摘　　要：针对HQ地区长6储层受多期沉积、成岩作用及构造等因素控制,影响储层渗流和产能的因素较多的情况,提出了一种基于储层常规测井资料预测试油产能的分析方法。依据达西产能预测基本方程,并结合油田区块地质特征和生产状况,选取储层自然电位、自然伽马、井径、密度、声波时差、俄罗斯阵列感应、双感应和微电极电阻率为该区油气储层试油产能评价参数,将目的层段储层划分为高、中、低三种产能类型,建立了储层试油产能预测的测井评价指标体系。采用灰色多元加权评价处理方法,对该区26口井31个试油层段进行了试油产能检验。检验结果表明,21口井26个试油产能层段预测评价结果与试油产能结果吻合,试油产能预测符合率达到83.9%;采用该方法克服了单一或局部参数值不能准确表征储层渗流及其产能的缺陷,有效提升了低渗储层产能预测的定量分析及评价能力。The reservoir of Chang 6 in HQ area is influenced by muhiphase sedimentation,diagenesis and structure.Because of a lot of factors affecting seepage and productivity ,an analytic method for oil testing productivity prediction based on conventional logging is put forward.Based on principal equation of Darcy production prediction ,evaluation parameters of oil testing productivity for the reservoirs of this area are selected ：SP, GR, CL,DEN,AC,Russia array induction,DIL and microelectrical resistivity according to the geological features and production situation of this area.The results of evaluation in testing for oil productivity can be divided into three classes：the high,mid and low.An index system of logging evaluation in testing for oil productivity is established.Grey multiple weighted evaluation processing method is applied for oil testing productivity prediction in 31 layers among 26 wells.The coincide rate reached 83.9% with the same evaluation results and actual result in 26 layers among 21 wells.It can overcome the mistakes resulting from the single or local parameter can＇t characterize seepage and productivity accurately,meanwhile,it promotes the ability of quantitative analysis and evaluation for productivity prediction in the low permeability reservoirs.
