Abstract: In recent years,with further exploration and exploitation of complicated fracture type oil reservoir in Qingxi Oilfield,a higher requirement is posed to the evaluation of dual-porosity reservoir.The evaluation of fracture pore should not be limited to a qualitative evaluation but extend to a quantitative one.In this paper,the way of calculating fracture porosity is introduced by processing image logging with the use of the softwares of PoroSpect,FVI,PoroDist and using dual laterolog empirical formula to fulfill quantitative evaluation of double porosity reservoir,specific to the lower Cretaceous fracture type reservoir.This way has been applied in fracture type reservoir in Qingxi Oilfield and good application effect is realized.

Key words: fracture porosity, image logging, PoroSpect, PoroDist, dual laterolog
