摘要: 目前页岩油气勘探已逐渐成为国内寻找油气资源的重要领域.页岩油赋存方式和储集空间的多样性、复杂性及勘探的隐蔽性,导致利用测井信息对其认识和评价较为困难,现在页岩油气测井评价技术还处于空白.本文从页岩油赋存方式入手,对影响页岩油储集质量和丰度的关键因素进行了分析;从岩心实验刻度出发,形成了页岩岩相划分方法;通过构建页岩油测井评价体积模型,建立了页岩含油性评价方法和相应的参数计算模型;提出了页岩油有利储集段的概念,并给出了确定有利储集段类别划分的关键参数及其划分方法.用此方法对胜利油区页岩油进行定量评价,取得了较好应用效果.

Abstract: The exploration of shale oil and gas is becoming the emphasis to look for oil and gas resources in China. The occurrence ways and accumulation capability of shale oil, and the are diverse and complex exploration is also hidden which lead to the difficulty of shale oil evaluation using logging information. And so far little study has carried out on shale oil well logging evaluation. In this paper, based on the occurrence ways of shale oil the key factors were analyzed which affect the quality and abundance of shale oil reservoir; Using the core experimental calibration, the method to classify shale lithofacies was formed;After a volume model of shale oil well logging evaluation was constructed, the evaluation method of shale reservpir parameters calculation was established. Then, the concept of favorable reservoir section of the shale oil was proposed to determine key parameters, and classification methods of favorable reservoir type was also formed. Finally, the quantitative evaluation technique above was applied into shale oil formation evaluation of Shengli Oilfield, and the application effects were proved good.
