摘　　要：在薄层底水油藏开发过程中,由于油层下部水体发育,能量充足,极易发生底水锥进现象,从而导致其开发效果变差.双层完井排水采油技术可以抑制底水锥进,达到解放油层生产潜力、改善油藏开发效果的目的.基于其原理并结合陆梁油田陆9井区呼图壁河组K1h23油藏的储集层参数,应用油藏数值模拟技术研究了理想单井模型下隔夹层对排水采油动态的影响.数值模拟结果表明:有效的隔板能够很好地抑制底水锥进,但隔板尺寸大小与排水规模之间有一定的关系.In the development of the thin oil reservoir with bottom water,the phenomenon of bottom water coning easily occurs because of the sufficient energy of the bottom water,which will leads to the bad development result of the thin bottom-water reservoir.The bilayer well completion-water drainage-oil production technology can inhibit the bottom-water coning to tap the productive potential of the reservoir and improve the development result of it.Based on the principle of the technology and the reservoir parameters of K1h23 reservoir of Hutubihe Formation in Lu9 well block of Luliang Oilfield,the influence of the impervious interbeds on the water drainage-oil production performance is researched under the condition of ideal single well model using reservoir numerical simulation technique.The numerical simulation results show that the effective baffle plate can inhibit the bottom water coning,but there is a certain relationship between the size of the baffle plate and the scale of the water drainage.The results in this paper have a reference for the development of similar reservoirs.
