电磁波测井的现状和发展趋势

The situation and progress of electromagnetic well logging

作为地球物理测井重要手段之一的电磁波测井能够同时测量井周地层的电导率和介电常数,而这些常数对于评价地层的含油性是至关重要的.前苏联在这方面的研究起步最早,并取得了重要的成果.而目前投入商用的主要美国等石油公司的产品.我国在这方面的研究也起步较早,但由于技术上的原因,目前还没有投入商用的产品.在未来的发展中,应针对一些理论和技术上的难点分别突破,尽快推出我国自己的电磁波测井仪器和解释手段.

As an important tool of geophysical well logging, electromagnetic well logging is able to measure the conductivity and dielectric constant of surround formation, which are very important to evaluate the oil saturation. Former Soviet Union initiated this research very early and achieved many results. But the current commercial products are all from United States and other countries. Our country started this research early, but there are no commercial products. In the future, we should overcome some theoretical and technical difficulties, and put out our electromagnetic tool and interpretation technique.
