摘　　要：河南古城稠油油藏BQ10断块核三段Ⅳ9层为典型的浅层中厚层特-超稠油油藏,采用蒸汽吞吐方式开发。充分利用地质、测井和生产动态等资料,在精细描述油藏基础上,应用Petrel地质建模软件建立油藏精细地质模型。采用CMG软件的STARS模块进行数值模拟,对转蒸汽驱井网及转驱时机和注采参数优选。蒸汽驱应采用70m×100m反九点井网,采注比在1.0—1.2之间,蒸汽干度60%以上为佳。Eh3 Ⅳ9formation in fault block BQ10 of Gucheng heavy oilfield is typically extra-super heavy oil reservoir with medium thick reservoir in shallow, which is exploited by mode of steam stimulation. Based on the fine reservoir description combined with the data of geology, logging and production performance, fine reservoir geological model is set up by means of Petrel and numerical simulation is conducted through STARS module of CMG. It is optimized for well pattern, time and injection-production parameters of steam flooding. Optimization results show that in the period of steam flooding reverse square 9 spot well pattern with the size of 70×100 m2, production injection ratio in the range of 1.0—1.2 and steam quality more than 60% are preferable.
