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。
Based on the reservoir numerical simulation technique, the whole reservoirs and single wells were simulated in K1h1-1 ~ K1h3-1 reservoirs of the Cretaceous Hutubihe Formation in Lu 9 oilfield. During the modeling, the main production layers were subdivided to describe the distribution of oil and water and the correspondence between injection and production more accurately. Through the production history fitting of the main indicators of the whole area and each single well, the geological model and the production dynamic model are amended to better reflect the heterogeneity of the reservoir. On the basis of this, combined with the research results of geological reservoir engineering, two schemes were designed to study the effect of injection and combined production of thin-bottom water-margin reservoirs. Simulation results to determine the program 1 is better, can make the oil field to obtain a higher degree of recovery.
