【摘要】 主要是对松辽盆地王府断陷泉三段地层沉积特征进行研究,首先在工区内选取标准井进行单井相分析,初步断定沉积相的类型。随后根据全区内所有井的岩心、测井资料对整个工区内的各种沉积微相类型进行判断和分析。通过研究可知泉三段地层为曲流河相,主要发育河床滞留沉积、边滩、天然堤、决口扇、河漫滩和河漫湖泊六种沉积微相。通过地震剖面中对下切谷的识别以及地震属性的提取和分析从而确定平面相的展布特征。更多还原

【Abstract】 Sedimentary characteristics of member 3 of Quantou group in Wangfu area,Songliao basin were studied. At first a standard well was chosen to carry out single well facies analysis, and the type of sedimentary facies was preliminary determined. Then according to core of all wells in the district and logging data of the whole work area, different types of sedimentary microfacies were judged and analyzed. The results show that the member 3 of Quantou group is meandering river facies, it can be further divided into riverbed detainment sedimentation, point bar, natural levee, crevasse splay, alluvial flat and diffuse lake river six kinds of sedimentary microfacies.Through the recognition of incised valley in seismic profile and seismic attribute extraction and analysis, the distribution characteristics of the phase plane was determined.更多还原
