众所周知,水平井在开掘的时候往往因为水平段的压降与采出的程度不均匀,最终使得水边或者底水窜,在这种情况下就直接导致油井含水上升的速度明显加快,最终导致油井才产量局促下滑。考虑到此种技术的要求,本文对中心管采油的技术实施全面的分析与探讨,于水平井的水平段放入一个直径不大的生产管,利用控制好水平井的生产压差,以此来再次调整产液剖面。不仅如此,本文还借助定压模拟选取了中心管的信息与数据,并在某油田实施了现场试验,通过上述方法使得油井的含水率减少了2.2%,日产油提升了3.1吨,从中获得了非常好的控水稳油作用。所以,研究的最终结果显示本文所提出的方法对于调整水平段流入剖面有着非常好的效果,为很多油田水平井的稳定生产提供了科学合理的保障。
As we all know, horizontal wells are often digging because of the horizontal section of the pressure drop and the degree of production is not uniform, eventually making the water or bottom water channeling, in this case, led directly to the rate of oil well water rose significantly, eventually leading to Oil production was clumsy decline. Taking into account the requirements of this technology, this paper analyzes and discusses the technology of central pipe production in a comprehensive way, puts a production pipe with small diameter in the horizontal section of the horizontal well and controls the production pressure difference of the horizontal well To adjust the liquid production profile again. Not only this, but also with the help of constant pressure simulation, the information and data of the central pipe were selected and the field test was carried out in a certain oilfield. Through this method, the water cut of the oil well was reduced by 2.2% and the daily output of oil was increased by 3.1 tons Very good water control oil effect. Therefore, the final result of the study shows that the method proposed in this paper has a very good effect on adjusting the inflow profile of the horizontal section and provides a scientific and reasonable guarantee for the stable production of horizontal wells in many oilfields.
