浅析油田井筒防气技术的应用

Application of Gas Prevention Technology in Oilfield Shaft

从如今的油田发展抽汲状态来看,对于抽油泵有所影响的主要就是气体。在整个抽油泵抽汲中,在泵中留有游离的气体和溶解的气体等。从气体的上冲过程里,如果在中间存留气体,而且在膨胀起来之后不能做到让原应降低的压力低于吸入泵的压力,此时的固定阀门是不可以打开的,泵中就会生成上冲的气体状态。如果泵的总体压力比油管之中的液柱压力低的时候,游动的阀门是不可以被打开的,这时的泵就会在下冲时发生气锁现象。在这些现象发生的基础上,如果情况较为严重的话,就会在上冲和下冲的过程中都有可能发生气锁。因此在将气体合体抽油井时,就要防止油泵发生气锁,并且提升泵效,这些都需要不断采取各种防气技术策略。从油田井筒的防气技术中考虑对其的应用,并且深入分析气体对于油田井筒的影响,由此可以得出一些井筒防气技术方面的思路。

From today＇s development of the oil field pumping point of view,the main impact on the pump is the gas.In the pumping of the entire pump,leaving the pump in the free gas and dissolved gases.From the gas on the red process,if the gas in the middle,and after expansion can not be done so that the original pressure should be lower than the suction pump pressure,then the fixed valve is not open,the pump will Generate the upper gas state.If the overall pressure of the pump is lower than the pressure in the tubing,the swivel valve can not be opened,and the pump will cause an air lock in the undershoot.On the basis of the occurrence of these phenomena,if the plot is more serious,it will be in the red and under the red in the process are likely to occur air lock.Therefore,when the gas is combined with the oil wells,it is necessary to prevent the oil pump from gas lock,and to enhance the pump efficiency,which require us to continue to take a variety of anti-gas technology strategy.From the oil field wellbore anti-gas technology to consider its application,and in-depth analysis of gas for the oil field wellbore,which can be derived from some wellbore gas control technology ideas.
