摘　　要：随着油气田开发的日益复杂,对勘探的要求越来越高,测井技术要求仪器提供的信息更全面、更准确,客观上要求我们必须提供大信息量、高精度、高时效和高可靠的新一代测井设备,即开发出成像测井系统。在各种成像系统中一个共同的关键技术就是高速电缆遥传系统。研制高速电缆遥传系统目的就是完成地面仪和井下仪器之间的高速、大数据量的数据传送。高速电缆遥传系统与井下仪器的通讯是通过高速电缆遥传系统中的井下仪器总线控制器(简称BCU)与遥传接口(简称RTU)之间的通讯来完成的。With increasing complexity of gas oil field exploitations, exploring requirements are more strictly in the future. Measuring well techniques which require instruments to provide information is becoming more and more comprehensive and accurate. So we must offer new generation measuring well equipments that is more precision, more efficiently, reliably and a great deal of communications, which are imaging measuring well systems. The important technique in the imaging measuring well systems is high speed cable remote system.
