【摘要】 合理井网形式的部署将会使区块发挥最佳的开发潜能。以辽河油区某中深层块状稠油油藏为例,通过油藏工程与数值模拟相结合的方法,针对性研究稠油油藏水平井蒸汽驱合理井网形式,在实际区块考虑直井和水平井组合形式进行部署,对比优化设计出最优的井网形式。研究结果表明,稠油油藏水平井蒸汽驱合理井网形式为正对排状水平井注汽水平井生产井网和环状混合井网。该研究为稠油油藏井网形式部署提供了新思路,对类似稠油油藏开发具有重要意义。更多还原

【Abstract】 Rational well pattern can release full development potential of an oilfield.The rational pattern for horizontal well steam flooding has been studied by using reservoir engineering and numerical simulation methods for a medium deep massive heavy oil reservoir in Liaohe Oilfield.The combination of vertical and horizontal wells is considered,and the optimum pattern has been worked out.The result indicates that the rational pattern for horizontal well steam flooding in heavy reservoirs shall be row well pattern and circular well pattern.This study puts forward a new thought for heavy oil well pattern arrangement and has important significance to similar reservoir development.更多还原
