井筒中剩余油饱和度监测技术最新进展

如何获得精确的剩余油饱和度参数是目前公认的世界性技术难题之一,也是油藏工程师们普遍关心的问题。套管井剩余油饱和度测井仪都是利用中子与地层物质相互作用这一特性来设计的,因此,要想获得精确的储层参数,不是改变仪器的基本的测量原理,而是从仪器的设计、工艺、数据采集方式、采用晶体材料、中子管及解释模型等来达到目的。具有代表性的生产测井新技术主要有:康普乐公司的PND测井技术;斯伦贝谢公司的RST测井技术;哈里伯顿公司的RMT测井技术;阿特拉斯公司的RPM测井技术及国产的DDCO-2测井技术等。

New Progress on Technologies．Monitoring of Surplus Oil Saturation Degree in Well Tube

How to acquire accurate remaining oil saturation ia known as a problem worldwide, and also an universally concerned problem by the reservoir engineers. The remaining oil saturation logging tool for cased wells are designed by the effect between neutron and strata matter. So design and technology of tool, data acquisition method, crystal material, neutron tube and interpretation model , not changeing basic measuring principle, should be analyzed. There are some representative new production logging technology, such as PND of Complior, Reservoir saturation tool of Schlumberger, Reservoir monitor tool of Halliburton, Reservoir performance monitor of Atlas and Dual-spaced carbon/oxygen logging tool in China.
