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。
The hydrocarbon accumulation conditions of shaly fractured reservoirs are analyzed from hydrocarbon sources, fractures, sedimentary structures and fracture preservation conditions, and the identification methods of fractured reservoirs in mudstone are analyzed. The hydrocarbon sources are mainly derived from their own systems, The formation of a clear control role, the development of shale fractures is the key factor for hydrocarbon accumulation; hydrocarbon source rocks within the reservoir in the reservoir accumulation of rich reservoirs, mudstone fractured reservoir identification should be considered geology, logging, earthquakes and drilling, etc. And expounds the selection of suitable logging series for the characteristics of fractured reservoirs in mudstone so as to achieve the purpose of identifying fractured reservoirs.
