摘    要:在隐蔽油气藏勘探中,储层预测既是关键点又是难点。测井约束反演是隐蔽油气藏储层预测的一种行之有效的方法,通过对测井资料的校正、地震子波的提取、井震标定以及在沉积概念指导下的地质模型的精确建立,从而得到合理的初始阻抗模型,根据已知的地质规律并以钻井、测井资料为约束,预测储层的分布。在大港油田K46井区应用稀疏脉冲反演方法,成功地进行了隐蔽油气藏储层的预测,取得了明显的应用效果。 

关 键 词:约束反演   隐蔽油气藏   储层预测   阻抗模型

Abstract:The prediction of reservoirs is a key point as well a difficult point in exploration for subtle petroleum accumulations.Logging-constrained inversion is an effective method for predicting subtle reservoirs.A rational initial acoustic impedance model was constructed by correcting the log data,extracting seismic wavelets,calibrating downhole seismic records and constructing a precise geological model under the guidance of the sedimentary concept,and the distribution of the reservoir was predicted according to the known geological regularity and by taking the well logs as the constraints.The sparse impulse inversion method was applied in the K46 well area of the Dagang oilfield and a subtle reservoir was successfully predicted there.
Keywords:constrained inversion  subtle petroleum accumulation  reservoir prediction  acoustic impedance model
