针对大庆油田萨中开发区过渡带地区原油黏度大、含蜡量高、含胶量高,导致油井生产不正常的状况,优选试验井组,在2口井进行注入试验,取得了注入井的注入压力下降,中心井产油上升,含水下降的效果,为将来进行微生物驱奠定了基础。 Aiming at the situation that the crude oil viscosity is high, the wax content is high and the cement content is high in the transitional zone of Sazhong Development Zone in Daqing Oilfield, which leads to the abnormal production of oil well, the pilot well group is selected to conduct the injection test in two wells and the injection well Injecting pressure drop, central well oil production rise, the effect of water cut, lay the foundation for future microbial flooding.
