摘　　要：克拉玛依油田八区下乌尔禾组油藏为低渗透厚层砾岩油藏,试井解释模型复杂且多样化,单一的常规达西渗流机理下试井分析模型,不能完全适应试井资料分析解释的要求,本文通过对油藏流体渗流机理的分析和研究,建立了新的试井解释模型———低渗透非达西渗流模型,提高了试井资料解释结果的可靠性,解释结果更加符合油藏实际;同时建立了油藏合理的压力恢复关井测试时间,为同类油藏的试井动态监测提供了可借鉴的经验。The BaQuXiaWuHe reserivior in Kalamay oil-field belongs to low permeability thick conglomerate reservoir, which has complicated and various welltest interpretation modle.But the single Darcy flow welltest modle couldn't meet the need in welltest data interpretation.This article has founded a new welltest interpretation modle——the non-Darcy flow welltest modle by analyzing and studying the reserivior flow mechanism so as to improve the dependability of outcome in welltest data interpretation and it accords to the reserivior fact better.At the same time,the reasonable pressure buildup test period has been ascertained, in order to provide reference experience for welltesting in the same type reserivior.
