利用井震资料预测碳酸盐岩储集层
|
摘要
碳酸盐岩储集层缝洞发育、非均质性强,储层横向预测需要综合测井、地震和试油等资料。利用声电成像测井新技术及资料(特别是电成像、偶极横波等新技术资料)能够精细描述井周储层缝洞发育程度和裂缝走向;沿主裂缝走向作地震剖面寻找异常储集体(俗称"串珠")是目前物探解释的亮点,平面地震波均方根振幅和沿层相干属性切片能够预测岩溶带横向展布。这种测井和地震(井震)资料相结合,储层横向预测技术应用到D号圈闭碳酸盐岩储层初见成效。
Because the carbonate reservoir is of serious heterogeneity and development fracture-cave deposit,predicting reservoir distribution usually requires synthesis of multi-subject such as well logging,seismic,and well testing.Well logging information especially electric imaging and dipole shear wave imaging can only describe fracture striking in the limitations around the wellbore.Using seismic profile along the main fracture strike direction to research particular reservoir is an significant technology now.Root-mean-square amplitude and coherent events along the horizon become an important method to predict distribution of the karst zone.It was achieved good effects by using method of reservoir lateral prediction.
