摘要
阐述了微电阻率扫描成像(简称FMI)测井方法在我国的应用和发展前景。微电阻率扫描成像测井能够对井筒周围地层介质直观、清晰、高分辨率地成像,有助于解决当前测井技术面临的三大地质难题:砂泥岩薄互层储层的有效划分,裂缝性油藏的裂缝和储集性能分析,复杂岩性油藏的参数评价。但也存在测速慢、费用高、定量解释效果差等不足。国际三大测井公司在这方面的研究起步较早,并取得了重要的成果.且早已投入商用.我国在这方面的研究也有很大进展,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,尽快推出更加适合我国地质特征的微电阻率扫描成像测井仪器和解释手段.
As a new-developed tool of geophysical well logging , Formation Microresistivity Image well logging is able to image distinctly the medium of the formation around the mineshaft ,and can help to solve the three geological difficulties faced by well logging technique:1.efficiently distinguish thin sandstones from thin shales .2. analysis of fractures and their ability of storage.3.evaluate parameters in complex reservoir. But it has many shortages:1.slow logging speed.2.too expensive 3.poor result in quantificationally interpretation. The three international companies of well logging initiated this research comparatively early and achieved many results, and have brought out commercial productions. Our country started this research a little late ,but has made great progress in recent years. In the future , we should overcome some theoretical and technical difficulties , and put out our better Formation Microresistivity Image tool and interpretation technique.
