摘　　要：比采油指数作为评价储层产能的重要指标,在稠油勘探、开发中具有重要意义。通过总结渤海油田明化镇组、馆陶组稠油储层以往的试油成果,利用灰色关联分析方法分析地化、测井及它们的组合参数与比采油指数的相关性,选取关联度最高的两个参数“测井渗透率/地面50℃原油黏度(K_(m)/μ_(o))”和“孔隙度/重质组分指数(φ/HI)”作为主控因素,通过回归分析建立了比采油指数预测模型,经最新探井试油结果验证,比采油指数预测相对误差率介于5.68%~10.41%。研究结果对区域稠油储层探井测试前的产能预测具有一定指导意义。In heavy oil exploration and development,the specific oil recovery index(Jos)is a critical metric for evaluating reservoir productivity. After summarizing the previous testing results of heavy oil reservoirs in Minghuazhen and Guantao Formations in Bohai Oilfield,the grey relational analysis method was used to analyze the correlation between geochemical,well logging and their combined parameters and the specific oil recovery index, and the two parameters with the highest correlation,“logging permeability/crude oil viscosity at surface 50 ℃(K_(m)/μ_(o))” and “porosity/heavy component index(φ/HI)” were selected to use as the main control factor. And then regression analysis was used to establish a specific oil production index prediction model. The relative error rate of the oil production index prediction was between 5.68% and 10.41%,according to the latest exploratory well test data. The research results have a certain guiding significance for predicting productivity in regional heavy oil reservoirs before exploratory well testing.
