与构造圈闭相比,岩性圈闭边界条件复杂,形态不规则,赋存状态隐蔽,成藏条件复杂,油气运聚机理多样,给油气藏勘探提出了更高要求。由于岩性圈闭本身形成地质背景的特殊性,决定了岩性圈闭往往以圈闭群的形式出现,单个岩性油气藏虽然储量规模较小,但成群出现的岩性油气藏整体储量规模可观。为了促进岩性油气藏勘探有序、高效、快速的展开,岩性油气藏勘探应遵循滚动预测―滚动评价―滚动勘探的思路和部署原则,同时应根据实际地质条件,配套具有针对性的地质和地球物理勘探技术。

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.
