Abstract：Based on the idealized microtectonic model, the curvature of the upper surface of the formation was calculated, which was applied to research the distribution and forecast of frac-tures in the igneous reservoirs. Taking the intrusive igneous rock in shallow layer in the middle of the third member of Shahejie formation in Shang 741 area of the Shanghe oilfield, Huimin sag, Bohai Bay basin for an example, an improved method was proposed, which used the varia-bility value of curvature to replace the absolute value of curvature of the intrusive igneous rock. The results show that the application of this method in the Shang 741 well area is well. The correlatability of the variability value of curvature and distribution of fracture was analyzed by the fracture-areal parameter, and the correlation factor is above 0.79.
