双频介电测井方法与实现

The method and compliment of dual frequency dielectric logging

介电测井是一种测量地层中电磁波传播速度和相位差的测井方法,能计算出地层的介电常数和电导(阻)率,在油田广泛推广用于评价地层孔隙度和含水饱和度,以区分油、水、气层.本文结合在国产数控测井地面系统配接Atlas1531/1532介电测井仪的经验,详细介绍了介电的测井原理和数据处理,给出了测井方法的具体实现和应用.该方法已经在多种地面系统和测试台架得到验证,通过现场测井取得良好的应用效果.

Dielectric logging is a special logging method, it can measure the speed and phase difference of electromagnetic and gets the dielectric constant and conductivity or resistivity of formation. It has been widely used in the oil field to evaluate the porosity and saturation of the formation. The purpose of this paper is to describe the logging method and principle, the data transmitting and processing, the compliment has also been given in the computerized logging system. We have used many methods to get the best results.
