摘要：天然气开采过程中常会出现并简积液现象，排水采气作业贯穿整个采气过程，导致日常维护管理工作繁重。针对目前自动投棒装置内部带压、操作存在安全隐惠等问题，设计了一套送程控制泡排棒自动投放系统，主要包括井口授棒装置、本地控制系统选程控制系统。整个系统的并口投棒装置上设计有压力平衡装置和投举监测装置，从而实现了投棒腔体与并口压力
机系统在现场进行试验，实现了定时定量自动投棒，系统稳定可靠。该系统的成功研制大大降低了工人劳动强度，提高了泡排效率，具有一定的雅广应用价值。

Abstract: Downhole fluid accumulation is a common phenomenon in the process of natural gas production, therefore water drain-age operation is required constantly, leading to heavy workload related to routine maintenance. Conventional automatic bar dropper sys-tems are characterized by deployment of intemal pressure and high risks in operation safety. To eliminate such problems, an innovative remote controlling automatic dropping system with foam-drainage bars has been developed. Major components of the system include wellhead bar dropper, local control system and remote control system. With pressure balancing devices and bar dropper monitoring de-vices deployed, the newly development system can effectively balance the pressure in the bar-dropping chamber and the wellhead pres-sure to protect the foam-drainage bar against damage caused by strong gas fiow around the wellhead. In addition, these devices may be used to monitor and record bar dropping processes. Host computer systems for the innovative remote controlling system have been tested in field to control the automatic bar dropper system safely and reliably. The newly developed system can effectively reduce manpower, enhance foam drainage efficiency and can be applied more extensively
