摘　　要：黄沙坨油田是辽河盆地火山岩储层中首次获得千万吨级规模的油田,是受构造和岩性控制的边底水块状裂缝性粗面岩油藏,由于火山岩储层岩性复杂、变化快,油藏不确定的因素较多,针对这种情况,对黄沙坨油气形成机理和特征进行分析,认为储集层的岩性、结构、构造位置及岩层的厚度是储集层构造裂缝形成的内因,它控制构造裂缝的密度及发育程度,同时在某种程度上也控制了火山岩油藏油层的分布趋势及油层的发育程度。Huangshatuo Oilfield, which is the first oilfield with the scale of tens of millions of tons of oil among volcanic rock reservoirs in Liaohe Basin, belongs to fractured rough surface rock reservoirs in edge--bottom water-- block shape controlled by structure and lithology. Aiming at complex lithology, quick change and uncertain factors of volcanic rock reservoirs, this paper analyzes the forming mechanism and features of oil and gas in Huangshatuo Oilfield and holds that the internal agency of the structural formation of reservoirs is their lithology, structure, structural position and thickness, which control the density and development degree of structural fracture and, to .some extent, control the distribution tendency and development degree of the oil layers of volcanic rock reservoirs.
