典型浅水三角洲成因对比与沉积模式——以大庆长垣萨尔图油层为例
|
摘要
通过对大庆长垣统层对比发现,各区块间存在着对比界限不统一问题,原因是对浅水三角洲地层沉积成因认识不清,造成了区块间沉积相带图无法衔接,储层得不到合理分类评价。以该区块萨尔图油层(S)为例,通过密井网资料进行浅水三角洲整体解剖,研究该沉积类型成因对比方法,完善其沉积模式。在地层发育模式方面,分沉积单元级、沉积单元内,采用高分辨率层序地层学分析方法将例层SⅡ3单元沉积演化划分为可追溯的6个时期,明确其沉积成因,指导成因对比;在浅水三角洲沉积模式方面,通过多个单元的精细解剖,分经典的3个亚相带类型和4种特殊沉积区域完善浅水三角洲沉积模式,指导储层的合理预测,加深了对陆相浅水三角洲的认识程度。
It was found out by contrast of Changyuan Reservoir in Daqing Oilfield that there existed the problem of non-unified contrast limitation between each block,the reason was that the genesis of shallow delta sediment was not clearly understood,thus the sedimentary facies-belt chart between the blocks was hard to be connected,the reservoirs there could not be evaluated rationally based on the classification.By taking Sa'ertu Reservoir in the area for example,the shallow water delta was analyzed integrally by using the dense well pattern data,and the method for contrasting the sedimentary genetic type was studied for perfecting the sedimentary mode.In allusion to the stratigraphic development mode,the grade of sedimentary unit and the inside of sedimentary unit,the method of high resolution sequence stratigraphic analysis is used for dividing the SⅡ3sedimentary evolution into 6 traceable stages,its genesis is clarified for guiding the genesis contrasting.For the shallow water delta sedimentary mode,it is perfected by analyzing the fine units based on 3 subfacies types and 4 special sedimentary areas.The method is used for guiding the rational reservoir prediction and deepening the understanding of continental shallow water delta.
