The invention discloses a double-pump cooperative driving logging winch hydraulic transmission system which comprises an electric control system control unit, and the input end of the electric control system control unit is connected with a signal line of a cable tension sensor. The output end of the electric control system control unit is simultaneously connected with the electric control variable pump I, the electric control variable pump II, the hydraulic control valve bank and the electric control variable motor, the electric control variable pump I and the electric control variable pump II are respectively interconnected with the hydraulic control valve bank, and the other output end of the hydraulic control valve bank is connected with the electric control variable motor. According to the system, firstly, full coverage of high-speed and ultra-low-speed ranges of logging of a deep well exceeding ten thousand meters is achieved, and stable and reliable ultra-low-speed performance can be provided; and secondly, the oil supply pressure of the oil pump is adjusted through the electric proportional control valve, and automatic cooperative control over the logging winch and the power winch during logging operation of the deep well larger than ten thousand meters is achieved.

    本发明公开了一种双泵协同驱动测井绞车液压传动系统,包括电控系统控制单元,电控系统控制单元的输入端与电缆张力传感器的信号线连接,电控系统控制单元的输出端同时与电控变量泵一、电控变量泵二、液压控制阀组、电控变量马达连接,电控变量泵一和电控变量泵二分别与液压控制阀组互联,液压控制阀组的另外输出端与电控变量马达连接。本发明的系统,一是实现了超万米深井测井的高速与超低速范围全覆盖,且能够提供稳定可靠的超低速性能;二是通过电比例控制阀调节油泵供油压力,实现超万米以上深井测井作业时测井绞车与动力绞盘的自动化协同控制。
