Study on the Main Controlling Factors of Tight Oil Accumulation in Carbonate Conglomerate——Taking the Conglomerate Reservoir of the Lower 3rd Member of Shahejie Formation in Shulu Sag as an Example
-
摘要: 通过地震、测井、岩心及分析测试等资料,探讨了碳酸盐质砾岩致密油的成藏特征及主控因素,明确了砾岩致密油的有利勘探方向。结果表明,束鹿凹陷沙三下亚段的砾岩具有陆源和内源混源特征,与砾岩呈互层接触的泥灰岩烃源岩厚度大、分布广、有机质丰度高,为砾岩致密油的成藏提供了物质基础;断层对砾岩致密油成藏的影响有弊有利。优质烃源岩、储层发育程度及有利反向断层圈闭是砾岩致密油成藏的主控因素,成藏模式为“源-储共生”型。建议下一步勘探重点为靠近泥灰岩生烃中心、远离断层发育带并位于坡折带附近的滑塌扇成因砾岩体。Abstract: Based on the seismic data, logging, core analysis and testing, this paper discusses the reservoir forming characteristics,the main controlling factors and favorable exploration direction of the tight oil in carbonate conglomerate.The results show that the conglomerate in the lower 3rd member of Shulu saghas mixed terrigenous and endogenous characteristics.Marl source rocks,interbedded with conglomerate,with large thickness, wide distribution and high organic matter abundance, provide a material basis for the formation of tight conglomerate oil reservoirs.The faults have some effects on the formation of tight conglomerate oil reservoirs.In conclusion, high-quality source rocks,degree of the reservoir developmentand favorable reverse fault traps are the main controlling factors for tight conglomerate oil accumulation.The accumulation mode is "source-reservoir symbiosis".It is suggested that the future exploration should be near the marlite hydrocarbon-generating center and far from the fault development zone,being in the gravel body of slump fan origin near the slope break zone.
