摘要
目前石油行业钻机传动系统的设计计算偏保守,动力容量配置偏大,运行操作中能量状态缺乏检测手段。石油钻机的起升系统是典型的周期变化的具有冲击特性的势能负载,为实现势能回收、储存和有效利用,在本研究中提出新的检测方案并研制出检测装置。该装置可全面准确获得钻井起下钻具作业时钻机传动系统的运行状态变化、功率变化、能量转换的实时特性,为研究钻机系统能量回收、利用和动力调峰运行技术提供基础实验数据。通过对实验结果和数据的分析,发现钻机的柴油机动力配置偏高,可通过减配或改进传动结构来提高利用率。
At present, in the petroleum industry, the design of the drive system for drilling rigs is largely conservative for safety reasons. A large redundant power capacity configuration is often adopted, and there is a lack of detection means to monitor the energy state during operation. The lifting unit of an oil drilling rig relies on potential energy load, which undergoes an cyclic operation and has the potential to recover, store and use the energy. In this study, a new detection device is proposed and developed. With such a device, real-time characteristics of the transmission system, power change and energy transformation are obtained experimentally during operation. Based on the experimental results and data analysis, it is found that the diesel engine adopted for the drilling rig is on the high side, leading to resource waste. There is therefore a potential for reducing the waste through better matching and/or improvement of the transmission system.
