姬塬油田胡154井区延长组长4+5储层特征
Charactristics and Influential Factors of Chang 4+5 Reservior in Hu 154 Well Field,Jiyuan Oil Field
摘要
Abstract
Based on core observation, logging data and sample tests, the reservoir petrology, pore structure, physical properties and other reservoir characteristics of Chang 4 + 5 in Hu 154 well area are discussed in this paper. The research demonstrates that the reservoir of Chang 4 + 5 is low porosity-low permeability. The reservoir is lithic feldspathic sandstones and feldspathic lithearenite sandstones with low compositional and textural maturity. The pore space is mainly intergranutar pore and fledspar solution pores. Pore structure is small hole.with microthroat. The reservoirs properties are controlled by interplay of sedimentary and diagenesis. Sedimentary is the first factor showing that the distributary channel depos-ites is the main reservoir sands. Diagenesis alters the physical properties in two opposite aspects. Compaction and cementation reduce the physical properties while dissolution can make it better.关键词
