目前的估計表明,成熟油田預(yù)計產(chǎn)量下降,可能在世界各地造成碳氫化合物供需之間的差距。盡管非常規(guī)油氣儲量巨大,但它們需要高能量和高能量才能開采石油,而新油田的開發(fā)變得復(fù)雜和昂貴。因此,人們越來越有興趣開發(fā)高效和有效的改進石油采收方法,以提高老化資源的采收率。本研究采用商業(yè)日食軟件對三種IOR(注水,填充井和聚合物驅(qū))模擬對比方法進行了討論。主要目標是比較它們在回收率和凈現(xiàn)值方面的表現(xiàn)。這種方法是使用由Uni CIPR綜合石油研究中心首席研究員?ystein pettersen提供的油藏模擬樣本數(shù)據(jù)的案例研。由于低滲透巖石和壓力下降,該案例是一個油田遇到石油生產(chǎn)困難。為了解決這個問題,第一種方法是修改井筒中的局部儲層壓力(WBHP)。盡管石油采收率有所提高,但研究目標尚未完成。水被注入水庫維持壓力。結(jié)果輕微增加了石油產(chǎn)量。由于分配壓力問題,儲層的某些區(qū)域仍然會出現(xiàn)枯竭情況。然后進行網(wǎng)格細化研究,并在每個區(qū)域進行深入觀察。此外,還增加了三家新的石油生產(chǎn)商(OP2,OP3和OP4)和兩臺新的注水器(WI2和WI3)。隨著油井生產(chǎn)商和井注入量的增加,壓力趨于穩(wěn)定,石油產(chǎn)量增加。最后,使用聚合物驅(qū)油...
