摘　　要：从蒸汽吞吐和蒸汽驱采油特点出发,总结了辽河油田曙二区大凌河稠油油藏剩余油形成控制因素和分布模式。确定了五个级次的剩余油分布模式,包括微观级、单井单层级、井间单层级、层间级和平面级。提出了剩余油形成的三大控制因素,包括油藏地质类、油藏工程类和井网部署等。强调了油藏地质条件的关键作用,阐述了各种地质因素对剩余油形成和分布的控制作用。This paper summarized the forming-distributing mode and its controlling factors of the remains in the Dalinhe heavy oil reservoir of the Shu II District in the Liaohe oilfield on the basis of the character of the steam-injecting & pouring and steam flooding. It confirms five classes of remains distributing mode, including micro-class, single-well and singe-layer class, inter-well and single-layer class, inter-layer class and plane class. The paper put forward three important controlling factors of the remains forming, including oil reservoir geology type, oil reservoir project type and well-net array, etc. It emphasized the key-role of the oil reservoir geology condition and expatiated the controlling role of the remains forming and distributing by all geology factor.
