CLASSIFICATION AND GEOLOGICAL MEANING OF THE FLOW UNIT OF THE CHANG 1 RESERVOIR IN DING 31 WELL AREA OF YOUFANGZHUANG OIL FIELD
油房庄油田定31井区长1油层组流动单元的划分及其地质意义

Through the deposition layering of Chang 1 reservior in Ding 31 well area of Youfangzhuang oil field,in terms of the character parameter of rock physics,adopted the method of direct clustering analysis, A, B, C, D four kinds of flow units are classified in Chang 1 reservior of this area, and the geological meaning of them are. analysised. Study results show,type A has strong percolating and storing ability, high picking degree, low saturation degree of residual oil; type B has rather strong percolating and storing ability,rather high picking degree, it's the main productive formation of research area; type C has commonly percolating and storing ability, rather low picking degree, comparatively high saturation degree of residual oil; type D has poor percolating and storing ability, is a non-produce formation,poor effect of expoitation.
