摘　　要：总结海拉尔盆地1996年以来的探井随钻热解分析资料,结合试油数据,将储集层热解参数与原油物性及油层产能参数结合,提出动态产能指数和静态产能指数的概念及计算方法,建立了轻质油层原油性质和储集层产液性质的热解定量判别方法。应用该方法能够及时发现并准确定量评价轻质油层,为确定试油方案提供可靠的依据。应用该方法评价近3年海拉尔盆地贝尔凹陷所有探井的产液性质,符合率由60%左右提高到95%以上,产能预测也取得较好效果。The summarization of the pyrolysis data acquired with drilling in Hailaer Basin, and with the well testing data since 1996, and connected with pyrolysis parameters and crude oil properties and dynamic productivity indexes could be able to set up a pyrolysis quantitative evaluation method about crude oil properties in light crude oil-producing formation and properties of fluid producing layer in reservoirs. By using this method, light oil layers could be found in time and evaluated quantitatively, and believable planning could be proposed for oil test. The coincidence rate for evaluating the properties of fluid producing layer has increased from about 60% to more than 95% nowadays. The application of the productivity prediction method has also gained better effect.
