摘要
根据区块压裂施工参数及裂缝参数的分布特点,分别建立了隶属度分布函数,然后综合运用概率统计、模糊数学、裂缝模拟及油藏模拟等方法,建立了区块整体压裂开发的模糊不确定性经济评价模型。该模型可对难动用区块整体压裂开发的经济效益进行概率分析,并可判断是否适合压裂开发,从而为该区块判断是否适合压裂、压裂的投资决策及风险性分析提供依据。实例区块分析表明,所建模型及其计算结果是可靠的。
Based on the distribution characteristics of hydraulic fracturing parameters and fractures parameters, two functions are established respectively. After that, an undetermined fuzzy economic evaluation model was created for the overall hydraulic fracturing based on probability statistic, fuzzy mathematics, fracture simulation, and reservoir simulation. This model can statistically analyze the economic benefit for overall hydraulic fracturing in difficulty reservoirs to determine if these reservoirs are fit for hydraulic fracturing. Therefore it will provide basis for economic risk analysis, decision making of fracturing investment. A field case indicates that this model is reliable.
