Abstract

Contrast to structural traps, the lithologic traps are characterized on complexin boundary condition, irregular in shapes, subtle in occurring, complex in accumulation mechanisms and variation in migration. All of these features determined the difficulty of lithologic reservoirs exploration and lithologic reservoirs exploration should abide corresponding exploration tragedy and techniques. Because of the peculiarity of geological background of lithologic traps formation, the lithologic traps are always occurring in state of group. Though a single lithologic trap is small in oil or gas accumulation, a group of lithologic traps are objective in reservoir amount. To the exploration of lithologic reservoirs, the rolling prediction, rolling evaluation and rolling exploration is an effective exploration tragedy and deployment rule, at the same time, practical and effectivegeologic and geophysical exploration techniques must be adopted and matched according concrete geology conditions to promote the developing of lithologic reservoirs exploration effectively.
