Abstract： By controlling the process of casing， a new type of top-drive casing system has reached the control targets of reducing the capitalized cost and achieved safety， high efficiency purposes. The performance of top-drive casing running hydraulic system directly influences the performance and operation of the system. Testing the performance of the system needs hydraulic simulation. Based on the software AMESim， the hydraulic system model of top-drive casing running system has been set up and simulated. The main purpose is reducing the cost of the top-drive casing running system test and saving time. The results of simulation and theoretical calculation value have been analyzed and compared. This process is required to verify the designed hydraulic cylinders to meet the requirements.

引言

顶驱下套管装置是一种结合顶部驱动钻井系统，用在下套管作业的集机械、液压于一体的自动装置。利用顶驱下套管装置是下套管作业中未来发展的趋势。该装置国外主要生产商是NOV、Tesco和Weatherford，国内是北京石油机械厂[1]。由于北京石油机械厂和Tesco顶驱下套管装置无重力补偿装置;Weatherford的卡紧力为定值易损伤套管;NOV的需要单独设计配套的液压和电缆管汇的缺点。新的顶驱下套管装置的重力补偿液压系统是整个装置中关键的系统，主要起到保护装置的作用。重力补偿液压系统的液压缸可以抵消一部分重力，从而避免上扣时损伤套管螺纹。并可以精确施加向下推力[2]。利用AMESim液压仿真软件对新型顶驱下套管装置的补偿液压系统进行仿真，能检验设计的补偿液压系统是否合理，是否达到设计要求，大大缩短设计时间。……
