【摘要】：针对国外引进柱塞气举技术采用定时开关井生产方式,没有自动调参功能,运行制度需人工设置的缺陷,开发了一种气井柱塞气举生产的自动运行方法。该方法将柱塞最佳上升时间长度设置为目标上升时间,通过控制器对柱塞实际上升时间的分析,自动调整开、关井时间,保证柱塞实际上升时间接近于目标上升时间,使气井生产制度自动趋于最佳,实现对柱塞气举排液采气过程自动化的控制管理。并设计了一种性能更优的一体化柱塞控制器。这种新型柱塞排液采气技术已在长庆气田某区块整体应用75口井,经过2年多的实践检验,能够根据柱塞到达情况,自动对生产制度进行优化、调整,大幅降低工作量,实现了柱塞气举井运行自动控制和精细管理。基于柱塞上升时间自动优化工作制度的控制方法为长庆气田柱塞气举排液技术大规模推广应用提供了技术保障。
[Abstract]:In view of the defects of imported plunger gas lift technology using timing switch well production mode without automatic parameter adjusting function and manual setting of operation system an automatic operation method of gas well plunger gas lift production is developed. In this method, the optimal rise time of plunger is set as the target rising time. By analyzing the actual lift time of plunger by the controller, the opening and closing time is automatically adjusted to ensure that the actual lifting time of plunger is close to the rising time of target. The production system of gas well tends to be optimized automatically and the automatic control management of gas recovery process of plunger gas lift and discharge is realized. An integrated plunger controller with better performance is designed. This new plunger drainage and gas recovery technology has been used in 75 wells in a certain block of Changqing gas field. After more than 2 years of practical test, the production system can be automatically optimized and adjusted according to the condition of plunger arrival, and the workload can be greatly reduced. Automatic operation control and fine management of plunger gas lift well are realized. The control method based on the automatic optimization of plunger rising time provides a technical guarantee for the large-scale application of plunger gas lift drainage technology in Changqing gas field.
