RMT测井技术及在断块油田挖潜中的应用

油田进入高含水或特高含水开发阶段,确定水淹程度,找出高剩余油层段已成为保持油田稳产和提高采收率的关键.RMT储层评价仪作为一种剩余油饱和度测井仪,它有2种可控操作模式:非弹性模式(C/O模式)和俘获模式(∑),其突出的优点是小直径、双源距、大晶体、多参数、多模式组合测井.在现河油区的整装块、复杂小断块、低渗油藏分别进行RMT非弹模式测井,通过实际资料分析,RMT测井技术在评价储层水淹特征,确定水淹程度以及求解剩余油饱和度等方面有其重要作用.

RMT Logging Technology and Its Application in Determination of Potential Remaining Oil in Block Oilfield

When an oilfield enters high or super-high watercut period, the key to keep oil production stable and enhance oil recovery is to determine the waterflooding degrees and find out the beds with high remaining oil. As a logging device for remaining oil saturation, RMT reservoir evaluation apparatus has two kinds of controllable modes i. e. , non-elastic mode (C/O mode) and capture mode ( )] with a character of small diameter, double source-detector separation, megacryst, multiparameter and multiple combined logging mode. RMT logging has been applied in all kinds of fault-block reservoirs of Xianhe oil production plant including complete fault-block, complex fault-block and low permeability reservoirs. Analyses of actual material indicate that RMT logging technique plays a very important role in many aspects such as evaluating reservoir waterflooding characters, determining waterflooding degrees and calculating remaining oil saturations.
