摘要： 砾岩油藏非储集层砂体吸水会造成模拟压力偏高,从而影响了砾岩油藏历史拟合的精度。利用油藏数值模拟手段,通过设置虚拟层及虚拟井技术,计算出了非油层的吸水量,为合理确定单井及区块配注量提供了依据。通过对克拉玛依油田五2西区克下组砾岩油藏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。提出了这类油藏的开发调整方案,并经实施符合率高、效果较好。

Abstract: Abstract:The water-intake of non-reservoir sandbody in conglomerate reservoir tends to give high simulated pressure. This paper solved such problems and estimated the amount of water-intake in non pay zone using technologies of reservoir numerical simulation and setting virtual strata and virtual wells. Based on the results of production history match of district-wide and individual well, geological model and production performance model were corrected, further howing heterogeneity of the reservoir. Recommended adjusting programs are highly fitted to the field situation and good results are obtained.

Key words: conglomerate reservoir, numerical simulation, history match, virtual strata, virtual well, Karamay oilfield
