摘要
从国内典型稠油油藏热采开发实例出发,对影响开发效果的因素进行逻辑分析和相关性分析,优选出10项具有较强分类特征且影响开发效果明显的指标,并根据现场统计数据各指标的变化范围及规律,对指标进行了量化分级。基于模糊综合评判原理和层次分析法建立适用于稠油热采开发效果评价的多因素模糊综合评价模型。对王庄油田的热采区块进行了模糊评价,结果表明,该模型能综合反映多方面的开发因素,可用于指导稠油油藏热采开发效果的正确评价。
Ab Based on the cases of thermal recovery of domestic typical heavy oil reservoirs, the influence factors on the development effects are analyzed in logical relation and correlation, and ten indices are chosen for them. The quantitative grading of these indices is conducted, considering their varied ranges and regularity from field statistics. And then a muhifaetor fuzzy judgment model for thermal recovery effect of heavy oil reservoir is developed by fuzzy judgment theory and analytical hierarchy process. The case study from fuzzy judgment on the thermal recovery blocks in Wangzhuang oilfield shows that this model can reflect multifactor development performance and be used to prop- erly guide the thermal recovery development of these blocks.
