在油田开采时间日益增长的影响下,目前油层中的能量已出现消耗殆尽的趋势,也因此降低了油层压力,加上原油粘度在后期的提高,使得油井采油出现产量降低甚至停产的事件。而在采油工程中应用注水工艺,可有效增加油层的压力,并降低原油的粘稠度。基于此,本次研究对采油工程中注水井的现存问题、原因等进行研究,并提出改进注水工艺的几点措施,以促进采油工程的发展。
Due to the increasing exploitation time of the oilfield, the energy in the reservoir has been depleted at present, and the pressure of the reservoir is also reduced. In addition, the viscosity of the crude oil increases in the later period, causing the oil recovery of the oil well to decline or even stop. In the oil production engineering application of water injection process, which can effectively increase the pressure of the reservoir, and reduce the viscosity of crude oil. Based on this, the current research on the existing problems and causes of water injection wells in oil production engineering is studied, and some measures to improve the water injection technology are put forward so as to promote the development of oil recovery engineering.
