摘要
互补式电导探针阵列传感器设计是在以前所研究仪器基础上进行创新,采用轴向及周向互补的方式将电导探针传感器均匀分布,是一种主要应用于测量水平井油水两相含水率的电导成像方法,通过测量等效阻抗的变化来判断探针所处的位置,从而实现在水平状态下对油水界面位置的判别,同时给出持水率,并接通过探针所测量阻抗变化的规律判断油水界面附近的流型和流态。通过验证内外环之间互相补充,使得测量的精确率达到了理想的效果。
The complementary electric conductivity probe array sensor design is based on previous instrument foudation. It distributes sensors even through an axial and circumferential compiementary way, and it is a conductivity imaging method mainly used to measure two-phase water content rate, judge probe place through changes of equivalent resistance, thus distinguish the oil-water interface in horizontality, in the meanwhile hold the water rate, and judge the flow near oil-water interface by changes of equivalent resistance. Verify complementary between inside and outside ring, to get ideal effect on measuring accurate rate.
