摘要: 辽河油田稠油油藏具有埋藏深、油品类型多等特点,为探索稠油油藏注蒸汽开采后期的有效接替技术,通过开展室内物理模拟和现场试验,研究了注蒸汽开发后火驱开发中深层—特深层层状、厚层块状、水淹稠油油藏以及浅层低渗透稠油油藏等不同油藏类型的可行性,形成了针对不同类型油藏的火驱储层描述技术、室内物理模拟实验技术、油藏工程设计技术、采油工艺技术、开发效果评价技术等,火驱开发油藏的采出程度大大提高,有效缓解了产量递减。该文论述了辽河油田火驱技术探索历程,对不同类型油藏火驱开发配套技术进行了系统总结。研究成果可为辽河油田及同类型稠油油藏火驱开发提供借鉴。

Abstract: Heavy oil reservoirs in Liaohe Oilfield have the characteristics of deep burial depth and multiple oil types. In order to explore the effective replacement technology in the later stage of steam injection in heavy oil reservoirs, through indoor physical simulation and field tests, the feasibility of fire flooding after stem flooding was discussed in different types of reservoirs, such as middle to deep or extra deep layered reservoir, thick massive reservoir, water-flooded heavy oil reservoir, and shallow low-permeability heavy oil reservoir. A series of technologies aiming at different types of reservoirs was formed, which include reservoir description technology for fire flooding, indoor physical simulation technology, reservoir engineering design technology, oil production technology, development effect evaluation technology, etc. The recovery degree of the reservoirs after fire flooding had been greatly improved, effectively alleviating the decline in production. The paper discussed the exploration history of fire flooding technology in Liaohe Oilfield, and systematically summarized the supporting technologies of fire flooding for developing different types of oil reservoirs. The research results can provide a reference for the fire flooding development of Liaohe Oilfield and for the similar heavy oil reservoirs.
