为明确水淹油藏蒸汽吞吐后提高采收率的可能性,从火驱开发机理入手,开展物理模拟和数值模拟研究,建立强、弱两大类水淹模型,揭示水淹油藏火驱增压排水开发机理,依据产出流体变化规律及火驱燃烧指标等评价参数,建立判别标准,将水淹油藏火驱划分为4个阶段,厘清了水淹油藏火驱开发规律。研究结果表明,水淹稠油油藏火驱具有增压排水、排水时间长、点火时间长、注气需求高、放热量高、产油峰值高、降黏效果好等开发特点。该研究成果在辽河油田锦91块成功实施,火驱受效特征明显。该研究对边底水或水淹稠油油藏高效开发具有技术指导意义。
In order to enhance oil recovery after converting from steam huff and puff in water-flooded heavy oil reservoirs, starting from the development mechanism of fire flooding, the research of physical simulation and numerical simulation were carried out. Two kinds of water-flooded models were established, namely strong and weak water-flooded models, respectively. The development mechanism increasing pressure and displacing water of fire flooding in water-flooded reservoirs was revealed. Establish judgement criterions based on evaluation parameters, such as changing law of fluid produced, firing indicator of fire flooding, etc. The fire flooding of water-flooded reservoirs was divided into four stages, and development law of fire flooding in water-flooded heavy oil reservoir was clarified. The research results show that fire flooding in water-flooded heavy oil reservoir has lots of characteristics, such as pressure increasement, water displacement, long water-displacement time, long firing time, high gas injection demand, high heat release, high peak oil production, and good viscosity reduction effect. The research results were successfully implemented in Jin 91 block in Liaohe Oilfield, and the response of fire flooding was obvious. The research has a technical guiding significance in efficient development of reservoirs with edge-bottom water or water-flooded heavy oil reservoirs.
