摘　　要：为了充分利用现有井网高效开发油藏并合理动用薄互层油藏,提出了基于薄互层稠油油藏蒸汽吞吐后转火驱的一种老井网改造方法,设计了在原有蒸汽吞吐井网的基础上适当打新井的井网模式,并设置了2套井网来实现燃烧方向错开的对向火驱开发模式。结果表明,该方法使得油层火驱热量得以充分利用,大大提高了油藏动用程度。To fully utilize the existing well pattern and develop the thin interbedded reservoir efficiently and reasonably, an old well pattern transformation method based on fire flooding after steam stimulation in thin interbedded heavy oil reservoirs was proposed. The well pattern mode of properly drilling new wells on the basis of the original steam stimulation well pattern was designed, and two sets of well patterns were set up to realize the opposite fire flooding development mode with staggered combustion direction. The results demonstrate that this technology can fully utilize the heat of fire flooding in the reservoir and significantly boost the degree of oil reservoir production.
