摘要
核磁共振录井技术是目前唯一一项既能评价储集层物性又能评价流体分布的录井新技术。经过"十一五"期间的广泛应用与深入研究,在孔隙结构、孔喉分选性、储集层润湿性、储集层含水性等评价方面取得了可喜的进展。但面对越来越复杂的勘探对象及快速发展的钻井工艺,现有核磁共振录井技术的不足和不适应性也逐渐凸显出来。针对录井弱油气显示、低渗透油气层、页岩气录井评价的需求,提出了钻井液核磁、多维核磁、成像核磁的发展方向,对于核磁共振录井技术的发展、录井技术系列的完善、新能源新领域的开拓具有一定的指导意义。
At present, nuclear magnetic resonance logging technology is the only new mud logging technology which can evaluate both reservoir physical properties and fluid distributions. After a wide range of applications and in-depth study during the 'Eleventh Five-Year Plan' period, nuclear magnetic resonance logging technology has made an encouraging progress in evaluation of pore structure, pore throat sorting property, reservoir wettability, reservoir water cut and the other aspects. But with the increasingly complex exploration targets and the rapid development of drilling technology, the existing nuclear magnetic resonance logging technology is also gradually showing the deficiency and non-adaptability. In terms of the needs of mud logging weak oil and gas shows, the low permeability of oil-gas layers and shale gas evaluation, the author proposed the developing direction of drilling fluid NMR, multi-dimension spectrum NMR and NMR imaging, which has a certain guiding significance for the development of NMR logging technology, the improvement of mud logging technology series and opening up new areas of new energy.
