从烃源岩、沉积建造条件、裂缝性质、裂缝保存条件等方面分析了泥岩裂缝性油气藏的形成条件，探讨了泥岩裂缝性油气藏的形成机理，分析了泥岩裂缝性油气藏的识别方法；认为烃源主要来自自身体系，沉积建造对油气藏形成有明显控制作用．泥岩裂缝的发育是成藏的关键因素，盐岩封闭对形成这种类型油气藏有着得天独厚的条件；烃源岩内的油气以混相涌流方式顺层向裂缝储集层中富集成藏；泥岩裂缝性油气藏的识别应综合考虑地质、测井、地震和钻井等方面的信息。最后阐述了东濮凹陷文留中央地垒带沙三段泥岩裂缝性油气藏形成的特点及分布规律。 |

The mudstone-fracture reservoir forming conditions are analyzed, its forming mechanism is discussed and the method for recognizing the mudstone-fracture reservoirs are analyzed from the aspects source rocks, deposition construction conditions, fracture property and its preserved conditions. It is considered that the source rocks are mainly from the system itself, the deposition construction has evident constrain for hydrocarbon accumulation, the mudstone fracture growing is the key factor for hydrocarbon accumulation, the sealing of salt rock has the particular condition for the hydrocarbon accumulation, oil and gas in the source rocks are enriched and accumulated along the fracture reservoirs by way of miscible shove, the geologic information, logging information, seismic information and well drilling information shall be integrally considered for the mudstone-fracture reservoirs. Eventually the characteristics and its distribution rules for forming the mudstone-fracture reservoir in Es3 of central Wenliu graben of Dongpu Depression are described. |
