摘要

摘要: 针对升温速率、加热时间和油页岩本身的含水率对油页岩原位转化开采物性的影响，利用烃源岩生排烃模拟实验装置，开展了不同升温速率、加热时间和含水率作用下、终温为350℃的油页岩原位热解模拟实验，对热解后油页岩样品进行了核磁共振测试分析，探讨了这些因素对油页岩原位开采热解物性变化的影响。结果表明：较慢的升温速率有利于有机微孔的发育，较快的升温速率有利于微裂缝的发育；恒温时间的增加，可以改善油页岩物性，随着恒温时间的增长，小孔隙逐渐发育成相对大的孔隙；高温水可能作为催化剂、反应物和溶剂参加反应，一方面有利于与有机质反应生成有机孔，另一方面高温水与油页岩矿物可能发生反应，改善了油页岩的物性。

Abstract: An oil shale in situ pyrolysis simulation experiment with different heating rates, heating time and water contents was carried out to assess the influences of these parameters on the physical properties of oil shale in situ conversion production. The physical properties of oil shale in situ conversion production were analyzed using nuclear magnetic resonance T₂ spectra. The results showed that the slow heating rate (the increase of reaction time) was beneficial to the development of organic micro-pores, while the increase of heating rate was beneficial to the development of micro-cracks. With the increase of constant temperature time, the physical properties of oil shale can be improved, and small pores gradually develop into relatively larger pores. High-temperature water may be used as a catalyst, reactant and solvent to participate in the reaction. On the one hand, it is beneficial to react with organic matter to generate organic pores; on the other hand, high-temperature water may react with oil shale minerals, thus improving the physical properties of oil shale.
