摘要
针对小断块或井场开采条件受限的薄层稠油油藏,提出水平井分段蒸汽驱的开发方式。因蒸汽驱对油藏条件要求高,故投产前须进行筛选。根据不同原油粘度和油层厚度的组合模拟计算结果,研究原油粘度和油层厚度对稠油油藏水平井分段注采开发效果的影响,建立筛选评价标准。研究结果表明,当油层有效厚度超过7.2m时,可利用水平井分段蒸汽驱经济开采原油粘度低于5000mPa.s的普通稠油油藏;油层有效厚度达9.6m时,该技术可用于开采原油粘度低于20000mPa.s的稠油油藏。
This paper presents a new development scheme of separated injection and production in horizontal well for small block reservoirs or restricted thin-bedded heavy oil reservoirs by production conditions.As team-flooding should be taken under suitable reservoir conditions,it then researches on the effect of oil viscosity and reservoir thickness on separated injection and production in horizontal well for heavy oil reservoirs according to the numerical simulation and establishes the assessment and screening cri...
