摘要: 蒸汽驱是提高稠油油藏采收率的一种重要方法,也是一项投资较大的系统工程。在实施蒸汽驱开发前,对油藏进行适用性筛选评价可提高蒸汽驱的成功率和经济效益,有效避免投资风险。基于国内外稠油油藏蒸汽驱筛选标准,综合选择了10个油藏参数作为蒸汽驱筛选的评价指标,利用隶属函数将参数量化,引入加权模糊评判运算模型,建立了简便的蒸汽驱模糊综合评判模型。评判模型对蒸汽驱筛选进行了量化判断,所需参数容易获取,计算速度快、结果精度高。实例证明了该方法的可行性和科学综合性,它克服了筛选标准单因素界限的评价缺陷,可广泛应用于稠油油藏的蒸汽驱筛选。

Abstract: Steam flooding significantly improves the heavy oil reservoirs recovery, however, it is also a costy system engineering. Before carring out steam flooding to develop reservoir, sorting steam flooding applicability can increase the success and economic benefit, and can effectively avoid investment risk. Based on the reviewed steam flooding sorting criteria, ten reservoir parameters have been selected as evaluation index which can be quantified by the according membership function, the simple fuzzy comprehensive evaluation model of steam flooding sorting has been built with introduction of weight fuzzy evaluation computational model. The case history shows the feasibility and comprehensiveness of this method. The model overcomes the shortcoming of the single element limitation evaluation of sorting criteria and can be widely used in the steam flooding sorting of heavy oil reservoir.

Key words: steam flooding, fuzzy comprehensive evaluation, sorting, weighing, degree of membership
