摘要: 前言松辽盆地自从1975年进入隐蔽油气藏勘探阶段以来,对沉积相提出了新的任务,即细分层段研究沉积相和砂体分布模式,这是寻找隐蔽油藏的关键问题。近年来,大庆油田沉积相研究工作主要是根据外围456口探井的岩心资料和分析化验资料,同时充分运用油田近万口密井网的解剖资料,以及参考地震地层学初步成果。Abstract: The Sedimentary features of tie form ation during water progressive stage of the middle-to w er part of the second-class co m pleg depositional cycles in the Cretaceous in Songliao Basin are discussed in this paper. Taking the water progressive delta body formed in Sa.Pu reservoirs of Yaojia Formation for egample,we dissected the strucstures of water progressive delta body of the forty and and backw and sequences and its features of formation.
