The microstructures of oil reservoir refer to occurring structural feature resulted from its own slight changing in overall reservoir structure background.

The study of microstructure in the lowest permeable reservoirs has the instructive action for the development of oilfield.

By the study of microstructure on 12 subzone of Gao104-5 district,we have revealed microstructure character on Gao104-5 district,summarized the microstructure types,analyzed the relationship between microstructure and the production of the oil well.

This paper briefly discusses the genesis mechanism and classification of the micro-structure,and the relationships between the types of microstructures and the oilfield development of Chang 212 layer in Zhang tian qu Oilfield are studied.

In allusion to the characteristics of multi-layer reservoirs at high water-cut stage, based on fine flow unit division, microscopic structures, reservoir sedimentary microfacies, reservoir physical properties and its heterogeneity were studied and a 3D visualization geologic model was established.

Micro structures and reservoir property are the basic factors influencing the distribution of remaining oil;normal micro structures and micro roof type structures are the positions for oil enrichm.
