随着油田开发的不断深入,采油系统效率降低现象相当严重,导致单井油气产量下降甚至关井情况时有发生,严重影响了油田的正常生产,本文详细介绍了影响采油井系统效率的原因,并提出应对方法以此满足油田生产需要,推动油田的可持续发展。 With the deepening of oilfield development, the efficiency of oil recovery system is quite serious, resulting in the decline of single well oil and gas production or even the well shut-in situation, seriously affecting the normal production of the oilfield. This paper introduces in detail the reasons that affect the efficiency of oil well system, And put forward coping methods in order to meet the needs of oilfield production and promote the sustainable development of the oilfield.
