摘　　要：系统采集突泉盆地、乌兰盖盆地的地层岩石物性标本,测试了密度、磁化率、剩磁及电阻率。研究发现,由于含油气盆地勘探目标层往往含泥质、炭质成分较多,采用常规的物性标本测试方法很难获得这类地层岩石真实的物性参数,特别是电性参数。通过井旁测井模型与岩心及测井曲线对比,证明井旁测深技术是一种获取地层电性参数的有效方法。结合前人物性研究资料与本次工作结果,系统地整理了突泉盆地、乌兰盖盆地地层岩石物性参数,建立了主要地层-物性柱,分析了盆地的地层岩石物性特征,为在该地区开展非震地球物理测量提供了基础性资料。Through collecting specimens and testing the density,magnetic susceptibility,residual magnetism and resistivity of rocks,the authors found that,during the evaluation of hydrocarbon resources in the oil-gas bearing basin,the real rock physical properties of the exploration targets,especially the electrical parameters,can hardly be obtained by testing specimens conventionally,because the rocks contain too much mudstone and carbonaceous matters.A comparison of the near-well logging model with core and logging curve shows that the near-well sounding technology is an effective method for obtaining the real resistivity value.In combination with physical properties data available,the physical properties of strata and rocks in Wulangai basin and Tuquan basin were arranged statistically,and the histogram of the main strata and physical properties of the study area was established.In addition,the petrophysical characteristics of strata and rocks in the basins were analyzed.The results can provide the basic information for non-seismic geophysical measurements in this area.
