摘要
核磁共振测井以全新的原理,提供了一套全新的信息和响应关系,能够对地层油气评价的基本问题,进行全新的解答.胜利油田自1996年开始使用核磁共振测井以来,至今已经积累10余年的测井应用经验.总结核磁共振测井技术在胜利油田的发展应用,其发展经历了三个阶段:初步探索阶段,研究应用阶段和完善深化阶段.在初步探索阶段主要是以储层识别以及孔隙度、渗透率、饱和度等岩石物理参数为主;在研究应用阶段主要是利用T2分布形态进行流体识别和孔隙结构研究;完善深化阶段则是提高解释评价精度,针对勘探开发中的评价难题深化地质应用.目前,核磁共振测井技术在胜利油田的应用已经逐步完善成熟,已成为提高油田勘探开发效益必不可少的手段.在储层评价、参数计算、流体识别中发挥了重要作用,尤其是在单纯依靠常规测井难以进行流体识别的低电阻率/电阻率低差异、低孔隙度、低渗透率、砂砾岩体、复杂岩性等油气藏评价中发挥了独特的作用.
By right of new theory, Nuclear Magnetic Resonance （NMR） logging provides an abundant of information and response relationships, and gives good solutions to basic problems of formation evaluation. Since NMR Logging was introduced in 1996, Shengli Oilfield has accumulated ten-year＇s experiences. The development of NMR Logging experiences three phase： probing phase, studying and applying phase, and improving and elevating step. In first phase, reservoir identification and petrophysics parameters calculation is predominant. Second step is as fluid typing and pore structure, and now NMR Logging application has enter the third phase, the target in which is geology appli- cation pointing to exploration problems. NMR Logging technology has become indispensable means of elevating exploration benefit, NMR logging has played great roles in reservoir classification, parameter calculation and fluid typing, especially in difficult reservoirs for conventional logs such as low resistivity/low difference resistivity, low porosity and low permeability and complex reservoirs.
