Abstract：Facing the concrete feature of Mesozoic vulcanite in Youyangou of Liaohe eastern depression,the paper uses the ratio of P-wave velocities[1～3] ——the fractural analysis approach by flexural strength to study the development degree of vulcanite fracture.It is discovered through integrating the fractural analysis approach by flexural strength with other methods that the feature of logging facies in effecfire reservoir of Mesozoic vulcanite of the region mainly shows as low density, low neutron, high interval transit time and high gamma value.The key of the approach lies on selection of appropriate rock framework parameters according to different lithology of vulcanite.The approach uses the logging-constraint seismic inversion to compute the interval velocity of vulcanite on that basis, and further computes the flexural strength;then draws the predicted isopath map of vulcanite based on the feature of logging facies in vulcanite-drilled borehole.
