摘要
针对单向氧活化测井仪无法一次下井同时测量双向水流流量的缺点,研制了DS-Ⅰ型双向氧活化测井仪。该仪器采用一个中子发生器,从结构上缩短发生器的长度,实现了"单发双收"方式的双向氧活化测量,并加入了井温、压力、自然伽马等测井参数。通过推广应用,该技术提高了氧活化综合测井能力和效率。
DS-Ⅰ43mm bidirectional pulse neutron oxygen activation logging tool is developed to overcome the shortcomings of unidirectional pulse neutron oxygen activation logging tool such as unable measurement of bidirectional water flow at one run. The instrument uses one neutron generator to shorten the length of the generator from the structure to achieve a ″single-shot dual-income″ approach for the bi-directional measurement of oxygen activation. It can also get the parameters of the well temperature,pressure,natural gamma ray,etc.. The technology improves the comprehensive logging capability and efficiency of the oxygen activation logging.
