【摘要】：为实现对地处偏远山区的煤层气田生产排采井的精细化控制,需要突破人工巡井或布设井场间网络的传统方法,通过低成本的技术实现排采数据采集、传输。根据工业无人机体积小、机动灵活、地理适应性强等优点,提出无人机搭载对地数据通信模块、通过通信软件与飞控软件协同工作、依井位地理位置和高程优化飞行航迹与飞行速度,在已投入商业化生产数年的煤层气田进行了工业化数据传输应用实践。结果表明:目前可以实现24 h连续数据读取后的现场存储、一次性传输,数据连续性比原传统人工巡井方式提高数十倍;使用原来人工巡井10%的车辆和人员、原单班65%的巡井时间和原单班50%的井场巡井里程即可完成原巡井抄表任务,实现了煤层气田生产的降本增效。
[Abstract]:In order to realize the fine control of production drainage wells in coal seam gas fields located in remote mountainous areas, it is necessary to break through the traditional method of manual well patrol or lay out the network between wells, and realize the data collection and transmission of displacement production by low cost technology. According to the advantages of small size, flexible mobility and strong geographical adaptability of industrial UAV, this paper proposes that UAV carry data communication module to the ground, and work together with flight control software through communication software. According to the location and height of the well, the flight path and speed are optimized, and the application of industrial data transmission in coal seam gas field which has been commercialized for several years has been carried out. The results show that the field storage and one-time transmission of 24-hour continuous data reading can be realized at present, and the continuity of data can be increased by tens of times compared with the traditional manual well-patrolling mode. By using 10% vehicles and personnel of the original manual well survey, 65% of the original single-shift patrol time and 50% of the original single-shift site patrol mileage, the original well survey meter reading task can be completed, and the production of the coal seam gas field can be reduced cost and increased efficiency.
