摘要
稠油油藏是一种重要的战略资源,对保障国家能源安全起到重要的作用。国内外稠油开发主要有蒸汽吞吐、蒸汽驱、驱泄复合(SAGD)、火烧驱油4项技术,受技术适应性、成本高及对环境不友好的影响,其推广和运用存在一定局限性。胜利油田根据自身油藏特点,形成了薄层水平井、热化学复合和化学降黏3项新技术,拓展了开发技术界限,使稠油油藏开发的有效厚度界限低至2m、油藏埋深为2000 m、储层渗透率界限低至100×10^(-3)µm^(2)。根据各项技术特点和矿场应用效果,建立了以技术适应性为基础的稠油新分类标准,把稠油油藏分为5大类,指导矿场稠油开发技术方向的选择。结合目前技术发展方向和新的形势要求,指出“多元热复合”“非热力开发”“纳米材料应用”将是稠油开发技术3个趋势。
Heavy oil reservoirs are crucial strategic resources that play a significant role in ensuring national energy security.The development of heavy oil both domestically and internationally primarily involves four technologies:steam huff and puff,steam flooding,Steam Assisted Gravity Drainage(SAGD)and fire flooding.However,due to issues such as technical adaptability,high costs and environmental concerns,the promotion and application of these technologies face certain limitations.At Shengli Oilfield,three innovative technologies have been developed to overcome these limitations:thin-layer horizontal wells,thermochemical composites and chemical viscosity reduction.These advancements have pushed the boundaries of development technology,reducing the effective thickness limit of heavy oil reservoirs to two meters,the depth limit to 2000 meters,and the permeability limit to 100×10^(-3)μm^(2).Based on the technical characteristics and field application effects,a new classification standard of heavy oil based on technical adaptability has been established.This standard divides heavy oil reservoirs into five categories to guide the selection of development technology at the field level.Looking forward,it is projected that“multi-thermal composites”,“non-thermal development”and“nano-materials”will be the three main trends in heavy oil development technology.
