正演模型,对测量到的低频实部电阻率和高频模值电阻率进行反演求出地层的含油气指示参数,从而评价地层的含油气特性.应用该方法进行了现场测井和资料处理,结果表明其方法具有可行性.

Abstract: The complex resistivity well logging with electrode antenna was developed on the basis of the theoretical and experimental study of rock physical property.The basic theory of the logging method is the electrical dispersion property of rock.The resistivity,permittivity and the dispersion of formation can be measured using a logging tool with a high-frequency(about 10 kHz) channel.The logging data can be interpreted by the inversion algorithm.The complex resistivity dispersion function from core experiment is taken as the forward model.The real component resistivity of low frequency and the module of complex resistivity of high frequency can be inversed to calculate the apparent water saturation and evaluate the oil-bearing property of reservoir. Field application of this method proved its possibility in log interpretation.

Key words: complex resistivity well logging, dispersion property, rock resistivity, formation evaluation, mathematical model
