传统的油页岩资源勘查与识别主要依靠野外地质调查、钻井取心及测试分析,测井方法技术在油页岩实际勘探中应用较少,还没有形成一套完整的、可被广泛应用的技术方法。基于大量的文献调研分析,从岩石特征、矿物特征、有机碳含量、成熟度、质量特征等5个方面系统归纳了油页岩的地质特征,分析总结了油页岩常规测井方法技术和测井新方法技术。针对油页岩的地层特点并结合与之类似的烃源岩的特点,从地层矿物组分估算、有机碳含量、有机质类型、有机质成熟度、孔隙度及含油率等6个方面全面论述了油页岩的测井资料解释方法。由于油页岩的裂缝发育程度直接影响其开采效益,而裂缝的有效识别和评价依旧是个难题,故增加了油页岩及油页岩裂缝的定性评价和定量评价方法。虽然此方法还处于发展完善阶段,但对于油页岩的测井评价意义重大。
The traditional exploration and identification of oil shale resources rely mainly on the field geological survey, drilling coring and test analysis, logging method technology is less used in the actual exploration of oil shale, has not yet formed a complete set, can be widely used Technical method. Based on a large number of literature research and analysis, the geological characteristics of oil shale are systematically summarized from five aspects of rock characteristics, mineral characteristics, organic carbon content, maturity, and quality characteristics. The conventional oil shale logging methods and techniques are summarized and analyzed Well new method technology. According to the characteristics of oil shale strata and the characteristics of similar source rocks, this paper comprehensively discusses oil from 6 aspects of stratigraphic mineral composition estimation, organic carbon content, organic matter type, organic matter maturity, porosity and oil content Shale data interpretation method. As the degree of fracture development in oil shale directly affects its exploitation efficiency, the effective identification and evaluation of cracks is still a difficult problem, so it increases the qualitative and quantitative evaluation methods of oil shale and oil shale fractures. Although this method is still in the development and improvement stage, it is of great significance to the logging evaluation of oil shale.
