摘要
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.
