德莱赛—阿特拉斯公司为了精确、快速、高效的取得测井数据,在3700数控测井系统(CLS)中,研制了一种“一次组合测井系统”(SLAM)。该系统可按照测井需要一次组合仪器下井。采用3503井下脉冲调制编码发送器(PCM),将井下信号进行编码、串行传送至地面。在地面,将信号变为并行数据,送计算机处理。
Dresser-Atlas has developed a “One-Logging System” (SLAM) in the 3700 CNC Logging System (CLS) for accurate, rapid and efficient logging data acquisition. The system can log well once the combination of instruments down. 3503 downhole pulse modulation code transmitter (PCM), downhole signal encoding, serial transmission to the ground. On the ground, the signal into parallel data, sent to the computer processing.
