中高渗强边水油藏合理采液强度研究
|
摘要
D油田是一边底水发育、处于中含水采油期的中高孔、中高渗透率、强边水油藏。对于此类油藏,开发中主要存在的矛盾是:既要保证油田高速高效开发,又要控制边水过快、过早上升。在实际生产过程中,D油田单井、区块液量与含水相关性很强,这说明该油田存在一个最佳的采液强度。针对上述问题,本文通过对构造位置与含水上升速度的关系、含水上升率与采液强度的关系等研究,确定了D油田合理采液强度,有效控制了单井的含水上升速度,提高了断块的开发效果,并为同类油藏开发提供经验。
D oilfield is a high strong edge water reservoir.For this kind of reservoir, the main contradiction is controlling the water cut, on the one hand is ensuring the production, and on the other hand is controlling the water cut. In actual production, we found that there had a strong correlation between liquid and water content. In the middle water period, when the intensity of the mining fluid is increased, the water content of the single well increases obviously.This indicates that there is a reasonable mining strength.In view of this problem,this paper elaborates.The more important is the knowledge of other fields.
