摘　　要：原油由轻中重组分组成,每个录井参数代表着某一部分的油气特征信息,同时又不同程度反映了原油总体物性。根据参数相关性大小分析预测结果,地化热解>地化色谱>三维荧光>气测参数。在一定条件的约束下,部分可以反映整体,是单个录井参数可以进行原油物性预测的基础。在响应机理的指导下,以原油物性分析化验数据为刻度,开展了研究区的原油物性定量预测,形成了色谱标定下的热解预测法、限定条件下的气测预测法,预测原油密度的绝对误差分别为±0.01和±0.02。基于强相关性多因素,建立了适合研究区多场景的预测-转换公式集。The crude oil is grouped into light-medium recombination groups.Each logging project represents the characteristics of a portion of the oil,but also reflects the overall physical properties of the oil to varying degrees.According to the correlation size,the prediction effect was analyzed as follows:geochemical pyrolysis>geochemical chromatography>three-dimensionalfluorescence>gas measurement.Under certain conditions,the part can reflect the whole,which is the basis of oil physical property prediction for a single logging project.Under the guidance of internal principle and response mechanism,the quantitative prediction of crude oil physical properties in the study area was carried out with the crude oil physical properties analysis data as the scale,and the pyrolysis prediction method under chromatographic calibration and gas prediction method under limited conditions were formed.The absolute error of predicting crude oil density was±0.01 and±0.02,respectively.Based on the strong correlation and multiple factors,the predictor-transformation formula set suitable for multiple scenarios in the study area is established.
