Abstract: Reservoir monitor tool (RMT) is a new type carbon/oxygen (C/O) log instrument. The logging quantities and sensitivities of RMT are greatly better than other C/O log tools by using two bismuth germanate scintillators. Based on the fundamentals of C/O log tools,the structures and log principles of RMT were investigated. A mathematical model for determine remaining oil saturation using RMT logging interpretation was established. The corresponding software of RMT logging interpretation was developed by using the FORWARD logging interpretation software platform. The comparison of interpretation results of RMT and coring and other well testing results indicates that the established mathematical model and the interpretation methods of RMT logging data procession are credible and feasible.

摘要： 油藏监测仪(RMT)是目前各种碳氧比测井仪器中计数率和测量精度最高的一种新型的测井仪器。根据碳氧比测井的基本原理,研究了RMT测井仪器的结构和测量原理,建立了RMT用油藏监测仪测量地层剩余油饱和度的数学模型,并在FORWARD测井解释平台下开发了相应的RMT测井解释软件系统。对现场RMT实测资料的处理结果与取心及其他测试结果的比较分析表明,所建立的解释模型和处理方法切实可行,测井解释符合率高。
