摘　　要：EXCELL2000测井系统在实际使用过程中,由于测井电缆的长度、类型、温度以及上传速率等因素的影响,导致在不同条件下上传信号的失真和干扰程度也不一样,这就使得上传数据的解调和恢复工作变得非常复杂。文章主要讲述和分析电缆传输过程中信号失真情况及其恢复原理。EXCELL2000 logging system must correct distortions introduced by the logging cable. This function is complicated because of the tremendous variation in operating conditions, such as variations in line length, cable type, and downhole temperature. In this paper, the theory of the distortions and corrections for uplink data are analyzed mainly.
