摘　　要：利用水平井蒸汽吞吐开发薄层、超稠油以及具有边底水等复杂条件的稠油油藏具有较好的优势,但是水平井投资大,风险高,研究水平井蒸汽吞吐经济技术界限十分必要。基于油藏数值模拟和动态经济评价方法,研究了无边底水、边水以及底水3类稠油油藏水平井蒸汽吞吐的油层有效厚度界限、油价边界值以及地面原油粘度界限。"底水稠油油藏含水率上升最快,开发效果最差,因此经济技术界限也最为苛刻。当油价为50美元/bbl时,地面原油粘度为10 000 mPa.s的无边底水、边水以及底水稠油油藏进行水平井蒸汽吞吐开发的油层有效厚度界限分别为2.7,2.9和13.8 m。建立不同油价下的经济技术界限图版以及定量关系式,便于根据油价波动动态地指导不同类型稠油油藏水平井蒸汽吞吐经济开发。mic economic evaluation method,reservoir effective thickness limit,oil price limit and ground crude oil vis-cosity limit of steam soak in horizontal well within three types of reservoirs including reservoir without aquifer,reservoir with edge water and reservoir with bottom water are studied herein.The results show that,the water cut of the heavy oil reservoir with bottom water increases the most sharply,so the development performance is the worst,and economic and technical limit is the most de-manding.When oil price is 50$/barrel and ground crude oil viscosity is 10 000 mPa·s,reservoir effective thickness limit of the reservoir without aquifer,reservoir with edge water and reservoir with bottom water is 2.7,2.9,13.8 m respectively.Through practical charts and the quantitative formulas,different economic and technical limit are derived,and it is convenient to guide dy-namically the development of heavy oil reservoir through steam soak in horizontal well in accordance with oil price fluctuations.
