【摘要】 应用油藏数值模拟技术,对陆梁油田陆9井区白垩系呼图壁河组K1h1-1～K1h3-1油藏进行了全油藏和单井模拟。在建模时对主要生产层位进行了细分层,以较准确地描述油水分布和注采对应关系。通过对全区及各单井主要指标的生产历史拟合,修正了地质模型和生产动态模型,更好地反映了该油藏的非均质性。在此基础上,结合地质油藏工程研究成果,设计了2个分注合采方案来研究薄层边底水油藏的分注合采效果。模拟结果确定方案1效果较好,可使油田获得较高的采出程度。更多还原

【Abstract】 Based on reservoir simulation, the entire reservoir and the single-well of Cretaceous Hutubi River Group K1h1-1～K1h3-11reservoir is simulated in Luliang Oilfield. When modeling, partitions of the main production layers were used to describe a more accurate oil-water distribution and injection-production relationship. And then through matching the main indicators of production history for the entire reservoir and the single-well, the geological model and the production performance model were modified. As a result, it could reflect the reservoir heterogeneity better. On this basis, according to the research of geological reservoir engineering, two projects of separate injection commingled production are set up to analyze the effect of separate injection-commingled production for thin-layered and bottom-water reservoir. Simulation results of Project Ⅰis better than Project Ⅱ.更多还原
