取样式过环空找水仪在吐哈油田的应用

Sampling annulus water detector applied in Tuha oilfield

吐哈油田开发正处于高含水期 ,急需能够在高含水条件下测量油井含水率、流量等参数的测井仪器。针对这一需求 ,中国石油集团测井有限公司与大庆测试技术服务分公司合作开发了取样式高精度五参数环空找水组合测井仪。经标定实验与 1年 50多口井实际测试表明 ,取样式高精度五参数环空找水组合测井仪与常规过流式仪器相比 ,具有测量精度高、含水测量范围大、仪器刻度方便、启动排量低、由软件解释结果得出的解释准确度高 ,省时省力等独特的技术优势。仪器含水测量精度可达到±5 %以内 ,提高了含水参数资料录取的准确性和可信度 ,在吐哈油田产生良好的应用效果 。

This paper introduces the working priciple of the high precision five parameter annulus water detector. The real testing results show that it has particular advantages over the conventional through flow tool. Its water cut measuring accuracy is less than±5%. It improves the reliability of the water cut parameter data. This technology has great significance to the dynamic evaluation of an oilfield.
