| 摘 要： | 提出了一种利用核磁共振技术进行现场岩屑油层物理参数定量分析的新方法。对比分析了核磁共振岩屑与岩心分析的异同，对核磁共振现场岩屑分析的可行性进行了室内实验研究，同时给出了利用核磁共振技术确定岩屑孔隙度、渗透率等重要油层物理参数的方法，该方法利用流体在不同岩石孔隙中的弛豫特性来获得岩石物性参数；在青海油田、吉林油田、冀东油田开展了核磁共振岩屑分析技术现场应用研究，将现场核磁共振岩屑分析得到的孔隙度、渗透率等储集层参数与常规取心分析及核磁测井得到的相应结果进行了对比分析。图3表3参7 |

| Abstract: | A quantitative method of determination of rock properties from cuttings by using Nuclear Magnetic Resonance technology is presented, for which the rock relaxation could be achieved by using the feasibility of fluid in pore. Differences between Nuclear Magnetic Resonance cuttings analysis and Nuclear Magnetic Resonance core analysis are studied. The method to determine the rock properties such as porosity. permeability, etc, from cuttings by using Nuclear Magnetic Resonance technology is also presented. The on-.site application of Nuclear Magnetic Resonance of cuttings is carried out in Qinghai, Jilin and Jidong Oilfield, suggesting that the NMR technology on cuttings and conventional core analysis matches well. |
