【摘要】：为指导SAGD开发区油气开发及认识剩余油分布规律,应用高分辨率层序地层学方法,综合岩心、测井及地震资料,研究了辽河坳陷曙一区杜84块SAGD开发区馆陶组冲积扇储层层序分布模式。结果表明:馆陶组地层可划分为1个长期旋回,4个中期旋回及10个短期旋回,其中短期旋回按可容纳空间大小可划分为Ⅰ,Ⅱ,Ⅲ,Ⅳ和Ⅴ型;以中期旋回为等时单元,垂向上等时单元内形成的短期旋回类型与其在中期旋回中的位置有关,而中期旋回的保存程度又取决于其在长期旋回中的位置,侧向上等时单元内形成的短期旋回的可容纳空间顺物源方向逐渐增大。杜84块SAGD开发区馆陶组短期旋回类型与储层物性存在对应关系,较优的储层位置多处于中期基准面上升早中期的冲积扇扇根与扇中交界处或扇中前缘。
[Abstract]:In order to guide the development of oil and gas in SAGD development zone and to understand the distribution law of remaining oil, the high resolution sequence stratigraphy method is used to synthesize core, well logging and seismic data. The stratigraphic sequence distribution model of alluvial fan reservoir of Guantao formation of SAGD development zone in Shu1 area of Liaohe depression is studied. The results show that the strata of Guantao formation can be divided into 1 long term cycle, 4 intermediate cycle and 10 short term cycles, in which the short term cycles can be divided into 鈪，
