利用三维三相黑油模型，在充分进行历史拟合的基础上，分析了轮南油田轮２井区三迭系Ⅱ、Ⅲ油组开发状况；并对合采与分采、衰竭开采与注水开发及不同采油速度等情况下两个油组的产量贡献、含水率、压力、边底水活动规律等进行了深入研究。研究表明：Ⅱ、Ⅲ油组天然水驱能量相差悬殊，属于不同压力系统，且原油饱和压力差异很大，合采时产生严重的层间干扰，两个油组产能得不到合理利用；实行分采分注，开发效果好；该油藏可采用较高速度开采，但采油速度不宜超过３％。
Based on the full historical matching, the development status of Triassic Ⅱ, Ⅲ oil group in Lun 2 well area of Lunnan Oilfield was analyzed by using the three-dimensional three-phase black oil model. The co-production and sub-extraction, failure exploitation and water injection Development and different oil production rates and other circumstances, the two oil production output contribution, moisture content, pressure, the law of the edge of the bottom water conduct an in-depth study. The results show that the natural waterflooding energies of Ⅱ and Ⅲ oil reservoirs are quite different and belong to different pressure systems, and the difference of saturation pressure of crude oil is very large. There is serious inter-layer interference in combined production and the utilization of the two oil groups can not be reasonably utilized. Separation of sub-points, the development of good effect; the reservoir can be used at higher rates of mining, but the oil recovery rate should not exceed 3%.
