岩石地层界面的追踪对比在滚动勘探开发中的实用意义——以辽河西部凹陷西斜坡为例
|
摘要
盆地的勘探都要经历区域普查、区带详探和局部目标区的滚动开发勘探等几个阶段。在地层划分和对比中,早期主要是利用生物地层学、年代地层学、构造地层学、地震地层学、层序地层学和大旋回的岩石地层学方法,建立盆地的地层格架。但到了滚动勘探阶段,油田的勘探成熟度已相当高,钻井、开发资料非常丰富,不论是勘探上的滚动扩边,还是开发上的小层对比,在地层的划分对比中,我们具体研究的就是岩石地层界线。对于存在侧向加积的陆相斜坡沉积,岩相界面与时间界面间的交角可能大于零。但具体到局部区域的滚动勘探开发,这种影响我们不作为重点进行考虑。目前现场实施中,具体操作的就是以研究岩石物理界面的三维空间展布为主要内容的岩石地层界面。
The exploration of sedimentary basins generally undergo stages of reconnaissance survey, detailed investigation and step by step exploration & development, and different methods for sequence correlation, such as biostratigraphy, chronostratigraphy, tectono-stratigraphy, seismic stratigraphy and sequence stratigraphy and so on, can be used. During stage of step by step development of an oilfield, the most important thing is the determination of lithostratigraphic boundary.The stratum boundary of terrestrial sediments on lateral accretion was at all time cross with time definition, but we may ignore its influence. The main point for the study of sequences is the lithostratigraphical boundary and its spatial distribution in the last stage of development.
