【摘要】 从烃源、裂缝、沉积建造、裂缝保存条件等方面分析了泥岩裂缝性油气藏的成藏条件,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;烃源岩内的油气在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、地震和钻井等多方面的信息;并阐述了针对泥岩裂缝性储层的特点选择合适的测井系列,以达到识别裂缝性油气藏的目的。更多还原

【Abstract】 For fractured shale reservoirs, the forming conditions and identification methods are analyzed in terms of hydrocarbon sources, fractures, sedimentary structures and fracture preservation conditions, etc.It is generally believed that the hydrocarbon comes from an internal source. In the forming process, the sedimentation structure plays a dominating role, and the development of shale fractures is also a key factor. Finally, the oil and gas in source rocks accumulate in the reservoirs. As for identification of these reservoir, many aspects of information, such as geological, logging, seismic and drilling, etc., should be comprehensively considered, and an appropriate logging series should be selected based on characteristics of the reservoirs.更多还原
