摘要

由于稠油具有黏度大、密度高等特点,采用常规储层的核磁共振测井观测模式很难得到理想结果。 基于核磁共振测井原理和稠油储层的特性,根据地区实验数据,估算了稠油储层的等待时间、回波间隔、 回波个数等核磁参数,并通过优选观测模式,获得了有效的核磁共振测井资料。对利用该方法获得的新疆 JMS 地区的核磁共振测井资料进行稠油储层测井解释,取得了较好效果。

Abstract

Due to the high viscosity and high density of heavy oil, it is difficult to obtain good result by using nuclear magnetic resonance logging observation model for conventional reservoirs in heavy oil field. Based on the principle of nuclear magnetic resonance logging and characteristics of heavy oil reservoir, this paper discussed how to choose the parameters of TW , TE and NE, and obtained effective log data by optimizing observation model for heavy oil reservoir. Taking JMS heavy oil area as an example, the nuclear magnetic resonance logging data were applied to carry out log interpretation for heavy oil reservoir, and good results have been obtained.
