Abstract: The main controlling factors on reservoir's physical properties are the bottleneck in the oilfield development in Baiyingchagan Sag. With respect to the Tengger formation, the major reservoir in the lower cretaceous system, on the basis of the related theory and the method of the reservoir geology, by using core logging, well logging and testing data, the petrological characteristics, the pore types, the pore structure and the physical characteristics are studied, and its main controlling factors are revealed. It is indicated that the reservoir physical properties are obviously controlled by the distribution of sedimentary facies, especially, the microfacies, the high quality reservoirs would distribute along the debouch bar microfacies, the underwater distributary channel microfacies, the sand dam within the fan-delta front and the braided river delta front. Moreover, the diagenetic reformation is the secondary controlling factor for the reservoir physical property of Tengger formation, among which the compaction has an obvious effect to cause a poor physical property, the cementation is responsible for the dualism effect, and the dissolution plays a constructive role. Finally, it is revealed that the high quality reservoir distribution and the favorable sedimentary facies belt distribution are closely related with each other.

Key words： reservoir properties control factors sedimentary facies diagenesis
