【摘要】 充分运用地震资料,可以提高沉积相划分及储层砂体识别的精度和准确性。通过对测井、地震资料的分析,将辛斜164井区沙三中亚段划分成中9、中8、中7、中6、中5、中4、中3、中2、中1等九个沉积期次。参考地震属性分析,将每个准层序的三角洲又分为三角洲平原、三角洲前缘及前三角洲三个亚相,并描述了沙三中亚段的主要储集体性能。根据沉积相、储集体性能与波阻抗研究,提出了有利勘探区。地震资料及地震属性有助于三角洲沉积相及储层的研究。更多还原

【Abstract】 Fully application of seismic data could improve the precision and the accuracy of the division of sedimentary facies and the identification of reservoir sand body.By the means of analysis of well data and seismic facies,the middle third member of Shahejie Formation in Xinxie164 area of eastern Dongying depression could be divided into 9 parasequences:Z9,Z8,Z7,Z6,Z5,Z4,Z3,Z2 and Z1.In the plane,delta of each para-sequences was classified into delta plane,delta front and pro-delta according to seismic attributes.It is considered that the properties of the primary reservoirs in middle third member.Favorable exploration area was pointed out based on the study on sedimentary facies,reservoir characteristics and impedance.Seismic data and its attribute analysis results contribute to the study on sedimentary facjes and reservoir of the delta.更多还原
