Method for measuring oil content of shale by using rock pyrolysis instrument

The invention discloses a method for measuring the oil content of shale by using a rock pyrolysis instrument, which comprises the following steps: collecting a shale sample, and crushing the shale sample; carrying out rock pyrolysis on the crushed mud shale sample by adopting gradient heating, and measuring the pyrolysis hydrocarbon content in the mud shale sample; and calculating the oil content of the shale according to the measured pyrolysis hydrocarbon content in the shale sample. An effective and suitable-to-popularize mud shale oil content test and light hydrocarbon compensation calculation method is established based on a rock pyrolysis test technology, and the mud shale oil content test and calculation method is a simple, accurate and generalizable mud shale oil content test and calculation method only using a rock pyrolysis means. 本发明公开了利用岩石热解仪测定泥页岩含油量的方法，包括以下步骤：采集泥页岩样品，将泥页岩样品进行粉碎；采用梯度加热对粉碎的泥页岩样品进行岩石热解，测得泥页岩样品中的热解烃含量；根据测得的泥页岩样品中的热解烃含量，计算泥页岩的含油量。依托于岩石热解测试技术建立了有效且适宜推广的泥页岩含油量测试及轻质烃补偿计算方法，是一种仅用到岩石热解手段的简易
