摘要
Abstract
Oil enrichment degree varies greatly in different parts of Wangquze area of Ordos Basin, which is mainly affected by the reservoir.Therefore, it is necessary to define the reservoir's characteristics and control factors in this area to guide the oil exploration.Based on the data of rock casting thin section, scanning electron microscope, mercury injection and physical properties, this paper studied the physical characteristics of Yan9 reservoir in Wangquzhe, and analyzed the factors influencing the physical characteristics of Yan9 reservoir from various angles.The results show that the reservoir of Yan9 in the study area is mainly composed of medium-grained feldspar lithic sandstone, the interstitial fillings are mainly kaolinite and siliceous, and the storage space is mainly composed of residual intergranular pores and dissolution holes.The connectivity is fine, belongs to the fine connective type;The reservoir is a low porosity and low permeability reservoir with poor physical properties and good pore sorting connectivity.The main factors influencing reservoir physical properties are clastic particle mineral composition, clastic particle size, sedimentary microfacies and diagenesis (compaction, cementation and dissolution).关键词
