It helps to offer spacing parameters in optimizing dual-detector C/O logging tool in slim holeto investigatethe relationship between response of C/O log and spacing in slim hole with numerical simulation.
通过比较分析,得出小井径双源距C/O能谱测井响应对源距有很强的依赖性;当源距的范围在26~34cm和50~62cm之间时,C/O测井分层能力强,同时受井眼影响小,因此,短源距的选择范围是26~34cm,长源距的选择范围是50~62cm。
6) wells with small diameters
