【摘要】 马东油田为北大港油田港东开发区深层油田,目前已处在产量下降阶段。根据研究区地震、测井和岩心资料,应用高分辨率层序地层学原理,对区内板2、板3油组地层进行了多级次基准面旋回的识别和对比,将其分为1个长期基准面旋回、2个中期基准面旋回和10个短期基准面旋回;分析了基准面旋回对沉积特征、储层物性的控制作用,基准面下降后期、上升早期容易发育良好储层;基准面下降早期、上升后期,储层物性差。更多还原

【Abstract】 As a deep oilfield,Madong Oilfield belonging to Beidagang Oilfield is at the stage of descending.On the foundation of the Seismic data,logging data and core material,the authors identified and compared base level cycles for layer BⅡ and BⅢ according to the principle of high-resolution sequence stratigraphy.Higher baselevel cycles were recognized as an long baselevel cycle,two intermediate baselevel cycles and 10 short baselevel cycles.It was analyzed that the baselevel cycles could control the sedimentary characteristics and the reservoir properties.The sand body descending at the late stage of baselevel-dropping and early stage of baselevel-rising often has well properties.While the sand body descending at the early stage of baselevel-dropping and late stage of baselevel-rising usually has bad properties.更多还原
