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。
The Ⅳ9 layer of the third member of BQ10 fault block in the ancient city heavy oil reservoir in Henan Province is a typical middle-thick super-thick super-heavy oil reservoir developed by steam huff and puff. Make full use of geological, logging and production dynamics and other data, based on the fine description of the reservoir, the application of Petrel geological modeling software to establish a reservoir of fine geological model. The STARS module of CMG software was used for numerical simulation, which optimized the timing of steam flooding well and the parameters of injection and extraction. Steam flooding should be used 70m × 100m anti-nine well patterns, mining than in the 1.0-1.2 between the steam dryness of more than 60% is better.
