摘要:

在石油工业中，绞车被广泛用于钻井现场，实现起下钻、下套管、控制钻压等功能。在起下钻过程中若绞车运行不当易发生撞击井口、钢丝绳断裂等井下事故。根据石油钻井工况，设计了绞车测控系统，实现了对绞车钢丝绳张力、张力差分值、高度与速度等参数进行实时监测、对危险参数值进行实时报警等功能。基于STEP 7 MicroWIN V4.0平台设计了PLC程序，并使用WinCC flexible平台开发了人机交互界面。经过实验测试，可准确反映绞车运行参数，在石油钻井现场有实际的应用价值。

In the oil industry, winches are widely used in the drilling site to realize the function of trip, casing drilling pressure controlling and so on. In the drilling process, improperly operation may lead to crashing the wellhead and the rope breaking. According to drilling conditions, we design a winch control system, which realizes the real-time monitoring of rope tension, tension differential value, height and speed and other parameters. And it can alarm risk parameters. PLC monitoring program was designed by STEP 7 MicroWIN V4.0. And using the WinCC flexible platform we develop interactive interface. Experimental research indicates that the monitoring system can accurately detect and display the running parameters. This search in this paper can provide field application value for the oil drilling.
