- 摘要:
油气井零散天然气放空不仅浪费能源,还污染环境;现有天然气回收技术较为复杂,投资及运行成本较高,迫切需要一种低成本零散天然气回收技术。提出一种直接压缩拉运回收技术,并从系统设计、创新水合物防控技术论证了其经济可行性。基于全局技术经济优化,确定了不同气量下关键设备的最佳设计参数;创新提出了一种低成本的交替式水合物防控策略,可代替20 kW以上的电加热器或加注3%以上甲醇等常规水合物防控方法;气量为6 000 m3/d时静态回收期仅 3年,经济效益较好。针对产气量较低、距处理站较远的油气井提出了直接压缩拉运回收技术,经济可行性优良,具有较高的社会价值。
The scattered venting of natural gas from oil and gas wells not only wastes energy but also pollutes the environment. Existing natural gas recovery technologies are relatively complex in process and entail high investment and operating costs. There is an urgent need for a low-cost scattered natural gas recovery technology. A direct compression and transportation recovery technology is proposed, and its technical and economic feasibility is demonstrated through system design, innovative hydrate prevention and control technology. Based on global techno-economic optimization, the optimal design parameters of key equipment for different gas volumes were determined. An innovative low-cost alternating hydrate prevention and control strategy was developed, which can replace conventional methods such as electric heaters rated over 20 kW or addition of more than 3% methanol. The static recovery period is only 3 years when the gas volume is 6 000 m3/d, indicating favorable economic benefits. A direct compression and transportation recovery technology is proposed for oil and gas wells with low gas production and long distances to the processing station. This technology demonstrates excellent technical and economic feasibility and holds significant social value.
