| 摘 要： | 克拉玛依油田一中区克拉玛依组S_4~1小层组发育的低弯度曲流河储层为该区块的主要油层之一,目前由于缺乏相对应的精细地质模型,已严重影响了该区块的剩余油分布研究工作。为了解决上述问题,通过对山西省柳林地区二叠系石盒子组低弯度曲流河地质露头实地测量,应用层次分析法和构型要素分析法建立低弯度曲流河露头地质模型。使用该模型并充分利用岩心和测录井资料,对S_4~1小层组沉积时期所发育的低弯度曲流河储层内部构型表征进行了预测,取得了较好的效果。研究表明,露头地质模型不仅对低弯度曲流河沉积模式的建立、单河道的划分,以及井间砂体的对比研究具有重要指导意义,而且能够准确的厘定井下区域单河道砂体及增生体规模、隔层密度、倾角和排列方式等,可为剩余油分布富集规律预测提供理论依据。

| Abstract: | The low-sinuosity meandering river outcrop reservoirs occur as important oil reservoirs in the S41 oil layer of the Karamay Formation in the central part of the first block, Karamay Oil Field, Xinjiang. A geological model for the low-sinuosity meandering river outcrop reservoirs is presented in the present paper on the basis of hierarchical analysis and configuration analysis, and has proven to be available for the prediction of the internal configurations of the low-sinuosity meandering river outcrop reservoirs developed during the deposition of the S41 oil layer of the Karamay Formation. The construction of the outcrop reservoirs model herein is helpful not only to the modeling of low-sinuosity meandering river deposits, division of single channel and comparative study of interwell sandstones, but also to the delineation of the scales of the channel sandstones, density, dip angles and alignment patterns of the interlayers within the single channels, and prediction of distribution and enrichment of residual oil. |
