Abstract: By an intigration of the data from thin sections, X- diffraction, Scanning Electrical Micro-scope, the author of this paper discussed in detail on the evolution of porosity and diagenesis of Middle Jurassic Reservoir in Tuha Basin, it is indicated that stong compaction is the basic origin of low porosity and low permeabity reservoir. The cementation is controlled by the permeating-diffusing mechanism and the heat convertion mechanism and be able to result in the formation of diagenic trap.

Key words: Reservoir, Diagenesis, Pore evolution, Diagenetic trap
