Abstract:

 Based on the data of thin sections, casting thin sections, scanning electron microscope and core analysis, this paper studied the petrology characteristics, physical properties and influencing factors of lower assemblage reservoir of Yanchang Formation in Dingbian-Ansai area. The result shows that Wuqi and Ansai area are mainly
feldspathic sandstone because the sediment source is single, and the sandstone rock types in Dingbian and Zhidan area diversified by different source rocks and are mainly arkose and lithic arkose. The reservoir space of lower assemblage reservoir of Yanchang Formation mainly includes primary intergranular pores and secondary dissolved pores. The reservoir is characterized by low-ultra-low porosity and low-ultra-low permeability. The reservoir properties are affected by sedimentary microfacies and diagenesis. The reservoir properties in Wuqi and Dingbian area are best, the next is in Zhidan area, and the reservoir properties in Ansai area are poor. In longitudinal, the reservoir properties of Chang 10 are the best, the next is Chang 9, and the reservoir properties of Chang 8 and Chang 7 are poor.

Key words: tight sandstone , effective reservoir , lower limit ofreservoir properties, Ahe Formation , Dibei gas reservoir , TarimBasin
