摘要

选取松辽盆地西北部的白垩系嫩江组、鄂尔多斯盆地西南部的三叠系延长组7段、柴达木盆地西南部的古近系、准噶尔盆地东部吉木萨尔凹陷的二叠系芦草沟组4块典型页岩样品,通过生烃动力学实验模拟和数值计算,确定其有机质生烃动力学参数。结果表明,有机质生烃活化能与成熟度密切相关,主要分布在197~227 kJ/mol。以此为基础,计算了页岩加热转化生烃所需要的温度。结果表明,在恒温加热条件下,较为理想的加热温度是270~300 ℃,经过50~300 d即可达到90%以上的成烃转化率。持续恒速升温速率条件下,在1~150 ℃/月升温速率条件下,主生烃期对应的温度在225~350 ℃。为了获得较高的经济效益,建议采用相对较快的升温速率（60~150 ℃/月）。通过实际样品生烃动力学模拟和计算,获得了较为可靠的动力学参数,可以为页岩油地下原位加热转化提供更加合理的加热方案。图8表1参28

Abstract

The kinetic parameters of hydrocarbon generation are determined through experimental simulation and mathematical calculation using four typical samples selected from the Cretaceous Nenjiang Formation in the northwest of Songliao Basin, Chang 7 Member of Triassic Yanchang Formation in the southwest of Ordos Basin, Paleogene in the southwest of Qaidam Basin, and Lucaogou Formation of Jimusar Sag in the east of Junggar Basin. The results show that activation energy of hydrocarbon generation of organic matter is closely related to maturity and mainly ranges between 197 kJ/mol and 227 kJ/mol. On this basis, the temperature required for organic matter in shale to convert into oil was calculated. The ideal heating temperature is between 270 ℃ and 300 ℃, and the conversation rate can reach 90% after 50-300 days of heating at constant temperature. When the temperature rises at a constant rate, the temperature corresponding to the major hydrocarbon generation period ranges from 225 to 350 ℃ at the temperature rise rate of 1-150 ℃/month. In order to obtain higher economic benefits, it is suggested to adopt higher temperature rise rate (60-150 ℃/month). The more reliable kinetic parameters obtained can provide a basis for designing more reasonable scheme of in-situ heating conversion.
