| 1. | Development of anti - gas subsurface pump started compulsively with magnetic force
磁力强制开启防气泵的研制 |
| 2. | The university of petroleum ( beijing ) thereby develops a simulation test device for hydraulic subsurface pump for gas and liquid two - phase flow
石油大学(北京)为此研制了一套气液两相流液压抽油泵模拟试验装置。 |
| 3. | The investigation in the flow field particularly the miscible - phase flow field in a subsurface pump is the key to improvement of the performance of the pump
研究泵内流场尤其是混相流流场，是改善抽油泵性能的关键所在。 |
| 4. | Besides , it is suggested that the diagnosis and analysis technique of the working conditions of the subsurface pump be further developed and improved to ensure the effective and reliable operation of oil pumping equipment
此外，建议进一步发展和完善玻璃钢抽油杆柱超深抽采油的井下泵工况诊断与分析技术，确保抽油设备高效可靠地运行。 |
| 5. | The device consists of a single - phase flow test device , which can make a real simulation of the downhole working conditions and the flow of the liquid in the subsurface pump , and a miscible - phase flow test device , which can simulate various oil - gas ratios
这种装置由单相流试验装置和混相流试验装置构成，前者能比较真实地模拟井下的各种工况和抽油泵内液体的流动状态，后者可模拟不同的油气比。 |
| 6. | The new unit adopts hollow sucker rod working with pump and as fluid passage instead of conventional sucker rod , and uses a new hanger to fix the one - piece barrel rod pump on the casing wall , improving the operation stability of the subsurface pump
针对这种情况，大港油田新世纪机械制造有限公司研制成功一种新型无油管采油装置，这种装置以空心抽油杆代替实心抽油杆带泵工作并兼作出油流道，还通过一种新型悬挂器将整筒抽油泵固定在套管壁上，提高了抽油泵的工作稳定性。 |
