Abstract:

The characteristics of rock association, reservoir properties, pore structure, diagenesis, seismic response and thickness distribution of Jia 2 reservoir in Shuangmiaochang structure are expounded. It is concluded that Jia 2 reservoir is mainly composed of dolomite, and the reservoir is mainly fracture-pore type with good reservoir properties. The reservoir space is mainly intercrystalline solution pore and fracture. The seismic response characteristic is continuous and parallel medium frequency and middle-high amplitude with 2 or 3 phases. The reservoir thickness is thinner, general of 25 to 40 m.

Key words: reservoir, porosity, gas saturation, reservoir description, Junggar Basin
