复杂断块等时地层格架建立方法
|
摘要
针对枣园油田断裂系统发育、构造复杂、地层对比困难的情况,依据高分辨率层序地层学理论,将地层学与沉积学有机结合,充分利用岩心、测井及地震资料,识别出4个级别的标志层。采用把电测曲线特征、标志层、沉积旋回及厚度相结合的方法,统一全区的地层划分和地层对比标准,建立了枣园油田枣Ⅳ油层组高分辨率精细等时地层格架,为研究储层空间分布规律奠定了基础。
Considering the complexity of fault system and structural pattern in Zaoyuan Oilfield, as well as the difficulties of stratigraphic correlation, information of core, logging, seismic profile is collected and four classes of marker beds are recognized on the basis of stratigraphy, sedimentology, and high-resolution sequence stratigraphy. By using electrical logging curve-characteristics, marker beds and sedimentary cycle together with thickness to establish the correlation standard of strata in the whole region, high-resolution isochronous stratigraphic framework of Zao-IV reservoir group in Zaoyuan Oilfield has been set up, which laid the foundation for the research of spatial distribution of reservoirs.
