摘要
The present paper deals with the lithology and physical properties of the clastic reservoirs and their controlling factors on the basis of cores and cast thin sections, SEM, X-ray diffractional patterns and vitrinite reflectance. The clastic reservoirs in the Upper Shihezi Formation are made up of low-porosity and low-permeability reservoirs. There a positive correlation between the porosity and permeability. The clastic reservoirs are well connected, and assigned to the porosity-type reservoirs. The porosity type is dominated by secondary intergranular solution openings. The major controlling factors include sedimentary facies, compaction, cementation and dissolution.
