高气油比油井套压控制对油井产量影响分析

Analysis on the Influence of Casing Pressure Control on Production of Oil Well With High Gas-Oil Ratio

在高气油比油井中,套压的大小对油井采油速度、生产压差、泵效等各个方面具有显著的影响。本文就套压的大小对泵效的影响从气锁形成到井筒压力变化进行了论述,同时介绍了部分常见的防气措施及原理。

In high gas-oil ratio oil wells,the casing pressure has a significant impact on oil production speed,production pressure difference,pump efficiency and other aspects.In this paper,the impact of casing pressure on pump efficiency was discussed from the formation of gas lock to the change of wellbore pressure.And some common gas prevention measures and principles were briefly introduced.
