摘　　要：压裂是油气藏增产改造的重要技术措施,为保证压裂措施效果需要量化选井选层标准、优选压裂井油层参数。以朝阳沟油田某区块为例,将压后日增油量作为压裂效果评价标准,进行压裂井层参数研究。首先利用灰色关联法筛选主要影响因素,结合数学统计分析法,初步确定理想压裂井层参数范围;然后利用模糊综合分析和层次分析方法确定出高评价参照井,进而修正理想压裂井层的参数范围,并以此作为压裂选井选层的标准。应用结果表明,方法简便、准确度高,对油田压裂选井选层工作具有一定的指导意义和应用价值。Fracturing is one of an important measures of petroleum reservoir stimulation. In order to ensure the effects of the measurement, it is required to quantitatively select the standards of the well-layers and optimally choose the parameters of the candidate fractured oil producers. Taking a certain block of Chaoyanggou Oilfield as an example, the daily incremental oil production is regarded as the evaluating standard of the fractured results and moreover the fracturing parameters are conducted for the wells and layers. Firstly screening the main influencing factors by grey correlation method and combined with the mathematical statistics analyzing method to generally determine the ideal fracturing parameter ranges of those well-layers; and then using fuzzy comprehensive analysis and analytic hierarchy process methods to confirm the high-evaluation reference wells, furthermore revise the ideal fracturing parameter ranges as the selecting criteria for the candidate fractured well-layers. The application shows that the method is simple, convenient, accurate and has a certain guiding significance and application value to the selection of the wells and layers in the fracturing.
