摘　　要：运用数值模拟方法 ,采用经济优化原则研究了不同油价下稠油油藏蒸汽吞吐的合理井距。该方法综合考虑了井网密度对稠油热采采收率、油汽比的影响 ,也考虑了井网密度对总投资和各种操作费用的影响 ,确定了不同油价下蒸汽吞吐的开发方式和井网密度。现行油价下 ,齐 4 0块蒸汽吞吐选用 1 0 0 m× 1 4 1 m反九点井网经济效益好 ,建议在开发新区块时 。Reasonable well spacing for steam soak in viscous reservoirs is studied at different oil price by using the numerical simulation in combination with the principle of economic optimization The effect of well spacing density on viscous oil recovery efficiency of thermal production and gas oil ratio is considered comprehensively, and the effect of well spacing density on overall investment and various operational costs is considered as well The development mode and well spacing density of steam soak are determined at different oil price,100 m×141 m inverted nine spot injection pattern is chosen for steam soak in Qi block 40 with good economic benefit It is suggested that when a new block is developed,an inverted nine spot injection pattern for steam soak is used from the beginning
