世界对页岩油的兴趣引起了对俄罗斯非常规资源的高度关注，其中主要属于Bazhenov组（西伯利亚西部）。Bazhenov组的枯竭驱动型开发只能开采地质储量的3%。提高Bazhenov地层采收率的潜在方法之一是热处理，根据专家的说法，该方法可以将采收率提高到30-40%。为了在俄罗斯页岩储层开发中成功引入新的热方法，需要进行实验室测试。这些试验将从科学和技术上证实原位热解的工艺参数。本文研究了高温对巴热诺夫组储层物性的影响。采用GRI方法在岩心破碎上确定了巴治诺夫组储层物性。结果表明，随着温度的升高，孔隙度和基质渗透率呈数倍增大。
World interest in shale oil has provoked high attention to Russian unconventional resources, to which, the Bazhenov Formation (Western Siberia) primarily belongs. Depletion drive type development of the Bazhenov Formation allows producing only 3% of geological reserves. One of the potential method for increasing oil recovery in the Bazhenov Formation is the thermal treatment, which, according to experts, allows rising oil recovery factor to 30-40%. Laboratory tests are needed to successfully introduce new thermal methods for development shale reservoirs in Russia. These tests would allow scientifically and technically substantiating technological parameters of in-situ pyrolysis. This work is concerned with investigation of high temperatures effects on reservoir properties of Bazhenov Formation rocks. Reservoir properties of the Bazhenov Formation were determined on crushed core by the GRI method. It is shown that, the open porosity and matrix permeability are increased in several times with rising temperature.
