摘要
C/O测井可以利用BGO晶体探测效率高的特点,在其探测器部分放置两个探测器,称为双探测器C/O测井仪,长短源距两个探头所测谱数据进行补偿,有效地去除了井眼条件的影响,提高了测量精度和油水差值,更加有效地区分油水层。
The logging result of single crystal C/O spectral logging instrument (SCCSLI), which uses one detector, is influenced by bore hole conditions, such as bore hole diameter, fluid type, casing size, etc. These influences make the sensitivity and distinguishing ability of SCCSLI poor and its application difficult. The efficiency of BGO crystal is high, and dual BGO crystal C/O spectral logging instrument (DBCCSLI) uses two detectors, one is near the detector, and the other is far from the detector. The compensation of the two detectors greatly decreases the influence of bore hole conditions and improves the sensitivity and distingusshing ability between oil and water. Thus, usage of the C/O spectral logging instrument in lower porosity environment becomes possible. (
