Abstract: Abstract：How to develop low-permeability reservoirs has become the key question in the field of oil and gas production.
However，the heterogeneity of low-permeability reservoirs is the main factor affecting the oil recovery. Therefore，a reservoir
mechanism model，based on the reservoir geological model presented in this paper，is used to analyze the influence of the
respective and combined elements on oil reservoir recovery，with reservoir thickness，interlayer thickness，permeability and
permeability anisotropy coefficient as evaluation variables. The result reveals that the permeability and permeability anisotropy
coefficient are the two main factors. This research is significant in adjusting and making full use of potentialities in later stage
of oil and gas development.
