1. Of this toilet advocate material is shaly .

2. Avoidingthe effect of shaly, tuffaceous and oil, this text established the interpretation equation of the tuffaceous sands effective porosity.

3. The characters of heterogeneity widely exist in shaly sand, carbonate and igneous reservoirs.

4. Corresponding to water hearing shaly sands, the CRL phase angel of oil-bearing shaly sands is large. Meanwhile, it increases with the increasing oil saturation .

5. The membrane potential of shaly sand was influenced by the cation exchange capacity, hydrocarbon saturation and concentration difference of the contacted solutions.

6. The slate can be divided into three types: shaly, sandy and phyllitization slate. It was formed by regional metamorphism of fine detritus in continental shelf.

7. Log data may be used for calculating shaly capping beds parameters such as thickness, displacement pressure, total porosity, effective porosity, permeability, sand content(Sentencedict), etc.

8. Firstly, the volcanics and shaly sand were separated with FMI static images and conventional logging data.

9. There is more methane, ethane, isobutane and isopentane in shaly limestone than in marlite.

10. WaxmanSmits (WS) equation is an evolution of Acrhie equation for shaly sands, and it is a nonlinear equation.

11. Based on parallel conductance between laminated shale and dispersed shaly sand, and ABC resistivity model proposed by V. S.

12. Correction accuracy for clean sand and most of the shaly sand is less than 5% and 10% respectively.

13. In the paper , study on conductance mechanism of complex shaly sand reservoirs with bothlaminated shale and dispersed shale is carried out.

14. Log data of well SU-1 and SU-3 in the very shaly formation in Hailaer basin are interpreted with the model proposed in the paper, then the calculated water saturation with test results is compared.

15. This type oil is mainly from the laminar algal shaly dolomite of Xiagou formation that deposited in the reduction environment of Qingxi Depression region.

16. Through the analysis of real geology information, the log interpretation method for the complex shaly sand and the saturation calculation method for the low resistivity reservoir have been discussed.

17. Two-window method is used to modify CPMG pulse sequence, 2D NMR experiments on water-saturated man-made sandstone with moderate paramagnetic impurities and shaly sandstone are measured.

18. Further studies on this project should provide key parameters for interpretation of oil and residual oil saturation of shaly sandstone reservoir bed.

19. Restricted by the conventional interpretation techniques, such as the shaly fine sand and siltstone are usually recognized as mudstone or dry formation.

20. The thesis includes two parts basically, and one model was established in each part for studying permeability of shaly sandstones.
