Abstract

本发明是一种用于水平井随钻探层测距雷达的电磁波波速测量装置以及测量方法,主要适用于随钻过程中油层、煤层、及其它储层的层厚探测,在随钻过程中,实现实时测量电磁波在储层中的传播速度的功能,是水平井随钻探层测距雷达的核心技术之一。通过采用该装置及方法,可以较为精确得到电磁波在储层中的传播速度,再将此速度值结合传输时间测量值,即可得到储层的上下边界面,保证钻头始终在储层中钻进,保证了高钻遇率,从而提高了油气等资源的采收率。
The invention discloses an electromagnetic wave velocity measuring device and a measuring method for a horizontal well logging while drilling range radar. The electromagnetic wave velocity measuring device and the measuring method for the horizontal well logging while drilling range radar are mainly suitable for detecting layer thicknesses of an oil layer, a coal bed and other reservoir stratums in the process of drilling. In the process of logging while drilling, a function of measuring the propagation velocity of electromagnetic waves in the reservoir stratums in real time is one of the core technologies of the horizontal well logging while drilling range radar. By means of the device and the method, the propagation velocity of the electromagnetic waves in the reservoir stratums can be accurately obtained, an velocity value is combined with a propagation time measuring value, then an upper boundary surface and a lower boundary surface of the reservoir stratums can be obtained, the occurrence that a drill drills in the reservoir stratums all the time can be guaranteed, a high drill encounter rate can be guaranteed, and therefore a recovery ratio of oil gas and other resources is improved.
