摘要
注硼中子寿命测井是一项水淹层测井新技术 ,对老油田的产层分析评价、剩余油含量估算等方面发挥了重要的作用。但测井施工时 ,往往由于注硼工艺不当导致硼酸的渗吸量难以准确反映地层可动水的含量 ,从而产生解释上的困难和误区。在渗流与扩散理论相结合的基础上 ,结合华北油田的施工实践 ,介绍了确定注硼管柱、硼酸用量、注硼压力以及硼酸扩散时间的基本原则和实际经验 。
Boro injection neutron lifetime logging is a new logging technology for water flooded zone. In recent years, it plays an important role in analysis and evaluation of producing formations, estimation of the residual oil in many old oilfields in China. But in logging, sometimes, the osmotic quantity of boric acid can not accurately reflect moveable water because of improper boride injection techniques, thereby producing difficulties and mistakes in interpretation. On the basis of combining seepage and dispersion theories, together with the logging practice in Huabei Oilfield, introduced in this article are the basic principle and practical experience of defermining pour boride tube strings, dosages of boric acid, pressure of boride injection and diffusin time of boric acid, which provides some new ideas for optimum boric acid injection design.
