“煤层气井排采装备与工艺”实验教学平台研究
|
摘要
应非常规油气排采技术实验教学的需要,针对学生难以理解和区分煤层气排采与常规油气排采设备与工艺的差异性问题,研制了煤层气井排水采气实验教学平台。采用该平台进行综合实验教学,利于学生掌握抽水机与排采泵的工作原理和结构组成、排采冲次的调节方法和实现方式、固-液-气多相流对排采效能的影响,进而强化对煤层气井杆管环空排水-管套环空出气的工作原理和生产工艺的认知,从系统的角度加深对非常规油气排采设备的理解,提高了实验教学效果和学生的工程应用能力。
Motivated by the experimental teaching of unconventional oil and gas drainage system, a set of CBM wells drainage experiment teaching platform has been developed, aiming at the problem that students usually felt puzzled to understand and distinguish the difference between CBM drainage and conventional oil and gas drainage. Adopting the platform in the comprehensive experimental teaching, it can benefit the students mastering the working principle and structure of pumping unit and rod pump, adjustment and implementation method of back and forth frequency, solid-liquid-gas multiphase flow's influence on drainage system. And then, it could strengthen the comprehension of the working principle and technique about the water draining through rod-pipe hohlraum and gas exhausting through pipe-drive pipe hohlraum, strengthening the systemically comprehension to the unconventional drainage equipment and improving the teaching efficiency and students' engineering application ability.
