自动管具举升系统的研制及应用
|
摘要
为有效解决钻井现场管具上钻台和甩钻作业中存在的工人劳动强度大、危险系数高以及作业效率低等问题,研发了自动管具举升系统。该系统通过采用调节式钻井管具排放架、倾斜机构、管具推出机构、四连杆滑块机构和推送小车等,实现了钻井管具在地面与钻台面之间的自动、安全、高效举升与甩钻自动化智能操作。采用遥控技术及PLC逻辑控制技术,以PLC为核心,主控制器辅以软件程序的数字控制系统,操作模式分为无线遥控和有线控制2种,作业时,操作人员在离猫道有一定安全距离的地方操控整个系统,避免了管具举升过程中由于管具意外滑落伤人事故的发生,满足钻井设备HSE的要求。现场应用结果表明,该系统技术先进、结构合理、自动化程度及工作效率高;可显著减轻现场工人的劳动强度,实现管具处理的无人化作业,安全性好。该系统的研制为钻井现场提供了一种自动化程度高且安全高效的作业设备。
To effectively address the issues of current field operations of laying pipe on and down the drill floor like high labor intensity,high risk and low efficiency,a automatic pipe lifting system has been developed. The system fully achieves automatic,safe and efficient lift of drill pipe between ground and drill floor,and automatic intelligent control of pipe laydown by using adjustable pipe racking,tilting mechanism,pipe push-out mechanism,four-bar linkage slider mechanism and push trolley. This system,taking PLC as core,adopts remote control technology and PLC logic control technology. The main controller is assisted by software program and digital control system. The operation mode consists of wireless remote control and wire control. The operator could operate the whole system with certain safety distance from the catwalk to avoid personnel injure caused by accident pipe falling during pipe lifting,which fully meet the HSE requirement for drilling equipment. Field application results showed that,the system,with advanced technologies,reasonable structure,high degree of automation and efficiency,can significantly reduce labor intensity and achieve safe and unmanned pipe handling operation.
