新疆塔河特低孔低渗油气藏核磁共振测井应用基础实验

Basic Experiment of NMR Logging Application in Ultra-low Porosity /Low Permeability Reservoirs in Tahe Area of Xinjiang

在新疆塔河特低孔低渗油气藏进行了核磁共振测井应用实验研究。分析了塔河地区特低孔低渗油气藏实验室核磁共振实验测量结果,并与其他常规测井资料进行了对比。对比分析表明,NMR是基质孔隙度和束缚水评价的有效方法,常规测井与NMR的综合可以反映裂缝的影响。

An application experimental study of NMR logging in Tahe ultra-low porosity and low permeability reservoirs in Xinjiang is conducted. A laboratory detecting result of NMR experiment of the ultra-low porosity and permeability reservoirs in Tahe Area is analyzed, with which conventional logging data are contrasted. Analysis of the contrast shows that NMR is an effective method of matrix porosity and irreducible water evaluation. The effect of fracture will be revealed by integrating conventional well logging with NMR.
