SHALE-EVAL高热解温度岩石热解分析仪的研制及其性能评价

Abstract

针对我国下古生界高演化页岩岩石热解分析的需要，研制了SHALE-EVAL高热解温度岩石热解分析仪，突破了国内仪器的600˚C热解温度技术瓶颈，其最高热解温度可达850˚C。对该仪器的性能实验与实际样品测试研究表明，该仪器适合于我国南方高演化烃源岩的热解分析，且性能指标不逊色于法国生产的ROCK-EVAL VI岩石热解分析仪。初步探索了采用该仪器快速测定高演化页岩总有机碳含量(TOC)的方法，发现高演化页岩的TOC值与其800˚C热解参数之间具有良好的数学关系。 Aiming at to make rock pyrolysis experiment be suitable for the high evolution in lower palaeozoic shale, we developed the SHALE-EVAL high temperature rock pyrolysis analyzer; the highest pyroly- tic temperature can achieve to 850˚C, which makes a breakthrough in domestic technology bottlenecks of existing instruments which highest pyrolytic temperature is only 600˚C. By studying the equipment performance and sample testing, we considered that this analyzer is appropriate for pyrolysis analysis of high maturated hydrocarbon source rocks in South China, and its performance indicators are not inferior to ROCK-EVAL VI rock pyrolysis analyzer which is produced by France. We initially explored the method of rapid determination TOC of high maturated shale; there is a mathematical relationship between TOC and the pyrolysis parameters of high maturated shale.
